IL-34 expression in cancers

Correlation between IL-34 and clinic-pathological characteristics, and Cox's proportional hazards model analysis of prognostic factors for OS in NSCLC patients

The ability of tumor cells to escape immune destruction and their acquired resistance to chemotherapy are major obstacles to effective cancer therapy. Although immune checkpoint therapies such as anti-PD-1 address these issues in part, clinical responses remain limited to a subpopulation of patients. In this report, we identified IL34 produced by cancer cells as a driver of chemoresistance. In particular, we found that IL34 modulated the functions of tumor-associated macrophages to enhance local immunosuppression and to promote the survival of chemoresistant cancer cells by activating AKT signaling. Targeting IL34 in chemoresistant tumors resulted in a remarkable inhibition of tumor growth when accompanied with chemotherapy. Our results define a pathogenic role for IL34 in mediating immunosuppression and chemoresistance and identify it as a tractable target for anticancer therapy.

Glucose toxicity become serious risk factor of type 2 diabetes mellitus. Multiple complication can be caused of the abnormal condition of glucose level in blood. Thus, managing the plasma glucose is one of the strategy to minimize the negative effects of type 2 diabetes mellitus. In this present study, we aimed to virtually evaluate the bioactive compounds from Alpinia galanga as inhibitor agent against alpha-glucosidase, which was known as carbohydrate catabolic enzyme. The 2D structure of ligands were retrieved from PubChem database (pubchem.ncbi.nlm.nih.gov/) and were evaluated based on Lipinski rule of five for ensured the druglike-ness standard, while the sequence and 3D structure of target protein, alpha-glucosidase, was retrieved from UniProt database (https://www.uniprot.org/) and was modelled through SWISS-MODEL (swissmodel.expasy.org/). All ligands used in this study then underwent optimization prior to molecular docking and analyzing procedures. According to our prediction results, we found that galangin and 1's-1'-acetoxychavicol acetate which known as bioactive compounds found in A. galanga have significant potency as inhibitor agents against the alpha-glucosidase due to its binding affinity scores and other physicochemical properties compared to the anti-diabetic drug, mignitol. Thus, from this finding, we have recent starting point to expand the potency of these bioactive compounds, especially for inhibiting the alpha-glucosidase as the novel strategy to reduce the poor prognosis of type 2 diabetes mellitus.

Averrhoa bilimbi L., (Belimbing wuluh), is traditionally used for various antidiabetic, anti-larvicidal, antioxidant, hypoallergenic, antibacterial, antifungal, and anti-inflammatory treatments. This study evaluated 3 extracts (n-hexane, ethyl acetate, and n-butanol) isolated from starfruit flowers for antidiabetic effects using in vitro and in silico methods. Ethyl acetate extract showed the highest activity, followed by n-hexane and n-butanol extracts in inhibiting α-glucosidase. Each extract has an IC50 value of 89.84, 52.88, and 114.86 µg/mL. The active compounds contained in the ethyl acetate extract were determined using LC-MS, and the compounds with the highest retention time were identified as tautomycetin (8.585) and lithocholic acid (8.993). Tautomycetin and lithocholic acid showed promising results in the in silico test. The computational predictions showed that tautomycetin (−6.2 kcal/mol) and lithocholic acid (−10.0 kcal/mol) have better binding affinity values than miglitol (−5.4 kcal/mol).

Herbs and spices have been used for many years as an important source of food ingredients. Recently, herbs and spices have been used as the source of medicinal materials due to its rich-bioactive compounds content. However, the knowledge about the scientific background of these herbs and spices uses in the local community is based on limited data. This work aims to study the perspective of the Tabaru ethnic group toward the use of herbs and spices as an additional food source. This study was conducted between November and December, 2018 in Halmahera Island. The data and information about the use of herbs and spices were collected from 48 locals whose ages ranged between 40 and 89 years. The main occupation of respondents was farming of mainly nutmeg, clove, and coconut. The data were analyzed based on plant uses which included spices, food, and drug use. Data on plant species were analyzed using the Cultural Food Significance Index (CFSI) formula. The results showed that the Tabaru ethnic group used approximately 14 plant species as herbs and spices. According to the CFSI values,herbs and spices in very high significance group include Curcuma longaL. (value of CFSI, 460.8), Cinnamomum burmanni(Nees & T. Nees) Neeex Blume, Myristica fragrans Houtt., Curcuma domestica Valeton, and Zingiber officinale Roscoe (CFSI, 259.2). Moreover, in the high significance category, Capsicum annuum L. is listed with high CFSI score reaching 86.4. In the moderate significance category, we found about four species, namely Ocimum americanum L. and Ocimum americanum L. (CFSI, 48.6), Etlingera heliconiifolia(K. Schum.) AD Poulsen (CFSI, 24.3), Alpinia galanga(L.) Willd. (CFSI, 23,625). Finally, two species of Etlingera elatior(Jack) R.M.Sm. (CFSI, 17.82) and Alpinia eremochlamys K.Schum. (CFSI, 15.53) were in the low significance group. In conclusion, the value of CFSI has a positive correlation to the utilization and the conservation level of herbs and spices of Tabaru ethnic group in Halmahera Island.

Introduction: Sambucus is a genus of the Adoxaceae family and has been widely used as a food and medicinal source. In this study, we aimed to evaluate the effects of S. javanica extracts toward T cells regulation in the 7,12-dimethylbenzene (a) anthracene (DMBA)-exposed mice.Methods: Thirty mice were used in this experiment which divided into six treatment groups and five times repetition. Three-month-old BALB/c mice were administrated with 2.8 mg.kg-1 BW of DMBA as carcinogen agent for ten times within four weeks, then continuously treated with 400 and 800 mg.kg-1 BW of S. javanica berries leaves extracts daily for two weeks. Treatment groups in this study were vehicle as negative control, DMBA 2.8 mg.kg-1 BW as positive control; BD1 group, DMBA 2.8 mg.kg-1 + berries extracts 400 mg.kg-1 BW; BD2 group, DMBA 2.8 mg.kg-1 + berries extracts 800 mg.kg-1 BW; LD1 group, DMBA 2.8 mg.kg-1 + leaves extract 400 mg.kg1 BW; and LD2 group, DMBA 2.8 mg.kg-1 + leaves extract 800 mg.kg-1 BW. The relative number of CD4+CD25+CD62L+ cells and CD4+CD62L+ cells were measured and analyzed by using flow cytometer.Results: DMBA induction decreased the relative number of CD4+CD25+CD62L+ cells while the leaves extract of S. javanica significantly increased their expression. Furthermore, DMBA promoted the relative number of CD4+CD62L+ cells expression while leaves and berries extracts of S. javanica sharply suppressed its expression.Conclusion: The results suggest that, S. javanica extracts may exert their medicinal properties by modulating T cells regulation in DMBA-induced mice.

Aplastic anemia, life-threatened disease, is a hematologic disorder characterised by bone marrow hypoplasia. Multiple modalities such as bone marrow transplantation and immunosuppression treatment have been proposed to ameliorate this entity, however it remains ineffective. Sambucus, a group of herb plants, possesses a broad spectrum of medicinal properties such as antioxidant, insulin-like activity, anticancer and antiviral. However, the study about its activity toward aplastic anemia incidence is based on limited data. Thus, the research aim of this study was to evaluate the immunomodulatory activities of Sambucus javanica in chloramphenicol-induced anemia aplastic mouse model. In this present study, BALB/c mice were administrated with chloramphenicol (CMP) to induce aplastic anemia then followed by S. javanica extracts treatment. Additionally, cellular and molecular aspects were evaluated by flow cytometry and Hematoxylin-Eosin staining. Further analysis showed that S. javanica extracts could promote the population number of regulatory T-cells and naive cytotoxic T-cells. Moreover, those extract also reduced the inflammation and necrotic incidence in CMP-induced mouse aplastic anemia model. Together, these results suggest that S. javanica has therapeutically effect to aplastic anemia by altering the immune system as an immunomodulatory agent.

The E5 protein is the smallest known oncoprotein linked to HPV 16 cancer development. In this study, we determined the potential of asarinin and thiazolo as an inhibitor of the E5 protein through molecular dynamics. The results showed that the binding site is unstable because of its hydrophobic nature and small size, causing considerable changes in the binding site for each of the 3 drugs examined. Except for asarinin, which still interacts with the first hydrophobic domain, they preserved their capacity to prevent endosomal acidification, hyper amplification of the EGFR pathway and contact with BAP31. It may inhibit E5-MHC I interaction. Thiazolo[3,2-a]benzymidazole-3(2H)-one,2-(2-fluorobenzylideno)-7,8-dimethyl (thiazolo) is expected to form more stable protein-ligand complexes than the other 2. However, the SASA, hydrogen bond and DCCM plots show that both compounds are equivalent to HPV 16 E5 protein. HIGHLIGHTS The smallest known oncoprotein associated with cancer development as a result of HPV 16 infection is the E5 protein The SASA, hydrogen bond, and DCCM plots, on the other hand, show that asarinin and thiazolo are equivalent to the HPV 16 E5 protein Thiazolo is predicted to produce more stable protein-ligand complexes than the others because of its unique molecular dynamic properties GRAPHICAL ABSTRACT

Coronaviruses cause mild to severe respiratory infections. The highly contagious SARS-CoV-2 new coronavirus caused a global outbreak of atypical viral pneumonia in late 2019. Acute respiratory distress syndrome, multiple organ failure, respiratory failure, and death can result from the infection. This study aimed to evaluate the possible inhibition activity from numerous medicinal plants' bioactive compounds against three non-structural proteins, namely Nsp1, Nsp2, and Nsp10 of SARS-CoV-2, through the computational study. Molecular docking was performed on the ligands and the target protein. This study investigated multiple criteria, including binding affinity value, location, and chemical interaction. In this present study, we found the top three highest binding affinity values of bioactive compounds against Nisp1, namely cafestol, crocin, and ledene; the top three highest binding affinity values of bioactive compounds against Nisp2, including cafestol, kahweol, and theaflavin 3,3′-digallate; and top three highest binding affinity value of bioactive compounds against Nisp10 namely cafestol, kahweol, and theaflavin-3,3′-digallate. Interestingly, we also found that cafestol, crocin, and theaflavin-3,3’-digallate binds to all target proteins.

Dengue caused by the dengue virus (DENV) is a severe health problem in tropical regions such as Southeast Asia, especially Indonesia. Indonesian have used rhizome as traditional medicine for 1300 years. This study investigated the compounds from Kaempferia galanga, Curcuma longa, Zingiber officinale, Curcuma aeruginosa, Curcuma zanthorrhiza, Alpinia galanga, and Allium sativum as antivirals agents, explicitly targeting the DENV envelope protein to inhibit viral fusion. This study involved 121 bioactive compounds and DENV2's prefusion envelope protein. The virtual screening and molecular docking were done through occupied the Lipinski rule of five checker (http://www.scfbio-iitd.res.in/software/drugdesign/lipinski.jsp) and AutoDock Vina (https://pyrx.sourceforge.io/) respectively. The top nine compounds with the strongest binding affinity were galangin, kampferide, demetoxy curcumin, bisdemethoxycurcumin, β-selinene, 6-(hydroxymethyl)-1,4,4-trimethylbicyclo[3.1.0]hexan-2-ol, piperine, estra-1,3, 5(10)-trien-17β-ol, and curcumin. These compounds' affinity values were significantly lower, around 45-62%, than chloroquine. Most of them interact with the kl hairpin and hydrophobic pocket formed by residues Val130, Leu135, Phe193, Leu198, and Phe279of critical domains that can interfere with the conformational change and rearrangement of protein dimer in the post-fusion stage. This study suggested that the galangin, demethoxycurcumin, and bisdemethoxycurcumin are considered the most potential compounds to be developed as anti-prefusion E DENV2 low-affinity and intense interaction with those. Keywords: DENV2, envelope protein, in silico, viral fusion, viral infection

Purpose: Accumulating evidence shows the genus of Sambucus exerts a broad spectrum ofmedicinal potencies such as anticancer, antiviral, antibacterial, and antidiabetes. Based on theprevious studies, we hypothesized that bioactive compounds of Sambucus might alter severalbiological systems, including the immune system. Therefore, this study extensively aimed toevaluate the immunomodulatory activities of Sambucus javanica extracts in 7,12-dimethylbenz[a]anthracene (DMBA)-treated BALB/c mouse.Methods: The experimental mice were orally administrated with 2.8 mg.kg-1 BW of DMBA forten times within a month. After that, the mice were treated by S. javanica berries and leavesextracts for 2 weeks. Subsequently, the inflammation rate was evaluated by using flow cytometryanalysis, whereas the necrosis incidences were observed by hematoxylin & eosin staining.Results: Based on the results, we found the expression of tumor necrosis factor alpha (TNF-α)and interferon gamma (IFN-ɣ) were increased however after treated by S. javanica berries andleaves extracts were significantly decreased. In the same way, necrosis incidence was increasedin the DMBA-treated group however it was diminished with S. javanica extracts treatment.Conclusion: Together, these results suggested that S. javanica extracts have immunomodulatoryactivities to suppress inflammation and reduce necrosis incidence in experimental mice.

Nicotine dependence can cause numerous adverse effects, especially cardiovascular, cancer, respiratory, and gastrointestinal diseases. In order to minimize the manifestation of nicotine, inhibition on the receptor's binding site is needed. Our previous in silico study shows the activity of several bioactive compounds from Camelia sinensis, Orthosipon aristatus, and Moringa oleifera might be potent as α-3 nicotinic acetylcholine receptor. Thus, in this present study, we extend the screening of inhibitor potency from Kaempferia pandurata, Camelia sinensis, Centella asiatica, Moringa oleifera, and Orthosipon aristatus bioactive compounds against the α-2 NAchR. In silico approach was performed to screen and predict the possibility of drug-likeness and medicinal plant properties of bioactive compounds. The 2D and 3D structures of ligands and protein were retrieved from PubChem and SWISS Model, respectively. The molecular docking strategy and optimization, also visualization were occupied as our previous study. The present findings show that the bioactive compounds from K. pandurata, C. sinensis, C. asiatica, M. oleifera, and O. aristatus have the possibility to be potential α-5 NAchR inhibitor.

Recently, diabetes mellitus (DM) still become the top health problem worldwide. Several reports showed the incidence and death number of this disease are increasing every year. Therefore, the strategy to overcome DM is crucially needed. Another possible way to minimize the adverse effect of DM is by understanding the immunological activities and properties, which lead us to have another option or insight to treat DM. Thus, in this present study, we aim to evaluate the production of granzyme by CD8 T cells and NK.1.1 natural killer (NK) cells after treated by the combination of Momordica charantia and Averrhoa bilimbi extract in streptozotocin (STZ) induced mice. The animal mice model was firstly induced by STZ, then followed by the Momordica charantia and Averrhoa bilimbi extract treatment. Finally, the expression number of granzyme from CD8 T cells and NK1.1 NK cells was evaluated using flow cytometry (FACS CaliburTM). According to our observation, we found that the granzyme is not produced by both CD8 T cells and NK1.1 NK cells, even after treated by the Momordica charantia and Averrhoa bilimbi extract.

Liver fibrosis is the initial step of hepatocellular carcinoma (HCC). Liver fibrosis can be triggered by metabolic perturbation, viral infection, and harmful chemical exposure. This in vivo study aims to investigate the potential of Moringa oleifera leaf powder (MOLP) from Madura Island as the future candidate for antifibrosis and hepatoprotective agent. The study was conducted to evaluate the alteration of circulating levels of liver injury marker-linked liver fibrosis development, Alanine Aminotransferase (ALT), and Aspartate Aminotransferase (AST). The animal model was prepared using Balb-c mice age 6-8 weeks treated by intraperitoneal injection of carbon tetrachloride (CCl4) dose 1 µL/g of BW for six weeks to induce liver fibrosis. The experimental groups were received green materials Moringa oleifera leaf powder solution with a serial dosage by peroral administration for six weeks. Interestingly, our animal model's preliminary study shows that the administration of green materials MOLP can alleviate the increase of ALT and AST. MOLP treatment can also prevent significant changes in liver weight, morphology, and even histological feature-associated liver injury and fibrosis. Hence, MOLP Madura Island may become the future green materials source for cancer herbal drug development.

Chronic inflammation is the initial stage of liver fibrosis-related hepatocellular carcinoma (HCC) development. Also, HCC is a global disease resulting from several etiological factors. HCC incidence can be triggered by alcohol abuse, non-alcoholic steatohepatitis (NASH), viral hepatitis B (HBV), viral hepatitis C (HCV), and non-alcoholic fatty liver disease (NAFLD). Liver chronic inflammation significantly correlates to TNF-α (Tumor Necrosis Factor-α) and IL-6 (interleukin 6) expression. This laboratory work aimed to investigate the effect of green material Moringa oleifera leaf powder (MOLP) on the expression of both pro-inflammatory cytokines. A semi-quantitative approach quantified the expression of TNF-α and IL-6. This research was conducted using an animal model induced by intraperitoneal injection of CCl4 solution. The results showed that green material Moringa oleifera could reduce IL-6 and TNF-α expression. Importantly, MOLP exposure can decrease the pro-inflammatory cell population in the liver parenchymal area. Hence, the application of green material Moringa oleifera might be potential as the local bioresources agent against liver inflammation-linked fibrosis. The exploration of MOLP in the future drug discovery model may significantly contribute to the prevention of hepatocellular carcinoma.

Rohman F, Putra WE. 2021. Short Communication: The bioinformatics perspective of Foeniculum vulgare fruit's bioactive compounds as natural anti-hyperglycemic against alpha-glucosidase. Biodiversitas 22: 79-84. The management in controlling the blood glucose level is crucially necessary to be promoted. Many reports showed the harmful effect of glucose toxicity, most of them are the cluster of metabolic disorder. Nowadays, natural products are getting much attention on health issues. The uses of medicinal plants for drug materials are dramatically increasing. In our previous study about local medicinal plants identification, we found that Tengger Tribe in Indonesia uses numerous type of species, including Foeniculum vulgare which was widely found and occupied as traditional medicine by Tengger Tribe in the area of Taman Nasional Bromo Tengger Semeru, East Java, Indonesia. According to their local belief, F. vulgare has been used to ameliorate several types of diseases. Thus, in this present study, we aimed to virtually evaluate the bioactive compounds of F. vulgare for anti-hyperglycemic against the alpha-glucosidase. We performed computational prediction of ligands-protein interaction by molecular docking approaches. The 2D structure of ligands and 3D structure of target protein were retrieved via the database. The natural compound's structure was then evaluated by the Lipinski rule of five to indicate whether it can be categorized as drug-like or not. Moreover, according to our simulation, F. vulgare fruit's bioactive compounds including sterol, anethole, and fenchone might have therapeutic effect to reduce the hyperglycemia incidence by inhibiting the alpha-glucosidase activity. Compared to miglitol, an alpha-glucosidase inhibitor, Sterol have the most significant binding affinity against the alpha-glucosidase. Therefore, these findings suggest that sterol, anethole, and fenchone might be potential new candidates for alpha-glucosidase inhibitors.

Dengue is a severe health problem, especially in under-developing countries like Indonesia. The government and the community have made various efforts. However, the current programs are focusing on controlling disease vector. Medical treatment so far only treats the symptoms. On the other hand, the development of antiviral compounds has been dominated by synthetic compounds which may have serious side effects. The potential of natural compounds in Asia is still largely unexplored. Dengue virus nonstructural protein 5 (NS5) is highly conserved in all serotypes. This study aims to screen several potential natural compounds to be developed as specific antiviral compounds targeting DENV NS5. This research conducted by using in silico approaches including data mining, molecular docking, and 2D-3D visualization. About 170 compounds from 88 organisms analyzed to get the top nine compounds with the highest affinity against NS5 protein. The top nine compounds are from the halichondramide, trigocherriolide, quinadoline, tryptoquivaline, and zingiberene groups. The docking results showed that these potential compounds have an affinity of about 67-100% higher than ribavirin. The visualization results show that these compounds are grouped into three different binding sites. They are RdRP, MTase, and the junction. Compounds that bind in RdRP are thought to interfere with the process of RNA viral synthesis, compounds that bind to MTase are thought to disrupt the viral RNA capping process, while compounds that bind between the two domains are thought to interfere NS5 structural integrity. The compound with the highest affinity is halishigamide A. Halishigamide A is known to have antimicrobial properties, but the action mechanism is still unknown. Compared to the control drug, the halishigamide A tends to have more dynamic movement and interaction to the target protein’s binding site due to its residues’ chemicals motive. Together, these results showed the potency of natural products as specific antiviral compounds targeting DENV NS5.

Yani A, Amin M, Rohman F, Suarsini E, Putra WE. 2020. Profiling indigenous lead-reducing bacteria from Tempe Lake, South Sulawesi, Indonesia as bioremediation agents. Biodiversitas 21: 4778-4786. The pollution of heavy metals by anthropogenic activities in freshwater, especially in lakes, reduces the quality and endangers the existence of aquatic flora and fauna. This happens in Lake Tempe, which is located, in South Sulawesi, Indonesia. The study aimed to evaluate the content of heavy metals, isolation, and identify a lead reduction of indigenous bacteria as candidates for bioremediation agents. It began by examining the level of cadmium (Cd), copper (Cu), and lead (Pb) in seven sampling sites of Tempe Lake. Furthermore, propagation and isolation, morphological observation, laboratory-scale reduction tests, and species identification of potential bacteria reduction Pb were performed by using 16s rDNA. The reduction test to Pb was measured using Atomic Absorption Spectrometry (AAS), and the research data were analyzed using One-Way ANOVA with the Duncan advanced method. The results showed that the Cd, Cu, and Pb content of the seven sampling points exceeded the water quality standard Following the Indonesian Government Regulation (IGR) and WHO standards. Pb has the highest concentration among the other heavy metals in the water sample reaching 0.40 mg/L. Four bacterial isolates could grow on Pb-enriched media (isolates A, B, C, and D). The Bacillus form was found in two different species bacteria (isolate A and D), while the cocci shape was found in two other species (isolate B and C). Those all Gram-negative bacteria were observed to be a reduction to Pb exposure within a bacterial medium. Interestingly, these indigenous bacteria could decrease Pb concentration ranging from 7.45 to 3.48 ppm for seven days. Furthermore, the sequencing data showed that the indigenous bacteria (isolate D) had a 99.90% similarity to the Comamonas testosteroni strain S-2 constructed using Neighbor-joining phylogenetic analysis. Therefore, the indigenous bacteria C. testosteroni strain S-2 from Tempe lake may be proposed as a bioremediation agent to reduce Pb the water contaminants.

Indonesia is considered as a mega-biodiversity country that has a massive amount of vascular and non-vascular plants. The tropical environment condition of Indonesia could support the growth of macrofungi. Information about edible macrofungi from the Forest of Lombok Island is based on limited data. This research aims to characterize the edible macrofungi at Kerandangan Protected Forest & Natural Park, West Lombok Regency, Indonesia. This research was a descriptive and explorative study. The edible mushrooms were observed through the Cruise method by following the particular track inside the forest. The sample found in the forest then documented and evaluated. A morphological analysis procedure was performed to assess the profile and similarity between the microscopic evaluations with the mushrooms identification book. In this study, we also offered a phylogeny analysis based on morphological characters similarity. The Dendogram tree was reconstructed using PAST 3.0. software. The result showed that there are eight species of edible mushrooms found that were group into Basidiomycota, namely, Termitomyces clypeatus, Termitomyces umkowaan, Termitomyces sp.1, Pleorotus flabelatus, Pleurotus ostreatus, Coprinus desimenatus, Tremella fuciformis, and Polyporus sp. All of them involved in Basidiomycota. Based on characterization and identification, the species are grouped into three Ordos and five Families. Most of the edible macrofungi found at Kerandangan Protected Forest & Natural Park growth at soil and deadwood.

Nuclear factor kappa B (NF-κB) is known as master of regulation due to its multiple roles in biological system, including metabolism, inflammation, or even diseases like cancer. The downstream phosphorylation of NF-κB complex is affected by the activity of inhibitor of nuclear factor kappa-B kinase subunit beta (IKK-B). Thus, in this study, we aimed to evaluate the bioactive compounds of Zingeber officinale as inhibitor agent against the IKK-B. The virtual screening evaluation was based on the interaction activity and binding free energy among the protein and the ligands. The virtual chemical structures of bioactive compounds from Zingiber officinale and protein structure of IKK-B were obtained from Pubchem web server and PDB, respectively. Molecular docking, visualization, and data analysis were performed by computation approach. In this study, we found that 6-Shogaol might be potential as drug like molecule for anti-inflammation compared to other compounds. Importantly, further study is needed to evaluate the biological mechanism of 6-Shogaol inhibit the IKK-B activity.

Recent trends in health care demonstrate the significant use of herbs as preventive or therapeutic agents against multiple types of diseases, including respiratory disorder caused by cigarette smoking. Thus, in this present study, we explored the potential of medicinal plants’ phytochemical compounds as an inhibitor against the human α-3 nicotinic acetylcholine receptor (NAchR). The computation prediction was performed to evaluate the energy and possible interactions among the ligands and target protein. Specifically, the 2D structure of bioactive compounds was retrieved from PubChem database. On the other hand, the protein sequences of human α-3 NAchR were obtained from Uniprot and protein database. The 3D structure was then built up through SWISS-MODEL. Additionally, protein and ligand preparation was employed to optimize the molecular interaction results. The final step of this screening through molecular docking approach was performed using data visualization and analysis. In this study, we found that there are three potential compounds as an inhibitor against α-3 NAchR based on their energy-free binding, namely, Theaflavin-3-Gallate, Asiaticoside, and Theaflavin-3,3-Digallate. Therefore, work indicates that the medicinal plants’ bioactive compounds might be the potential to develop as inhibitory agents for α-3 NAchR to minimize the negative effect of nicotine.

The study of bird community structure was carried out in the water sources area in “Malang Raya”. Birds have an important role in sustaining habitat conditions and ecosystem stability. The purpose of this study is to evaluate the condition and charachters of habitats and ecosystems of water sources, based on the bird’s community structure. In this present study, visual observation was used by the cruising method, then counting the number of species and number of individuals within a radius of 200 meters from the water source as a focal point of observation. Those methods were performed with three times replications a day during March 2019. Data collection was done at eight water sources, including Kendedes, Waras, Taman, Sira, Jenon, Wendit, Brantas, and Cangar. The analyses showed that the diversity index (H’) gain 2.88 scores, 0.92 scores for evenness (E), and 5.25 for species richness (R). Based on the results, We interpret that the ecosystem condition at eight sites of the water source can still support as a bird habitat under the carrying capacity. Overall, habitat and ecosystem conditions in the Malang Raya water sources still tend to be stable, with low ecological pressure.

Hematopoiesis play important roles on maintaining body homeostasis. Dexamethasone (Dex) known as synthetic glucocorticoids and widely affect many regulations i.e. immune system, inflammation, reproduction and all aspects of metabolism. Generally Dex were used as therapeutic agentsto ameliorate many kind of diseases including cancer and auto-immune diseases. The aims of this research were to investigate the effect of Dex administration toward expression of hematopoietic stem cells and blood progenitor cells. Two weeks old BALB/c mice were used and treated with 3 groups of Dex administration i.e. untreated-mice, 0.5 mg/kg BW, and 10 mg/kg BW. Mice were sacrificed on day-7 after administration of Dex. The bone marrow stromal cells were isolated, then followed by flow cytometry analysis. The result showed that, Dex administration with dose 0.5 mg/kg BW significantly increase the expression of hematopoietic stem cells, CD34 + , chemokines, SDF-1 + , erythroid progenitor cells, Gr-1 - TER-119 + , granulocytes, Gr-1 + , and B progenitor cells, B220 + .

Hematopoiesis has a pivotal role in the maintenance of body homeostasis. Ironically, several hematological disorder caused by chemicals, drugs, and other environmental factors lead to severe bone marrow failure. Current treatments like stem cell transplantation and immunosuppression remain ineffective to ameliorate this diseases. Therefore, a newtreatment to overcome this entity is necessary, one of them by promoting the usage of medicinal plants. Thus, this study aimed to evaluate the hematopoiesis potency of S. javanica berries and leaves extracts in chloramphenicol (CMP)-induced aplastic anemia mice model. In this present study, several types of blood progenitor cell such as TER-119+VLA-4+ erythrocytes lineage, Gr-1+ granulocytes, and B220+ Bcell progenitor cells were evaluated by flow cytometry analysis. Accordingly, we revealed that S. javanica berries and leaves extracts significantly promoted TER-119+VLA-4+ erythrocytes lineage and Gr-1+ granulocytes after exposed by CMP. Thus, these results suggested that S. javanica berries and leaves extracts might have hematopoiesis activity in CMP-induced aplastic anemia mice model.

The ability of tumor cells to escape immune destruction and their acquired resistance to chemotherapy are major obstacles to effective cancer therapy. Although immune checkpoint therapies such as anti-PD-1 address these issues in part, clinical responses remain limited to a subpopulation of patients. In this report, we identified IL34 produced by cancer cells as a driver of chemoresistance. In particular, we found that IL34 modulated the functions of tumor-associated macrophages to enhance local immunosuppression and to promote the survival of chemoresistant cancer cells by activating AKT signaling. Targeting IL34 in chemoresistant tumors resulted in a remarkable inhibition of tumor growth when accompanied with chemotherapy. Our results define a pathogenic role for IL34 in mediating immunosuppression and chemoresistance and identify it as a tractable target for anticancer therapy.
