Abstract

MicroRNAs are involved in the pathogenesis of various human malignant tumors. This study aims to explore the role of miR-513b-5p in the malignant proliferation of retinoblastoma (RB) cells and its potential molecular mechanisms. The function-gain and function-loss experiments were performed in Weri-RB1 cells using miR-513b-5 mimics and inhibitors. miR-513b-5p mimics inhibited the proliferation and clone formation and promoted apoptosis of Weri-RB1 cells. In contrast, the miR-513b-5p inhibitor promoted the proliferation and clone formation of Weri-RB1 cells and inhibited cell apoptosis. miR-513b-5p can directly bind to the 3′UTR region of TRIB1 mRNA, and inhibit its protein expression. Overexpression of TRIB1 promoted the proliferation and cloning of Weri-RB1 cells but inhibited their apoptosis. The knockdown of TRIB1 inhibited the proliferation and clone formation of Weri-RB1 cells and promoted cell apoptosis. In addition, miR-513b-5p mimics neutralized the effects of TRIB1 overexpression on the proliferation and apoptosis of Weri-RB1 cells. Finally, miR-513b-5p can inhibit the phosphorylation level of AKT, mTOR, and p70, while TRIB1 played the opposite role. miR-513b-5p inhibits the malignant proliferation of Weri-RB1 cells by repressing the expression of TRIB1. miR-513b-5p and TRIB1 may be the biomarkers and/or key targets for clinical diagnosis and treatment of RB.

Abstract

At present, the global concern about food safety and environmental pollution is increasing day by day. Reducing the use of toxic and harmful additives such as antibiotics, hormones, and chemicals in livestock and poultry feed, developing green, safe, efficient, and low-residue additives, ensuring consumers' health, and improving the ecological environment are the focus of animal husbandry at present. Flavonoids are secondary metabolites of plants, which widely exist in bark, root, stem, leaf, fruit, and seeds of plants. They have many biological activities such as anti-inflammation, anti-oxidation, reducing oxidative stress, protecting intestinal mucosa, improving intestinal flora structure, promoting growth, and regulating immunity, etc. They can improve animal production performance and product quality, and have potential development value to enhance the economic benefits of farms. In this paper, the role of flavonoids and their application in livestock and poultry breeding were reviewed, and the application research progress of flavonoids in calves and adult cattle was emphasized, to provide a reference for its rational application in cattle production at different growth stages.

Abstract

Neohelicomyces species are a group of helicosporous hyphomycetes with the potential to produce secondary metabolites. During our investigation of helicosporous fungi, six collections were isolated from both terrestrial and freshwater habitats in Guizhou Province, China. Based on multigene phylogenetic analysis (ITS, LSU, tef1α and rpb2), coupled with morphological data, three new Neohelicomyces species, viz. N. guizhouensis, N. helicosporus and N. hydei were established. A list of accepted Neohelicomyces species with molecular data was provided. The strain of Neohelicomyces pallidus (UAMH 10535) was synonymised under N. denticulatus based on molecular data. [ABSTRACT FROM AUTHOR]

Abstract

Acute lung injury (ALI) is a serious inflammatory disease with high morbidity and mortality. Rosavin is an anti-inflammatory and antioxidant phenylpropanoid and glucoside, which is isolated from Rhodiola rosea L. However, its potential molecular mechanisms and whether it has protective effects against lipopolysaccharide (LPS)-induced ALI remain to be elucidated. To assess the in vitro anti-inflammatory effects and anti-lung injury activity of rosavin, RAW264.7 and A549 cells were stimulated using 1 μg/mL LPS. Rosavin attenuated LPS-induced activation of the TLR-4/NF-κB signaling pathway in RAW264.7 cells and inhibited LPS-induced release of inflammatory factors in A549 cells. A mouse model of acute lung injury was constructed by intraperitoneal injection of 5 mg/kg LPS to observe the therapeutic effect of rosavin. Transcriptomics analysis and Western blot assays were utilized to verify the molecular mechanism, rosavin (20, 40, and 80 mg/kg) dose-dependently ameliorated histopathological alterations, reduced the levels of inflammatory factors, and inhibited the TLR-4/NF-κB/MAPK signaling pathway and apoptosis activation. Rosavin is a promising therapeutic candidate for acute lung injury by inhibiting the TLR-4/NF-κB/MAPK pathway. [ABSTRACT FROM AUTHOR]

Abstract

BACKGROUND Solid sampling technology applied in soil sample measurement has the limitation of sample size, and cannot be applied to the mainstream element analysis instrument. OBJECTIVES To determine the trace elements by smashing soil samples to micron scale by high-speed grinding technology and under the action of a dispersant. METHODS The ultra-fine grinding technology of soil samples was systematically studied. The sample was crushed to micron level in a few minutes in an ethanol medium. The prepared solid suspension was directly measured by ICP-MS, avoiding blockage of pneumatic atomizers. RESULTS The determination of the reference materials shows that the solid suspension still has interference when the particle size is 6.8μm. By adding a small amount of hydrofluoric acid and nitric acid to modify the solid suspension, the solid particle size was reduced and thereby the impact of the sample size was reduced. The 13 trace elements of lithium, beryllium, vanadium, chromium, nickel, copper, zinc, rubidium, strontium, cadmium, cesium, barium and lead were successfully determined by ICP-MS. Accuracy experiment showed that the maximum relative error is 10.5%±3% and most of the elements have a relative error less than 5%. The precision experiment showed that most elements have a relative standard deviation (RSD) of less than 5.4%. CONCLUSIONS The determination results meet the requirements of DZ/G 0130-2006 'Test of Geology and Mineral Resources Quality Management Standards'.
