Ulcerative Colitis (UC) is a persistent inflammatory condition of the colon that occurs due to the disruption in the epithelial barrier and immunological responses. In UC the episodes of inflammation are relapsing and remitting in the colonic mucosa. Etrasimod, an S1P receptor modulator, is a potential therapy for UC. The goal of this review is to compile the data related to effectiveness and safety studies of etrasimod in the treatment of UC. Pre-clinical and clinical studies examine how etrasimod affects many aspects of UC pathophysiology, including S1P receptor regulation, immune cell migration, and improved gut barrier function. Etrasimod mainly inhibits the lymphocytes entry into the peripheral blood and prevents the migration of lymphocytes into the inflammation cycle. This article gives a comprehensive account of several factors linked to etrasimod and ulcerative colitis, including the pathology of ulcerative colitis, US-FDA approved treatment for UC, mechanism of action of etrasimod, pharmacokinetic, pharmacodynamic data of etrasimod, reported risk and related aspects and completed and ongoing clinical trials.

Pompe disease is a lysosomal storage disease characterized by impaired glycogen breakdown due to an acid α-glucosidase (GAA) enzyme deficiency. Without therapy, children with the severe infantile form do not survive past their first year of life. POMBILITI which is intended to treat late-onset Pompe disease. The enzyme cipaglucosidase alfa-atga, which is produced from Chinese Hamster Ovary (CHO) cells, is a component of this novel drug. This enzyme is produced using a highly developed process known as perfusion methodology. Recombinant human α-glucosidase (rhGAA) is expressed and produced in CHO cells using the perfusion process. This drug helps to treat Pompe disease by the breakdown of glycogen within lysosomes. Late-onset Pompe disease is characterized by a deficiency in Alpha glucosidase, leading to the accumulation of glycogen within lysosomes and subsequent cellular dysfunction. POMBILITI's targeted approach involves the administration of the rhGAA enzyme, providing a therapeutic replacement for the deficient natural enzyme. This drug aims to restore the normal physiological function of lysosomes, thereby mitigating the impact of Pompe disease on affected individuals. The current study is focused on the drug cipaglucosidase alfa-atga which the FDA has approved for the treatment of Pompe disease on 28 September 2023.

Introduction: Soil salinity poses a severe threat to rice production, resulting in stunted growth, leaf damage, and substantial yield losses. This study focuses on developing an early maturing seedling stage salinity tolerant rice variety by integrating conventional breeding methods with marker assisted breeding (MAB) approaches.Methods: Seedling-stage salinity tolerance Quantitative Trait Locus (QTL) “Saltol” from the salt-tolerant parent FL478 was introduced into the high-yielding but salt-sensitive rice variety ADT 45. This was achieved through a combination of conventional breeding and MAB. The breeding process involved rigorous selection, screening, and physiological parameter assessments.Results: KKL(R) 3 (KR 15066) identified as the top performing Recombinant Inbred Line (RIL), consistently demonstrating maximum mean grain yields under both salinity (3435.6 kg/ha) and normal (6421.8 kg/ha) conditions. In comparison to the early maturing, salt-tolerant national check variety CSR 10, KKL(R) 3 exhibited a substantial yield increase over 50%.Discussion: The notable improvement observed in KKL(R) 3 positions it as a promising variety for release, offering a reliable solution to maximize yields, ensure food security, and promote agricultural sustainability in both saline and non-saline environments. The study highlights the effectiveness of MAB in developing salt-tolerant rice varieties and emphasizes the significance of the Saltol QTL in enhancing seedling stage salinity tolerance. The potential release of KKL(R) 3 has the capacity to revolutionize rice production in salt affected regions, providing farmers with a reliable solution to maximize yields and contribute to food security while ensuring agricultural sustainability.

Low-temperature stress (LTS) drastically affects vegetative and reproductive growth in fruit crops leading to a gross reduction in the yield and loss in product quality. Among the fruit crops, temperate fruits, during the period of evolution, have developed the mechanism of tolerance, i.e., adaptive capability to chilling and freezing when exposed to LTS. However, tropical and sub-tropical fruit crops are most vulnerable to LTS. As a result, fruit crops respond to LTS by inducing the expression of LTS related genes, which is for climatic acclimatization. The activation of the stress-responsive gene leads to changes in physiological and biochemical mechanisms such as photosynthesis, chlorophyll biosynthesis, respiration, membrane composition changes, alteration in protein synthesis, increased antioxidant activity, altered levels of metabolites, and signaling pathways that enhance their tolerance/resistance and alleviate the damage caused due to LTS and chilling injury. The gene induction mechanism has been investigated extensively in the model crop Arabidopsis and several winter kinds of cereal. The ICE1 (inducer of C-repeat binding factor expression 1) and the CBF (C-repeat binding factor) transcriptional cascade are involved in transcriptional control. The functions of various CBFs and aquaporin genes were well studied in crop plants and their role in multiple stresses including cold stresses is deciphered. In addition, tissue nutrients and plant growth regulators like ABA, ethylene, jasmonic acid etc., also play a significant role in alleviating the LTS and chilling injury in fruit crops. However, these physiological, biochemical and molecular understanding of LTS tolerance/resistance are restricted to few of the temperate and tropical fruit crops. Therefore, a better understanding of cold tolerance’s underlying physio-biochemical and molecular components in fruit crops is required under open and simulated LTS. The understanding of LTS tolerance/resistance mechanism will lay the foundation for tailoring the novel fruit genotypes for successful crop production under erratic weather conditions.

Rice is the major staple food crop for more than 50% of the world’s total population, and its production is of immense importance for global food security. As a photophilic plant, its yield is governed by the quality and duration of light. Like all photosynthesizing plants, rice perceives the changes in the intensity of environmental light using phytochromes as photoreceptors, and it initiates a morphological response that is termed as the shade-avoidance response (SAR). Phytochromes (PHYs) are the most important photoreceptor family, and they are primarily responsible for the absorption of the red (R) and far-red (FR) spectra of light. In our endeavor, we identified the morphological differences between two contrasting cultivars of rice: IR-64 (low-light susceptible) and Swarnaprabha (low-light tolerant), and we observed the phenological differences in their growth in response to the reduced light conditions. In order to create genomic resources for low-light tolerant rice, we constructed a subgenomic library of Swarnaprabha that expedited our efforts to isolate light-responsive photoreceptors. The titer of the library was found to be 3.22 × 105 cfu/mL, and the constructed library comprised clones of 4–9 kb in length. The library was found to be highly efficient as per the number of recombinant clones. The subgenomic library will serve as a genomic resource for the Gramineae community to isolate photoreceptors and other genes from rice.
