L-type lectin receptor kinases (LECRK) plays a significant role in biotic and abiotic stress response against environmental stimuli in plants. In the Arabidopsis model plant, a total of 45 LECRK was identified but function elucidation is still unresolved. This study carried out a comprehensive analysis of the SNPs associated with L-type lectin protein and how these mutations affect the structure and function of the protein.

Fibronectin type-III domain containing protein-5 (FNDC5), predominantly expressed in skeletal muscles, encodes FNDC5 transmembrane-protein. A segment of this protein is cleaved and secreted into blood as irisin, which promotes browning of white adipose tissue, leading to energy expenditure. It functions synergistically with fibroblast growth factor-21 (FGF21).

Aims: Bisphenol A (BPA), xenoestrogen, is an environmental toxicant, that generates oxidative stress leading to cardiotoxicity. The oxidative stress can be neutralized by natural and synthetic antioxidants. The present study elucidates the highly selective antioxidative potential of synthetic tetra aniline polymers Es-37 and L-37 against Bisphenol A-induced cardiac cellular impairments and the role of miRNA-15a-5p in the regulation of different apoptotic proteins.

Cancer is a disease of mutation and lifestyle modifications. A large number of normal genes can transform normal cells to cancer cells due to their deregulations including overexpression and loss of expression. Signal transduction is a complex signaling process that involves multiple interactions and different functions.

This study aims to determine UV-B resistance and to investigate computational analysis and antioxidant potential of methoxy-flavones of Micromonospora aurantiaca TMC-15 isolated from Thal Desert, Pakistan. The cellular extract was purified through solid-phase extraction and UV-Vis spectrum analysis indicated absorption peaks at λ 250 nm, 343 nm, and 380 nm that revealed the presence of methoxy-flavones named eupatilin and 5-hydroxyauranetin. The flavones were evaluated for their antioxidant as well as protein and lipid peroxidation inhibition potential using di(phenyl)-(2,4,6-trinitrophenyl) iminoazanium (DPPH), 2,4-dinitrophenyl hydrazine (DNPH), and thiobarbituric acid reactive substances (TBARS) assays, respectively.

Cutaneous Leishmaniasis (CL), a neglected vector-borne disease caused by protozoan parasite Leishmania major (), is a major public health concern, and the development of new strategies to reduce the disease incidence has become a top priority. Advances in immunoinformatics and in-silico epitope prediction could be a promising approach to designing a finest vaccine candidate. In this study, we aimed to design a peptide-based vaccine against CL using computational tools and identified ten B-cell-derived T-cell epitopes from the glycoprotein gp63 of .

() is a free-living thermophilic amoeba of fresh water and soil. The amoeba primarily feeds on bacteria but can be transmitted to humans upon contact with freshwater sources. Furthermore, this brain-eating amoeba enters the human body through the nose and travels to the brain to cause primary amebic meningoencephalitis (PAM).

Article Synopsis
  • The study investigated the pharmacological effects of various fractions and rutin from D. Don, focusing on their antidiarrheal, antisecretory, and antiulcer properties in animal models.
  • The results indicated that these extracts provided dose-dependent protection against diarrhea, inhibited intestinal fluid secretions, and relaxed contractions in gastrointestinal preparations.
  • Toxicology studies confirmed that the extracts are safe for consumption at doses up to 2000 mg/kg, and further analyses showed potential mechanisms of action through the modulation of specific ion channels and inflammation markers.

is a Gram-negative bacterium from the family and genus . The pathogen is a causative agent of gastroenteritis, cellulitis, and bacteremia. The increasing antibiotic resistance pattern of the pathogen prompts the efforts to develop a vaccine to prevent dissemination of the bacteria and stop the spread of antibiotic resistance (AR) determinants.

Article Synopsis
  • Biallelic mutations in the ZMPSTE24 gene are linked to two conditions: mandibuloacral dysplasia with type B lipodystrophy (MADB) and lethal restrictive dermopathy (RD), with severity depending on enzyme activity.
  • The study identified a new homozygous frameshift mutation in a family with MADB, which creates an alternative translation initiation site due to a one base pair insertion.
  • This alternative mechanism may explain the less severe clinical outcomes seen in individuals with this mutation, highlighting the importance of analyzing N-terminal variants that can affect how proteins are produced.

The ongoing pandemic of COVID-19 has elaborated an idiosyncratic pattern of SARS-CoV-2-induced symptoms in the human host. Some populations have succumbed to the SARS-CoV-2 infection in large numbers during this pandemic, whereas others have shown a resilient side by manifesting only milder or no symptoms at all. This observation has relayed the onus of the heterogeneous pattern of SARS-CoV-2-induced critical illness among different populations to the host genetic factors.
