Role of Mycobacterium tuberculosis DinG and UvrD helicases in unwinding G-quadruplex DNA
Recent studies have demonstrated the role of E. coli UvrD as a replicative helicase that facilitates replication of rolling circle plasmids. Along with dinG and rep helicase, UvrD a so-called “accessory helicase” removes ...
Understanding the Mechanism of Double-strand Break Repair and Genome Fragility in Mammalian Mitochondria
Mitochondria are semiautonomous organelles in a cell as they have their own
genome that replicates independently. It plays a major role in oxidative phosphorylation due
to which mitochondrial DNA (mtDNA) is frequently ...
Studies on the post-transcriptional regulation of genes of glutamate utilization pathway in Pichia pastoris and a role for Retrograde regulation protein 1
The methylotrophic yeast, Pichia pastoris can utilize compounds such as glucose, glycerol, methanol, acetate, amino acids, or oleic acid as the sole source of carbon. However, the regulation of synthesis of key enzymes of ...
Untangling the Helicobacter pylori genome: Deciphering the significance of zinc finger motif(s) in Topoisomerase I catalysis
Helicobacter pylori, a human pathogen dominating gastric microbial population, displays differential gene expression during various stages of stomach colonization. Topoisomerases play a crucial role in maintaining DNA ...
Immunomodulatory effects of 7-hydroxy frullanolide, a plant-based sesquiterpene lactone, in inhibiting immune cell responses and roles of disease and vaccination outcomes on Covid-19 mortality
Immunomodulation is a process by which the immune response of the host is either enhanced or
suppressed due to various factors which either protects or makes the host more susceptible to
particular diseases. Immunomodulators ...
Establishment of human ectopic liver tissue in immunocompromised mice as a model for Hepatitis C Virus studies
Infection with hepatitis C virus (HCV) leads to an inflammatory condition which may progress to liver cirrhosis and in some cases, hepato-cellular carcinoma. Though, new drugs are being added to the list of HCV therapeutics, ...
Comparative evaluation of retrograde regulatory proteins (Rtg1p, Rtg2p, and Rtg3p) of Saccharomyces cerevisiae and Pichia pastoris and identification of P. pastoris RtgXp as a novel regulator of multiple metabolic pathways
Our work demonstrates for the first time that PpRtgXp, a basic, helix-loop-helix (bHLH) protein, is a global regulator of carbon metabolism. PpRtgXp constitutively localizes inside the nucleus. Despite lacking the C-terminal ...
Mechanistic Insights Into Heat Shock Protein 90 (Hsp90) Trans-splicing in Giardia lamblia
Hsp90 gene is conserved and encoded by a single ORF with none to many cis-spliced introns across the biological kingdom. Previous studies from our lab have shown that Hsp90 gene in Giardia lamblia has a split nature having ...
Modeling the CD8+ T cell response to solid tumors: A multi-scale immunoinformatics approach to prognosticating disease outcome
Robust CD8 T cell activity is crucial for anti-tumor immune response. CD8 T cells keep tumors in check using direct effector mechanisms that cause tumor death. The key to this activity is the recognition of tumor cells as ...
Deciphering Hypoxic Adaptations in Cutibacterium acnes using Multi-omics Profiling and Systems Modelling
The opportunistic skin anaerobe Cutibacterium acnes (C. acnes) contributes to skin
homeostasis with its antioxidant and immunomodulatory activities. C. acnes (formerly known as
Propionibacterium acnes) is an aerotolerant, ...
