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 ...
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 ...
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 ...
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, ...
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 ...
Investigating DNA structural basis for fragility during chromosomal translocations associated with human B-cell lymphomas
Genome integrity is essential for normal cellular functions. Erroneous repair of DNA double-strand breaks (DSBs) could lead to chromosomal rearrangements, including chromosomal translocations that may result in altered ...
Host responses in Fas-deficient autoimmune-prone lpr mice upon Salmonella Typhimurium infection
Autoimmune diseases can potentially pre-dispose an individual to infections. On the other hand, infections can trigger, exacerbate or ameliorate autoimmunity. Autoimmune Lymphoproliferative Syndrome (ALPS) is a rare genetic ...
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 ...
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 ...
New insights into the role of condensin in Saccharomyces cerevisiae
Structural Maintenance of Chromosomes (SMC) complexes are highly conserved from prokaryotes to eukaryotes. Saccharomyces cerevisiae has six SMC proteins which form three SMC-complexes in association with non-SMC subunits ...
