Kinetic, Catalytic and Epigenetic Properties of HpyAXVII DNA Methyltransferase – a Phasevarion in the Human Pathogen Helicobacter pylori
Helicobacter pylori is the leading cause of gastric cancer in human beings. It is a helix-shaped, Gram-negative, motile bacteria that colonizes the gastric mucosa and eventually the gastric epithelium. It has an overabundance ... -
Biochemical characterization of UvrD helicase and its 1 interplay with DNA mismatch repair proteins in 2 Neisseria gonorrhoeae
UvrD helicase belongs to type I superfamily of helicases. It participates in Nucleotide Excision Repair (NER) and DNA Mismatch Repair (MMR). It also participates in the rolling circle replication. It has been shown that ... -
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 ... -
Understanding the structural organization of the carrier translocase machinery in regulating mitochondrial biogenesis and organelle quality control
Mitochondria are essential eukaryotic organelles required for diverse cellular functions including, energy homeostasis, iron-sulfur cluster biogenesis, and signaling. Therefore, the maintenance of organelle quality control ... -
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 ... -
Determination of significance of SUMOylation of the Smc5/6 complex
The fascination of scientists to the Smc5/6 complex began in the 1990s, with the characterization of UV and γ radiation-sensitive rad18 mutant and its identification as a component of a novel Structural Maintenance of ... -
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 ... -
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 ... -
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, ... -
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 ... -
A molecular systems approach to unravel mechanisms and targets in antifolate-resistant bacteria and cancers
Antifolates such as trimethoprim (TMP) and methotrexate (MTX) widely used for treating bacterial infections and certain cancers respectively, inhibit dihydrofolate reductase (DHFR) in the folate pathway. However, the use ... -
Towards precision medicine to detect, characterize and treat liver cancer: Large-scale data analyses using genome-wide networks
In summary, various systems biology approaches were applied to identify a potential genesignature set to monitor CLD progression which can help in the early detection of HCC. An unbiased analysis of metabolic alterations ... -
Characterization of mouse Apolipoprotein L9 and investigation of its cellular functions
This thesis is divided into 3 chapters. Chapter 1, titled General Introduction, is a chapter that familiarizes the reader with the general subject matter of the thesis so that the content of Chapters 2 and 3 can ... -
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 ... -
Mapping the Functional Domain of Glycodelin A : An Immunomodulatory Lipocalin
Glycodelins (Gds) are dimeric, glycosylated proteins belonging to the lipocalin superfamily which are primarily transporters of small hydrophobic molecules. Gd is classified under the lipocalin superfamily as it shows 55 ... -
Oleosin, a Bifunctional Enzyme is Phosphoregulated by a Protein Kinase
In eukaryotic cells, lipids are indispensable principal components that vitiate biological life. Lipids are classified into two major groups, polar and non-polar lipids. Polar lipids are phospholipids, whereas non-polar ... -
Understanding the Regulation of mRNA Translation Repression by RGG-motif Proteins
Messenger RNA translation is one of the most energy expensive steps in the process of gene expression and therefore translation regulation is critical for maintaining cellular homeostasis. In contrast to transcriptional ... -
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 ...
