Role of Escherichia coli UvrD helicase in resolving G-quadruplex DNA structures
G-quadruplex (G4) secondary structures have been implicated in various biological processes, including gene expression, DNA replication and telomere maintenance. However, unresolved G4 structures impede replication ... -
Role of Glycosylation and Oligomerization on the Stability of Soybean Agglutinin
Carbohydrates are vital to life. In their naive form, they serve as a primary energy source for supporting life. However, in most cases carbohydrates do not exist as simple sugars in nature. Instead they occur as more ... -
Role of Grp 75 Chaperone Folding Machinery in the Maintenance of Mitochondrial Protien Quality Control
(2018-04-03)My research focuses on understanding the importance of human mitochondrial Hsp70 (Grp75) chaperone machinery for the maintenance of protein quality control inside the mitochondrial matrix. The investigations carried out ... -
Role of Hydrogen Sulfide Gas in Modulating HIV-1 Latency and Reactivation
Human Immunodeficiency Virus 1 (HIV-1) remains a global public health threat, claiming 690 thousand people’s lives in 2020 and causing 1.5 million new infections. The advent of combinatorial antiretroviral therapy (ART) ... -
Role Of Idiotypic Anti-Idiotypic Network In The Sustenance Of Immunological Memory
(2009-05-25)Living amidst a milieu of pathogenic organisms, vertebrates are in constant threat of contracting one or the other disease. As a mechanism of protection against such ‘invasions’, the vertebrate immune system has evolved ... -
The Role of Initiation Factor 3 : Insights from E. Coli, Mitochondria and Mycoplasma
(2018-01-07)The process of translation initiation is the most highly regulated step of protein synthesis. In bacteria, three initiation factors (IF1, IF2 and IF3) play crucial roles during initiation. IF3 acts as an anti-association ... -
Role Of Insulin-Like Growth Factors Binding Protien 2 (IGFBP2) In Breast Cancer
(2016-04-27)Insulin-like growth factor binding proteins (IGFBPs) modulate the bioavailability of IGFs in circulation. IGFBPs 1-6 bind IGFs with high affinity and can either potentiate or inhibit IGF signaling in a context dependent ... -
Role of Lactate and TREK1 Channels in Neuroprotection during Cerebral Ischemia – in Vitro Study in Rat Hippocampus
(2017-12-16)Cerebral ischemia is a highly debilitating condition where shortage of oxygen and glucose leads to profuse cell death. Insufficient blood supply to the brain leads to cerebral ischemia and increase in extracellular lactate ... -
Role of Lysyl oxidase in TGF-beta-induced Fibroblast Activation and Cancer-Associated Fibroblast-mediated Breast Cancer Progression
Cancer-associated Fibroblasts (CAFs) are a dominant cell type of the breast cancer microenvironment and are proposed to be involved in metastatic progression. TGF-β has been reported to influence fibroblast to myofibroblast ... -
Role of Mammalian RAD51 Paralogs in Genome Maintenance and Tumor Suppression
(2018-01-28)My research was focused on understanding the importance of mammalian RAD51 paralogs in genome maintenance and suppression of tumorigenesis. The investigation carried out during this study has been addressed toward gaining ... -
Role of mammalian RAD51 paralogs in replication stress response and genome maintenance
The focus of my research has been to understand the molecular mechanisms underlying the role of mammalian RAD51 paralogs in genome maintenance and tumor suppression. The investigation carried out during this study has ... -
Role Of Matrix Protein Of Rinderpest Virus In Viral Morphogenesis
(2008-10-20)Rinderpest virus is an enveloped Nonsegmented Negative Stranded RNA Virus (NNSV) belonging to the genus Morbillivirus in the Family Paramyxoviridae and the causative organism for “cattle plague”. The virion has a transport ... -
Role of Mint family of Proteins in the nanoscale localization and real-time retention of surface Amyloid Precursor
Amyloid beta, a key determinant in the pathology of Alzheimer's disease (AD), is formed by the sequential proteolysis of Amyloid Precursor Protein (APP) by β-and γ-secretase. Evidence over the last few decades indicates ... -
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 ... -
Role of Mycobacterium Tuberculosis RecG Helicase in DNA Repair, Recombination and in Remodelling of Stalled Replication Forks
(2018-05-14)Tuberculosis, caused by the infection with Mycobacterium tuberculosis remained as a major global health challenge with one third of world population being infected by this pathogen. M. tuberculosis can persist for decades ... -
Role of Mycobacterium tuberculosis UvrD1 and UvrD2 helicases in resolving G-quadruplex DNA structures
Unresolved G-quadruplex (G4) DNA secondary structures impede DNA replication and can lead to DNA breaks and to genome instability. Helicases are known to unwind G4 structures and thereby facilitate genome duplication. ... -
The Role of Nursery Size and Plant Phenology on the Reproduction of and Relationships within a Fig-fig Wasp Nursery Pollination System
(2018-05-09)Obligate nursery pollination mutualisms such as the fig–fig wasp system, with their central plant–pollinator mutualism associated with non-pollinating satellite wasp species, can function as closed system microcosms ... -
Role of PdtaS-PdtaR two component signalling system in metabolic adaptation in Mycobacterium spp.
