Investigating DJ-1 homologs in maintaining genome integrity through glycation repair of macromolecules: Implications in regulating mitochondrial health
The current thesis work focuses on DJ-1 superfamily proteins and their role in protection against toxic glycating carbonyls such as Methylglyoxal (MG) and Glyoxal (GO). Our study reveals that yeast DJ-1 homologs (Hsp31 ... -
Hominini-specific regulation of cell cycle by stop codon readthrough of FEM1B
In certain mRNAs ribosomes continue translation beyond the canonical stop codon to generate longer isoform with a C-terminal extension. This phenomenon is termed stop codon readthrough (SCR). Previously, a genome-wide ... -
Role of RTEL1 helicase in the regulation of homologous recombination during DNA replication
Homologous recombination (HR) plays an essential role in the repair of DNA double-strand breaks (DSBs), replication stress responses, and genome maintenance. Although the mechanism of HR has been extensively studied in the ... -
Elucidation of the structure-function relationship of the Saccharomyces cerevisiae HORMA domain-containing proteins Hop1 and Rev7
DNA-based transactions like replication, repair, recombination and transcription are central to survival, inheritance and evolution. Not surprisingly, these mechanisms are tightly regulated by a myriad of protein-protein, ... -
Metabolic and Pharmacological Modulations During IFN-γ signaling
Interferons, initially discovered for their antiviral properties, play pivotal roles in various biological processes, including host defense against pathogens, tumor surveillance, and disease pathogenesis. Interferon-gamma ... -
In vivo mechanistic insights into the trans-splicing based expression of Hsp90 in Giardia lamblia
Giardia lamblia, a simple yet intriguing protozoan parasite, challenges conventional paradigms in gene expression through its unique mechanism of trans-splicing for Heat Shock Protein 90 (Hsp90). As a primitive organism, ... -
Exploring the Marine Algicolous Endophytic Fungi: A Promising Source of Novel Cancer Therapeutics
Cancer is the second leading cause of mortality globally, with over 6 million new cases diagnosed annually. Research on effective therapies is crucial due to the disease's complexity. Natural materials in chemotherapy have ... -
Algorithms for Investigating, Decoding and Designing ligand recognition sites in proteins - A Structural Bioinformatics Approach to Studying Protein Function
All physical processes in living organisms are driven by specific biomolecular interactions. Elucidating the characteristics of biomolecular interactions between proteins and their respective small molecule ligands can ... -
Understanding the role of DNAJC30 and ISCU in mitochondrial homeostasis
Williams-Beuren Syndrome (WBS) is a rare multisystem genomic disorder characterized by mild to moderate cognitive impairment, unique personality traits, distinctive facial features, cardiovascular problems, and infantile ... -
Translation in the 3'Untranslated Region of Mammalian Transcripts
Mammalian mRNAs generally have a 5'UTR (untranslated region), a coding DNA sequence, and a 3'UTR. The 3'UTR of mRNA is generally believed to be the untranslated region of the mRNA. However, there are certain instances ... -
The Nse1p RING domain is required for maintaining transcriptional silencing and genomic organization in Saccharomyces cerevisiae
Chromatin is a dynamic structure that reorganizes to support proper transcription, replication, repair, and segregation. Principal chromosomal constituents that shape chromosomes are the SMC (Structural Maintenance of ... -
Translation in Erythroid cells
Erythrocytes are specialized cells that perform the crucial function of gas exchange in all vertebrates. Regulation of gene expression was believed to be absent in these cells due to the absence of nucleus. It was also ... -
Understanding the adaptive responses of Salmonella Typhimurium during bile stress
Salmonella Typhimurium (S. Typhimurium) is an enteric pathogen that causes gastroenteritis. Although gastroenteritis is usually non-life threatening in healthy adults, it can cause fatality in children and immunocompromised ... -
Deciphering the biochemical and biophysical properties of the Holliday junction resolvases RuvC and RuvX from Mycobacterium smegmatis
Homologous recombination (HR) is a ubiquitous cellular process that occurs in all three domains of life as well as in DNA and RNA viruses. In eukaryotes, HR is critically important for homology-directed DNA repair (HDDR) ... -
Insights into life-cycle stage transition of Trichomonas vaginalis and advancement in its diagnosis
Trichomonas vaginalis is a protozoan parasite and the causative agent of the most common non-viral, sexually transmitted disease (STD) in humans known as trichomoniasis. WHO estimates more than 270 million cases of ... -
A Ligase IV/XRCC4-dependent single strand break repair pathway for the maintenance of A/T-rich regions during DNA replication in mammals
The DNA in our cells is under constant threat from various exogenous and endogenous sources. To ensure error free and faithful transmission of hereditary material, human cells employ several DNA repair pathways. Mammalian ... -
Non-canonical functions of lymphoid-specific proteins AID and RAG1: Understanding mechanism, regulation, and implications in genomic instability
Recombination-activating genes (RAGs) and Activation-induced cytidine deaminase (AID) are lymphoid cell-specific proteins that play crucial roles in the development of adaptive immunity. Diversification of the immune system ... -
Isolation, structure elucidation and increasing anticancer efficacy of an anti-cancer secondary metabolite from a marine-derived endophytic fungus, Aspergillus species
Cancer is the leading cause of mortality globally, contributing to ~10 million fatalities in 2020, or roughly one in every six deaths, according to global cancer statistics 2020. Around 50% of all small molecules approved ... -
Flavivirus RNA replication: Probe development, structural dynamics, and role of zinc ions.
Flaviviruses share a typical genome architecture where the highly conserved UTRs flank a central coding region. They also share a common genome replication strategy called genome cyclization where the UTRs interact to form ... -
Systems biology approach to dissect Salmonella-host interactions
Systems understanding of the biological data is required to capture the complex biochemical information when a pathogen interacts with its host. Such interactions are dynamic and complex, especially because various components ...
