Studies on Δ40p53 mediated regulation of specific coding and non-coding RNAs: Consequences on cellular processes
p53 is a crucial transcriptional regulator which influences almost every possible pathway that impinges on the life of a cell. As expected of such an instrumental protein, the molecular network of p53 is as diverse as it ... -
Understanding cholesterol homeostasis and its impact on GPCR signalling in aging
Full text embargo One year up to July 2024 Aging is defined as the time-related deterioration of physiological functions necessary for survival of organisms. Despite significant progress in the extension of human lifespan ... -
Molecular pathways governing maturation and decay of precursor piRNAs in Caenorhabditis elegans
Piwi-interacting RNAs (piRNAs) are an animal-specific class of germline-enriched small non-coding RNAs that play a crucial role in germline development and fertility in diverse organisms. In Caenorhabditis elegans (C. ... -
Elucidating the role of SNARE Syntaxin 1A in regulating lysosome and melanosome function
SNAREs are transmembrane proteins that localize to specific membranes and facilitate the process of membrane/vesicle fusion. SNAREs mediate the fusion by binding with their respective cognate SNAREs. SNAREs mediate the ... -
Characterization of Neuroprotective Reactive Astrocytes in the Aging Mammalian Brain
The brain manifests cognitive deficits in aging and becomes more vulnerable to neurodegeneration. Astrocytes play several critical roles in the brain, including synapse formation, maturation, elimination, and synaptic ... -
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 ... -
Investigating the role of an atypical dual-specificity phosphatase DUSP28 in mammalian cells
Dual-specificity phosphatases (DUSPs) belong to the protein tyrosine phosphatases (PTP) subfamily and dephosphorylate, both serine/threonine and tyrosine residues of proteins and non-protein substrates. A subgroup of ... -
Structural and functional insights into hybrid AT-less megaenzyme synthase (NRPS) and DNA-MsDps2 complexes using single particle cryo-EM
Microorganisms, mainly bacteria and fungi, are the producers of structurally diverse, complex organic compounds called as secondary metabolites. These metabolites include polyketides (PKs), non-ribosomal peptides (NRPs), ... -
Investigating the role of AMPK in mammary gland alveologenesis and lactation
AMP-activated kinase (AMPK) is an energy sensor that regulates cell growth and metabolism. Reports from our laboratory and others have shown the context-specific role of AMPK signaling in breast cancer. However, its role ... -

Urolithin-A mitigates synaptic dysfunctions associated with epilepsy through VDAC1 inhibition: A novel therapeutic approach
Urolithin-A mitigates synaptic dysfunctions associated with epilepsy through VDAC1 inhibition: A novel therapeutic approach Epilepsies are a group of neurological disorders with a prevalence of 70 million people worldwide ... -
Characterization of XRN2-mediated microRNA turnover mechanism and its pathophysiological significance in eukaryotes
MicroRNAs (miRNAs) are endogenous, small non-coding RNAs that are extensively involved in the posttranscriptional regulation of gene expression in eukaryotes. Comprehensive studies on miRNA expression and function have ... -
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 ... -
Dissecting the function of NuMA in cleavage furrow formation and chromatin decondensation at the mitotic exit in animal cells
In animal cells, the duplicated genetic material is aligned on a microtubule-based structure known as the mitotic spindle during mitosis. At the mitotic exit, the mitotic spindle elongates, and the sister chromatids get ... -
Parietal and prefrontal control of distinct components of attention
In this thesis, we investigate behavioural mechanisms and neural substrates of distinct components of endogenous spatial attention. Endogenous attention facilitates neural processing of the selected stimulus through one ... -
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 ... -
Studies on the promoter specificity determinants and modulators of the prokaryotic transcription machinery
Bacteria adapt to a wide range of environmental conditions by synchronizing transcription with changes in the extracellular environment. This is achieved by the synchronized action of two-component systems, Extra Cytoplasmic ... -
Development of 3D model and understanding translational regulation of breast cancer
Breast cancer is the most common cancer among women in India and worldwide. It is a highly heterogeneous disease caused by several genetic and epigenetic alterations in mammary epithelial cells. Both inter- and intra-patient ... -
Role of Sirt2 in Stress-induced Muscle Atrophy
Skeletal muscle is one of the essential organs in our body, responsible for various functions such as locomotion, transport, protein storage, and thermoregulation. Under certain pathological conditions, there is a reduction ... -
Investigation of anticancer compounds in the natural productome of marine algae associated-endophytic fungi
Cancer is one of the leading causes of death worldwide. Owing to the complex ways in which this disease develops, there is a constant demand for new drugs. Natural products have delivered great promise in inspiring ...
