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 ... -
Astrocytes regulate oligodendrocyte development and myelination in the mammalian brain
Oligodendrocytes (OLs), a type of glial cell, are the main myelinating cells of the mammalian central nervous system (CNS), enabling efficient saltatory mode of nerve conduction. On the other hand, astrocytes, another glial ... -
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 ... -
Characterization of Visual Stimulus-Induced Gamma Oscillations as Signatures of Mechanisms Underlying Healthy Aging and Disease
Neural oscillations are rhythmic fluctuations in the electrical activity recorded from the brain that convey important information about brain function. Gamma oscillations, which refer to the 30–80 Hz frequency range, are ... -
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 ... -
Conformational Heterogeneity, Solution Structure and Autoregulatory Roles of the MazE9 Antitoxin from Mycobacterium tuberculosis
The work presented in this thesis endeavors to decode the details of the dynamics of MazE9 antitoxin of the Mycobacterium tuberculosis MazEF9 toxin-antitoxin system and the transcriptional autoregulation effected by it. ... -
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) ... -
Deciphering the role of host protein HuR in RNA virus life cycle and pathogenesis: Hepatitis C Virus and SARS-CoV-2 as exemplars.
Viruses pose a major threat to human health and the ongoing SARS-CoV-2 pandemic proves as the best evidence for that. Historically, RNA viruses have a major potential to cause such pandemics. They utilise RNA binding ... -
Decoding of Attention and Behavioral State Using Local Field Potentials
Visual attention has been shown to modulate perceptual behavior and neuronal activity. Early psychophysical studies on attention showed that the subjects detected a target presented at the attended location better (i.e., ... -
Development of patient-derived tumor models toward understanding disease biology and drug screening
Cancer is a complex disease of uncontrolled cell proliferation, which cripples the normal functioning of tissues. According to GLOBOCAN 2020, an estimated 19.3 million new cancer cases and around 10 million cancer deaths ... -
Differential Regulation of Calcium Dependent Phase Separation and Modular Assembly of Sap97/Hdlg Enriched Molecular Complexes
Recent studies over a few decades have changed the perspective of the molecular architecture of functional zones within synapses and other cell junctions. Observations in the last decade confirm Post Synaptic Density as ... -
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 ... -
Elucidating the Role of miR-617 in Oral Squamous Cell Carcinoma Pathogenesis
Oral Squamous Cell Carcinoma (OSCC) or oral cancer is the malignancy of the epithelial lining of the oral cavity. It is the leading cause of cancer-related mortality in Indian males and despite technological advancements, ... -
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 ... -
Establishment of a knock-in mouse model expressing a hypomorphic variant of receptor guanylyl cyclase C
Receptor guanylyl cyclase C (GC-C, gene GUCY2C) is expressed on the apical surface of the intestinal epithelial cells and gets activated by the endogenous ligands guanylin and uroguanylin. Heat-stable enterotoxin (ST) ... -
Evaluation of Cytogenotoxic Potential and Embryotoxicity of KRS Cauvery River Water in Zebrafish (Danio Rerio)
Pollutants and other forms of environmental stress (lifestyle and social behaviour) are of global concern due to significant adverse effects on human health. The term "exposome" has emerged as a concept in environmental ... -
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 ... -
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 ... -
Functional characterisation of splicing factor Slu7 in Cryptococcus neoformans – roles in cell cycle, constitutive and alternate splicing
Fungal genomes, including in pathogenic yeasts like Cryptococcus neoformans (Cnn) and Candida albicans are rich with short introns. 99% of Cryptococcus neoformans genes have introns with an average of 5 introns per gene ... -
Genetic and environmental determinants of swarming in Pseudomonas aeruginosa
Swarming, in bacteria, is a type of group translocation phenomenon observed in several flagellated species characterized by their ability to spread across solid or semi-solid surfaces rapidly – often with a distinct colony ...
