Protein-small molecule interactions: Structural insights and applications in computational drug discovery
Deviation from normal healthy conditions, termed as disease, can often be triggered due to the malfunctioning of proteins. Modulating the functions of proteins by administering therapeutic agents (drugs) may alleviate the ... -
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 ... -
Use of Human Induced Pluripotent Stem Cells as a Model to Study Primary Microcephaly
The aim of this study was to use human induced pluripotent stem cells (hiPSC) to understand key steps of neuronal differentiation and to model the human brain developmental disorder, primary microcephaly (MCPH). MCPH is a ... -
Understanding the regulation of translation and replication of Coxsackievirus B3 RNA by host RNA binding proteins
Coxsackievirus B3 (CVB3) is an enterovirus, with a positive-sense single-stranded RNA genome. The genome contains a single open reading frame (ORF) flanked by untranslated regions (UTR) at the 5’ and 3’ ends. The viral ... -
Conservation and divergence of the nucleotide excision repair pathway: Comparison of UvrB and UvrC proteins from Mycobacterium tuberculosis and Escherichia coli reveal significant differences in their functional properties
This thesis is presented in three chapters divided by topics. Chapter I will begin with an overview of literature regarding different types of DNA damage, DNA repair pathways in bacteria, properties of E. coli UvrABC ... -
Development and Characterization of a potent Tumor Necrosis Factor-alpha blocking agent
Tumor necrosis factor-α (TNFα), one of the major pro-inflammatory cytokines, plays a pivotal role in an effective inflammation process and immune response. TNFα interacts with two different receptors, TNFR1 and TNFR2, which ... -
Roles of N10-formyl-tetrahydrofolate (N10-fTHF), ribosomal large subunit pseudouridine synthase D (RluD), and transcription-translation coupling in the fidelity of translation initiation in Escherichia coli
Protein synthesis is a fundamental process in gene expression. It involves four basic steps – initiation, elongation, termination, and ribosome recycling in bacteria. However, the step of initiation is the most regulated ... -
Biochemical and functional characterization of the enigmatic MPPED1/MPPED2 metallophosphodiesterases
Evolutionarily conserved genes in nature have been known to perform critical functions inside the cell. Earlier bioinformatic analysis performed in our laboratory identified mammalian orthologs of Rv0805, a novel class III ... -
Biochemical and Functional Characterization of the Mycobacterial PdtaS-PdtaR Two Component System
Two-Component Systems (TCSs) are primarily prokaryotic modes of cell signaling involving a receptor sensor kinase (SK) that senses stimuli and a response regulator (RR) that effects a response, usually at the level of ... -
Local Interactions, Spatial Patterns and Ecosystem Stability
Many ecosystems exhibit striking patterns in the spatial distribution of organisms, for example, patterns of clumping and dispersion in semi-arid vegetation, mussel in intertidal beds and even sea-grass and macroalgae. ... -
Influence of the substrate specificity of Mycobacterium tuberculosis ClpX on the transcriptional profile
Cellular homeostasis in bacteria is maintained by diverse molecular machines. These include several one-component systems (OCS), two- component systems (TCS), chaperone proteins, proteases, proteolytic complexes and ... -
Functional Characterization of a SAND–Domain–containing Factor OsULTRAPETALA1 – a Direct Downstream Target of OsMADS1
Studies on meristem identity regulators in Rice (Oryza sativa), a model plant for cereal crops have revealed how meristem identity and transitions are controlled, bearing implications for crop yield improvement. We were ... -
Molecular insights into AMP-activated protein kinase (AMPK)-mediated regulation of anoikis resistance
Our study identifies negative cross-talk between AMPK and two important cellular kinases, Akt and Erk. AMPK-mediated inhibition of these two kinases promotes survival of cancer cells in the matrix-deprived condition. ... -
Stimulus statistics and HCN current mediated resonance sets the scale of input-output mapping in Stellate cells of the Medial Entorhinal Cortex
The functional significance of the computations performed by Stellate cells of the Medial Entorhinal Cortex, proven time and again, makes them insightful, yet intriguing. The gradients of the intrinsic properties of these ... -
Regulation of auxin response by UBIQUITIN-SPECIFIC PROTEASE14/ TARANI in Arabidopsis thaliana
The genetic pathway regulating auxin response in Arabidopsis is well established and provides us a framework to assess whether TNI belongs to this pathway. The total number of lateral roots is taken as a read-out of auxin ... -
Influence of Tgf-B on Mechanobiology of Human Breast Cancer Cells
Breast cancers are characterized by extensive modifications to mechanical properties of the tissue via increased ECM production and vascularization. TGF-B is a multi-functional cytokine that is implicated in cancer invasion ... -
Understanding the Role of SIRT2 in Cardiac Hypertrophy, Cell Death and Glucose Homeostasis
Over the last century the major causes of human deaths and ailments has shifted from acute infectious diseases to chronic aging related disorders like cancer and type-2 diabetes. The aging process is a universal property ... -
Dissecting the role of Ataxin 2 Binding Protein 1 in sarcomeric protein stoichiometry and generation of muscle diversity in Drosophila melanogaster
Drosophila muscles are an excellent model to study muscle development, diversity and function. Drosophila muscles consist of two major types –1. Indirect Flight Muscles (IFM), that are fibrillar; as opposed to other tubular ... -
