Role of the unstructured N-terminal region and interacting proteins on the function of Mycobacterium tuberculosis σA
A distinctive feature of the bacterial RNA polymerase is the modular organization. The core of this enzyme, comprised of a dimer of the α subunit assembles with the β, β', and ω subunit. The core RNA polymerase enzyme ... -
Astroglial development as the basis for the effects of early life stress on adult depressive-like behavior
This thesis investigates the enduring effects of early-life stress, specifically maternal separation, on astroglial population and the subsequent behavioral outcomes in adult mice. While the persistent impact of early-life ... -
Understanding protein structural excursions using residue networks and implications on biological function
The information required for a protein structure to fold into the native conformation is encoded in its sequence. Studying protein structures help to understand their biological function. Molecular interactions between ... -
Venomics of Medically Important yet Neglected Elapid Snakes of India and the Antivenomic Potential of Plant Extracts
India is considered the world's snakebite capital, where over 58,000 snakebite fatalities are registered annually. Most bites are primarily attributed to four snake species: the spectacled cobra (Naja naja), common krait ... -
Understanding the interaction mechanism of bacterial virulence factors and effector proteins with host lipid membrane using single particle cryo-electron microscopy
Pathogenic bacteria employ an array of biological macromolecules and cellular structures that help in the initiation and progression of disease in host organism. These ‘virulence factors’ can either be secreted by the ... -
Role of Sirtuin 2 in the development of tissue fibrosis
Wound healing is a crucial physiological process required for the healthy lifespan of an organism. Dysregulation in the process of wound healing leads to the production of excess extracellular matrix leading to fibrosis. ... -
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, ... -
Investigating mechanisms underlying astrocytic involvement in depressive-like behavior and antidepressant action
Major Depressive disorder (MDD) is a complex, multifactorial psychiatric illness which affects over 20% of the population worldwide. Despite its prevalence, our understanding of its pathophysiology is severely limited, ... -
Solution NMR studies of a potent subtilisin inhibitor from Budgett’s frog and the catalytic subunit of AHAS
This thesis involves a detailed structural study of two molecular systems, a small disulfide-rich peptide LL-TIL and a large catalytic subunit of AHAS. Subtilisin inhibitors play an important role in fighting against ... -
Understanding structure, function, and dynamics in macromolecular complexes
In the scope of my thesis work, a concerted effort was undertaken to elucidate bi- ological functions through the lens of structural analysis, employing protein dy- namics. The role of protein dynamics in shaping and ... -
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 ... -
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. ... -
Risks of finding mates in the wild: Ecological and Behavioural Determinants of Sex-biased Predation
Sex-biased predation occurs when one sex of a prey species is consumed more than the other, irrespective of their relative availability (sex-ratio). Some of the potential factors leading to sex- biased predation are sex ... -
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., ... -
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 ... -
On mechanisms and conformational dynamics of Drug:H+ Antiporters
Multidrug efflux is an active transport process involving energy consumption to drive antibacterial compounds out of cells. This is performed either through primary active transport, where chemical energy, such as hydrolysis ... -
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 ...
