Investigating the Novel Roles of miR-9a and the Regulators of Mitochondrial Dynamics During the Development and Functioning of Indirect Flight Muscles in Drosophila melanogaster
The muscular system is a highly complex and important system in the body. Proper muscle physiology is critical for locomotion, digestion, circulation, reproduction as well as for metabolic and immune homeostasis. Defects ... -
Investigating the role of taxi gene in flight behavior of Drosophila melanogaster
Locomotion is essential for animals and it is regulated by crosstalk between neurons and muscles. Although defects in the crosstalk between neurons and muscles are implicated in many mobility related diseases in human, ... -
Studies on inflammatory responses: Roles of Interferon-gamma in macrophage activation and Nitric oxide synthase 2 during Salmonella Typhimurium infection-induced sepsis
Inflammation is a complex set of immune responses that is critical for survival during injury or infection. It is also crucial for maintenance of tissue homeostasis under myriad conditions caused by cellular stress and ... -
Role of Second (p)ppGpp Synthetase MS_RHII-RSD in Mycobacterium smegmatis
Adaptation to a rapidly fluctuating environment is the key to the survival of an organism. Bacteria sense and respond to stress by an overall reprogramming of the cellular processes to shut down the energy-consuming processes ... -
Role of RNA Polymerase ω Subunit in Metabolism and Stress Response
RNA polymerase (RNAP) is the key enzyme in transcription and it is a multi-subunit enzyme made up of alpha, beta, beta prime and omega subunit in the stoichiometry of α2ββω. Except for the smallest subunit ω (rpoZ), all ... -
Structural Characterization of Biological Macromolecules by Random Conical Tilt Pair Experiments
Structural biology deals with determining the structure of biological macromolecules especially proteins, DNA, RNA. The conformational changes in the structure of a macromolecule helps to decipher its function. This ... -
Understanding the Role of Lsm Domain in Translation Repression Activity of RGG-motif Containing Protein Scd6
Control of gene expression in eukaryotes is regulated at various steps such as transcription, translation and protein degradation. Translation repression of mRNA regulates protein levels and maintains cell homeostasis. ... -
Elucidating Deregulated Novel Pathways in Glioma through Genetic and Epigenetic Approaches
Malignancy of glial cells is termed as glioma. Gliomas comprise of thirty percent of all tumors of the central nervous system (CNS) and eighty percent of malignant brain tumors (Goodenberger and Jenkins, 2012). Astrocytoma, ... -
Structural and Biochemical Studies on Mycobacterial Uracil- DNA N-glycosylase and Mut T1
Maintenance of the genomic integrity of the cell is crucial for the survival and successful propagation of an organism. However, this integrity is under continuous threat from DNA-damaging agents. In addition, errors in ... -
Molecular Insights into the Structure and Function of Pepper Vein Banding Virus Encoded Proteins and Endocytic Uptake Pathway of Virus-like Particles into Mammalian Cells
Viruses are major pathogenic agents that cause a variety of diseases in all living systems. Since their first isolation in 1892 by Dimitrii Ivanovsky, methods of their diagnosis and control, their life cycles, host - virus ... -
Protein Structure and Mutant Phenotype Prediction from Analysis of Mutant Libraries by Deep Sequencing
Proteins play a central role in all the biological processes. The immense diversity in protein structures and functions despite similar underlying composition is intriguing. The work presented in this thesis aims to provide ... -
Exploration of the Recombination Repair Pathway in Mycobacteria : Identification and Characterization of New Proteins
Genomic integrity is a fundamental requisite for survival and proliferation of all organisms. The genetic material is continuously threatened by a multitude of extrinsic and intrinsic factors. Consequently, the presence ... -
Physiological Role of Arr, an ADP-ribosyltransferase in Mycobacterium smegmatis
The studies reported in this thesis address the physiological role of an antibiotic resistance gene arr, followed by establishment of the arr knockout strains (generated during the investigation) for drug testing and ... -
Regulation of Host Innate Immune Responses by Hippo Signaling Pathway during Pattern Recognition Receptors (PRRs) Driven Inflammation : Implication for Host-Pathogen Interactions
Innate immunity refers to the first line of defence system of the host that comes into play immediately or within hours of appearance of invading pathogens like bacteria, viruses and fungi. Cells of the innate immune system ... -
Regulation of Notch signalling by hypoxia and AMPK in breast cancer
Developmental pathways such as Notch are known to regulate self-renewal and cell fate decisions in embryonic and adult tissue-specific stem cells, while deregulation of Notch signalling is associated with malignant ... -
Computational Mechanisms Underlying the Voluntary Control of Reach Movement Planning and Execution
In everyday life we make a variety of reaching movements. Most of these reaching movements have a clear objective of bringing the hand to the spatial location of the object of interest. Although we typically do not explicitly ... -
Wnt/β-Catenin-dependent Epigenetic Factors Shape Host Immune Responses During Mycobacterial Infection
The genus mycobacterium has more than 120 species of bacteria; one being M. tuberculosis (Mtb), the etiological agent of tuberculosis (TB). During infection, the host mounts a heightened immune response to contain the ... -
Structural Studies on Non-toxic Homologues of type II Ribosome Inactivating Proteins (RIPs)
This thesis is concerned with structural and related studies on two non-toxic homologues of type II RIPs. Type II RIPs, which are more toxic than type I, contain an additional lectin chain (B-chain) covalently linked to ... -
Maternal Immune Activation Perturbs Gene Expression in the Embryonic Brain Leading to Autism Spectrum Disorders
Autism Spectrum Disorders (ASD) constitutes a spectrum of developmental disorders that share common phenotypes of social and communication deficits and repetitive behaviours. ASDs have many possible underlying causes ... -
Systematics and Diversification in the Indian Radiation of Hemidactylus Geckos
Understanding the patterns and processes generating biodiversity is fundamental to ecology and evolutionary biology, and studying diversification can give us key insights into this process. In my thesis, I investigate ...
