Nucleoid-associated Proteins of Mycobacterium tuberculosis : Insights into their Functions
Bacteria face the challenging task of compacting their chromosomes to accommodate them in a small cytoplasmic volume and at the same time maintaining the nucleoids in a highly organized and dynamic state for transcription, ... -
Understanding the Regulation of mRNA Translation Repression by RGG-motif Proteins
Messenger RNA translation is one of the most energy expensive steps in the process of gene expression and therefore translation regulation is critical for maintaining cellular homeostasis. In contrast to transcriptional ... -
Ischemic Concentrations of Lactate Increase TREK1 Channel Activity and Expression
TREK1 is a two-pore domain leak potassium channel which contributes to resting membrane potential. TREK1-/- mice exhibit increased neuronal mortality after global ischemia. Neuroprotective agents like volatile anesthetics ... -
Structural and Functional Characterization of Enzymes of Proline Biosynthesis Pathway in Mycobacterium tuberculosis
Tuberculosis is the second largest killer disease on global scale after HIVAIDS. The rapid evolution of Mycobacterium tuberculosis into drug resistant strains and the toxicity of these drugs are the major constraints in ... -
Resource allocation during Flavivirus lifecycle
Single-stranded RNA virus infection cycle progresses by resource (viral RNA) allocation to segregated macromolecular complexes: host ribosomes (translation), viral RNA polymerase (replication) and viral structural proteins ... -
Embryonic Expression of Cytokines: Functional Role of Il-1β During Blastocyst Hatching
The detailed investigation on the embryo-endometrial cytokine expression, in both mouse and hamster, was carried out during the peri-hatching development and it is described in chapter 2. We hypothesize that, for a ... -
Role of SIRT6 in the regulation of mTOR signalling and global protein synthesis
Cells are constantly engaged in the process of making and breaking proteins in a highly organized manner. However, protein synthesis is an energetically expensive process and often competes with other cellular repair and ... -
ROLE OF SIRT6 AND PARP-1 IN MUSCLE HOMEOSTASIS
Sirtuins and PARPs are stress responsive family of proteins regulating genome instability, inflammation, aging-related diseases and energy metabolism. Both sirtuins and PARPs are NAD+ enzymes with deacetylase and ADP-ribose ... -
Malat1 and COP1 mediated host responses orchestrate mycobacterial pathogenesis
Tuberculosis, which is caused by Mycobacterium tuberculosis (Mtb), is viewed to be the predominant cause of death arising due to bacterial infection. Further, the emergence of MDR/XDR strains and co-infections has compounded ... -
Studies on the regulatory roles for Retinoic Acid (RA) during host-microbial interaction : implications for S. aureus and C. albicans infections
Chronic inflammatory disorder is one of the leading causes of death worldwide. Association between pathogenic infection and inflammation governs tissue homeostasis, which relies on extensive crosstalk among signaling ... -
Role of Mycobacterium tuberculosis DinG and UvrD helicases in unwinding G-quadruplex DNA
Recent studies have demonstrated the role of E. coli UvrD as a replicative helicase that facilitates replication of rolling circle plasmids. Along with dinG and rep helicase, UvrD a so-called “accessory helicase” removes ... -
Understanding intramolecular signal transduction in regulated proteases of the High Temperature Requirement A family
Protein homeostasis in all organisms is a complex process involving regulatory mechanisms that govern protein synthesis, post-translational events and degradation. The protein degradation mechanism serves multiple functions ... -
Uncovering the role of NFS1 in Fe-S cluster biogenesis and in the development of Infantile mitochondrial complex II/III deficiency (IMC23D) disease progression and 2. Screening single domain antibody (VHH) against a membrane transporter
The mitochondrion is a double membrane-bound organelle found in all eukaryotic organisms. Mitochondria are endosymbiotic, autogenous organelles referred to as “Powerhouse” of cells due to their ability to synthesize ATP ... -
Initiation of protein synthesis : Role of the three consecutive GC base pairs in the anticodon stem of initiator tRNAs
The presence of the three consecutive GC base pairs in the anticodon stems of the initiator tRNAs (3GC base pairs) are a highly conserved and a vital feature of the initiator tRNAs in all the domains of life. How this ... -
Topoisomerase i from mycobacterium tuberculosis : Dynamics of enzyme function and inhibitor development
Inside the bacterial cell, the genetic material is maintained in a negatively supercoiled state within a compact space. The supercoiling of the genome undergoes topological perturbations during a variety of cellular processes ... -
Spatial and temporal patterns of vegetation- climate interactions
In this thesis, I tried to understand the patterns and processes of vegetation trends at different spatial scales and resolution. The spatial variability in vegetation trends was related to inter and intra-annual changes ... -
Engineering Reverse Turns: Implications in Conformation, Stability and Bioactivity of Peptides and Proteins
The work presented in this thesis provides an overview of the potential role of N-methylation in inducing reverse turns. Backbone N-methylation is one of the common modifications designed by nature and exploited by humans ... -
Probing the Splicing and Enzymatic Function of Fission Yeast Prp16 – A DEAD Box RNA Helicase
Nuclear pre-mRNA splicing occurs at precisely conserved sequence elements at and around the splice sites which result in ligation of exons and release of intron as lariat. The Schizosaccharomyces pombe genome is an apt ... -
Is Spatial Map Shaped by Environmental Determinants?
Humans and other animals form internal mental maps of the outer world in order to navigate. Hippocampal place cells and grid cells in MEC (medial entorhinal cortex) are the key components of this navigation system. However, ...
