Rational Elicitation of Cold Sensitive Phenotypes
Conditional gene expression and conditional mutants provide a means to modulate the expression of specific genes and to control the activity of their protein products in vivo, so as to be able to study their effects on the ... -
Exploring the Unusual Properties and Non-canonical Roles of Promiscuous Restriction Endonuclease KpnI
Restriction modification (RM) systems are important components of bacterial immune system. Their primary function is to protect the bacteria from invading bacteriophages. Based on the subunit composition, enzyme properties ... -
Plasticity of Intrinsic Excitability in Fast Spiking Interneurons of the Dentate Gyrus & Its Implications for Neuronal Network Dynamics
Inhibitory GABAergic neurons, although forming a minor proportion of the neuronal population in the central nervous system, have been reported to be crucial for different physiological states of the brain. Among the vast ... -
Neural Mechanisms underlying the planning of sequential saccades
Saccades are rapid eye movements that we continually make (about 2-3 times per second) to look around and scan our visual environment. Though we effortlessly execute saccadic eye movements all the time, they are not just ... -
Exploring the Roles of Phase Variable HpyAII Restriction-modification System in the Human Pathogen Helicobacter pylori
Helicobacter pylori is a Gram-negative microaerophilic bacteria known to infect as much as 80% of some populations with an average morbidity range of around 50% of the world population. It has been recognized as a definitive ... -
Functional Insights into the Canonical and Non-canonical Roles of the Fission Yeast Splicing Factor SpPrp16
The spliceosome is a large multi-megadalton RNA-protein machine which facilitates the removal of introns from eukaryotic nascent pre-mRNAs by two concerted transesterification reactions. The spliceosome is comprised of ... -
Delineating the Roles for WNT Signaling During PRRs Driven Inflammatory Responses : Implications for Host-Pathogen Interaction
The mammalian immune system consists of the innate and adaptive arm/s that protect the host against pathogenic infections in a highly coordinated process involving multiple steps. Innate immune cells such as macrophages ... -
Structure- Function Studies on Triosephosphate Isomerase : Some Old Questions, Some New Insights
This thesis describes biophysical, kinetic, structural, and sequence conservation analysis of the glycolytic enzyme triosephosphate isomerase (TIM). TIM catalyses the diffusion limited isomerization of D-glyceraldehyde-3-phospahte ... -
Molecular Genetic Analysis of Trichome Development in Arabidopsis thaliana
Several mutants with aberrant trichome patterning and differentiation are known in Arabidopsis. The genes involved in these processes code for proteins with diverse functions such as transcription, protein degradation, ... -
Salmonella Pathogenesis in Dendritic Cells : Stealthy Approach Against Adaptive Immune Response
Synopsis of work done by Mayuri Gogoi (SR No. 10-09-00-10-31-11-1-08534) for the award of Ph.D. degree in the Faculty of Science, Indian Institute of Science, Bangalore, India. Thesis title: Salmonella pathogenesis in ... -
Host Location in Non-pollinating Fig Wasps of Ficus Racemosa : Age, Oviposition History and the Ovipositor
The fig–fig wasp system is a brood site pollination system where pollinators breed inside an enclosed globular inflorescence (syconium) that they pollinate. This pollination mutualism is subjected to exploitation by the ... -
Notch3 Receptor : Activation Mechanism and Association with Ovarian Cancer
The Notch signaling influences a wide spectrum of cell fate decisions, both during development and in the adult organisms. This pleiotropic role of Notch signaling in humans is attributed partially to the presence of four ... -
Characterization of Thymocyte Subpopulations and Mechanistic Insights during Various Modes of Thymic Atrophy
T lymphocytes along with B lymphocytes constitute the adaptive immune system, which is critical for host defence. The progenitors of T cells arise in the bone marrow and the sequential development of T cells occurs in the ... -
Crystallization and Preliminary Structural Studies on Mycobacterium tuberculosis RuvX
The deadly pathogen Mycobacterium tuberculosis has been characterized for its virulence in immense detail. Regardless of this, the capability of M. tuberculosis to combat extreme stress conditions inside the host cell for ... -
Synergistic Influence of Gene Architecture and Promoter Structure on Transcription in Plants : An in silico Analysis
Understanding the structural organisation of genome and insightful information of gene has helped in exploring the regulation and expression of the gene at a molecular and cellular level. In eukaryotes, the gene regulation ... -
Factors Regulating Cerebellar Granule Neuron Progenitor Proliferation
Cerebella granule neuron progenitors (CGNPs) give rise to a homogenous group of neurons called the cerebellar granule neurons in the developing cerebellum (a hindbrain structure classically associated with fine motor ... -
Uncovering the Role of Mitochondrial Iron-sulfur (Fe-S) Cluster Biogenesis in Human Health and Disease
(2018-09-04)Mitochondrial dysfunction has been implicated for a wide range of human diseases. One of the major biosynthetic processes in human mitochondria is the biogenesis of Iron-Sulfur (Fe-S) clusters which primarily involves in ... -
The Role of DNA Structural Features of Eukaryotic Promoter Sequences in Transcription Regulation
(2018-09-04)Understanding the molecular structure of DNA was considered as greatest achievement in modern biology. It helped in understanding fundamental cellular processes such as replication of DNA, nature of the ... -
DNA Methylation Landscape of Astrocytoma : Role of Fibromodulin (FMOD), a Hypomethylated and Upregulated Gene, in Glioblastoma Cell Migration
(2018-08-30)Astrocytoma is defined as the neoplasia of astrocytes, the most abundant non-neuronal glial cells in brain. According to the WHO classification, the different grades of astrocytoma are- gradeI/pilocytic astrocytoma (benign ... -
