Identification and Characterisation of a miRNA releasing activity from Caenorhabditis elegans
MicroRNAs (miRNA) are endogenous, small non coding RNAs, which play a prominent role in eukaryotic gene regulation. Perturbations leading to an altered abundance of miRNAs can lead to pathological conditions like neurological ... -
Understanding the redox homeostatic mechanisms in Mycobacterium tuberculosis infection
Mycobacterium tuberculosis (Mtb) is an obligate intra-cellular pathogen that causes the disease tuberculosis (TB) in its human hosts. An estimated 1% of the world population is reported to get infected with the disease ... -
Immunological insights into Epidermal Growth Factor Receptor Signaling: Implications for host-pathogen interactions
Infectious diseases account for a large proportion of morbidity and mortality worldwide. The major global efforts lie in effectively enhancing the health span of infected individuals and more importantly, curbing infection ... -
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, ... -
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 ... -
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 ... -
Regulation of Expression of p53 and its Isoform Δ40p53 : Consequences on Cellular Gene Expression
The TP53 tumour suppressor gene encodes for p53 protein which is the frequently altered gene in most of the cancers. p53 protein is activated in response to different stresses and plays major role in maintaining genome ... -
Cellular and Molecular Features of the Response of Mycobacterium smegmatis to Rifampicin and Moxifloxacin Upon Prolonged Exposure
Bacterial persisters are a subpopulation of bacteria that can tolerate lethal concentrations of antibiotics. These are phenotypic variants that can give rise to drug‐susceptible population upon withdrawal of the antibiotic. ... -
Rotavirus Viroplasm Structure (VS) : The First Insights into the Architectural Assembly of the Viral and Host Factors in the VS"
Rotavirus is a major cause of acute gastroenteritis in infants and young children and responsible for approximately 453,000 infantile deaths per year. Rotaviruses are non-enveloped RNA viruses belonging to the Reoviridae ... -
Deciphering the Role of METTL3-Dependent m6A-epitranscriptome in Glioma Stem-like Cells
The major roadblocks in treatment for GBM are resistance to therapy and recurrence of GBM cells. Regardless of various treatment strategies, the average survival of GBM patients is poor and incidence of recurrence remains ... -
Deciphering Functions & Interactions of Fission Yeast Splicing Factor SpSlu7 Relevant to Constitutive & Alternative Splicing
The fission yeast genome with abundant multi-intronic transcripts, degenerate splice signals and presence of alternative splicing machinery is an attractive unicellular fungal model to investigate splice-site recognition ... -
Alternate Fates of tRNAs in Initiation and Elongation
Protein synthesis in all organisms utilizes a special tRNA called the initiator tRNA. Initiator tRNAs take part in the initiation step of protein synthesis by their direct binding to the P‐site of the ribosome. The other ... -
Carbon Starvation Genes Mediate the Cross-talk Between Metabolism and Pathogenesis of Salmonella Typhimurium
Carbon starvation genes mediate the cross-talk between metabolism and pathogenesis of Salmonella Typhimurium Salmonella enterica serovar Typhimurium (S. Typhimurium) can infect a wide range of host animals to cause diseases ... -
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 ... -
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 ... -
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, ... -
