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, ... -
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 ... -
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 ... -
Understanding the Role of Rab22A in Recycling Endosome Biogenesis and Melanocyte Pigmentation
(2018-08-28)Recycling embosoms (REs) are transient intermediates of endosomal network, constantly generated from early/sorting endosomes (EEs/SEs). Conventionally, these organelles function in recycling of many growth/nutrient/signalling ... -
Role of VILAMBIT Genes Controlling Flowering Time and Jasmonic Acid Signaling in Arabidopsis
(2018-08-14)The transition to flowering is an important decision for plants since seed-setting and the survival of the progeny depend on the environmental conditions prevalent during this transition. Therefore, to ensure maximum ... -
Understanding the SNARE Dynamics During Melanosome Biogenesis
(2018-08-11)Melanosome biogenesis is a highly regulated endosomal maturation process wherein structural fibers harbouring immature melanosomes acquires its biosynthetic proteins through the secretory pathway and finally matures into ... -
Role of TCP4 Transcription Factor in the Maturation Program of Arabidopsis Life Cycle
(2018-07-28)TCP4 as an integrator of key developmental events A striking aspect of plant life is their sedentary life-style. Though it relieves them of the obligation of forming a complex body organization, it exposes them to ... -
Mechanism of Recycling of Ribosomes Stalled on mRNAs in Escherichia Coli
(2018-07-28)Studies reported in this thesis address the question of how pre-termination ribosomal complexes stalled during translation of mRNA are recycled. The process of recycling of the stalled ribosomes involves many translational ... -
