Immunological consequences of host signaling-regulated epigenetic modification(s) during mycobacterial pathogenesis
Introduction: Mycobacterium tuberculosis (Mtb), the principal etiological agent of pulmonary tuberculosis (TB), continues to co-evolve with the human population making itself one of the most potent infectious killer in the ... -
Characterization of the transsulfuration enzyme Cystathionine beta-synthase as a novel regulatory node in the sulfur metabolism of Mycobacterium tuberculosis
Methionine and cysteine metabolisms are important for the survival and pathogenesis of Mycobacterium tuberculosis (Mtb). The transsulfuration pathway converts methionine to cysteine and represents an important link between ... -
Studies on exosomal microRNAs and proteins associated with Hepatitis C and Dengue virus induced pathogenesis
Studies on the exosomal microRNAs and proteins associated with Hepatitis C and Dengue virus-induced pathogenesis. Hepatitis C virus and Dengue virus are the group of positive-strand RNA viruses belonging to the family ... -
Manipulating Bacterial and Host Reactive Oxygen Species (ROS)- based mechanisms to potentiate killing of Mycobacterium tuberculosis (Mtb)
Mycobacterium tuberculosis (Mtb) is evolutionarily equipped to resist exogenous reactive oxygen species but shows vulnerability to an increase in endogenous ROS (eROS). Since eROS is an unavoidable consequence of aerobic ... -
Role of Hydrogen Sulfide Gas in Modulating HIV-1 Latency and Reactivation
Human Immunodeficiency Virus 1 (HIV-1) remains a global public health threat, claiming 690 thousand people’s lives in 2020 and causing 1.5 million new infections. The advent of combinatorial antiretroviral therapy (ART) ... -
Mechanism of the Development of Genetic Resistance to Antibiotics Mediated by three Reactive Oxygen Species in Mycobacterium smegmatis
Bacteria use different means to survive in the continued presence of antibiotics. We find that upon prolonged exposure to antibiotics, mycobacteria put up a triphasic response comprised of a logarithmic reduction of the ... -
Understanding the regulation of translation and replication of Coxsackievirus B3 RNA by host RNA binding proteins
Coxsackievirus B3 (CVB3) is an enterovirus, with a positive-sense single-stranded RNA genome. The genome contains a single open reading frame (ORF) flanked by untranslated regions (UTR) at the 5’ and 3’ ends. The viral ... -
Roles of N10-formyl-tetrahydrofolate (N10-fTHF), ribosomal large subunit pseudouridine synthase D (RluD), and transcription-translation coupling in the fidelity of translation initiation in Escherichia coli
Protein synthesis is a fundamental process in gene expression. It involves four basic steps – initiation, elongation, termination, and ribosome recycling in bacteria. However, the step of initiation is the most regulated ... -
Functional Characterization of a SAND–Domain–containing Factor OsULTRAPETALA1 – a Direct Downstream Target of OsMADS1
Studies on meristem identity regulators in Rice (Oryza sativa), a model plant for cereal crops have revealed how meristem identity and transitions are controlled, bearing implications for crop yield improvement. We were ... -
Regulation of auxin response by UBIQUITIN-SPECIFIC PROTEASE14/ TARANI in Arabidopsis thaliana
The genetic pathway regulating auxin response in Arabidopsis is well established and provides us a framework to assess whether TNI belongs to this pathway. The total number of lateral roots is taken as a read-out of auxin ... -
Understanding the Role of SIRT2 in Cardiac Hypertrophy, Cell Death and Glucose Homeostasis
Over the last century the major causes of human deaths and ailments has shifted from acute infectious diseases to chronic aging related disorders like cancer and type-2 diabetes. The aging process is a universal property ... -
Studies on Nudix hydrolase proteins and crosstalk between DNA repair pathways
Mycobacterium tuberculosis, the causative agent of tuberculosis, has become a global health concern. This calls for a dire need to understand various aspects of mycobacterial physiology in order to design better strategies ... -
Improving Glioblastoma Management: A Study of Biomarkers, Tumor Microenvironment and Chemoresistance
Glioblastoma (GBM) is an aggressive form of adult brain tumors. The current standard of care includes maximal safe resection followed by concurrent chemo-radiation therapy and adjuvant chemotherapy with temozolomide. ... -
Altering DNA topology in mycobacteria: impact of perturbation of DNA gyrase on physiology and gene expression
In the current dissertation, efforts have been made to probe the in vivo role of DNA gyrase to determine its importance in the growth, physiology and gene expression in mycobacteria. In this dissertation, the role of DNA ... -
Biochemical, Genetic and Molecular characterization of TCP3 and TCP4 transcription factors in Arabidopsis thaliana
The TEOSINTE BRANCHED1, CYCLOIDEA, PROLIFERATING CELL FACTORs (TCP) family of proteins consists of plant-specific, non-canonical basic helix-loop-helix transcription factors that perform diverse developmental processes. ... -
Role of conserved features of initiator tRNA and ribosome heterogeneity in translation initiation in Escherichia coli
Translation is one of the fundamental and core cellular processes catalysed by a ribonucleoprotein complex called ribosome. The process involves four major steps: initiation, elongation, termination and recycling. Initiation ... -
Role of TCP transcription factors in seedling development, leaf morphogenesis and senescence in Arabidopsis thaliana
The TCP gene family encodes non-canonical bHLH transcription factors that act as key regulatory molecules in diverse developmental processes in plants including organ morphogenesis, plant architecture, leaf maturation, and ... -
Genetics of Glioblastoma: Insights into Biology and Therapy Resistance
The central nervous system contains the neural stem cells which differentiate and give rise to the neurons as well as the glial cells which are non-neuronal in nature and provide support and protection to neurons. Unlike ... -
Regulation of Hepatitis C Virus life-cycle by lncRNA HULC: crosstalk with other host factors
Hepatitis C virus (HCV) is a positive sense single-stranded RNA virus. It belongs to the family Flaviviridae and the genus hepacivirus. Following the receptor-mediated endocytosis, HCV genome is released into the cytoplasm, ... -
Functional characterization of a new enzymatic activity of the ‘miRNase’-XRN-2 from Caenorhabditis elegans.
Ribonucleic acid (RNA) molecules play a central role in every pivotal process in the cell, and ribonucleases (RNases) are critical for their biogenesis, processing, and degradation. Therefore, RNases are indispensable for ...
