Transcriptional regulation of a microRNA encoding gene MIR319C during leaf development in Arabidopsis thaliana
The evolutionarily conserved microRNA miR319 and its target transcription factors encoded by five CIN-TCPs (TCP2, 3, 4, 10 & 24) regulate leaf morphogenesis in Arabidopsis by triggering the division to differentiation ... -
Deciphering the mechanisms employed by Salmonella to mediate modulation of host endo-lysosomal machinery
Salmonella genus encompasses Gram-negative, rod-shaped, facultative anaerobic, non-sporulating, and predominantly motile enteric bacteria. It causes pathogenesis in a wide array of hosts, from cold-blooded animals to humans ... -
Post translational modification and DNA binding studies with two nucleoid associated proteins of Mycobacterium tuberculosis
Genome in prokaryotes is found in a small confinement called nucleoid. The nucleoid compaction is brought about by the combined action of topoisomerases and Nucleoid associated proteins (NAPs). Topoisomerases maintain ... -
Decoding Epigenetic Regulators in Cancer: Acetylation of HIF2A by Histone Acetyltransferase 1 (HAT1) is essential for executing hypoxia response in glioma
Gliomas are tumors of the central nervous system arising from glial cells. Based on the origin of the cell type, it can be astrocytoma, oligodendroglioma, and ependymoma. Astrocytoma is the most common type of glioma, ... -
Transcription termination in Mycobacteria
Transcription termination is one of the key events of gene expression that decides the boundary of the gene. Termination either before the stop codon or transcriptional read-through into the downstream gene both have ... -
Unravelling the functional role of Arf-like GTPases 14 and 15 in mammalian cells
Small G-proteins of Arf-like (Arl) GTPase subfamily are shown to regulate several cellular processes including intracellular trafficking, cytoskeletal organization, organelle biogenesis, cell adhesion and migration. Around ... -
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 ...
