Robustness of Neural Activity Dynamics in the Medial Entorhinal Cortex
Biological systems exhibit considerable heterogeneity in their constitutive components and encounter stochasticity across all scales of analysis. Therefore, central questions that span all biological systems are: (a) How ... -
Role of Mint family of Proteins in the nanoscale localization and real-time retention of surface Amyloid Precursor
Amyloid beta, a key determinant in the pathology of Alzheimer's disease (AD), is formed by the sequential proteolysis of Amyloid Precursor Protein (APP) by β-and γ-secretase. Evidence over the last few decades indicates ... -
Solution structures and interaction studies of mycobacterial MazEF6 toxin-antitoxin system
Toxin-Antitoxin (TA) systems are stress response systems found on plasmids and chromosomes of bacteria and archaea. They are involved in important functions such as plasmid maintenance, programmed cell death, persister ... -
Stop codon readthrough of NNAT mRNA and its role in neuronal differentiation
Protein synthesis terminates at the first stop codon encountered by the ribosome. In stop codon readthrough, translation termination is suppressed, enabling the ribosomes to continue translation beyond the canonical stop ... -
Structural and biochemical studies on mycobacterial Uracil-DNA glycosylase (Ung) and MutT1, key proteins involved in maintaining the genomic integrity in Mycobacteria
Maintaining genomic integrity is indispensable for the survival and propagation of an organism. Failure to do so can cause mutations involving structural and functional aberrations, leading to severe diseases. The causative ... -
A study of extracellular matrix dynamics in epithelial cancer progression with a special focus on ovarian cancer spheroidogenesis
Epithelial ovarian cancer (EOC) is one of the most debilitating gynecological cancers in women worldwide due to its insidious symptoms. The predominant subtype of ovarian cancer: high-grade serous ovarian carcinoma (HGSOC), ... -
Substrate interrogation of the CRISPR-Cas12a endonuclease reveals an unexpected functional plasticity
Substrate interrogation of the CRISPR-Cas12a endonuclease reveals an unexpected functional plasticity Currently, Cas9 and Cas12a (also known as Cpf1) are the sole members of a large family of RNA-guided nucleases that ... -
Systems biology approach to dissect Salmonella-host interactions
Systems understanding of the biological data is required to capture the complex biochemical information when a pathogen interacts with its host. Such interactions are dynamic and complex, especially because various components ... -
A systems-level exploration of host responses across the disease spectrum of Tuberculosis and COVID-19
The host immune system orchestrates a defense mechanism against any invading pathogen with a combination of many mechanisms including antibody production, T-cell response, and memory response. The manner and extent of host ... -
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 ... -
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 ... -
Understanding Nonhomologous DNA End Joining: Novel Insights Into Mechanism and Regulation
This study has provided new insights into the mechanistic details of NHEJ and showed that DNA sequence around the break site can be a factor in determining which proteins involved in NHEJ might be recruited with a higher ... -
Understanding the architecture of mitochondrial presequence translocase machinery and its implications in ALS progression
The current thesis describes the structural organization of the presequence translocase machinery and its functional association with ALS pathogenesis. The TIM23 complex is essential for the mitochondrial biogenesis of ... -
Understanding the Long-term Impact and Mechanism of Action of Endosulfan, an Organochlorine Pesticide on Fertility, Development and Growth of Mice
Endosulfan (ES) is one of the major broad-spectrum organochlorine pesticides categorized as Class II (moderately hazardous) by WHO and Class I (highly acutely toxic) by US Environment Protection Agency. Although the use ... -
Understanding the role of mtHsp70 in regulating mitochondrial homeostasis: revealing its significance in Congenital Sideroblastic Anemia progression
Mitochondria are ubiquitous organelles placed at the nexus of several metabolic and signaling pathways essential for cell survival. Therefore, maintaining a healthy and functional organelle becomes paramount for the cell. ... -
Understanding the role of paraspeckle components NEAT1 and PSPC1 in HCV life cycle and pathogenesis
Hepatitis C virus (HCV) is an enveloped, small, icosahedral, positive-sense single-stranded RNA virus that belongs to the Hepacivirus genus and the Flaviviridae family. HCV causes acute and chronic hepatitis which can range ... -
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 ...
