Understanding the Mechanism of Double-strand Break Repair and Genome Fragility in Mammalian Mitochondria
Mitochondria are semiautonomous organelles in a cell as they have their own genome that replicates independently. It plays a major role in oxidative phosphorylation due to which mitochondrial DNA (mtDNA) is frequently ... -
Understanding the Mechanism of Homologous Recombination in Mycobacterium Tuberculosis : Exploring RecA as an Antibacterial Target and Characterization of Holliday Junction Resolvases
(2018-08-09)Homologous recombination (HR) is conserved across all three domains of life and is associated with a number of key biological processes. Over the years, numerous genetic, biochemical and structural studies have uncovered ... -
Understanding the Mechanism of Noncanonical Functions of RAGs in Lymphoid Cancer and Glioblastoma
Recombination activating genes (RAGs) composed of RAG1 and RAG2, are the endonuclease involved in V(D)J recombination, which is critical for adaptive immunity in mammals. Activation-induced cytidine deaminase (AID), expressed ... -
Understanding the Regulation of mRNA Translation Repression by RGG-motif Proteins
Messenger RNA translation is one of the most energy expensive steps in the process of gene expression and therefore translation regulation is critical for maintaining cellular homeostasis. In contrast to transcriptional ... -
Understanding the Role of Lsm Domain in Translation Repression Activity of RGG-motif Containing Protein Scd6
Control of gene expression in eukaryotes is regulated at various steps such as transcription, translation and protein degradation. Translation repression of mRNA regulates protein levels and maintains cell homeostasis. ... -
Understanding the Role of ThiJ/DJ-1/PfpI Family Member Proteins in Regulating Redox Homeostasis, Mitochondrial Health and Lifespan in Saccharomyces cerevisiae
In a healthy cell, the ROS levels are stringently regulated by the action of various enzymatic or non-enzymatic antioxidant systems. Imbalance in the ROS homeostasis generates oxidative stress resulting in damage to cellular ... -
Understanding the Sequence Dependence of NHEJ Mediated Double-strand Break Repair, and Identification of Novel DNA Ligase Inhibitors and their Potential Use as Cancer Therapeutics
Repair of DNA breaks is essential for maintenance of genomic integrity. DNA double-strand breaks (DSBs) are considered as the most harmful DNA lesions within the cells which if left unrepaired or are misrepaired, can lead ... -
Understanding the structural organization of the carrier translocase machinery in regulating mitochondrial biogenesis and organelle quality control
Mitochondria are essential eukaryotic organelles required for diverse cellular functions including, energy homeostasis, iron-sulfur cluster biogenesis, and signaling. Therefore, the maintenance of organelle quality control ... -
Unfolded Protein Response in Malaria Parasite
(2018-01-28)Plasmodium falciparum is responsible for the most virulent form of human malaria. The biology of the intra-erythrocytic stage of P. falciparum is the most well studied as it is this stage that marks the clinical manifestation ... -
Unique Features Of Heme-Biosynthetic Pathway In The Human Malaria Parasite, Plasmodium Falciparum
(2010-12-29)Malaria is a life-threatening vector borne infectious disease caused by protozoan parasites of the genus Plasmodium. More than 100 species of Plasmodium can infect numerous animal species such as reptiles, birds and various ... -
Unraveling the Intricate Architecture of Human Mitochondrial Presequence Translocase - Insights on its Evolution and Role in Tumourigenesis
(2018-04-23)The present thesis focuses on the elucidation of human mitochondrial inner membrane presequence-translocation machinery with implications on cancer cell proliferation. Mitochondria are the endosymbiotic organelles in an ... -
Untangling the Helicobacter pylori genome: Deciphering the significance of zinc finger motif(s) in Topoisomerase I catalysis
Helicobacter pylori, a human pathogen dominating gastric microbial population, displays differential gene expression during various stages of stomach colonization. Topoisomerases play a crucial role in maintaining DNA ... -
Virus-Inducible Gene Expression Changes In Mouse Brain : Studies With Japanese Encephalitis & Rabies Viruses
(2009-04-16)One of the key events in a virus-infected host cell is the activation and repression of a large number of host genes. In recent years, such differentially expressed host genes have been identified for several viruses, ...
