Conservation and divergence of the nucleotide excision repair pathway: Comparison of UvrB and UvrC proteins from Mycobacterium tuberculosis and Escherichia coli reveal significant differences in their functional properties
This thesis is presented in three chapters divided by topics. Chapter I will begin with an overview of literature regarding different types of DNA damage, DNA repair pathways in bacteria, properties of E. coli UvrABC ... -
Development and Characterization of a potent Tumor Necrosis Factor-alpha blocking agent
Tumor necrosis factor-α (TNFα), one of the major pro-inflammatory cytokines, plays a pivotal role in an effective inflammation process and immune response. TNFα interacts with two different receptors, TNFR1 and TNFR2, which ... -
Establishment of human ectopic liver tissue in immunocompromised mice as a model for Hepatitis C Virus studies
Infection with hepatitis C virus (HCV) leads to an inflammatory condition which may progress to liver cirrhosis and in some cases, hepato-cellular carcinoma. Though, new drugs are being added to the list of HCV therapeutics, ... -
Functional characterization of Salmonella Typhimurium encoded Cold Shock Protein E during stress responses, biofilm formation and virulence
Overall, this study reports novel functional roles of S. Typhimurium encoded CspE during bile resistance, biofilm formation and in vivo virulence. It also establishes importance of an uncharacterised protein YciF, implicating ... -
Insights into the Differential Cytotoxicity of Abrin and Design of a Vaccine Candidate against the Toxin
Ribosome inactivating proteins (RIPs) from plants, fungi or bacteria are extremely lethal due to their N-glycosidase activity on eukaryotic ribosomal RNA. As the name indicates, these toxins inactivate ribosomes; thereby ... -
Mechanistic insights into the replication of Sesbania mosaic virus
The present thesis deals with the mechanism of replication of Sesbania mosaic virus (SeMV), which belongs to the genus sobemoviruses. Sobemoviruses are single stranded positive sense RNA viruses which infect both mono and ... -
A molecular systems approach to unravel mechanisms and targets in antifolate-resistant bacteria and cancers
Antifolates such as trimethoprim (TMP) and methotrexate (MTX) widely used for treating bacterial infections and certain cancers respectively, inhibit dihydrofolate reductase (DHFR) in the folate pathway. However, the use ... -
New insights into the role of condensin in Saccharomyces cerevisiae
Structural Maintenance of Chromosomes (SMC) complexes are highly conserved from prokaryotes to eukaryotes. Saccharomyces cerevisiae has six SMC proteins which form three SMC-complexes in association with non-SMC subunits ... -
Production of taxol from Lasiodiplodia theobromae and biochemical characterization of its 10-deacetylbaccatin III-10-O-acetyltransferase enzyme and evaluation of anticancer activity of enzymatically synthesized baccatin III
Taxol (paclitaxel) originally identified from the inner bark of Taxus brevifolia, is a clinically approved anticancer drug for the treatment of various kinds of cancer, particularly ovarian cancer, breast cancer and Kaposi's ... -
Regulation of RecA nucleoprotein filament stability by RecX and the effects of RecA-membrane interaction on the activities of RecA in mycobacteria
E. coli RecA is a multifunctional protein known to be associated with the cell membrane, forming foci often located at the cell poles, which gets redistributed along the length of the cell during SOS response. Several lines ... -
A role for the cohesin complex in subtelomeric gene silencing in Saccharomyces cerevisiae
Chromatin is a dynamic structure which reorganizes to support numerous chromosomal processes. Various histone and non-histone proteins are involved in chromatin organization. One such group of non-histone proteins, known ... -
Role of Mycobacterium tuberculosis DinG and UvrD helicases in unwinding G-quadruplex DNA
Recent studies have demonstrated the role of E. coli UvrD as a replicative helicase that facilitates replication of rolling circle plasmids. Along with dinG and rep helicase, UvrD a so-called “accessory helicase” removes ... -
Studies on inflammatory responses: Roles of Interferon-gamma in macrophage activation and Nitric oxide synthase 2 during Salmonella Typhimurium infection-induced sepsis
Inflammation is a complex set of immune responses that is critical for survival during injury or infection. It is also crucial for maintenance of tissue homeostasis under myriad conditions caused by cellular stress and ... -
Towards precision medicine to detect, characterize and treat liver cancer: Large-scale data analyses using genome-wide networks
In summary, various systems biology approaches were applied to identify a potential genesignature set to monitor CLD progression which can help in the early detection of HCC. An unbiased analysis of metabolic alterations ... -
Uncovering the role of NFS1 in Fe-S cluster biogenesis and in the development of Infantile mitochondrial complex II/III deficiency (IMC23D) disease progression and 2. Screening single domain antibody (VHH) against a membrane transporter
The mitochondrion is a double membrane-bound organelle found in all eukaryotic organisms. Mitochondria are endosymbiotic, autogenous organelles referred to as “Powerhouse” of cells due to their ability to synthesize ATP ... -
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 ...
