Biochemical characterization of UvrD helicase and its 1 interplay with DNA mismatch repair proteins in 2 Neisseria gonorrhoeae
UvrD helicase belongs to type I superfamily of helicases. It participates in Nucleotide Excision Repair (NER) and DNA Mismatch Repair (MMR). It also participates in the rolling circle replication. It has been shown that ... -
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 ... -
Deciphering Hypoxic Adaptations in Cutibacterium acnes using Multi-omics Profiling and Systems Modelling
The opportunistic skin anaerobe Cutibacterium acnes (C. acnes) contributes to skin homeostasis with its antioxidant and immunomodulatory activities. C. acnes (formerly known as Propionibacterium acnes) is an aerotolerant, ... -
Deciphering the biochemical and biophysical properties of the Holliday junction resolvases RuvC and RuvX from Mycobacterium smegmatis
Homologous recombination (HR) is a ubiquitous cellular process that occurs in all three domains of life as well as in DNA and RNA viruses. In eukaryotes, HR is critically important for homology-directed DNA repair (HDDR) ... -
Deciphering the role of DJ-1 homologs in alleviating carbonyl and oxidative stress in Arabidopsis thaliana
The present study aims to elucidate the physiological role of plant DJ-1 homologs in Arabidopsis thaliana under various abiotic stress conditions. It seeks to provide deeper insights into the diverse functions of plant ... -
Determination of significance of SUMOylation of the Smc5/6 complex
The fascination of scientists to the Smc5/6 complex began in the 1990s, with the characterization of UV and γ radiation-sensitive rad18 mutant and its identification as a component of a novel Structural Maintenance of ... -
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 ... -
The dual-targeting of Saccharomyces cerevisiae Pso2 into the nucleus and mitochondria is regulated by post-translational modifications: Implications for organelle-specific DNA repair
The repair of DNA interstrand crosslinks (ICLs) involves the concerted action of multiple DNA repair pathways. In eukaryotes, ICLs are sensed and repaired by replication-coupled or replication-independent mechanisms in ... -
Elucidating the diverse functions of RGG-motif containing proteins
One year embargo upto 20/2/2026 RGG-motif containing proteins represent one of the major subsets of RNA-binding proteins characterized by the presence of RGG/RG repeats. These proteins have been associated with a wide ... -
Elucidation of the structure-function relationship of the Saccharomyces cerevisiae HORMA domain-containing proteins Hop1 and Rev7
DNA-based transactions like replication, repair, recombination and transcription are central to survival, inheritance and evolution. Not surprisingly, these mechanisms are tightly regulated by a myriad of protein-protein, ... -
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, ... -
Exploring the Marine Algicolous Endophytic Fungi: A Promising Source of Novel Cancer Therapeutics
Cancer is the second leading cause of mortality globally, with over 6 million new cases diagnosed annually. Research on effective therapies is crucial due to the disease's complexity. Natural materials in chemotherapy have ... -
Exploring the role of low complexity protein sequence in regulating RNA granule dynamics and translation control
RNA granules are conserved membraneless mRNP complexes that play an important role in determining mRNA fate by affecting translation repression and mRNA decay. Processing bodies (P-bodies) harbor enzymes responsible for ... -
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 ... -
Hominini-specific regulation of cell cycle by stop codon readthrough of FEM1B
In certain mRNAs ribosomes continue translation beyond the canonical stop codon to generate longer isoform with a C-terminal extension. This phenomenon is termed stop codon readthrough (SCR). Previously, a genome-wide ... -
Identification and Biochemical Characterization of Novel Inhibitors of Nonhomologous End Joining: Implications in DNA Double-Strand Break Repair and Cancer Therapy
To summarize, in the present study, we have synthesized and characterized three novel NHEJ inhibitors targeting DNA Ligase IV, with several fold better efficacy compared to SCR7 and thus potential to be developed as cancer ... -
In vivo mechanistic insights into the trans-splicing based expression of Hsp90 in Giardia lamblia
Giardia lamblia, a simple yet intriguing protozoan parasite, challenges conventional paradigms in gene expression through its unique mechanism of trans-splicing for Heat Shock Protein 90 (Hsp90). As a primitive organism, ... -
Insights into life-cycle stage transition of Trichomonas vaginalis and advancement in its diagnosis
Trichomonas vaginalis is a protozoan parasite and the causative agent of the most common non-viral, sexually transmitted disease (STD) in humans known as trichomoniasis. WHO estimates more than 270 million cases of ... -
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 ... -
