Investigation of anticancer compounds in the natural productome of marine algae associated-endophytic fungi
Cancer is one of the leading causes of death worldwide. Owing to the complex ways in which this disease develops, there is a constant demand for new drugs. Natural products have delivered great promise in inspiring ... -
Metabolic Regulation of Gametocytogenesis in Malaria
Plasmodium sp. is an obligate intracellular protozoan parasite causing malaria and is responsible for more than 500,000 human deaths annually. P. falciparum and P. vivax are the two major species causing malaria in humans. ... -
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 ... -
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 ... -
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. ... -
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 ... -
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 ... -
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 ... -
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 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 ... -
Studies on the roles of rffG and rfbB encoding dTDP-glucose 4,6- dehydratase in Salmonella Typhimurium
Salmonellosis is a major health concern which causes significant morbidity and mortality worldwide. Infection with Salmonella Typhimurium leads to self-limiting diarrhea in healthy individuals and invasive disease in ... -
Roles of Protein Acetylation in the Human Pathogen Helicobacter pylori
Helicobacter pylori is a gram-negative epsilon proteobacterium infecting half of the world population. H. pylori is a naturally competent bacterium with a huge repertoire of Restriction-Modification (RM) systems. The ... -
Regulation of Flagellar Motility in Giardia lamblia and Trichomonas vaginalis
Protozoan pathogens are responsible for infections that are highly prevalent, especially in developing and under-developed countries. Flagellar motility is exhibited by a variety of organisms ranging from bacteria to certain ... -
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 ... -
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 ... -
Regulation of carbon metabolism in Pichia pastoris by Mxr1p and identification of novel regulators
Pichia pastoris (a.k.a. Komagataella phaffii), a widely used yeast for recombinant protein production, is cultured under a variety of conditions ranging from shake flasks to large bioreactors employing minimal, chemically ... -
Role of mammalian RAD51 paralogs in replication stress response and genome maintenance
The focus of my research has been to understand the molecular mechanisms underlying the role of mammalian RAD51 paralogs in genome maintenance and tumor suppression. The investigation carried out during this study has ... -
Molecular and biochemical studies on components of transcription regulation, tropane alkaloid biosynthesis and signal transduction in the medicinal plant Datura metel L.
Tropane alkaloids (TA) are among the oldest medicines known to humankind as they possess hallucinogenic and poisonous properties. Datura metel, an herbaceous plant, belongs to the family Solanaceae whose members are well ... -
Understanding mRNA fate regulation by RGG motif protein, Sbp1
Cellular events that rely on translation regulation has been well established, however the molecular details of factors involved in bringing translation control remains inadequately explored. RNA binding proteins form ... -
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 ...
