Studies On The Functional Roles Of Peptidase N, A M1 Family Member, During Stress And Infection
(2014-08-11)The cytosolic protein degradation pathway, performed by ATP-dependent proteases and ATP-independent peptidases, plays important roles in several cellular activities, e.g. cell division, cell cycle progression, intracellular ... -
Studies On The Mechanism Of Uracil Excision Repair In Escherichia Coli And Structure-Function Relationship Of Single Stranded DNA Binding Proteins From Escherichia Coli And Mycobacterium Tuberculosis
(2014-12-11)To maintain the genomic integrity, cell has evolved various DNA repair pathways. Base Excision Repair pathway (BER) is one such DNA repair pathway which is dedicated to protect DNA from small lesions such as oxidation, ... -
Studies On The Mechanisms Involved In Thymic Atrophy During Salmonella Enterica Serovar Typhimurium Infection
(2015-09-04)T lymphocytes are an essential component of the adaptive immune response and are highly versatile in function. Each T cell has a unique T cell receptor that can recognize an antigenic peptide in the context of the major ... -
Studies On The Molecular Mechanism Of Cytokinin Action: Involvement Of Ca2+, Protein Kinase And Concurrent Protein Synthesis In Signaling Of Cytokinin-Induced Expression Of Pathogenesis-Related Enzymes In Cucumber
(Indian Institute of Science, 2005-12-08)Phytohormones act as signals to regulate plant growth and development by modulation of gene expression in response to internal developmental cues or external environmental stimuli, such as light and pathogen infection. ... -
Studies On The Phenomenon Of Blastocyst Hatching: Role Of Cysteine Proteases
(2007-11-16)The mammalian embryo is encased in a glycoproteinaceous covering, the zona pellucida (ZP/zona) during preimplantation development. Prior to implantation into the recipient maternal endometrium, the blastocyst has to hatch ... -
Studies on the post-transcriptional regulation of genes of glutamate utilization pathway in Pichia pastoris and a role for Retrograde regulation protein 1
The methylotrophic yeast, Pichia pastoris can utilize compounds such as glucose, glycerol, methanol, acetate, amino acids, or oleic acid as the sole source of carbon. However, the regulation of synthesis of key enzymes of ... -
Studies on the promoter specificity determinants and modulators of the prokaryotic transcription machinery
Bacteria adapt to a wide range of environmental conditions by synchronizing transcription with changes in the extracellular environment. This is achieved by the synchronized action of two-component systems, Extra Cytoplasmic ... -
Studies on the regulatory roles for Retinoic Acid (RA) during host-microbial interaction : implications for S. aureus and C. albicans infections
Chronic inflammatory disorder is one of the leading causes of death worldwide. Association between pathogenic infection and inflammation governs tissue homeostasis, which relies on extensive crosstalk among signaling ... -
Studies On The Roles Of Intracellular Ca2+ And Reactive Oxygen Species During CD4+ T Cell Activation : Influence Of Signal Strength
(2011-03-08)Optimal CD4+ T cell activation is key to the generation of a productive immune response. Naïve circulating CD4+ T cells are quiescent under normal conditions and undergo activation only upon encounter of the T cell receptor ... -
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 ... -
Studies On The Structural And Biological Properties Of Rotavirus Enterotoxigenic Non-structural Protein 4 (NSP4)
(2013-04-01)Rotavirus is the major cause of infantile gastroenteritis. Each year more than 600,000 young children are estimated to die in developing countries throughout the world. Rotavirus infection can be either symptomatic or ... -
Studies on Δ40p53 mediated regulation of specific coding and non-coding RNAs: Consequences on cellular processes
p53 is a crucial transcriptional regulator which influences almost every possible pathway that impinges on the life of a cell. As expected of such an instrumental protein, the molecular network of p53 is as diverse as it ... -
Study of Ca2+-Mediated Signal Transduction During Embryogenesis In Sandalwood (Santalurm Album L.) And Characterization Of An Early Development-Specific CDPK
(Indian Institute of Science, 2005-12-08)Calcium ion plays a pivotal role as second messenger during signal/response coupling in plant cells (Trewavas, 1999). Elevations of cytosolic Ca2+ occur in plants as a consequence of abiotic and biotic stresses, environmental ... -
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), ... -
Study Of Rpb4, A Component Of RNA Polymerase II As A Coordinator Of Transcription Initiation And Elongation In S. Cerevisiae
(2017-05-24)RNA polymerase II (Pol II) is the enzyme responsible for the synthesis of all mRNAs in eukaryotic cells. As the central component of the eukaryotic transcription machinery, Pol II is the final target of transcription ... -
