Ants, Figs, Fig Wasps : The Chemical Ecology Of A Multitrophic System
(2013-04-01)Plant–animal interaction systems are complex food webs where the members—plants, pollinators, herbivores, parasites and predators of the pollinators/herbivores—interact with each other in ways which maximize their own ... -
Arabidopsis Serine/Threonine/Tyrosine Protein Kinase : Implications in Growth And DEvelopment
(2018-07-19)Protein phosphorylation is a key cellular regulatory mechanism. Phosphorylation can either activate or inhibit the function of a particular protein. Activation of protein kinases has been implicated in response to light, ... -
Aromatic Beta-Glucoside Utilization In Shigella Sonnei : Comparison With The Escherichia Coli Paradigm
(2010-12-01)The aromatic beta-glucosides of plant origin, salicin and arbutin, serve as carbon sources for the sustenance of bacteria when ‘preferred’ sugars are absent in the environment. In the family Enterobacteriaceae, there are ... -
Aromatic Interactions In Peptides : Designed Helices And β-Hairpins
(2009-04-15)Design of complex protein folds requires complete understanding of the stereochemical principles that govern polypeptide chain folding. Extensive studies on design and synthesis of specific secondary structures like ... -
Astrocytes regulate oligodendrocyte development and myelination in the mammalian brain
Oligodendrocytes (OLs), a type of glial cell, are the main myelinating cells of the mammalian central nervous system (CNS), enabling efficient saltatory mode of nerve conduction. On the other hand, astrocytes, another glial ... -
Astroglial development as the basis for the effects of early life stress on adult depressive-like behavior
This thesis investigates the enduring effects of early-life stress, specifically maternal separation, on astroglial population and the subsequent behavioral outcomes in adult mice. While the persistent impact of early-life ... -
Attributes Of Royalty In The Primitively Eusocial Wasp Ropalidia marginata : Pheromone, Ovaries And Behavior
(2012-12-07)This thesis has looked at the proximate mechanisms by which eusociality is maintained in colonies of the primitively eusocial wasp Ropalidia marginata. Unlike other typical primitively eusocial species, the R, marginata ... -
Aβ42-mediated dendritic spine loss in an in-vitro model of Alzheimer’s disease
The results from this study establish the molecular mechanism underlying the Aβ42-mediated dendritic spine loss observed in the APP/PS1 mouse model of AD. Further, this study highlights the role of Aβ42 in altering the ... -
Biochemical and functional characterisation of cyclic AMP-binding, universal stress proteins from mycobacteria
The genus Mycobacterium harbours several pathogenic species, including M. tuberculosis, the causative agent of tuberculosis, which alone is responsible for nearly 1.3 million deaths globally every year. Understanding the ... -
Biochemical And Functional Characterization Of Evolutionarily Conserved Metallophosphoesterases The 239FB/AB Family
(2010-12-30)With the advent of large scale genome sequencing efforts along with more sophisticated methods of genetic mapping, a number of loci have been identified that are associated with human diseases. Intriguingly, many genes ... -
Biochemical and Functional Characterization of Mycobacterium Tuberculosis Nucleoid-Associated Proteins H-NS and mIHF
(2018-08-11)Bacteria lack nucleus and any other membrane-bound organelles. Hence all the cellular components, including proteins, DNA, RNA and other components are located within the cytoplasm. The region of the cell which encompasses ... -
Biochemical and functional characterization of the enigmatic MPPED1/MPPED2 metallophosphodiesterases
Evolutionarily conserved genes in nature have been known to perform critical functions inside the cell. Earlier bioinformatic analysis performed in our laboratory identified mammalian orthologs of Rv0805, a novel class III ... -
Biochemical and Functional Characterization of the Mycobacterial PdtaS-PdtaR Two Component System
Two-Component Systems (TCSs) are primarily prokaryotic modes of cell signaling involving a receptor sensor kinase (SK) that senses stimuli and a response regulator (RR) that effects a response, usually at the level of ... -
Biochemical and Functional Studies on the Evolutionarily Conserved MPPED1/MPPED2 Protein Family
(2018-05-16)A large number of evolutionarily conserved genes have been identified by comparative genomics approaches. However, a considerable fraction of these genes lack functional characterization despite the availability of several ... -
Biochemical And Molecular Insights Into β-Hydroxyacyl-Acyl Carrier Protein Dehydratase (FabZ) From Plasmodium Falciparum
(2008-10-14)Malaria, caused by Plasmodium, is one of the most devastating infectious diseases of the world in terms of mortality as well as morbidity (WHO, 2002). The development of resistance in the Plasmodium falciparum against the ... -
Biochemical and structural studies to provide insights into initiator tRNA delivery by eIF2A in noncanonical translation initiation
Eukaryotic initiation factor 2A (eIF2A), a non-canonical translation initiation factor, delivers initiator tRNA (tRNAi) onto the 40S ribosomal subunit in a codon-dependent and GTP-independent manner, unlike the canonical ... -
Biochemical Characterization Of An Acid-Adaptive Type III DNA Methyltransferase From Helicobacter Pylori 26695 And Its Biological Significance
(2014-12-15)Enzyme DNA methylation is an important biochemical process that imprints DNA with additional information. DNA methylation is catalyzed by S-adenosyl-L-methionine (AdoMet)-dependent methyltraferases (MTases). Prokaryotic ... -
Biochemical Characterization Of Heat Shock Protein 90 From Plasmodium Falciparum
(2013-06-07)Molecular chaperones are a group of proteins which maintain cellular homeostasis by assisting de novo protein folding and their refolding to native state after destabilization due to external stress. They are also known ... -
