(p)ppGpp and c-di-GMP : A Tale of Two Second Messengers in Mycobacterium smegmatis
Nucleotide based second messengers are known to regulate wide variety of processes in all domains of life. Two such bacterial second messengers are (p)ppGpp (guanosine tetra- or pentaphosphate) and c-di-GMP (cyclic dimeric ... -
(p)ppGpp and Stress Response : Decoding the Key Pathways by Small Molecule Analogues Biophysical Methods and Mass Spectrometry
(2018-06-08)Under hostile conditions, bacteria elicit stress response. Such stress response is regulated by a secondary messenger called (p)ppGpp. (p)ppGpp is involved in wide range of functions such as GTP homeostasis, biofilm formation ... -
Panoramic View of RNA Binding Proteins (RBPs) in Glioblastoma : IMP3, an RBP, is Essential for Glioma Stem-like Cell Maintenance
Gliomas are primary brain tumors in adults that are believed to originate from different types of glial cells. Central nervous system gliomas pose particularly difficult problems because of their tendency towards malignancy, ... -
Pathogen-derived volatiles modulate flight or fight response in Caenorhabditis elegans
In nature, the interaction between two organisms largely relies on their ability to sense and respond to each other, which involves many specific chemicals and signaling pathways. Animals have evolved mechanisms to detect ... -
Patterns and Drivers of Multimodal Signalling in Diurnal Geckos
Effective communication in animals comprise emission of a signal by a signaller and a response by a receiver, such that the interaction is beneficial to either only the signaller, or both the signaller and the receiver. ... -
Peptidase N, A Major Aminopeptidase Belonging To The M1 Family : Biochemical And Functional Implications
(2009-08-05)Intracellular protein degradation is required for maintaining the cellular proteome and regulating cellular processes. This pathway involves proximal ATP-dependent proteases that unfold and translocate proteins targeted ... -
Peroxisomal Targeting Of Pichia Pastoris Cytochrome C During Methanol And Fatty Acid Metabolism
(2011-03-08)Intracellular protein sorting plays a key role in the regulation of cellular metabolism, gene expression, signal transduction and a number of other cellular processes. Proteins targeted to specific cellular compartments ... -
Pharmacological Modulation Of Recombinant Human Two-Pore Domain K+ Channels : Whole-Cell patch-Clamp Analysis
(2011-10-21)Background potassium currents play an important role in the regulation of the resting membrane potential and excitability of mammalian neurons. Recently cloned two- pore domain potassium channels (K2p) are believed to ... -
The Phenomenon Of Blastocyst Hatching : Role Of COX-2 And NF-kB
(2014-12-01)The zona-pellucida (zona, ZP) is an adhesion-refractory, acellular coat enclosing the rapidly growing, free-living mammalian preimplantation embryo which undergoes successive cleavage divisions to form the blastocyst, ... -
A Phylogenetic Perspective on The Phytogeography of Western Ghats
I used a finer scale data of 156 published plots across the entire latitudinal range of WG, covering most of the protected forests. The pruned phylogeny for this study consisted of 367 species, of which ~ 50% are taxa endemic ... -
Phylogeny And Biogeography Of Hemidactylus Oken, 1817 Geckos Of The Indian Subcontinent
(2013-02-25)Geckos of the genus Hemidactylus Oken, 1817 are one of the most widely distributed and species-rich groups of gekkonids. With approximately 90 species, the genus Hemidactylus accounts for 10% of the total number of species ... -
Physiological And Exogenous Means of Regulating DNA Damage Response : Insights into Mechanisms of DNA Repair And Genomic Instability
(2017-09-23)Maintenance of genomic integrity with high fidelity is of prime importance to any organism. An insult which may result in compromised genome integrity is prevented or its consequences are monitored by advanced cellular ... -

Physiological Interactions between Neuronal Active Conductances And Inositol Trisphosphate Receptors in Neurons and Astrocytes
(2018-07-23)Intricate interactions among constituent components are defining hallmarks of biological systems and sculpt physiology across different scales spanning gene networks to behavioural repertoires. Whereas interactions among ... -
Physiological Role of Arr, an ADP-ribosyltransferase in Mycobacterium smegmatis
The studies reported in this thesis address the physiological role of an antibiotic resistance gene arr, followed by establishment of the arr knockout strains (generated during the investigation) for drug testing and ... -
Physiological Role of Folate Dehydrogenase in One Carbon Metabolism of Escherichia Coli
(2018-06-08)Thesis addresses the physiological role of formyl tetrahydrofolate synthetase (Fhs) and bifunctional folate dehydrogenase (FolD) in folate mediated one carbon metabolism in bacteria. Thesis consists of 5 chapters. First ... -
A place for everything and everything in its place: Spatial organization of wasps on the nests of the primitively eusocial paper wasp Ropalidia marginata
In my thesis, I found that queens and workers in the primitively eusocial paper wasp Ropalidia marginata use space on their nests non-randomly with a majority of individuals showing spatial fidelity to small core areas, ... -
Plasticity of Intrinsic Excitability in Fast Spiking Interneurons of the Dentate Gyrus & Its Implications for Neuronal Network Dynamics
Inhibitory GABAergic neurons, although forming a minor proportion of the neuronal population in the central nervous system, have been reported to be crucial for different physiological states of the brain. Among the vast ...
