Spatio-Temporal Control Of Drosophila Indirect Flight Muscle Development And Maintenance By The Transcription Factor Erect Wing
(2016-04-27)Muscle development involves concerted action of a repertoire of mechanisms governing myoblast proliferation, migration, fusion and differentiation. Subsequently, there are cellular events administrating proper muscle ... -
Spatio-temporal Regulation of GPCR mediated MAPK Transactivation in Living Cells
Signal transduction is a mode of cellular communication essential for an organism’s sustenance and survival. Cell communication in higher organisms is largely executed by two classes of cell surface receptors i.e. G-protein ... -
Species Ranges, Richness and Replacement of Trees in the Evergreen Forests of the Western Ghats
(2018-05-14)It has been more than two centuries since the latitudinal pattern of increase in taxonomic richness from poles to equator was first documented. After two centuries of research, and with more than two dozen hypotheses ... -
Spermatogenomics : Correlating Testicular Gene Expression to Human Male Infertility
(2018-06-13)Spermatogenesis is a complex and coordinated process of formation of sperms from the precursor spermatogonia, occurring inside the unique environment existing in the seminiferous epithelium. This process of development, ... -
Spike-Timing-Dependent Plasticity at Excitatory Synapses on the Rat Subicular Pyramidal Neurons
(2018-05-08)The subiculum is a structure that forms a bridge between the hippocampus and the entorhinal cortex (EC) in the brain, and plays a major role in the memory consolidation process. It consists of different types of pyramidal ... -
SRF regulates the generation of neuroprotective astrocytes in the brain
In response to injuries, infections or in neurodegenerative disorders, astrocytes get activated to become reactive. This phenomenon is called astrogliosis and is marked by a spectrum of changes which encompasses structural, ... -
Starvation Response In Mycobacterium Smegmatis : A Tale Of Two Proteins
(2010-10-19)The Dps (DNA-Binding Protein from Starved Cells) proteins are a class of stress-specific proteins with a major role in protecting DNA during the stationary phase of bacterial growth, through direct physical binding as well ... -
Stereochemical studies on peptide and protein structures: Implications for validation, flexibility, and dynamics
Accuracy of 3-D structures of proteins is crucial, both in terms of its agreement with the experimental data used to determine the structure and stereochemistry, especially when they are utilized for applications like drug ... -
Stimulus statistics and HCN current mediated resonance sets the scale of input-output mapping in Stellate cells of the Medial Entorhinal Cortex
The functional significance of the computations performed by Stellate cells of the Medial Entorhinal Cortex, proven time and again, makes them insightful, yet intriguing. The gradients of the intrinsic properties of these ... -
Stop codon readthrough in MTCH2 mRNA and its role in mitochondrial physiology
Stop codon readthrough is the process in which translation continues beyond a stop codon till a downstream, in-frame stop codon generating a polypeptide with a C-terminal extension. MTCH2 was selected as a potential ... -
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 ... -
Stress Physiology of Free-ranging Asian Elephants (Elephas maximus) : Influence of Ecological and Anthropogenic Stressors
(2018-07-09)Various ecological and human-induced disturbances play an important role in defining the health of an animal. To cope up with such threats or challenges to its homeostasis, an animal responds by secreting stress hormones ... -
Stress Response In Salmonella And Its Role In Pathogenesis
(2011-02-08)Chapter: 1 Introduction Genus Salmonella is a Gram-negative rod shaped facultative anaerobic bacteria that can survive inside the host macrophages and cause persistent infection. Salmonella Typhimurium, Salmonella Typhi ... -
Stress Signaling In Development And Carcinogenesis : Role Of AMP-Activated Protein Kinase
(2013-08-05)Rapidly growing tumor cells outgrow their blood supply resulting in a microenvironment with reduced oxygen and nutrients. Using an in vitro transformation model we found that cancer cells expressing the SV40 ST antigen ... -
Stringent Response In Mycobacteria: Molecular Dissection Of Rel
(2007-11-29)Adaptation to any undesirable change in the environment dictates the survivability of many microorganisms. Such changes generate a quick and suitable response, which guides the physiology of bacteria. Stringent response ... -
Structural and Biochemical Analysis of DNA Processing Protein A (DprA) from Helicobacter Pylori
(2018-05-09)H. pylori has a panmictic population structure due to high genetic diversity. The homoplasy index for H. pylori is 0.85 (where 0 represents a completely clonal organism and 1.0 indicates a freely recombining organism) which ... -
Structural and Biochemical Studies on Mycobacterial Uracil- DNA N-glycosylase and Mut T1
Maintenance of the genomic integrity of the cell is crucial for the survival and successful propagation of an organism. However, this integrity is under continuous threat from DNA-damaging agents. In addition, errors in ... -
Structural and biochemical studies on mycobacterial Uracil-DNA glycosylase (Ung) and MutT1, key proteins involved in maintaining the genomic integrity in Mycobacteria
Maintaining genomic integrity is indispensable for the survival and propagation of an organism. Failure to do so can cause mutations involving structural and functional aberrations, leading to severe diseases. The causative ... -
Structural And Biophysical Analysis Of The Regulatory Mechanism Of Mycobacterium Tuberculosis Sigma Factors
(2010-12-07)Mycobacterium tuberculosis has one ribosomal RNA operon. The survival of this bacillus thus depends on a transcription mechanism that can effectively couple gene expression to changes in the environment. σ factors are ...
