Elucidation Of Differential Role Of A Subunit Of RNA Polymerase II, Rpb4 In General And Stress Responsive Transcription In Saccharomyces Cerevisiae
(2010-09-14)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 regulatory pathways. ... -
Epileptiform Activity Induced Alterations In Ca2+ Dynamics And Network Physiology Of Hippocampal Neurons - In Vitro Studies
(2010-07-15)Epilepsy is characterized by the hyperexcitability of individual neurons and hyper synchronization of groups of neurons (networks). The acquired changes that take place at molecular, cellular and network levels are important ... -
Functional Characterization Of Proteins Involved In Cell To Cell Movement Of Cotton Leaf Curl Kokhran Virus- Dabawali
(2010-09-13)Viruses are submicroscopic obligate parasites and depend on the host cell for their growth and reproduction. Plants are infected by diverse group of viruses that mostly possess RNA as their genome. As exception, viruses ... -
Glycodelin A : A Novel Immunoregulatory Lectin Of The Female Reproductive Tract : Molecular Mechanism Of GdA-Induced Apoptosis In Activated T Cells
(2010-08-06)Glycodelin is a 162 amino acid secreted glycoprotein classified as a member of the lipocalin (carriers of small hydrophobic molecules) superfamily based on the presence of lipocalin signature motifs in its primary sequence. ... -
Human Spermatogenesis : Differential Gene Expression And Regulation
(2010-08-24)Spermatogenesis is a complex process of male germ cell development in which the diploid spermatogonia undergo series of mitotic divisions and differentiation steps culminating into the preleptotene spermatocytes which then ... -
Identification And Characterisation Of Two Silencing Barrier Sequences In Saccharomyces Cerevisiae
(2010-07-21)In eukaryotic cells, genomic DNA exists as chromatin in association with histone octamers called nucleosomes, and various other chromatin proteins. Chromatin structure varies along the chromosome and this influences the ... -
Identification Of Domains Of The Follicle Stimulating Hormone Receptor Involved In Hormone Binding And Signal Transduction
(2010-10-08)The glycoprotein hormones, Luteinizing Hormone (LH), human Chorionic Gonadotropin (hCG), Follicle Stimulating Hormone (FSH) and Thyroid Stimulating Hormone (TSH) are heterodimeric proteins with an identical α-subunit ... -
Mapping Of Glycoprotein Hormone-Receptor Interactions Using Hormone Analogs And Antibodies
(2010-09-21)The glycoprotein hormone family comprising of Luteinizing Hormone (LH), Chorionic Gonadotropin (hCG), Follicle Stimulating Hormone (FSH) and Thyroid Stimulating Hormone (TSH) plays important role in reproduction and overall ... -
Molecular Actions Of Arecoline, An Alkaloid Implicated In The Manifestation Of Oral Submucous Fibrosis (OSMF)
(2010-07-21)The pathogenesis of oral submucous fibrosis (OSMF) is due to a complex interplay between the production and degradation of extracellular matrix (ECM) protein components. In tissue fibrosis, there is a net accumulation of ... -
Molecular Genetic Studies On Pre-mRNA Splicing Factors Of Fission And Budding Yeasts
(2010-10-05)Nuclear pre-mRNA splicing proceeds via two mechanistically conserved consecutive trans-esterification reactions catalyzed by the spliceosome. The ordered coalescence of spliceosomal snRNPs and splicing factors on the ... -
