Cell Surface Of Mycobacterium Smegmatis At The Stationary Phase : Regulation Of Gene Expression
(2009-05-21)Tuberculosis remains one of the oldest diseases known to mankind but still persists as a very major risk. Discovery of several antimycobacterials was marked by a steady decline in the active cases of pulmonary tuberculosis. ... -
Characterization Of Down Regulated Genes In Astrocytoma
(2011-07-27)Gliomas are the most common primary brain tumors and include astrocytomas, oligodendrogliomas and oligoastrocytomas. Astrocytomas have a high frequency of occurrence as compared to the other gliomas and several studies ... -
Epigenetic Regulators Of Development In The Social Amoeba Dictyostellium Discoideum : The Roles Played By Histone Deacetylases And Heat Shock Protein 90
(2011-01-20)The major evolutionary transition from single-celled to multicellular life is believed to have occurred independently of the main metazoan lineages in the cellular slime moulds, of which Dictyostelium discoideum is the ... -
Expression Profiling Of Genes Regulated By TGF-β : Role Of Multiple Signaling Pathways
(2009-05-12)Transforming growth factor-β (TGF-β) is the proto-type member of a super family of secreted proteins comprised of several structurally related, but functionally divergent proteins like the BMP, activin, inhibin, mullerian ... -
Functional Characterization Of The Saccharomyces Cerevisiae Splicing Factor, Prp17 In pre-mRNA Splicing And Cell Cycle Progression: An Analysis Through Global Expression Profiling, Protein Interactions And Spliceosomal Associations
(2007-08-30)The presence of introns in all the eukaryotic genomes identified so far underscores the fundamental and ubiquitous role of pre-mRNA splicing. The spliceosomal machinery, comprised of five small nuclear RNAs and several ... -
Functions For OsMADS2 And OsMADS1 As Master Regulators Of Gene Expression During Rice Floret Meristem Specification And Organ Development
(2013-06-06)Plant reproductive development begins when vegetative shoot apical meristems change their fate to inflorescence meristems which develop floral meristems on the flanks. This process of meristem fate change and organ development ... -
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 Characterization Of A Virus Inducible Non Coding RNA (VINC)
(2010-12-29)Non-protein coding eukaryotic genome sequences often referred to as junk DNA are estimated to encode several non-coding RNAs (ncRNAs) which may account for nearly 98% of all genomic output in humans. The output of such a ... -
Mechanism Of Interaction Of Escherichia Coli σ70 With Anti-Sigma Factors
(2009-08-03)In bacteria, the RNA polymerase (RNAP) consists of the following subunits: α2, β, β’, ω and σ. The core RNAP (α2ββ’ω) possesses the polymerising activity and it associates with one of the sigma factors to initiate transcription ... -
Mechanism Of mom Gene Transactivation By Transcription Factor C Of Phage MU
(Indian Institute of Science, 2007-04-26)Regulation of transcription initiation is the major determining event employed by the cell to control gene expression and subsequent cellular processes. The weak promoters, with low basal transcription activities, are ... -
Molecular Approaches To understand Cellular Differentiation - A Study Using BeWo Choriocarcinoma Cells
(2010-05-24)Cellular differentiation is a complex but fascinating process in all multicellular organisms. Differentiation can involve changes in numerous aspects of cell physiology; size, shape, polarity, metabolic activity, responsiveness ... -
Molecular Characterization Of The SLC22A18AS Gene From The Imprinted Human Chromosome Segment 11p15.5
(2011-02-21)The imprinting status of the SLC22A18AS gene, located in the human chromosome segment 11p15.5, was studied using PCR-SSCP analysis and fetal tissues from a battery of 17 abortuses. This gene showed monoallelic expression ... -
Regulation Of Interferon Regulatory Factor-2 mRNA Translation By 'IRES' Element : Possible Role Of trans Acting Factors
(2009-09-03)Cellular response to various stress conditions involves regulation of gene expression by different mechanisms. Translation is the final step in the flow of genetic information and regulation at this level allows an early ... -
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 ... -
Structure Function Studies Of Biologically Important Simple Repetitive DNA Sequences
(Indian Institute of Science, 2007-03-09)The recent explosion of DNA sequence information has provided compelling evidence for the following facts. (1) Simple repetitive sequences-microsatellites and minisatellites occur commonly in the human genome and (2) these ... -
A Study Of The Roles Played By The Trishanku Gene In The Morphogenesis Of Dictyostelium Discoideum
(2011-02-22)A hallmark feature of Dictyostelium development is the establishment and maintenance of precise cell-type proportions. In the case of D. discoideum, roughly 20% of the cells that aggregate form the stalk while the remaining ... -
