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, ... -
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 ... -
Processing Of DNA Recombination And Replication Intermediates By Mycobacterium Tuberculosis RuvA And RuvB Proteins
(2013-06-14)Homologous recombination (HR) is a highly conserved cellular process involved in the maintenance of chromosomal integrity and generation of genetic diversity. Biochemical and genetic studies have suggested that HR is ... -
Production Of Anticancer Drug Taxol And Its Precursor Baccatin III By Fusarium Solani And Their Apoptotic Activity On Human Cancer Cell Lines
(2013-06-24)Taxol (generic name paclitaxel), a plant‐derived antineoplastic agent, was originally isolated from the bark of the Pacific yew, Taxus brevifolia. Obtaining taxol from this source requires destruction of trees. It has ... -
Promoter Prediction In Microbial Genomes Based On DNA Structural Features
(2013-02-25)Promoter region is the key regulatory region, which enables the gene to be transcribed or repressed by anchoring RNA polymerase and other transcription factors, but it is difficult to determine experimentally. Hence an ... -
Protein-DNA Graphs And Interaction Energy Based Protein Structure Networks
(2013-01-29)Proteins orchestrate a number of cellular processes either alone or in concert with other biomolecules like nucleic acids, carbohydrates, and lipids. They exhibit an intrinsic ability to fold de novo to their functional ... -
Role of TCP4 Transcription Factor in the Maturation Program of Arabidopsis Life Cycle
(2018-07-28)TCP4 as an integrator of key developmental events A striking aspect of plant life is their sedentary life-style. Though it relieves them of the obligation of forming a complex body organization, it exposes them to ... -
Sequence Analysis And Design Of Immunogens From The Stem Domain Of Influenza Hemagglutinin
(2013-07-10)Influenza is an important respiratory pathogen that infects several million people each year. Currently available flu vaccines have to be updated regularly in order to be effective as the virus changes its composition by ... -
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 ... -
Structural And Mechanistic Studies On Receptor Protein Tyrosine Phosphatases From Drosophila Melanogaster
(2013-06-20)Protein Tyrosine Phosphatases (PTPs) initiate, modulate and terminate key cellular processes by dephosphorylating phosphotyrosine (pY) residues on signaling proteins. The coordinated action of PTPs with their cognate ... -
Studies On Embryonic Stem Cells From Enhanced Green Fluorescent Protein Transgenic Mice : Induction Of Cardiomyocyte Differentiation
(2013-07-17)Genesis of life begins with the fusion of female and male haploid gametes through a process of fertilization leading to the formation of a diploid cell, the zygote. This undergoes successive cleavage divisions forming 2-, ... -
Studies On The Functional Roles Of Peptidase N, A M1 Family Member, During Stress And Infection
(2014-08-11)The cytosolic protein degradation pathway, performed by ATP-dependent proteases and ATP-independent peptidases, plays important roles in several cellular activities, e.g. cell division, cell cycle progression, intracellular ... -
Studies On The Mechanism Of Uracil Excision Repair In Escherichia Coli And Structure-Function Relationship Of Single Stranded DNA Binding Proteins From Escherichia Coli And Mycobacterium Tuberculosis
(2014-12-11)To maintain the genomic integrity, cell has evolved various DNA repair pathways. Base Excision Repair pathway (BER) is one such DNA repair pathway which is dedicated to protect DNA from small lesions such as oxidation, ... -
