Towards The Understanding Of The Structural Biology Of Histone H1
(Indian Institute of Science, 2005-11-23)In the eukaryotic nucleus, an immense length of DNA is compactly packaged to generate an ordered three-dimensional hierarchical structure called chromatin (van Holde, 1988; Wolffe, A.P, 1998). This organization forms a ... -
Trade-offs And Social Behaviour In The Cellular Slime Moulds
(2014-08-01)By combining laboratory experiments with field work, I have looked at the following aspects of cellular slime mould (CSM) biology: (a) the genetic structure of social groups (fruiting bodies) in the wild and its relation ... -
Transcription In Mycobacteria : From Initiation To Elongation
(2015-01-02)The global re-emergence of TB and other mycobacterial infections have underscored the need for a thorough investigation of the biology of the causative agent, Mycobacterium tuberculosis, at the molecular level. The peculiar ... -
Transcription Initiation and its Regulation in Mycobacterium Tuberculosis
(2018-02-27)The ability to fine-tune gene-expression in the adverse conditions during pre and post infectious stages has contributed in no small measure to the success of Mycobacterium tuberculosis as the deadly pathogen. Multiple ... -
Transcription termination in Mycobacteria
Transcription termination is one of the key events of gene expression that decides the boundary of the gene. Termination either before the stop codon or transcriptional read-through into the downstream gene both have ... -
Transcriptional Analysis Of The Principal Cell Division Gene ftsZ Of Mycobacterium Tuberculosis And Mycobacterium Smegmatis
(2009-03-04)The success of Mycobacterium tuberculosis as a pathogen is due to its remarkable ability to: (i). adapt to and survive inside activated macrophages under nonproliferating condition, (ii). put up drug resistance ... -
Transcriptional and Posttranscriptional Regulation of the Tumor Suppressor CDC73 in Oral Squamous Cell Carcinoma : Implications for Cancer Therapeutics
(2018-04-16)CDC73, also known as HRPT2, is a tumour suppressor gene whose expression is lost or downregulated in parathyroid, renal, breast, uterine and gastric cancers. However, the reports regarding the role of CDC73 in oral squamous ... -
Transcriptional Regulation And The Role Of Galactose Metabolism In The Virulence Of Candida Albicans
(2009-06-24)Candida albicans, a commensal of gastrointestinal and uro-vaginal tract can cause superficial as well as life threatening disseminated infections under conditions of lowered immunity of the host such as HIV infection, ... -
Transcriptional Regulation By A Biotin Starvation- And Methanol-Inducible Zinc Finger Protein In The Methylotrophic Yeast, Pichia Pastoris
(2016-05-04)Pichia pastoris, a methylotrophic yeast is widely used for recombinant protein production. It has a well characterized methanol utilization (MUT) pathway, the enzymes of which are induced when cells are cultured in the ... -
Transcriptional Regulation By Nuclear Receptor Homodimers Binding To The Direct Repeat Motif DR1 : Investigations In An in vitro Transcription System Derived From Rat Liver Nuclear Extracts
(Indian Institute of Science, 2005-11-23)Nuclear receptors (NRs) are important transcription factors involved in the regulation of a variety of physiological processes such as embryonic development, cell differentiation and homeostasis (for review, see Mangelsdorf ... -
Transcriptional regulation of a microRNA encoding gene MIR319C during leaf development in Arabidopsis thaliana
The evolutionarily conserved microRNA miR319 and its target transcription factors encoded by five CIN-TCPs (TCP2, 3, 4, 10 & 24) regulate leaf morphogenesis in Arabidopsis by triggering the division to differentiation ... -
Transcriptional Regulation of Fatty Acid Transport by Sirtuin 2
The heart is a highly dynamic organ and under normal physiological conditions, it is heavily dependent on fatty acid oxidation to meet its energy requirements (Abumrad and Goldberg 2016). Fatty acid transport is a crucial ... -
Translation in Erythroid cells
Erythrocytes are specialized cells that perform the crucial function of gas exchange in all vertebrates. Regulation of gene expression was believed to be absent in these cells due to the absence of nucleus. It was also ... -
Translation in the 3'Untranslated Region of Mammalian Transcripts
Mammalian mRNAs generally have a 5'UTR (untranslated region), a coding DNA sequence, and a 3'UTR. The 3'UTR of mRNA is generally believed to be the untranslated region of the mRNA. However, there are certain instances ... -
Translational Control Of p53 And Its Isoform By Internal Initiation
(2010-07-19)Tumor suppressor p53, the guardian of the genome, has been intensely studied molecule owing to its central role in maintaining cellular integrity. While the level of p53 protein is maintained low in unstressed conditions, ... -
Translational readthrough of AGO1 mRNA and its regulation by let-7a microRNA
During translation, the message encoded in mRNAs is decoded by ribosomes to synthesize proteins following strict canonical decoding rules. This process is tightly regulated and several mechanisms exist in cells that ensure ... -
Tree Diameter Growth : Variations And Demographic Niches In A Tropical Dry Forest Of Southern India
(2009-08-03)Tree growth influences forest community dynamics and responses to environmental variations, but currently is not well understood. Tree growth in highly diverse wet tropical forests have been well studied and characterised ... -
