Homocysteine is an independent risk factor for cardiovascular diseases. It is also known to be associated with a variety of complex disorders. While there are a large number of independent studies implicating homocysteine in isolated pathways, the mechanism of homocysteine induced adverse effects are not clear. Homocysteine-induced modulation of gene(More)
Epigenetic modifications, especially alteration in DNA methylation, are increasingly being recognized as a key factor in the pathogenesis of complex disorders, including atherosclerosis. However, there are limited data on the epigenetic changes in the coronary artery disease (CAD) patients. In the present study we evaluated the methylation status of genomic(More)
Mycobacterium avium subspecies paratuberculosis (MAP) causes Johne's disease (JD or paratuberculosis) in animals and has also been implicated in Crohn's disease of humans. It has been shown that MAP is endemic in animal population of India. Understanding of heterogeneity among MAP strains is important both for diagnosis and design control measures.(More)
BACKGROUND & OBJECTIVE Mercaptopurine, azathioprine, and thioguanine, used as antineoplastic agents and immunosuppressants are catabolized by thiopurine methyltransferase (TPMT) enzyme, which exhibits genetic polymorphism. Genotyping patients and the population to which the patients belong, is important for effective treatment and reducing toxicity. There(More)
The sequencing of the complete genome of M. tuberculosis H37Rv has resulted in the recognition of four mce operons in its genome by in silico analysis. In an attempt to understand the significance of the redundancy of mce operons, we analyzed the expression profile of mce operons after different periods of growth in culture as well as during in vivo(More)
The expression of genes in transgenic mice is known to be influenced by the site of integration even when they carry their own promoter elements and transcription factor binding sites. The cytomegalovirus (CMV) promoter, a strong promoter often used for transgene expression in mammalian cells in culture, is known to be silenced by DNA methylation and(More)
The homologues of yeast INO80 are identified across phyla from Caenorhabditis elegans to human. In Drosophila it has been shown that dINO80 forms a complex with Pleiohomeotic but does not interact with Hox PRE (polycomb responsive element). As some proteins of the INO80 complex are implicated in homeotic gene regulation, we examined if dINO80 is involved in(More)
Proteins belonging to SNF2 family of DNA dependent ATPases are important members of the chromatin remodeling complexes that are implicated in epigenetic control of gene expression. The yeast Ino80, the catalytic ATPase subunit of the INO80 complex, is the most recently described member of the SNF2 family. Outside the conserved ATPase domain, it has very(More)
Mammalian cell entry (mce) operons, implicated in the entry of mycobacteria into host cells, are present in pathogenic and saprophytic species. It is likely that the genes in these operons have functions other than those required for entry into host cells. Using in silico analysis we have identified domains within the mce operons that might justify their(More)
The proteins belonging to SWI2/SNF2 family of DNA dependent ATPases are important members of the chromatin remodeling complexes that are implicated in epigenetic control of gene expression. We have identified a human gene with a putative DNA binding domain, which belongs to the INO80 subfamily of SWI2/SNF2 proteins. Here we report the cloning, expression,(More)
