received: 23/sep/2008, accepted: 23/nov/2008oct-4/ pou5f1/ oct-3, a pou domain family protein acts as a crucial transcription factor dur- ing embryonic development. it helps in maintenance of self renewal as well as pluripotential state of embryonic stem (es) cells. its expression starts right from 2 cell stage especially prior to 8 cell stage till the blastocyst stage where it is strongly exp...

Protein Phosphatase 6 down-regulation in keratinocytes is a pivotal event that amplifies the inflammatory circuits psoriasis, indicating restoration of protein phosphatase can be rational strategy for psoriasis treatment. Through phenotypic screen, we here identify L-menthol ameliorates psoriasis-like skin inflammation by increasing keratinocytes. Target identification approaches reveal an indi...

Expression of the CD4 and CD8 glycoproteins is a tightly regulated process tied to the maturation of functionally distinct classes of thymocytes. Therefore, understanding of the mechanism of expression of the genes encoding CD4 and CD8 is likely to yield important insight into regulation of the differentiated functions of T cells. Here, we report the identification of a T-cell-specific enhancer...

Aptamers, or single stranded oligonucleotides, are produced by systematic evolution of ligands by exponential enrichment, abbreviated as SELEX. In the amplification and regeneration step of SELEX technique, dsDNA is conversed to ssDNA. Asymmetric PCR is one of the methods used for the generation of ssDNA. The purpose of this study was to design a random DNA library for selection of aptamers wit...

The mouse vascular smooth muscle α-actin (SMA) gene enhancer is activated in fibroblasts by TGFβ1, a potent mediator of myofibroblast differentiation and wound healing. The SMA enhancer contains tandem sites for the Sp1 transcriptional activator protein and Purα and β repressor proteins. We have examined dynamic interplay between these divergent proteins to identify checkpoints for possible con...

Regulatory genes directing embryonic development are expressed in complex patterns. The Drosophila homeobox gene fushi tarazu (ftz) is expressed in a striped pattern that is controlled by several discrete and large cis- regulatory elements. One key cis-element is the ftz proximal enhancer which is required for stripe establishment and which mediates autoregulation by direct binding of Ftz prote...
