The degree of inhibition of rat intestinal alkaline phosphatase by L-phenylalanine was highly pa-dependent and varied from 0 to 66% within a pH range of ‘7.8 to 10.4, exhibiting a peak at pH 9.2 and 8.7 for phenylphosphate and /3glycerophosphate, respectively. Vm,, was also a function of pH with and without the inhibitor. Rat intestinal alkaline phosphatase exhibited maximum enzyme activity at ...

Purpose: Embryonic stem (ES) cells are derived from the inner cell mass of blastocysts with self-renewal and pluripotency characteristics. These cells have potential for studies of in vitro differentiation, gene function, etc. This study was, therefore, initiated to establish new ES lines and evaluate the effects of strain on ES cell production. Materials and Methods: 3-5 day blastocysts were ...
It is shown here that treatment of metaphase-arrested HeLa cells with okadaic acid (0.15-2.5 microM) leads to dephosphorylation of histone H1. This effect is presumably due to the specific ability of okadaic acid to inhibit protein phosphatases 1 and/or 2A, because okadaic acid tetraacetate, which is not a phosphatase inhibitor, has no effect. Dephosphorylation of H1 does not occur if okadaic a...
شوری خاک یکی از عوامل مهم محیطی است که منجر به کاهش عملکرد گیاهان زراعی می شود. شناخت مکانیسم های مقاومت گیاهان در برابر تنش ها می تواند به شناسایی ژن های مقاومت و کاربرد آن ها در اصلاح گیاهان و افزایش محدوده کشت گیاهان منجر شود. روش آنالیز expressed sequence tag (est) و داده های ریزآرایه راهی سریع و منطقی برای شناسایی ژن های نامزد جدید برای مقاومت به تنش ها می باشد. در این تحقیق تعداد 2 کتابخا...
Protein phosphatase 2A (PP2A) is a ubiquitous serine/threonine implicated in wide variety of regulatory cellular functions. PP2A abundant the mammalian nervous system, and dysregulation its functions associated with myriad neurodegenerative disorders. Additionally, has oncologic implications, recently garnering attention emerging as therapeutic target because antitumor effects potent inhibitor,...
