مطالعات گذشته اثر محافظتی ویتامین d در برابر سرطان پستان را گزارش کردند که این اثر توسط گیرنده ویتامین d (vdr) میانجی گری می شود. شواهد زیادی وجود دارد که نشان می دهد که شیوع سرطان پستان با انواع پلی مورفیسم روی ژن vdr ارتباط دارد. هدف این مطالعه، بررسی ارتباط بین پلی مورفیسم در توالی poly(a) ژن vdr با سطح ویتامین d (25-هیدروکسی ویتامین d) سرم و خطر ابتلا به سرطان پستان می باشد. واکنش چند شکلی ...

The translocation of specific mRNAs to dendrites and their potential for locally regulated translation are likely to serve as an effector in neuronal plasticity. Whether translation in dendrites is regulated by delivery of the RNA to sites of plasticity or a stationary pool of localized RNA undergoes enhanced translational efficiency is not clear. We show that RNA can translocate into dendrites...

BACKGROUND Adrenomedullin (AM), a 52-amino acid ringed-structure peptide with C-terminal amidation, was originally isolated from human pheochromocytoma. AM are widely distributed in various tissues and acts as a local vasoactive hormone in various conditions. METHODS In the present study, we investigated the efficacy of AM on the animal model of bleomycin (BLM)-induced lung injury. Mice were ...

The replication of human rhinovirus 2 (HRV2), a positive-stranded RNA virus belonging to the Picornaviridae, requires a virus-encoded RNA polymerase. We have expressed in Escherichia coli and purified both a glutathione S-transferase fusion polypeptide and an untagged form of the HRV2 RNA polymerase 3D(pol). Using in vitro assay systems previously described for poliovirus RNA polymerase 3D(pol)...
