Developmental and stage-specific expression of Smad2 and Smad3 in rat testis.
Members of the transforming growth factor beta type (TGFbeta) superfamily and their receptors are expressed in the testis, and are believed to play important paracrine and autocrine roles during testicular development and spermatogenesis. The Smad proteins are downstream mediators for the family of TGFbeta growth factors. Smad2 and Smad3 are associated with both TGFbeta and activin signaling. H...
متن کاملSmad2 and Smad3 cooperate and antagonize simultaneously in vertebrate neurogenesis.
The transforming growth factor beta (TGF-β) pathway plays key roles in development and cancer. TGF-β signaling converges on the Smad2 and Smad3 effectors, which can either cooperate or antagonize to regulate their transcriptional targets. Here we performed in vivo and in silico experiments to study how such cooperativity and antagonism might function during neurogenesis. In vivo electroporation...
متن کاملSMAD2, SMAD3 and SMAD4 mutations in colorectal cancer.
Activation of the canonical TGF-β signaling pathway provides growth inhibitory signals in the normal intestinal epithelium. Colorectal cancers (CRCs) frequently harbor somatic mutations in the pathway members TGFBR2 and SMAD4, but to what extent mutations in SMAD2 or SMAD3 contribute to tumorigenesis is unclear. A cohort of 744 primary CRCs and 36 CRC cell lines were sequenced for SMAD4, SMAD2,...
متن کاملSmad2 Protects against TGF- /Smad3-Mediated Renal Fibrosis
Smad2 and Smad3 interact and mediate TGFsignaling. Although Smad3 promotes fibrosis, the role of Smad2 in fibrogenesis is largely unknown. In this study, conditional deletion of Smad2 from the kidney tubular epithelial cells markedly enhanced fibrosis in response to unilateral ureteral obstruction. In vitro, Smad2 knockdown in tubular epithelial cells increased expression of collagen I, collage...

نمایشنامه به پیروی از ماهیت دوگانه اش، کارکردی دوگانه به خود می گیرد، بدین معنا که در هر دو نظام ادبی و تئاتری می تواند کارکردی مختص به خود یابد. هدف از انجام این پژوهش یافتن تفاوت ها میان ترجمه صفحه و ترجمه صحنه است.. پرسش مطرح شده عبارتست از: بر اساس مدل ارائه شده توسط لدوسر (1995)، تفاوت های ترجمه صفحه و ترجمه صحنه در چیست؟ یافته های این پژوهش حاکی از آن است که ترجمه صفحه به نمایشنامه ا...
