""Transforming growth factor (TGF)-�� and activin, members of TGF-�� superfamily, are abundantly expressed in the endometrium and regulate decidualization of endometrial stroma. Smad2 and Smad3 are receptor-regulated Smads (R-Smads) that transduce extracellular TGF-��/activin/Nodal signaling. In situ hybridization results showed that Smad3 was highly expressed in the decidual zone during the peri-implantation period in mice. By using artificial decidualization, we found that Smad3 null mice showed partially compromised decidualization. We therefore hypothesized that Smad2 might http://www.selleckchem.com/products/PD-0325901.html compensate for the function of Smad3 during the process of decidualization. Smad2 was also highly expressed in the decidual zone and phosphorylated Smad2 was much more abundantly increased in the deciduoma of Smad3 null mice than for wild-type (WT) mice. We further employed an in vitro uterine stromal cell decidualization model, and found that decidual prolactin-related protein (dPRP) and cyclin D3, which are well-known markers for decidual cells, were significantly down-regulated in Smad3 null decidual cells, and were much more significantly reduced when the expression of Smad2 was simultaneously silenced by its siRNA (P? http://www.selleck.cn/products/JNJ-26481585.html scaffolding protein. We have found that co-expression of PTEN and hDlg enhanced the negative regulation of the PI3K/Akt pathway by PTEN, indicating the physiologic importance of these interactions. APC and PTEN share other PDZ domain containing�Cinteracting partners, including the MAGI scaffolding proteins and the MAST family of protein kinases. Mutational analysis revealed that the C-terminal PDZ-binding motifs from APC and PTEN were differentially recognized by distinct PDZ domains. APC bound to the three PDZ domains from hDlg, whereas PTEN mainly bound to PDZ-2/hDlg. This indicates the existence of overlapping, but distinct PDZ-domain recognition patterns by APC and PTEN. Furthermore, a ternary complex formed by APC, PTEN, and hDlg was detected, suggesting that hDlg may serve as a platform to bring in proximity APC and PTEN tumor suppressor activities.
