Nitric oxide inhibits enterocyte migration through activation of RhoA-GTPase in a SHP-2-dependent manner.
Diseases of intestinal inflammation like necrotizing enterocolitis (NEC) are associated with impaired epithelial barrier integrity and the sustained release of intestinal nitric oxide (NO). NO modifies the cytoskeletal regulator RhoA-GTPase, suggesting that NO could affect barrier healing by inhibiting intestinal restitution. We now hypothesize that NO inhibits enterocyte migration through RhoA...
متن کاملBlocking TGF-β inhibits breast cancer cell invasiveness via ERK/S100A4 signal.
OBJECTIVE Targeted down-regulation of TGF-β expression inhibits invasion and metastasis in breast cancer cells. However, the mechanism that TGF-β functions by remains largely unknown. In the present study we report the mechanism of ERK1/2 dependant S100A4 regulation by TGF-β and its possible role in TGF-β-mediated tumour invasion in vitro. MATERIALS AND METHODS Small interfering RNA targeting...
متن کاملDvl2-Dependent Activation of Daam1 and RhoA Regulates Wnt5a-Induced Breast Cancer Cell Migration
BACKGROUND The Dishevelled (Dvl) and Dishevelled-associated activator of morphogenesis 1 (Daam1) pathway triggered by Wnt5a regulates cellular polarity during development and tissue homoeostasis. However, Wnt5a signaling in breast cancer progression remains poorly defined. METHODOLOGY/PRINCIPAL FINDINGS We showed here that Wnt5a activated Dvl2, Daam1 and RhoA, and promoted migration of breast...
متن کاملEphA receptors regulate prostate cancer cell dissemination through Vav2–RhoA mediated cell–cell repulsion
Metastatic prostate cancer cells display EphB receptor-mediated attraction when they contact stromal fibroblasts but EphA-driven repulsion when they contact one another. The impact of these 'social' interactions between cells during cancer cell invasion and the signalling mechanisms downstream of Eph receptors are unclear. Here we show that EphA receptors regulate prostate cancer cell dissemina...
متن کاملD4-GDI, a Rho GTPase regulator, promotes breast cancer cell invasiveness.
D4-GDI is a Rho GDP dissociation inhibitor that is widely expressed in hematopoietic cells. Its possible expression and function in breast cancer cells has not been described. Here, we found that D4-GDI is expressed in a panel of breast cancer cell lines, but not in benign-derived mammary epithelial cells. Knockdown of D4-GDI expression in MDA-MB-231 cells by RNA interference blocks cell motili...
