Fhit regulates EMT targets through an EGFR/Src/ERK/Slug signaling axis in human bronchial cells.

Oncogenes and Tumor Suppressors Fhit Regulates EMT Targets through an EGFR/Src/ERK/Slug Signaling Axis in Human Bronchial Cells

In many cancers, including lung carcinomas, Fragile histidine triad (Fhit) is frequently decreased or lost. Fhit status has recently been shown to be associated with elevated in vitro and in vivo invasiveness in lung cancer. Tumor cell invasion is facilitated by epithelial–mesenchymal transition (EMT), a process by which tumor cells lose their epithelial features to acquire a mesenchymal cell-l...

All-trans Retinoic Acid Regulates the Balance of Treg-Th17 Cells through ERK and P38 Signaling Pathway

Autocrine loop for IGF-I receptor signaling in SLUG-mediated epithelial-mesenchymal transition.

Akt, a downstream effector kinase of insulin receptor and insulin-like growth factor-I receptor (IGF-IR), is critically involved in epithelial-mesenchymal transition (EMT). The aim of this study was to assess the impact of SLUG in the IGF/IGF-IR/Akt axis. The SLUG-overexpressing MDCK (SLUG-MDCK) cell clones were used as the EMT model. In contrast to the parental cells and mock-transfected MDCK ...

Cigarette smoke-induced EGFR activation promotes epithelial mesenchymal migration of human retinal pigment epithelial cells through regulation of the FAK-mediated Syk/Src pathway

Epithelial-mesenchymal transition (EMT) of retinal pigment epithelial (RPE) cells is inevitable change of age‑related macular degeneration (AMD). Smoking is a major risk factor for the development of EMT in several diseases, including lung cancer. Cigarette smoke‑induced stress promotes the production of epidermal growth factor (EGF) in RPE cells. However, the underlying signaling pathways indu...

P-111: EGFR, ERK, MEK Genes Expression Level in Cumulus Cells of PCOS Women Compared with Healthy Women

Background Poly cystic ovarian syndrome (PCOS) is known as a common endocrine disorder in women at reproductive ages and may cause developmental abnormality in oocyte. ERK has found as a regulator protein of Gap junctions (GJ) function and the level of exchanges between two neighbors cells, for example oocyte and surrounding cumulus cells (CCs) in the mammalian ovary. Such exchange is essential...
