Ectopic Expression of E2F1 Stimulates β-Cell Proliferation and Function
OBJECTIVE Generating functional beta-cells by inducing their proliferation may provide new perspectives for cell therapy in diabetes. Transcription factor E2F1 controls G(1)- to S-phase transition during the cycling of many cell types and is required for pancreatic beta-cell growth and function. However, the consequences of overexpression of E2F1 in beta-cells are unknown. RESEARCH DESIGN AND...
متن کاملP-185: Expression and Function of Vascular Endothelial Growth Factor in Fallopian Tuben Carrying Ectopic Pregnancy
Background: Vascular endothelial growth factor (VEGF) is an angiogenic growth factor that is produced by different tissues, including the endometrium and ovary. VEGF is involved in many processes related to reproductive physiology, including angiogenesis, which is essential for implantation and placentation. It has been suggested that VEGF may be the angiogenic factor responsible for the implan...
متن کاملE2F1-Mediated Upregulation of p19INK4d Determines Its Periodic Expression during Cell Cycle and Regulates Cellular Proliferation
BACKGROUND A central aspect of development and disease is the control of cell proliferation through regulation of the mitotic cycle. Cell cycle progression and directionality requires an appropriate balance of positive and negative regulators whose expression must fluctuate in a coordinated manner. p19INK4d, a member of the INK4 family of CDK inhibitors, has a unique feature that distinguishes ...
متن کاملAn E2F1-dependent gene expression program that determines the balance between proliferation and cell death.
The Rb/E2F pathway regulates the expression of genes essential for cell proliferation but that also trigger apoptosis. During normal proliferation, PI3K/Akt signaling blocks E2F1-induced apoptosis, thus serving to balance proliferation and death. We now identify a subset of E2F1 target genes that are specifically repressed by PI3K/Akt signaling, thus distinguishing the E2F1 proliferative or apo...
متن کاملLowered Expression of Tumor Suppressor Candidate MYO1C Stimulates Cell Proliferation, Suppresses Cell Adhesion and Activates AKT
Myosin-1C (MYO1C) is a tumor suppressor candidate located in a region of recurrent losses distal to TP53. Myo1c can tightly and specifically bind to PIP2, the substrate of Phosphoinositide 3-kinase (PI3K), and to Rictor, suggesting a role for MYO1C in the PI3K pathway. This study was designed to examine MYO1C expression status in a panel of well-stratified endometrial carcinomas as well as to a...
