Basic fibroblast growth factor induces cell migration and proliferation after glia-specific gene transfer in mice.
Basic fibroblast growth factor (bFGF) is overexpressed in most high-grade human gliomas, implying that it is involved in the pathogenesis of these tumors. To assess the biological effect of inappropriate production of bFGF in normal astrocytes, we developed a system for glia-specific gene transfer in transgenic mice. A transgene encoding the receptor for subgroup A avian leukosis virus and cont...
متن کاملThe Rho protein exchange factor Vav3 regulates vascular smooth muscle cell proliferation and migration.
AIMS Rho guanine nucleotide exchange factors (Rho GEFs) are responsible for Rho protein activation by catalyzing the exchange of GDP for GTP. Although overactivation of Rho proteins is a common component of the pathogenesis of vascular disorders, the molecular mechanisms and the Rho GEFs regulating Rho protein activity and Rho-dependent functions in vascular smooth muscle cells (VSMC) are still...
متن کاملPhoenix dactylifera L. Fruit Induces Cell Proliferation of A2780, A172 and HFFF2 Cell Lines
Dates fruit has been used as staple food in the Middle East for thousands of years and various types of dates are found worldwide. Dates and their constituents show various roles in diseases prevention and treatment through anti-oxidant, anti-inflammatory, anti-bacterial activity. In the present study we investigated the activity of aqueous and n-hexane extracts of Phoenix dactylifera L. fruit ...
متن کاملMiR-6165 Dysregulation in Breast Cancer and Its Effect on Cell Proliferation and Migration
Background: ncRNAs have been identified as oncogenic drivers and tumor suppressors in any type of cancer. Although many classes of ncRNAs have been reported, most studies have been performed on microRNAs (miRNAs). miRNAs can regulate several target genes and affect important processes such as homeostasis, angiogenesis, cell proliferation, differentiation, and apoptosis. Located in the p75NTR ge...
متن کاملGEFT, a Rho family guanine nucleotide exchange factor, regulates neurite outgrowth and dendritic spine formation.
The Rho family of small GTPases controls a wide range of cellular processes in eukaryotic cells, such as normal cell growth, proliferation, differentiation, gene regulation, actin cytoskeletal organization, cell fate determination, and neurite outgrowth. The activation of Rho-GTPases requires the exchange of GDP for GTP, a process catalyzed by the Dbl family of guanine nucleotide exchange facto...
