Growth factor control of skeletal muscle differentiation: commitment to terminal differentiation occurs in G1 phase and is repressed by fibroblast growth factor
Analysis of MM14 mouse myoblasts demonstrates that terminal differentiation is repressed by pure preparations of both acidic and basic fibroblast growth factor (FGF). Basic FGF is approximately 30-fold more potent than acidic FGF and it exhibits half maximal activity in clonal assays at 0.03 ng/ml (2 pM). FGF repression occurs only during the G1 phase of the cell cycle by a mechanism that appea...
متن کاملCell surface fibroblast growth factor and epidermal growth factor receptors are permanently lost during skeletal muscle terminal differentiation in culture
One characteristic of skeletal muscle differentiation is the conversion of proliferating cells to a population that is irreversibly postmitotic. This developmental change can be induced in vitro by depriving the cultures of specific mitogens such as fibroblast growth factor (FGF). Analysis of cell surface FGF receptor (FGFR) in several adult mouse muscle cell lines and epidermal growth factor r...
متن کاملSimultaneous Presence of G1 and G4 Mutations in Growth Differentiation Factor 9 Gene of Iranian Sheep
The fecundity in sheep has been much interested for producers due to its economical importance. Growth differentiation factor 9 (GDF9) is an autosomal gene with over dominance effect for twosingle nucleotide polymorphisms(SNPs), which resulted in sterility in homozygote mutant ewes and additive effect for three SNPs, without showing sterility event. In the present study, DNA was extracted from ...
متن کاملControl of myogenic differentiation by fibroblast growth factor is mediated by position in the G1 phase of the cell cycle
We have used the expression of the muscle form of creatine phosphokinase (M-CPK) to assay myogenic differentiation in the cloned muscle cell line BC3Hl. BC3Hl cells express M-CPK when arrested in the G0 portion of the cell cycle. Addition of the anionic form of brain fibroblast growth factor (B-FGF) rapidly represses synthesis of M-CPK with a half-time of 7 h. Even though B-FGF is not mitogenic...
متن کاملControl by Fibroblast Growth Factor of Differentiation in the BCgH
The regulation of creatine phosphokinase (CPK) expression by polypeptide growth factors has been examined in the clonal mouse muscle BC3H1 cell line. After arrest of cell growth by exposure to low concentrations of serum, BC3H1 cells accumulate high levels of muscle-specific proteins including CPK. The induction of this enzyme is reversible in the presence of high concentrations of fetal calf s...
