The platelet-derived growth factor alpha-receptor is encoded by a growth-arrest-specific (gas) gene.
Using the Escherichia coli lacZ gene to identify chromosomal loci that are transcriptionally active during growth arrest of NIH 3T3 fibroblasts, we found that an mRNA expressed preferentially in serum-deprived cells specifies the previously characterized alpha-receptor (alphaR) for platelet-derived growth factor (PDGF), which mediates mitogenic responsiveness to all PDGF isoforms. Both PDGFalph...
متن کاملA myelin protein is encoded by the homologue of a growth arrest-specific gene.
Striking features of the cellular response to sciatic nerve injury are the proliferation of Schwann cells in the distal nerve stump and the downregulation of myelin-specific gene expression. Once the axons regrow, the Schwann cells differentiate again to reform the myelin sheaths. We have isolated a rat cDNA, SR13, which is strongly downregulated in the initial phase after sciatic nerve injury....
متن کاملAuxin is a positive regulator for ethylene-mediated response in the growth of Arabidopsis roots.
The requirement of auxin for the ethylene-mediated growth response in the root of Arabidopsis thaliana seedlings was investigated using two ethylene-resistant mutants, aux1-7 and eir1-1, whose roots have been shown to have a defect in the auxin influx and efflux carriers, respectively. A 50% inhibition of growth (I(50)) was achieved with 0.84 microl liter(-1) ethylene in wild-type roots, but 71...
متن کاملGrowth arrest specific 1 (GAS1) is abundantly expressed in the adult mouse central nervous system.
Growth arrest specific 1 (GAS1) is a pleiotropic protein that induces apoptosis and cell arrest in different tumors, but it is also involved in the development of the nervous system and other tissues and organs. This dual ability is likely caused by its capacity to interact both by inhibiting the intracellular signaling cascade induced by glial cell-line derived neurotrophic factor and by facil...
متن کاملGrowth arrest in human T-cells is controlled by the non-coding RNA growth-arrest-specific transcript 5 (GAS5).
The control of growth of lymphocyte populations is crucial to the physiological regulation of the immune system, and to the prevention of both leukaemic and autoimmune disease. This control is mediated through modulation of the cell cycle and regulation of cell death. During log-phase growth the rate of proliferation is high and there is a low rate of cell death. As the population density incre...
