Expression of the c-sis gene and secretion of a platelet-derived growth factor-like protein by simian virus 40-transformed BHK cells. 1985

C Betsholtz, and M Bywater, and B Westermark, and R R Bürk, and C H Heldin

SV40-transformed BHK cells were shown to express two transcripts, of 3.5 kb and 2.0 kb, that hybridised to a human c-sis probe. Antibodies directed against human PDGF specifically recognized a 31 kDa protein in SV40/BHK cell conditioned medium, which upon reduction was split into 16 kDa species. Unfractionated conditioned medium and one of two growth factors isolated from SV40/BHK cells competed with 125I-PDGF for binding to its receptor. The present communication thus provides compelling evidence that an SV40/BHK cell-derived growth factor is a hamster equivalent to human PDGF.

UI	MeSH Term	Description	Entries
D007668	Kidney	Body organ that filters blood for the secretion of URINE and that regulates ion concentrations.	Kidneys
D010982	Platelet-Derived Growth Factor	Mitogenic peptide growth hormone carried in the alpha-granules of platelets. It is released when platelets adhere to traumatized tissues. Connective tissue cells near the traumatized region respond by initiating the process of replication.	Platelet Derived Growth Factor,Factor, Platelet-Derived Growth,Growth Factor, Platelet-Derived
D011956	Receptors, Cell Surface	Cell surface proteins that bind signalling molecules external to the cell with high affinity and convert this extracellular event into one or more intracellular signals that alter the behavior of the target cell (From Alberts, Molecular Biology of the Cell, 2nd ed, pp693-5). Cell surface receptors, unlike enzymes, do not chemically alter their ligands.
