Alternatively spliced platelet-derived growth factor A-chain transcripts are not tumor specific but encode normal cellular proteins
Abstract
Two platelet-derived growth factor A-chain proteins, termed short and long A chains, are generated as a result of alternative mRNA splicing of exon 6 of the A-chain gene. S1 nuclease mapping and polymerase chain reaction analyses demonstrate that both short and long A-chain transcripts are expressed in a variety of normal tissues. In addition, immunohistochemical localization of long A-chain protein reveals a cellular distribution identical to that observed with platelet-derived growth factor heteroserum.
