DNA from 10T1/2 cells transformed by activated neutrophils was analyzed for restriction length polymorphisms (RFLPs) in cellular homologues of retroviral oncogenes, and consistent RFLPs were found in MspI sites of the c-abl gene of all PMN-transformed cell lines. MspI digests probed with c-myc, v-Ki-ras, v-Ha-ras or v-mos showed no RFLPs, and none were observed in EcoRI, PstI, HindIII, BamHI, SmaI, Sau3a, MboI, HhaI, or TaqI digests probed with v-abl. Analysis of HpaII digests supports the conclusion that c-abl RFLPs result from differential methylation of the CCGG HpaII/MspI recognition sequence. MspI RFLPs in the c-abl gene may provide markers for oxidant-related genetic injury.
