Expression of mRNA for GRPR and EGFR in samples of DMS-153 SCLC. PCRs yielded products the size of 159 bp for GRPR, 400 bp for EGFR, and 459 bp for β-actin. Lane M, 100-bp DNA molecular mass marker; lanes 1-5, untreated animals; lanes 6-9, animals treated with RC-3940-II; lanes 10-12, animals treated with RC-3940-II + JV-1-65.
