In DMS79 cells expression of a GR-eYFP transgene by retroviral infection resulted in increased GR-eYFP protein (Fig. 2a) and apoptosis as evidenced by increased cleaved caspase-3 in the SCLC cells expressing the GR-eYFP (Fig. 2b). The gene discussed is CASP3; the disease is small cell lung carcinoma.
