Cell Line Description:
NCI-H526 expresses elevated levels of 2 biochemical markers of SCLC: neuron specific enolase and the brain isoenzyme of creatine kinase. They do not express L-dopa carboxylase or bombesin-like immunoreactivity. These cells express the c-kit gene as well as the N-myc gene, but not c-myc or L-myc. N-myc is amplified and p75 c-myb expression was observed. NCI-H526 also expresses the proto-oncogenes N-ras, Ki-ras, Ha-ras, and c-raf1. Only trace amounts of the retinoblastoma susceptibility gene, RB mRNA were detected. RB protein was not detected. The cells express easily detectable levels of p53 mRNA compared to levels found in normal lung; abnormally sized mRNA was present.
