FAIM2 and small cell lung carcinoma: As predicted by our CCLE database observations, all 4 SCLC cell lines (H69, H128, H209, and H889) showed highly elevated FAIM2 expression in two different assays detecting exons 2–3 and exons 5–6 in the FAIM2 transcript (Fig. 1B) compared to 8 NSCLC cell lines (p < 0.0001).
