SKIL and lung cancer: Screening of SKIL expression levels in lung cancer cell lines showed that SKIL mRNA expression was elevated in some of LUAD cell lines (NCI-H1975 and CALU-3) and LUSC cell lines (NCI-H520 and NCI-H226), compared to normal lung cell line (16HBE), while SKIL level was not elevated in HCC827, A549, and SK-MES-1 cell lines (Fig. 1g).
