As a result, FOXA1 may affect the similar molecular mechanisms to CDKN2C in SCLC (Additional file 5), such as neuronal cell body (cell component), cell cycle G1/S phase transition (biological process), chromatin DNA binding (molecular function), cell cycle, and human T-cell leukemia virus 1 infection (signaling pathways) (Fig. 4F). This evidence concerns the gene FOXA1 and small cell lung carcinoma.
