Overexpression of NFIB is oncogenic in RP mice and some SCLC cell lines, and it promotes metastasis to the liver and other organs (Dooley et al, 2011; Denny et al, 2016; Semenova et al, 2016; Wu et al, 2016; Böttger et al, 2019). The gene discussed is NFIB; the disease is small cell lung carcinoma.
