Study showed that FGF19 amplification is a genetic event in Chinese lung squamous cell carcinoma (LSCC) patients, with a frequency of 37.5%. FGF19 amplified LSCC cells express relatively higher levels of FGF19 mRNA expression, and downregulation of FGF19 expression can induce significant cell killing effects in vitro and in vivo.PMID:28906590
