FOXQ1 and non-small cell lung carcinoma: Further studies are warranted to elucidate the mechanisms involved in FoxQ1-mediated NSCLC tumorigenesis, and explore the effect of RNA/lentivirus-mediated FoxQ1-silencing on NSCLC growth in animal models and the diagnostic value of FoxQ1 protein in serum in a large cohort of NSCLC patients.
