FOXG1 and gastric cancer: Multiple human forkhead box protein homologs (yFKH2/hFOXJ1/FOXG1/FOXJ3/FOXH1) (Figure 6D) were observed as UES in PharmacoDB, of which FOXJ1 underexpression is a marker of poor prognosis in gastric cancer [133], reduced expression of FOXG1 is correlated with worse prognosis in breast cancer [134], FOXJ3 is inhibited by miR-517a and associated with lung and colorectal cancer cell proliferation and invasion [135,136], and FOXH1 is overexpressed in breast cancer and FOXH1 inhibition reduces proliferation in breast cancer cell lines [137].
