LSD1 was reported to be involved in the development of ovarian cancer.[28] However, the association between FOXP4-AS1 lncRNA and ovarian cancer has rarely been reported.[29] Therefore, our aim in this study was to elucidate the expression of FOXP4-AS1 in ovarian cancer tissues and the potential therapeutic and prognostic value of this lncRNA. The gene discussed is KDM1A; the disease is ovarian carcinoma.
