Lack of early diagnostic biomarkers is one of the major reasons for the delayed diagnosis and poor prognosis of patients with OvCa (15).As an oncogene or tumor suppressor gene, lncRNA could serve as a potential diagnostic and prognostic biomarker and therapeutic target in several cancers, including OvCa (16, 17).Based on the database search, lncRNA ZFHX4-AS1 was perceived to be highly expressed in OvCa. The gene discussed is ZFHX4; the disease is cancer.
