Globally, ovarian cancer is the 2nd most frequent cause of gynecologic-associated cancer fatalities among women. It has an unfavorable prognosis. There is a need to elucidate on the mechanisms involved in ovarian cancer progression and to identify novel cancer targets. We investigated and verified AHNAK contents in ovarian cancer tissues and corresponding healthy tissues. Then, we overexpressed AHNAK in vitro and in vivo to establish the roles of AHNAK in ovarian cancer cell proliferation and metastasis. Finally, we evaluated the possible molecular mechanisms underlying. We established that AHNAK was downregulated in ovarian cancer. Elevated AHNAK contents in ovarian cancer cell lines remarkably repressed ovarian cancer cell growth, along with metastasis in vitro, as well as in vivo. Moreover, AHNAK suppressed the progress of ovarian cancer partly via dampening the Canonical Wnt cascade. Therefore, AHNAK may be a biomarker and treatment target for ovarian cancer.
