摘要： The function of Vasohibin-1 (VASH1) in human cancer has not been thoroughly or comprehensively examined. Here, we identified the tumor suppressor part of VASH1 across cancers, including epithelial ovarian tumors. Our study carefully contrasted the expression of VASH1 in pancancer and nontumorous tissues in a public database to explore its regulatory role in clinical prognosis, diagnosis, tumor purity, and immune cell infiltration. Next, we explored the antitumor mechanism of VASH1 through drug sensitivity, functional enrichment, and phenotypic experiments in ovarian cancer. Research suggests that the expression of VASH1 in neoplastic tissues is lower than that in normal tissues. VASH1 affects the OS and RFS of several tumor types. In addition, VASH1 expression resulted in a high OS and RFS in the diagnosis of tumor and nontumor tissues and negatively regulated tumor purity. Moreover, VASH1 controls the tumor microenvironment by regulating immunocyte infiltration. In ovarian cancer, VASH1 can serve as a biomarker to estimate the efficacy of chemotherapy. Functional enrichment analysis suggests that VASH1 plays a tumor suppressor role by regulating the extracellular matrix receptor pathway. VASH1 inhibition of the malignant phenotype of ovarian cancer cells was further confirmed by in vivo experiments. These results indicate that VASH1 acts as a cancer-inhibiting factor and potential therapeutic target in ovarian cancer.
