GHRL and ovarian cancer: To determine whether ghrelin is a broad-spectrum inhibitor in ovarian cancer, we examined the cell proliferation or cell viability in ovarian cancer cell lines A2780S and its cisplatin resistant subset A2780CP, HUVEC endothelial cells, and mesenchymal cells Gist-T1 and iPSC-MSCs under the treatment of ghrelin or cisplatin.
