In summary, our study reported the inhibitory effect of CA on the proliferation and invasion, growth, and metastasis of human epithelial ovarian cancer cells in vitro and in vivo, and this effect may be related to CA reversing the EMT process and inhibiting the proliferation and migration of ovarian cancer cells by downregulating the PI3K/AKT signaling pathway. The gene discussed is AKT1; the disease is ovarian cancer.
