Abstract 1821: Conessine inhibits cell proliferation, migration and invasion, and induces apoptosis in liver cancer cells

Abstract

Abstract Cancer-related deaths from hepatocellular carcinoma (HCC) rank first worldwide. Although many attempts have been made to treat HCC, the survival rate remains unsatisfactory. Many plants from the family Apocynaceae, such as Holarrhena floribunda, contain conessine, a steroidal alkaloid. Several studies have indicated that conessine acts as an antihistamine with cancer therapy and antimicrobial resistance, but it hasn't been tested for its anti-cancer activity against liver cancer. Our study aimed to investigate the anticancer properties of conessine against liver cancer. We tested the effects of conessine on cell proliferation, migration, invasion, and epithelial-mesenchymal transition (EMT) markers using both Huh7 and Mahlavu cells. Our experimental results indicated that conessine inhibited cell proliferation, migration, motility, and invasion in Huh7 and Mahlavu cells. Results of Western blot analysis showed that conessine induced apoptosis and EMT in liver cancer cells. Taken together, our results demonstrated that conessine exhibits anticancer activity in liver cancer through suppressing cell proliferation, migration, and invasion, and inducing apoptosis, suggesting it may have benefits for liver cancer treatment.
