ABSTRACT Natural compounds have emerged as an approach in cancer therapy. Pulsatilla koreana Nakai is used as a traditional medicinal plant that found throughout China and Korea. However, anti-cancer effects of Hederoside C (HedC) isolated from P. koreana has not been investigated in osteosarcoma. The present study aimed to demonstrate anti-cancer functions of HedC against human osteosarcoma cells. Herein, we found that HedC suppressed the proliferation of MG63 cells and U2OS cells in the dose- and time-dependent manner, and caused intrinsic apoptosis pathways as evidenced by morphological changes, TUNEL-positive cells, cleaved-PARP, and cleaved-caspase 9 and 3. HedC increased p53, Bax, and p21, whereas HedC reduced Bcl-2. HedC-mediated apoptosis was accompanied by decreases in the mitogen-activated protein kinases (MAPKs) and STAT3 phosphorylation. Wound hea ling and Boyden chamber assays also showed the anti-metastatic effects of HedC by suppressing migration and invasion. In addition, the anti-cancer effects of HedC were observed in in vivo xenograft mice model, and HedC treatment induced the decreased PCNA and p-STAT3 as well as the increased p53 and cleaved caspase-3. Taken together, our results provide evidence that HedC might be an attractive therapeutic strategy against osteosarcoma. PMID:34659904 | PMC:PMC8493407 View on the web Inoreader.
