The effects of the histone deacetylase inhibitor PXD-101 on human osteosarcoma cells were investigated. The study found that PXD-101 inhibited cell proliferation, induced apoptosis, and inhibited cell migration. This study suggests that PXD-101 may be a potential new therapeutic approach for osteosarcoma patients.
The therapeutic strategies for osteosarcoma involve both surgical approach and chemotherapy, but the identification of new therapeutic targets is particularly necessary in patients with local chemo-resistance, recurrence and lung metastases. The role of epigenetic regulation in osteosarcoma is largely unknown. Thus, in this study we disclosed the effects of histone deacetylase inhibitor drug PXD-101 on human osteosarcoma (OS) cell lines with different aggressiveness, including Saos-2, HOS and 143B cell lines. XTT assays revealed that treatment of Saos-2, HOS and 143B cells with PXD-101 decreased cell viability in a concentration-dependent manner. Fluorescenceactivated cell sorting (FACS) analysis showed that PXD-101 inhibited proliferation and induced cell apoptosis. Wound healing assay indicated that PXD-101 inhibited migration of osteosarcoma cells. Real-Time RT-qPCR and protein analysis highlighted reduced expression of Runx2, Osterix and Mad2, probably due to Cyclin B1 inhibition by PXD-101 treatment. To our knowledge, this is the first study that characterized the anti-tumoral effect of PXD-101 in OS cells, suggesting a potential new therapeutic approach in osteosarcoma patients.
