MicroRNA-545-5p regulates apoptosis, migration and invasion of osteosarcoma by targeting dimethyladenosine transferase 1.

The metastasis of osteosarcoma is a major threat to both adolescents and young adults. Identifying novel targets that may prevent osteosarcoma metastasis is critical in developing advanced clinical therapies for treating this cancer. The present study aimed to explore the mechanism of microRNA (miR)-545-5p in the metastasis of osteosarcoma.

LncRNA-zinc finger protein 281 downregulates rho-associated coiled-coil containing protein kinase 1 by upregulating miR-144 in osteosarcoma.

Zinc finger protein 281 (ZNF281) has been characterized as a tumor suppressive lncRNA in glioma. The present study aimed to analyze the functionality of ZNF281 in osteosarcoma (OS). It was demonstrated that ZNF281 was downregulated in OS tissue specimens and predicted the survival of patients with OS.

Curcumin inhibits hypoxia-induced proliferation and invasion of MG-63 osteosarcoma cells via downregulating Notch1.

Curcumin is a biologically active ingredient abundantly present in the ground rhizomes of Curcuma longa with a wide range of bioactive properties, including antitumor effects. Hypoxia is a common characteristic of solid tumors, including osteosarcoma. However, whether curcumin has antitumor effects on osteosarcoma under hypoxic conditions, and its underlying molecular mechanisms, remain unclear.
