Melatonin has been reported to protect intervertebral discs (IVDs) from degeneration and to exert a potential anti-angiogenic effect. The aim of the present study was to investigate the anti-angiogenic and anabolic effects of melatonin in IVDs. Human nucleus pulposus (NP) and degenerative nucleus pulposus (DNP) cells were isolated and treated with melatonin. The results indicated that melatonin promoted ECM synthesis and NP cell proliferation. In addition, an NP/DNP and human umbilical vein endothelial cell (HUVEC) co-culture model was used to investigate the anti-angiogenesis effect of melatonin. Melatonin was indicated to suppress tube formation and migration of HUVECs in culture with NP cell-conditioned medium, as well as in an NP cell co-culture model. Fluorescence-labeled vascular endothelial growth factor (VEGF) was used to study the binding between VEGF and its receptor. The results of the present study indicated that melatonin exerts an angiogenic effect via inhibition of the binding of VEGF to its receptor in HUVECs. Taken together, these results suggest that melatonin is a potential agent to prevent IDD.The present study aimed to investigate the changes in miRNA-142 and bone morphogenetic protein-2 (BMP-2) expression before and after hip replacement surgery, and to determine their association with receptor activator of NF-κB ligand (RANKL) and osteoprotegerin (OPG). For this purpose, 142 cases of hip arthroplasty in patients with femoral neck fracture were selected as the research group, and 50 cases of healthy individuals who underwent a physical examination during the same time period were selected the control group. Serum miR-142 and BMP-2 le
