Increasing evidence shows that aberrant epigenetic regulation of tumor suppressor genes is a contributing factor to their altered expression in esophageal squamous cell carcinoma (ESCC). In the current study, we investigate the role of DOK7 in ESCC cells. We found that enforced expression of DOK7 inhibited the proliferation and invasion of ESCC cells. We also found that treatment of ESCC cells with the DNA methylation inhibitor, 5-aza-2-deoxycytidine (5-azadC), induced the demethylation of DOK7 in promoter and DOK7 expression...

Spinal cord injury (SCI) is damage to the spinal cord that leads to sudden loss of motor and autonomic function and sensory under the level of the injury. The pathophysiological advancement of SCI is divided into two categories: primary injury and secondary injury. Due to the loss of motor, sensory, or cognitive function, a patient's quality of life is likely reduced and places a great burden on society in order to supply health care costs. Therefore, it is important to develop suitable therapeutic strategies for SCI therapy...

The design of compounds 1 and 2 was based on the similar scaffold of pharmacophoric groups for PPARγ and GPR40 agonists. In order to find new compounds with improved biological activity, the current manuscript describes a new dual PPARγ-GPR40 agonist. We synthesized two compounds, which were prepared following a multistep synthetic route, and the relative mRNA expression levels of PPARγ, GLUT4, and GPR40 were quantified in cell culture, as well as insulin secretion and [Ca(2+)] intracellular levels. Compound 1 showed a 7-times increase in the mRNA expression of PPARγ, which in turn enhanced the expression levels of GLUT4 respect to control and pioglitazone...

Osteosarcoma is the most common primary malignancy of the musculoskeletal system, and is associated with excessive proliferation and poor differentiation of osteoblasts. Currently, despite the use of traditional chemotherapy and radiotherapy, no satisfactory and effective agent has been developed to treat the disease. Herein, we found that a flavonoid natural product, galangin, could significantly attenuate human osteosarcoma cells proliferation, without causing obvious cell apoptosis. Moreover, galangin enhanced the expression of osteoblast differentiation markers (collagen type I, alkaline phosphatase, osteocalcin and osteopontin) remarkably and elevated the alkaline phosphatase activity in human osteosarcoma cells...
