Objective To investigate the inhibitory effect of genistein on the invasion of ovarian carcinoma cell line SKOV 3 in vivo and in vitro. Methods The abilities of the genistein-treated SKOV 3 cells to invade through reconstituted matrigel in transwell chambers were investigated in vitro and the invasion effect in vivo was determined using the xenograft models of SKOV 3 in nude mice. Results The ability of the 20 ?mol/L genistein-treated cells to invade the reconstituted basement membrane was decreased significantly at 72 h. This inhibition was in a dose-dependent manner. Genistein at the dose of 40 ?mol/L had the strongest effect. The results in vivo suggested that the grade of invasion in control SKOV 3 cells was in a time-dependent manner and genistein-treated group could apparently inhibit the progress of invasion, localizing the tumor in invasion grade 0 or grade I, and decreasing the proportion of grades Ⅱ, Ⅲ, Ⅳ. Conclusion The results suggest that genistein has inhibitory effect on the invasion of human ovarian carcinoma cell lines SKOV 3 in vivo and in vitro.

BACKGROUND:In the whole world, spinal cord injuries caused by trauma lead to more than 180 000 people presenting with permanent impairment annualy. A large number of experiments have confirmed in recent years, under physiological conditions, microRNA has specific expression and plays an important role in the nervous system. OBJECTIVE: To discuss the changes in microRNA expression induced by injuries as wel as the pathophysiological significance in spinal cord injury, and to explore the development potential of microRNA in tissue-engineered and clinical repair of spinal cord injury. METHODS:A computer-based search of PubMed and Chinese Journal Database was performed for related articles published from January 2000 to December 2014 using the keywords of “SCI, microRNA, transcriptional control, clinical research progress” in English and Chinese. Finaly, 38 articles were included for result analysis. RESULTS AND CONCLUSION: Mechanical injury initialy triggers a series of complex secondary damages, including nervous, vascular and immune systems, which can influence the severity of spinal cord injury to a great extent. Secondary damage to the spinal cord is mainly attributed to the activation and deactivation of some specific genes associated with celular and biochemical mechanisms, such as cysteine aspartate specific protease (caspase) gene family, apoptosis related protein Fas and its ligand Fasl system, P53 gene, apoptosis related gene Bcl-2 family. Recent studies have proved that the functional activation of microRNA expression is the key to spinal cord injury. With the development of biological information engineering, studies and controling technologies associated with microRNA expression have been gradualy dominated, some clinical application based on microRNA technology has entered the clinical trial stage. It is believed that with the continuous development of technology and decrease of cost, permanent dysfunction due to spinal cord injury can be regulated and repaired through the microRNA technology at gene level in the future.
