Abstract:
Gastric cancer is the fourth most common malignancy world-wide that bears a high mortality by invasiveness and metastases. To this end, we examined the role of miR-1 in mobility and migration of gastric cancer cells. miR-1 was down-regulated and Sorcin, which supports invasion, was highly expressed in gastric cancer cell lines as compared to the control. The overexpression of miR-1 significantly inhibited the mobility and migration of gastric cancer cells, while, its knockdown exerted an oppoiste effect. In addition, while overexpression of miR-1 suppressed the expression of Sorcin, the siRNA knockdown of Sorcin significantly counteracted the effect of miR-1 inhibitor on cell invasion and migration of gastric cancer cells. A miR-1 mimic decreased while its inhibitor increased the MMP-7 and VEGF required for invasion. Taken together, the findings support the view that miR-1 controls the mobility and migration of gastric cancer cells and might be a therapeutic target for blocking gastric cancer invasion.

Role of Myosin in Cell Migration
Myosin II is a hexamer comprising two heavy chains with globular heads and coiled-coil tails, two regulatory light chains, and two essential light chains. The ATPase sites on the myosin heads hydrolyze ATP, and the released phosphate generates the force for contraction....
