FAM215A and esophageal cancer: Furthermore, the up-regulation of Snail can significantly attenuate the G1 block of esophageal cancer cells caused by the down-regulation of HuR (Figure 6D).As well as up-regulation of Snail also significantly decreased the apoptosis rate of esophageal cancer cells caused by X-rays, and at the same time affected the expressions of apoptosis-related proteins in esophageal cancer (Figure 6E).
