KHSRP and esophageal squamous cell carcinoma: In ESCC cell lines, increased expression of the KHSRP protein compared with normal esophagus was more prominently observed than that of the KHSRP mRNA, suggesting that undiscovered mechanisms causing hyperinduction of the KHSRP protein, such as enhanced translation and protein stabilization, contribute to overexpression and activation of oncogenic KHSRP in ESCC.
