Therefore, the high expression of HuR in tumor cells compared with normal cells suggests that it plays a key role in tumor progression, and cytoplasmic HuR accumulation in malignant tumors (including pancreatic cancer, lung cancer, gallbladder cancer, and urothelial cancer) is related to poor prognosis [14–17]. This evidence concerns the gene ELAVL1 and familial pancreatic carcinoma.
