TP53 and mesothelioma: Forced cytoplasmic HuR expression in mesothelioma cell lines increased chemotherapy resistance through increased expression of CALB2, upregulation of the E2F pathway and suppression of the p53 pathway.<h4>Conclusions</h4>Cytoplasmic HuR expression increases the chemoresistance and postoperative recurrence risk of pleural mesothelioma, making it a potential biomarker for predicting therapeutic prognosis.
