Some antitumour drugs promote the expression of C/EBPα by increasing the production of ROS in tumour cells and releasing the binding of CRT and C/EBPα mRNA.26 We thus speculated whether DADS‐mediated regulation of CRT and C/EBPα involves ROS and whether CRT directly regulates C/EBPα mRNA. Here, CALR is linked to neoplasm.
