Wu et al. (2019) described the same overexpression of RPSA in PDAC tissues by using different antibodies. Interestingly, we previously showed a similar overexpression of TRPM7 in PDAC primary tumor (Rybarczyk et al., 2012) as well as in lymph node (Rybarczyk et al., 2017). Here, RPSA is linked to neoplasm.
