As a note, we used a highly specific and low‐background anti‐PLXDC2 rabbit antibody (clone 4G3) [41], which allowed us to specifically detect PLXDC2 expression in the tumor area of PDAC, as well as in HCC and colorectal cancers in our previous studies [30, 31]. Here, PLXDC2 is linked to hepatocellular carcinoma.
