Additionally, we analysed the correlation between IL-6 levels and that of several adipocyte surrogate genes in PAAD and found IL-6 correlated with adipoQ, FABP4, HSL, LPL, and PLIN1, but not with CEBP and PPAR gamma based on GEPIA2 (Supplementary Figure S2). Here, ADIPOQ is linked to pancreatic adenocarcinoma.
