IL-6 has also been shown to promote angiogenesis via VEGF secretion by human peritoneal mesothelial cells, in the context of trans signalling (i.e., simultaneous exposure to IL-6 and sIL6-Rα) [92], as well as in the context of tumor stromal fibroblast-secreted IL-6 acting in an autocrine fashion to drive VEGF expression in colorectal cancers [93]. The gene discussed is VEGFA; the disease is colorectal cancer.
