Indeed, the upregulation of profibrotic proteins in LC and HCC patients that belong to the ECM (HSPG2, LUM, FBLN1, TNXB, TNC, and EFEMP1), inflammation (IL3, CXCL14, CCL21, BMP2, BMP4, OSM, and TIMP1), and angiogenesis (VWF, ANGPT1, protein C receptor [PROCR]) has been previously reported (61, 62, 63, 64). Here, IL3 is linked to laryngotracheoesophageal cleft.
