IL17RB and gastric cancer: Classification analysis shows that the molecular functions of the up- and downregulated proteins differ in transducer activity, as a result of highly expressed in GC: receptor-type tyrosine-protein kinase (FLT3); interleukin-17 receptor B (IL17RB); lithostathine-1-β (REG1B); vascular endothelial growth factor receptor 1 (FLT1); and glycine receptor subunit α-3 (GLRA3) (Supplementary Figure S11), all of which are associated with cancer, and specifically GC [22,23,24,25,26].
