JAK1 and gastric cancer: Molecular characterisation of incomplete IM samples did not show pathway enrichment, but multiple overexpressed genes associated with both the colon and GC were detected including HOXA10 and HOXA13. HOXA10 overexpression in GC patients has been linked with poor survival [39] likely through inhibition of apoptosis [40] and activation of JAK1/STAT3 signalling [41].
