The expression and activation of the nonreceptor tyrosine kinase Src, which also affects integrin‐mediated signaling and is linked to enhanced tumor cell growth, metastasis, and survival [22, 23, 39, 40, 41], was up to ~ 2‐fold increased in TMD‐GpA‐I expressers over TMD‐αvβ3 and TMD‐GpA transfectants, after a flotation period of 48 h in ascites (Fig. 7C,D). The gene discussed is GYPA; the disease is neoplasm.
