To pinpoint whether the inhibitory effect of DSF on YAP inactivation is dependent on the STRIPAK-Hippo signaling or on the Src–YAP axis in GC, we examined DSF-induced YAP phosphorylation by using antibodies which specifically recognize phosphorylated serine (pSer) or phosphorylated tyrosine (pTyr). The gene discussed is SRC; the disease is gastric cancer.
