Title: Therapeutic agent of liver cancer with activated FGF19-FGFR4 signaling pathway and a method for screening thereof
Inventor: AHN SUNG MIN
IPC: G01N33/50
Filed: 2021-03-05
Abstract: The present invention relates to a screening method for a therapeutic agent for liver cancer with an FGF19-FGFR4 signal pathway activated. In liver cancer cells with an FGF19-FGFR4 signaling pathway activated, Src forms an endosome signaling complex with FGFR4, STAT3, and EEA1 and induces endosome delivery of the complex to promote formation of liver cancer, thus inhibition of the Src is confirmed to suppress formation of the endosome signaling complex, thereby inhibiting activation of the FGF19-FGFR4 signaling pathway to suppress development of liver cancer. Furthermore, by proving that cytotoxicity of an Src inhibitor is more excellent than cytotoxicity of an FGFR4 inhibitor, the Src inhibitor is confirmed to be used as a therapeutic agent for liver cancer with an FGF19-FGFR4 signaling pathway activated. Therefore, the screening method for a therapeutic agent for liver cancer with an FGF19-FGFR4 signaling pathway activated using an Src protein was established. The screening method comprises the following steps of: treating liver cancer cells with test substances; measuring a binding level of FGFR4, Src, STAT3, and EEA1 proteins; and selecting test substances that are reduced compared to a control group.
