体外研究
(In Vitro) | BLU9931 inhibits proliferation of HCC cell lines that express an intact FGFR4 signaling complex, withEC50s of 0.07 μM, 0.11 μM and 0.02 μM for Hep 3B, HuH7 and JHH7 cells, respectively[1].
BLU9931 (0.3-300 nM; 1 hour; MDA-MB-453 and Hep 3B cells) treatment demonstrates potent, dose-dependent reduction of phosphorylation of FGFR4 signaling pathway components, including fibroblast growth factor receptor substrate 2 (FRS2), MAPK, and AKT in MDA-MB-453 cells. BLU9931 shows dose-dependent inhibition of the signaling cascade downstream of FGFR4. BLU9931 exhibits potent inhibition of phosphorylation of the FGFR4 pathway components in Hep 3B cells. BLU9931 treatment leads to induction of caspase-3/7 activity, indicative of induction of apoptosis that results in inhibition of signaling downstream of FGFR4[1].
BLU9931 (100 nM; 0 -24 hours; Hep 3B cells) treatment increases CYP7A1 mRNA expression and the expression of the proliferative marker EGR1 is inhibited[1].
Western Blot Analysis[1] | Cell Line: | MDA-MB-453 and Hep 3B cells | | Concentration: | 0.3 nM, 1 nM, 3 nM, 10 nM, 30 nM, 100 nM, 300 nM | | Incubation Time: | 1 hour | | Result: | Demonstrated potent, dose-dependent reduction of phosphorylation of FGFR4 signaling pathway components, including fibroblast growth factor receptor substrate 2 (FRS2), MAPK, and AKT in MDA-MB-453 and Hep 3B cells. |
RT-PCR[1] | Cell Line: | Hep 3B cells | | Concentration: | 100 nM | | Incubation Time: | 0 hour, 4 hours, 8 hour, 24 hours | | Result: | Increased CYP7A1 mRNA expression. And the expression of the proliferative marker EGR1 was inhibited. |
