GA-017 (GA017) is a potent, selective, ATP-competitive LATS kinase (LATS1/2) inhibitor with IC50 of 4.10/3.92 nM, respectively, promotes cell growth.
GA-017 increases the number and size of spheroids of various cell-types in both scaffold-based and scaffold-independent cultures.
GA-017 also enhances the ex vivo formation of mouse intestinal organoids.
GA-017 facilitates the growth of spheroids and organoids by stabilizing and translocating YAP/TAZ into the cell nucleus.
GA-017 inhibits the Hippo pathway to promote YAP/TAZ stabilization and nuclear translocation.
GA-017 induces expression of Hippo pathway-related genes such as ANKRD1, CYR61, and CTGF in SKOV3 cells in a time- and dose-dependent manner.
GA-017 inhibited the activity of 16 kinases of the AGC family at 100 nM against a panel of 321 diverse kinases.
The serine/threonine protein kinases LATS (LATS1/2) phosphorylate YAP/TAZ, key effectors of the growth- and proliferation-regulating Hippo signaling pathway.
