YAP1 and urinary bladder cancer: Additionally, a study screening a small-molecule compound library to identify novel drugs targeting the Hippo pathway found that DMPCA (N-(3,4-dimethoxyphenethyl)-6-methyl-2,3,4,9-tetrahydro-1H-carbazol-1-amine) can induce phosphorylation of LATS1 and YAP1/TAZ in bladder cancer cells.
