CYSLTR2^L129Q-, YAP^AA-, and PLCβ4^D630Y-driven tumors do not display hyperactive ERK staining in the mitfa^−/− context. Genotype abbreviations are as described in Fig. 3. (A and B) Representative images of H&E staining and IHC for YAP, ERK, or phospho-ERK (pERK) on the indicated tumor genotypes. YAP activation is determined by nuclear localization and ERK activation by phospho-ERK. (A) C➛pm+ tumors and Qpm+ tumors are positive for nuclear YAP and phospho-ERK, while C➛pm−, Qpm−, and PLC➛pm− tumors display only YAP activation; n ≥ 3 for all genotypes and stains, except n = 2 for each Y➛pm− and C➛pm+ IHC stains. (B) Q➛Bpm− displays nuclear YAP but not phospho-ERK; n = 5 for all stains. (C) Graph shows the percent of UM tumor cells positive for phospho-ERK quantified by QuPath (n ≥ 3 for all genotypes, except n = 2 for Y➛pm− and C➛pm+), and error bars denote SD. Statistical significance is as follows: C➛pm+ versus C➛pm− P = 0.0435, Q➛pm+ versus Q➛pm− P = 0.0001, Y➛pm+ versus Y➛pm− P = 0.551, as determined by Student’s unpaired t test.
