PTPRM and cancer: Remarkably, microarray analysis showed that forced YAP1 overexpression in Huh7 cells resulted in increased expression of genes that mediate the acquisition of a stem cells phenotype in cancer of liver and/or other tissues, including MAP2K5 [32, 33], PPM1A [34], PTPN11 [35], PTPRM [36], PDE2A [37] IRF2 [38], LDHA [39] SH3KBP1 [40] and SPSB1 [41].
