Increased cell proliferation in hCIMP ACC tumors is a likely second driver of augmented DNMT1 and DNMT3A expression, along with copy number aberrations in the DNMT genes. a and b Correlation between DNMT1 (a) or DNMT3A (b) expression and cell proliferation; hCIMP samples (n = 21, orange), iCIMP (n = 26, yellow), and lCIMP (n = 32, blue). c Modeling of inter-dependencies between genomic copy number status of DNMT genes, cell proliferation and gene expression using partial correlations for the TCGA data set. Rpartial stands for the Pearson partial correlation coefficient calculated when controlling for the third factor. d and e Effect of a 48 h treatment with the proliferation inhibitor AZD-5438 (Azd) at 1 or 5 µM on the expression of DNMT1, DNMT3A, DNMT3B, and the proliferation marker MKI67 in the hCIMP and lCIMP ACC cell lines H295R (d) and MUC-1 (e). DMSO was used as the vehicle. Data represent the means from at least four independent experiments ± SEM (Wilcoxon test, *p < 0.05, **p < 0.01)
