We obtained similar results in an independent validation dataset of microarray-based mRNA levels for TGFB1, TGFB2, and TGFB3, and their correlated expression with specific transcription factors in tumor specimens from 41 pediatric patients with DIPG (N = 29) or H3K27M-mutant GBM. This evidence concerns the gene TGFB3 and neoplasm.
