Consistently, multigene expression RNAseq signatures correlated well with IHC in patient tumor tissues (scored as previously described [10]), with an enrichment of POSTN‐RNAsign, MYH11‐RNAsign, and PDPN‐RNAsign in IHC‐assigned POSTN‐high (p = 9.8e‐10), MYH11‐high (p = 2.4e‐08), and PDPN‐high tumors (p = 2.1e‐08), respectively (Figure 1D–F). Here, MYH11 is linked to neoplasm.
