MRTFA and neoplasm: The presence of some of the most highly expressed genes included in panels 1 and 2 according to the microarray experiments—such as matrix metalloproteinase 13 (MMP13), fibroblast growth factor 13 (FGF13), and bone morphogenic protein 7 (BMP7)—in the rafts of tumor cells (MCC14/2, MKL-1, and WAGA) co-cultured with PHKs, was investigated by IHC (Figure 7A).
