Regarding correlations of TβRIII with expression of other TGF-β related molecules in this glioblastoma patient cohort, only a correlation in newly diagnosed glioblastoma (tumor cells) of protein levels of TβRIII and TGF-β1 (r = 0.339, p = 0.046) and in recurrent glioblastoma (tumor cells) of protein levels of TβRIII and pSmad1/5/8 (r = 0.898, p = 0.033) were detected (Supplementary Table 2). The gene discussed is TGFB1; the disease is glioblastoma.
