TGFB1 and neoplasm: To verify our findings, we further studied the expression of TASL mRNA in different immune subtypes, which was a method of tumor typing proposed by Thorsson V et al. [32] in 2018, including C1 (wound healing); C2 (IFN-γ dominant); C3 (inflammatory); C4 (lymphocyte depleted); C5 (immunologically quiet) and C6 (TGF-β dominant).
