The decreased expression of ROR1 significantly reduced the levels of IFN-γ and anti-ROR1 antibody but enhanced the TGF-β level in shROR1-HO8910 CSC-vaccinated mice compared to those in the HO8910 CSC-vaccinated mice (Figures 5(h)–5(j)) and in the ID8 cancer stem-like cell-vaccinated mice (Figures 5(k)–5(m)). This evidence concerns the gene TGFB1 and cancer.
