抄録	Cancer-associated fibroblasts (CAFs), a major component of the tumor microenvironment, play an important role in tumor progression. Colon cancer cells deficient in p53 activate fibroblasts and enhance fibroblast-mediated tumor growth. Meflin is a CAF marker capable of inhibiting tumor growth. In this study, we investigated the role of Meflin in fibroblasts using human cell lines (colon cancer HCT116 and fibroblasts CCD-18Co) and clinical specimens. TP53-suppressed HCT116 (HCT116ˢʰ ᵖ⁵³) cells cocultured with CCD-18Co cells showed significantly faster proliferation than HCT116ˢʰ ᶜᵒⁿᵗʳᵒˡ cells. In xenograft experiments, the volume of tumors induced by coinoculation with HCT116ˢʰ ᵖ⁵³ and CCD-18Co cells was significantly larger than that induced by HCT116ˢʰ ᶜᵒⁿᵗʳᵒˡ cells co-inoculated with CCD-18Co cells. HCT116sh p53 cells increased the levels of CAF-like phenotypic markers in CCD-18Co cells. Moreover, Meflin expression was significantly reduced in CCD-18Co cells cocultured with HCT116ˢʰ ᵖ⁵³ cells compared to that in CCD-18Co cells cocultured with HCT116ˢʰ ᶜᵒⁿᵗʳᵒˡ cells. si-RNA-mediated inhibition of Meflin activated CCD-18Co cells into tumor-promoting CAF-like cells, which significantly promoted xenograft tumor growth. Overexpression of Meflin in CCD-18Co cells using lentivirus suppressed fibroblast-mediated growth of HCT116ˢʰ ᵖ⁵³ tumor xenografts. The expression of Meflin in CCD-18Co cells was suppressed by TGF-β and enhanced by vitamin D. These results indicate that colon cancer cells deficient in p53 suppress Meflin expression in fibroblasts, which affects tumor growth by altering the properties of tumor growth-promoting CAFs. Our results suggest that targeting Meflin in fibroblasts may be a novel therapeutic strategy for colorectal cancer.

DCTERMS.abstract	Cancer-associated fibroblasts (CAFs), a major component of the tumor microenvironment, play an important role in tumor progression. Colon cancer cells deficient in p53 activate fibroblasts and enhance fibroblast-mediated tumor growth. Meflin is a CAF marker capable of inhibiting tumor growth. In this study, we investigated the role of Meflin in fibroblasts using human cell lines (colon cancer HCT116 and fibroblasts CCD-18Co) and clinical specimens. TP53-suppressed HCT116 (HCT116ˢʰ ᵖ⁵³) cells cocultured with CCD-18Co cells showed significantly faster proliferation than HCT116ˢʰ ᶜᵒⁿᵗʳᵒˡ cells. In xenograft experiments, the volume of tumors induced by coinoculation with HCT116ˢʰ ᵖ⁵³ and CCD-18Co cells was significantly larger than that induced by HCT116ˢʰ ᶜᵒⁿᵗʳᵒˡ cells co-inoculated with CCD-18Co cells. HCT116sh p53 cells increased the levels of CAF-like phenotypic markers in CCD-18Co cells. Moreover, Meflin expression was significantly reduced in CCD-18Co cells cocultured with HCT116ˢʰ ᵖ⁵³ cells compared to that in CCD-18Co cells cocultured with HCT116ˢʰ ᶜᵒⁿᵗʳᵒˡ cells. si-RNA-mediated inhibition of Meflin activated CCD-18Co cells into tumor-promoting CAF-like cells, which significantly promoted xenograft tumor growth. Overexpression of Meflin in CCD-18Co cells using lentivirus suppressed fibroblast-mediated growth of HCT116ˢʰ ᵖ⁵³ tumor xenografts. The expression of Meflin in CCD-18Co cells was suppressed by TGF-β and enhanced by vitamin D. These results indicate that colon cancer cells deficient in p53 suppress Meflin expression in fibroblasts, which affects tumor growth by altering the properties of tumor growth-promoting CAFs.
