1 Molecular mechanism and cytotoxicity of allicin and all-trans retinoic acid against CD44+ versus CD117+ melanoma cells. Tretinoin CD44 molecule (Indian blood group) Homo sapiens
2 To clarify this mechanism, we determined the sensitivity to ATRA, allicin and allicin/ATRA in CD44+ and CD117+ melanoma cell subpopulations. Tretinoin CD44 molecule (Indian blood group) Homo sapiens
3 RESULTS: Here, we demonstrated that CD44+ melanoma cells were more resistant to allicin and ATRA than CD117+ cells. Tretinoin CD44 molecule (Indian blood group) Homo sapiens
4 The combination treatment with allicin and ATRA significantly reduced the IC50 value obtained for ATRA alone in CD44+ melanoma cells. Tretinoin CD44 molecule (Indian blood group) Homo sapiens
5 The combination treatment with allicin and ATRA significantly reduced the IC50 value obtained for ATRA alone in CD44+ melanoma cells. Tretinoin CD44 molecule (Indian blood group) Homo sapiens
6 In CD44+ cells, the IC50 value of ATRA was 37.43 +- 0.54, while the IC50 value of allicin/ATRA treatment was 17.53 +- 0.2 microM. Tretinoin CD44 molecule (Indian blood group) Homo sapiens
7 The combination treatment caused the inhibition of CD44+ and CD117+ melanoma cells at the S phases compared to ATRA alone. Tretinoin CD44 molecule (Indian blood group) Homo sapiens
8 Allicin, ATRA, and allicin/ATRA increased the expression of cyclin D1 mRNA in both CD44+ and CD117+ cells. Tretinoin CD44 molecule (Indian blood group) Homo sapiens
9 Allicin, ATRA, and allicin/ATRA increased the expression of cyclin D1 mRNA in both CD44+ and CD117+ cells. Tretinoin CD44 molecule (Indian blood group) Homo sapiens
10 In contrast, ATRA and the combination treatment significantly increased MMP-9 gene expression in CD44+ cells. Tretinoin CD44 molecule (Indian blood group) Homo sapiens
11 CONCLUSION: Overall, our results indicate that allicin reinforces the ATRA-mediated inhibitory effects on CD44+ and CD117+ melanoma cells and may provide a new approach for the treatment of malignant melanoma. Tretinoin CD44 molecule (Indian blood group) Homo sapiens
