ODP555 In-vitro Combo Treatments of Human Melanoma (1205Lu, WM238) Cell Lines with Curcumin, Vitamins and Steroids

Abstract

Abstract Previous combo treatment experiments on BLM human melanoma cell line identified two combos vit-A + RU-486 and Cur+P+RU as the best combinations to decrease melanoma cell growth as well as IL-8 secretion in -vitro. In order to confirm this finding, experiments were repeated on two other human melanoma cell lines 1205Lu and WM238. Initial single or solo compound treatment on 1205Lu cells resulted in cell growth in the range of 37–59% compared to untreated control 1205Lu cell growth at 100%. A double combo treatment with combinations such as D+P, D+RU, A+P, A+RU, A+D resulted in cell growth in the range of 17 to 37% on the 1205Lu cell line. Whereas on WM238 cell line resulted in cell growth in between 18–22%. A triple combo such as combinations of three compounds (Cur+P+RU, Cur+A+P, Cur+D+RU) resulted in cell growth in the range of 19-30% on 1205Lu cells, whereas on WM238 cells resulted in between 19–20% cell growth. Elisarray of the supernatants from the combos which showed a significant decrease in cell growth revealed the regulation only in IL-8 secretion. IL-8 secretion in the supernatants of combos treated with A+RU and Cur+P+RU was17.5 and 8. 0 pg/ml respectively on the 1205Lu cell line. Whereas, IL-8 secretion was 0.515 and 0.926 pg/ml respectively in the supernatants of A+RU and Cur+P+RU combo treatments on the WM238 cell line. Conclusion Based on cell growth, Elisarray and IL-8 quantitation, two combos A+RU and Cur+P+RU also fared well on the two other cell lines 1205Lu and WM238. Presentation: No date and time listed
