Cocoa presents cytotoxicity against melanoma cancer cell lines (A-375 e B16-F10) and improves chemotherapy activity by increasing oxidative stress. | LitMetric

AI Article Synopsis

  • * The study tested cocoa extracts on melanoma cell lines (A-375 and B16-F10) and found that cocoa significantly decreased cell viability and proliferation while increasing oxidative stress, without harming normal fibroblast cells.
  • * Cocoa also boosted the effectiveness of paclitaxel, a chemotherapy drug, by further reducing melanoma cell growth, suggesting that cocoa could be a promising adjuvant treatment in melanoma therapy.

Article Abstract

Melanoma frequently presents a poor chemotherapy response. In this scenario, investigations for new therapies are essential. Thus, cocoa is highlighted in this area since it presents many biological properties. This study investigated the anticarcinogenic activity of cocoa in melanoma cell lines (A-375 and B16-F10). Melanoma and fibroblast (HFF-1) cell lines were exposed to different concentrations of cocoa seeds (30 to 2000 ug/ml) at 24 and 72 h. Cocoa was also associated with paclitaxel IC50. We conducted viability, proliferation, and oxidative stress analyses. Our findings suggested that cocoa isolated, at almost all concentrations tested, was able to reduce viability and proliferation of B16-F10 cells and proliferation of A-375 cells via oxidative stress increasing. Also, cocoa caused no damage in fibroblast cells. Moreover, cocoa increased paclitaxel activity on A-375 by reducing cell proliferation and increasing oxidative stress. Therefore, the results highlight cocoa as a potent selective adjuvant anticancer agent against melanoma. PRACTICAL APPLICATIONS: In conclusion, more studies should be performed to deeply explore this remarkable action of cocoa as a an promising adjuvant to enhance chemotherapy.
