Effects of standardized Cannabis sativa extract and ionizing radiation in melanoma cells in vitro

Journal of Cancer Research and Therapeutics “Melanoma causes the highest number of skin cancer-related deaths worldwide. New treatment methods are essential for the management of this life-threatening disease.

Aims: In this study, we investigated the efficacy of a standardized Cannabis sativa extract alone or in combination with single radiation dose (6 Gy) in B16F10 mouse melanoma cells in an extract dose-dependent manner.

Results: Administration of the extract alone or alongside radiation substantially inhibited melanoma cell viability and proliferation in the extract dose response-dependent manner. The inhibition of melanoma cell viability was paralleled by an increase in necrosis but not apoptosis when melanoma cells were treated with the extract alone. Radiation alone did not have any antiproliferative effects, and radiation also did not synergize antiproliferative effects of the extract when the extract and radiation were combined.

Conclusion: Our data suggest that C. sativa extract may have significant health and physiological implications for the treatment of melanoma. The results of this study also indicate that B16F10 mouse melanoma cells are radioresistant. Taken together, these findings may lead to the identification of new therapeutic strategy for the management of melanoma.”

“This study provides the first evidence of antitumor effects of C. sativa extract, when administered alone or in combination with radiation, to mouse melanoma cells in vitro. Our results may verify the value of C. sativa extract for the treatment of melanoma and may complement the therapeutic profile of C. sativa extracts administration in the future.”
