Standardized extract attenuates tau and stathmin gene expression in the melanoma cell line.

OBJECTIVES

Metastasis is the main cause of death in patients with melanoma. Cannabis-based medicines are effective adjunctive drugs in cancer patients. Tau and Stathmin proteins are the key proteins in cancer metastasis. Here we have investigated the effect of a standardized extract on cell migration and Tau and Stathmin gene expression in the melanoma cell line.

MATERIALS AND METHODS

In the treatment group, melanoma (B1617) was treated 48 hr with various concentrations of standardized extract. Cells with no treatment were considered as the control group, then study was followed by Quantitative RT-Real Time PCR assay. Relative gene expression was calculated by the ΔΔct method. Migration assay was used to evaluate cancer metastasis.

RESULTS

Tau and stathmin gene expression was significantly decreased compared to the control group. Cell migration was also significantly reduced compared to controls.

CONCLUSION

decreased tau and stathmin gene expression and cancer metastasis. The results may have some clinical relevance for the use of cannabis-based medicines in patients with metastatic melanoma.
