[Enhanced effect of reserpine on growth-inhibitory action of ACNU on ACNU resistance C6 glioma].
Reserpine was found to enhance the effect of ACNU on ACNU-resistant C6 glioma (C6/ACNU). When reserpine was added to the culture medium at the concentration of 10 microM, the IC50 of ACNU for C6/ACNU was decreased to the level of that for C6. Intracellular uptake of ACNU increased in both resistant and sensitive cells when 10 microM reserpine was added to the culture medium. This phenomenon is more remarkable in C6/ACNU than in C6.
