Nevertheless the fact that this agent is not psychoactive to any degree and that it can be administered at high doses without apparent toxicity encourages further studies. Cbd Benefits 2015 2017 in conclusion a cannabinoid-based therapeutic strategy for neural diseases devoid of undesired psychotropic side effects could find in CBD a valuable compound in cancer therapies along with the perspective of evaluating a synergistic effect with other cannabinoid molecules and/or with other chemotherapeutic agents as well as with radiotherapy. Whatever the precise mechanism underlying the CBD effects medical cannabidiol oil 2017 cbd how to pronounce vape the buy cbd juice Cbd Benefits 2015 2017 present results suggest a possible application of CBD as a promising nonpsychoactive antineoplastic agent. Acknowledgments We are indebted to GW Pharmaceuticals for kindly providing CBD; we are also grateful to Dr. F.
DNA peak after PI staining of nuclei. In U87 control culture after 24 h of incubation only 2.66 1.38% of the cells underwent a spontaneous apoptosis ( Fig. 4 ). The exposure to the ineffective concentration of CBD in the MTT test at 10 ?M caused an induction of cbd tincture depression cbd apoptosis overlapping that obtained in control cells (7.25 4.03%). By contrast culturing the cells with CBD for 24 h with the IC50 concentration caused an induction of apoptosis in 51.58 4.82% of the total cell population. Similar results were observed in the U373 cells where in the control group the percentage of apoptosis was 2.09 0.16% and the exposure to CBD was found to increase the apoptotic rate from 8.66% 7.77 with 10 ?M to 41.36 11.8 with 25 ?M CBD (data not shown). The addition of CB1 and CB2 cannabinoid antagonists never reversed the CBD-induced cell death (data not shown).
Absence of an effect of PTX on CBD-induced antiproliferation. U87 and U373 cells were preincubated for 18 h with 100 ng/ml PTX and treated with different concentrations of CBD for 24 h. Viability was determined by MTT test. Results correspond to three different experiments and values (.
