Remarkably, cannabidiol reduced keratin 10 mRNA through a type‐1 cannabinoid (CB<sub>1</sub>) receptor‐dependent mechanism, whereas cannabigerol did not affect either CB<sub>1</sub> or CB<sub>2</sub> receptors of HaCaT cells. In addition, cannabidiol, but not cannabigerol, increased global DNA methylation levels by selectively enhancing DNMT1 expression, without affecting DNMT 3a, 3b or 3L.</p> </sec> <sec id="bph12309-sec-0004" sec-type="section"> <title>Conclusions and Implications</title> <p>These findings show that the phytocannabinoids cannabidiol and cannabigerol are transcriptional repressors that can control cell proliferation and differentiation. This indicates that they (especially cannabidiol) have the potential to be lead compounds for the development of novel therapeutics for skin diseases.</p> </sec> </abstract> … (more)
