Cancer research awareness and the cannabinoid system (CS) are the focus of May’s health update from Publius and The Cannabis Papers: A citizen’s guide to cannabinoids (2011). This month: PubMed CS science on preventing skin and colon carcinogenesis, phototherapy, melanomas, eicosands, gliomas, mitochondria and the omega-3 fatty acids DHA and EPA.
2014 ~ Skin Carcinogenesis, Inflammation and the CS

2014 ~ CB2 Receptor and Melanoma
“Extravasation of leukocytes through the BBB [blood-brain barrier] is decreased by the activation of type 2 cannabinoid receptors (CB2); therefore, in the present study we sought to investigate the role of CB2 receptors in the interaction of melanoma cells with the brain endothelium. … Our data identify CB2 as a potential target in reducing the number of brain metastastes originating from melanoma.”
CB2 Receptor Activation Inhibits Melanoma Cell Transmigration through the Blood-Brain Barrier.

2014 ~ Eicosands, 2-AG and Cancer
“While THC and its derivatives have garnered notoriety in the eyes of the public, the endocannabinoid system consists of two endogenous signaling lipids, 2-arachidonoylglycerol (2-AG) and N-arachidonoylethanolamine (anandamide), which activate cannabinoid receptors CB1 and CB2 in the nervous system and peripheral tissues.”
Chemical approaches to therapeutically target the metabolism and signaling of the endocannabinoid 2-AG and eicosanoids.

2013 ~ Anticancer Effects of CBD
“Thus, VDAC1 [voltage-dependent anion channel 1] seems to serve as a novel mitochondrial target for CBD. The inhibition of VDAC1 by CBD may be responsible for the immunosuppressive and anticancer effects of CBD.”
Direct modulation of the outer mitochondrial membrane channel, voltage-dependent anion channel 1 (VDAC1) by cannabidiol: a novel mechanism for cannabinoid-induced cell death.

2010 ~ Preventing Carcinogenesis and the CS
“Our findings suggest that the expression of cannabinoid receptors and of FAAH in some tumour cells could well influence the effectiveness of DHA and EPA or their ethanolamide derivatives as anticancer agents.”
Cannabinoid receptor-dependent and -independent anti-proliferative effects of omega-3 ethanolamides in androgen receptor-positive and -negative prostate cancer cell lines.
