“It has been shown that leukemia and glioma cells are sensitive to cannabidiol (CBD)-induced apoptosis (programmed cell death)….the cellular events and sensitivity to CBD-induced apoptosis between murine thymocytes and EL-4 thymoma cells were compared. Cannabidiol markedly induced apoptosis in a time- and concentration-related manner in both cells… The results demonstrated that both thymocytes and EL-4 thymoma cells were susceptible to CBD-induced apoptosis…”

Involvement of the endocannabinoid system in periodontal healing
Endocannabinoids including anandamide (AEA) and 2-arachidonoylglycerol (2-AG) are important lipid mediators for immunosuppressive effects and for appropriate homeostasis via their G-protein-coupled cannabinoid (CB) receptors in mammalian organs and tissues, and may be involved in wound healing in some organs. The physiological roles of endocannabinoids in periodontal healing remain unknown. We observed upregulation of the expression of CB1/CB2 receptors localized on fibroblasts and macrophage-like cells in granulation tissue during wound healing in a wound-healing model in rats, as well as an increase in AEA levels in gingival crevicular fluid after periodontal surgery in human patients with periodontitis. In-vitro, the proliferation of human gingival fibroblasts (HGFs) by AEA was significantly attenuated by AM251 and AM630, which are selective antagonists of CB1 and CB2, respectively. CP55940 (CB1/CB2 agonist) induced phosphorylation of the extracellular-regulated kinases (ERK) 1/2, p38 mitogen-activated protein kinase (p38MAPK), and Akt in HGFs. Wound closure by CP55940 in an in-vitro scratch assay was significantly suppressed by inhibitors of MAP kinase kinase (MEK), p38MAPK, and phosphoinositol 3-kinase (PI3-K). These findings suggest that endocannabinoid system may have an important role in periodontal healing.

Cannabinoids: A new hope for breast cancer therapy?
“Experimental evidence accumulated during the last decade supports that cannabinoids, the active components of Cannabis sativa and their derivatives, possess anticancer activity… these compounds exert anti-proliferative, pro-apoptotic, anti-migratory and anti-invasive actions in a wide spectrum of cancer cells… Moreover, tumor growth, angiogenesis and metastasis are hampered by cannabinoids… our current knowledge on the anti-tumor potential of cannabinoids in breast cancer… suggests that cannabinoid-based medicines may be useful for the treatment of most breast tumor subtypes.”
Cannabinoid receptor type 1 and 2 expression in the skin of healthy dogs and dogs with atopic dermatitis
“Cannabinoid receptor type 1 and 2 expression in the skin of healthy dogs and dogs with atopic dermatitis…The endocannabinoid system and cannabimimetic compounds protect against effects of allergic inflammatory disorders in various species of mammals. Results of the present study contributed to knowledge of the endocannabinoid system and indicated this system may be a target for treatment of immune-mediated and inflammatory disorders such as allergic skin diseases in dogs.”
The effects of hempseed meal intake and linoleic acid on Drosophila models of neurodegenerative diseases and hypercholesterolemia
“Hemp seed is rich in polyunsaturated fatty acids (PUFAs), which have potential as therapeutic compounds for the treatment of neurodegenerative and cardiovascular disease.
In this study, we assessed the effects of the intake of hempseed meal (HSM) and PUFAs on oxidative stress, cytotoxicity and neurological phenotypes, and cholesterol uptake, using Drosophila models.
HSM intake was shown to reduce H(2)O(2) toxicity markedly, indicating that HSM exerts a profound antioxidant effect.
Meanwhile, intake of HSM, as well as linoleic or linolenic acids (major PUFA components of HSM) was shown to ameliorate Aβ42-induced eye degeneration, thus suggesting that these compounds exert a protective effect against Aβ42 cytotoxicity.
Additionally, intake of HSM or linoleic acid was shown to reduce cholesterol uptake significantly.
Moreover, linoleic acid intake has been shown to delay pupariation, and cholesterol feeding rescued the linoleic acid-induced larval growth delay, thereby indicating that linoleic acid acts antagonistically with cholesterol during larval growth.
In conclusion, our results indicate that HSM and linoleic acid exert inhibitory effects on both Aβ42 cytotoxicity and cholesterol uptake, and are potential candidates for the treatment of Alzheimer’s disease and cardiovascular disease.”

“A number of previous studies have shown that polyunsaturated fatty acids (PUFAs) and phytosterols are critically important for human health. Hempseed is a rich source of plant oil, which contains more than 80% PUFAs and 3922-6719 mg/kg of phytosterols (e.g., sitosterol and campesterol). The fatty acids in hempseed oil include a variety of essential fatty acids, including linoleic acid ”

Cannabidiol protects oligodendrocyte progenitor cells from inflammation-induced apoptosis by attenuating endoplasmic reticulum stress
“Cannabidiol (CBD) is the most abundant cannabinoid in Cannabis sativa that has no psychoactive properties. CBD has been approved to treat inflammation, pain and spasticity associated with multiple sclerosis (MS), of which demyelination and oligodendrocyte loss are hallmarks. Thus, we investigated the protective effects of CBD against the damage to oligodendrocyte progenitor cells (OPCs) mediated by the immune system… Cannabidiol protects oligodendrocyte progenitor cells… These findings suggest that attenuation of the ER stress pathway is involved in the ‘oligoprotective’ effects of CBD during inflammation.”
