The role of androgen receptor in transcriptional modulation of cannabinoid receptor type 1 gene in rat trigeminal ganglia.

Posted on by

“We have previously shown that anti-hyperalgesic effects of cannabinoid agonists under inflammatory condition are much greater in male than female, and that inflammatory cytokines upregulate cannabinoid receptor type 1 (CB1) expression in male, but not female, trigeminal ganglia (TG) in a testosterone-dependent manner. In this study, we investigated the mechanisms underlying the testosterone-mediated regulation of peripheral CB1 expression…

These experiments provided compelling evidence that testosterone regulates CB1 gene transcription in TG through AR following cytokine stimulation.

These results should provide mechanistic bases for understanding cytokine-hormone-neuron interactions in peripheral cannabinoid systems, and have important clinical implications for pain patients in whom testosterone level is naturally low, gradually declining or pharmacologically compromised.”

Bladder function in a cannabinoid receptor type 1 knock-out mouse.

Posted on by

“OBJECTIVE: To evaluate bladder function in an established cannabinoid type 1 (CB1) receptor knock-out mouse model via organ bath (in vitro) and urodynamic (cystometric; in vivo) experiments.

CONCLUSIONS: In vitro, bladder strips from CB1 KO mice responded to muscarinic receptor stimulation similar to WT controls, but were less responsive to electrical stimulation of nerves. In vivo, CB1 KO mice had a higher micturition frequency and more spontaneous activity than WT animals.

The present findings suggest that CB1 receptors are involved in peripheral and central nervous control of micturition.”

Towards a better Cannabis drug.

Posted on by

“Opium smoking has been mostly replaced by i.v. injection of morphine and heroin and we see cocaine sniffing rather than chewing of coca leaves. Cannabis use – be it of marijuana, hashish or bhang – differs.

Any cannabis cognoscente will insist that the crude material is ‘much better’ than pure Δ9 – tetrahydrocannabinol (THC), the only major psychoactive constituent of cannabis (Mechoulam et al., 1970).

Indeed, although pure THC is available as a drug (named Dronabinol) it is apparently not used illicitly.

The pharmacological/biochemical basis for this difference is not clear and is presumably due to several factors. A major reason seems to be the pharmacokinetic difference between cannabis smoking and the oral administration of THC.

 On smoking, the cannabis effects are noted almost immediately, while a 1.5 – 2 hour delay is observed on oral administration.

A further factor may be conditioning to the smell, although there are no published data along these lines. A further factor may be the presence of the terpenoid CB2 agonist beta-caryophyllene in cannabis (Gertsch et al., 2008).

CB2 agonists are well known to cause numerous effects (mostly of a protective nature) which may counteract some of the effects of THC (Pacher & Mechoulam, 2011).”

Protective effect of cannabidiol against cadmium hepatotoxicity in rats.

Posted on by

“The protective effect of cannabidiol, the non-psychoactive component of Cannabis sativa, against liver toxicity induced by a single dose of cadmium chloride was investigated in rats…

 It was concluded that cannabidiol may represent a potential option to protect the liver tissue from the detrimental effects of cadmium toxicity.”

Cannabis Can Prevent Cancer Caused By Cigarette Use, According To New Study

Posted on by

tobacco cigarettes marijuana cannabis

“A new study published by the journal J-Stage, and funded by the Ministry of Education, Culture, Sports, Science and Technology of Japan, has found that cannabinoids – whether THC, CBD or CBDV – were effective at blocking a certain enzyme which is known to cause cancer, and is produced in large amount when cigarettes are consumed.”

“These results suggest that the pentylresorcinol structure in CBD may have structurally important roles in direct CYP1A1 inhibition, although the whole structure of CBD is required for overall inhibition”, according to researchers.

CYP1A1 is an enzyme which isn’t dangerous at low-levels, but is produced in large quantities when someone smokes cigarettes; at large doses, the enzyme has been linked to cancer.

Researchers state that; “Accordingly, CBD and its related compounds, which are potent inhibitors of CYP1A1 activity, would be useful as a lead compound in anticancer chemotherapy.””

Neuroprotection and reduction of glial reaction by cannabidiol treatment after sciatic nerve transection in neonatal rats.

Posted on by

“The clinical use of neurotrophic factors is difficult due to side effects and elevated costs, but other molecules might be effective and more easily obtained. Among them, some are derived from Cannabis sativa.

Cannabidiol (CBD) is the major non-psychotropic component found on the surface of such plant leaves.

The present study aimed to investigate the neuroprotective potential of CBD…

The present results show that CBD possesses neuroprotective characteristics that may, in turn, be promising for future clinical use.”

The CB1 receptor mediates the peripheral effects of ghrelin on AMPK activity but not on growth hormone release.

Posted on by

“This study aimed to investigate whether the growth hormone release and metabolic effects of ghrelin on AMPK activity of peripheral tissues are mediated by cannabinoid receptor type 1 (CB1) and the central nervous system…  Our data suggest that the metabolic effects of ghrelin on AMPK in peripheral tissues are abolished by the lack of functional CB1 receptor via direct peripheral effect and partially through the central nervous system, thus supporting the existence of a possible ghrelin-cannabinoid-CB1-AMPK pathway.”
