Cannabis Smoking and Diabetes Mellitus: Results from Meta-analysis with Eight Independent Replication Samples.

“Epidemiologic data, suggest an inverse cannabis smoking-diabetes mellitus association.

RESULTS:

Recently active cannabis smoking and diabetes mellitus are inversely associated. The meta-analytic summary odds ratio is 0.7 (95% confidence interval = 0.6, 0.8).

CONCLUSIONS:

Current evidence is too weak for causal inference, but there now is a more stable evidence base for new lines of clinical translational research on a possibly protective (or spurious) cannabis smoking-diabetes mellitus association suggested in prior research.”

Endocannabinoid and ceramide levels are altered in patients with colorectal cancer.

“Endocannabinoids and ceramides have demonstrated growth inhibition, cell death induction and pro-apoptotic activity in cancer research.

In the present study, we describe the profiles of two major endocannabinoids, ceramides, free fatty acids and relevant metabolic enzymes in 47 pairs of human colorectal cancer tissues and adjacent non-tumor tissues…

Elevation of AEA and alteration of ceramides (C16, C24, C18, C20) may qualify as potential endogenous biomarkers and novel drug targets for colorectal cancer.”

The successful use of dronabinol for failure to thrive secondary to intestinal dysmotility.

“Symptoms of severe intestinal dysmotility decrease patients’ quality of life and may prevent them from sustaining adequate oral intake. Dronabinol is a synthetic cannabinoid that is labeled for use in AIDS-related anorexia and chemotherapy-associated nausea and vomiting that has additional efficacy in patients with other etiologies of nausea, vomiting, and anorexia.

PRESENTATION OF CASE:

We present a 58-year-old female with a history of nausea, vomiting, abdominal pain, and inability to maintain oral intake after multiple laparotomies for ectopic pregnancy, recurrent caecal volvulus, and cholecystitis. After eight years of unsuccessful trials of medicines, dietary modifications, and a partial colectomy, she began a trial of dronabinol, which caused almost complete remission of her symptoms. When this medication was discontinued by her payer, she was unable to maintain oral intake and therefore, was admitted to the hospital for fluid resuscitation and resumption of dronabinol.

DISCUSSION:

The use of dronabinol in this patient with severe intestinal dysmotility allowed her to maintain her nutritional status orally and obviated the need for enteral or parenteral feeding. Unfortunately, it was not covered by her insurance company for this indication.

CONCLUSION:

Dronabinol has the potential to improve quality of life for patients beyond those undergoing chemotherapy or suffering from AIDS. Lack of access to this medicine for patients with intestinal dysmotility after all other modalities have been tried can lead to morbid and expensive complications, such as inpatient admission and surgery for enteral access.”

“Our experience with this demonstrates that dronabinol can be an effective and well-tolerated treatment option for nausea, vomiting, and abdominal pain secondary to intestinal dysmotility where other modalities have failed.”  http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4446691/

AM251 induces apoptosis and G2/M cell cycle arrest in A375 human melanoma cells.

“Human cutaneous melanoma is an aggressive and chemotherapy-resistant type of cancer. AM251 is a cannabinoid type 1 (CB1) receptor antagonist/inverse agonist with off-target antitumor activity against pancreatic and colon cancer cells. The current study aimed to characterize the in-vitro antimelanoma activity of AM251…

This study provides the first evidence of a proapoptotic effect and G2/M cell cycle arrest of AM251 on A375 cells. This compound may be a potential prototype for the development of promising diarylpyrazole derivatives to be evaluated in human cutaneous melanoma.”

The Lysophosphatidylinositol Receptor GPR55 Modulates Pain Perception in the Periaqueduactal Grey.

“Emerging evidence indicates the involvement of GPR55 and its proposed endogenous ligand, lysophosphatidylinositol (LPI), in nociception…

Thus, we provide the first pharmacological evidence that GPR55 activation at central levels is pronociceptive, suggesting that interfering with GPR55 signaling in the PAG may promote analgesia.”

Activation of GPR55 Receptors Exacerbates oxLDL-Induced Lipid Accumulation and Inflammatory Responses, while Reducing Cholesterol Efflux from Human Macrophages.

“The G protein-coupled receptor GPR55 has been proposed as a new cannabinoid receptor associated with bone remodelling, nervous system excitability, vascular homeostasis as well as in several pathophysiological conditions including obesity and cancer.

Our data suggest that GPR55 could play deleterious role in ox-LDL-induced foam cells and could be a novel pharmacological target to manage atherosclerosis and other related cardiovascular diseases.”

Astroglial type-1 cannabinoid receptors (CB1): A new player in the tripartite synapse.

“The endocannabinoid system is an important regulator of physiological functions. In the brain, this control is mainly exerted through the type-1-cannabinoid (CB1) receptors. CB1 receptors are abundant at neuron terminals where their stimulation inhibits neurotransmitter release. However, CB1receptors are also expressed in astrocytes and recent studies showed that astroglial cannabinoid signalling is a key element of the tripartite synapse. In this review we discuss the different mechanisms by which astroglial CB1 receptors control synaptic transmission and plasticity. The recent involvement of astroglial CB1 receptors in the effects of cannabinoids on memory highlights their key roles in cognitive processes and further indicates that astrocytes are central active elements of high order brain functions.”

Dopaminergic function in cannabis users and its relationship to cannabis-induced psychotic symptoms.

“Substance dependence and schizophrenia are both associated with dopaminergic dysfunction.

It has been proposed, although never directly tested, that the link between cannabis use and schizophrenia is mediated by altered dopaminergic function.

These findings indicate that chronic cannabis use is associated with reduced dopamine synthesis capacity and question the hypothesis that cannabis increases the risk of psychotic disorders by inducing the same dopaminergic alterations seen in schizophrenia.”

http://www.ncbi.nlm.nih.gov/pubmed/23820822

“There is robust evidence that stimulants increase striatal dopamine levels and some evidence that alcohol may have such an effect, but little evidence, if any, that cannabis and opiates increase dopamine levels. Moreover, there is good evidence that striatal dopamine receptor availability and dopamine release are diminished in individuals with stimulant or alcohol dependence but not in individuals with opiate, nicotine or cannabis dependence.”  http://www.ncbi.nlm.nih.gov/pubmed/25873042

Hemp (Cannabis sativa L.).

“Hemp (Cannabis sativa L.) suspension culture cells were transformed with Agrobacterium tumefaciens strain EHA101 carrying the binary plasmid pNOV3635. The plasmid contains a phosphomannose isomerase (PMI) selectable marker gene. Cells transformed with PMI are capable of metabolizing the selective agent mannose, whereas cells not expressing the gene are incapable of using the carbon source and will stop growing. Callus masses proliferating on selection medium were screened for PMI expression using a chlorophenol red assay. Genomic DNA was extracted from putatively transformed callus lines, and the presence of the PMI gene was confirmed using PCR and Southern hybridization. Using this method, an average transformation frequency of 31.23% ± 0.14 was obtained for all transformation experiments, with a range of 15.1-55.3%.”

The effects of Cannabis sativa L. seed (hempseed) in the ovariectomized rat model of menopause.

“Cannabis sativa L. has been used for the treatment of various gynecological diseases in traditional medicine.

The potential of this plant to protect against complications of menopause has been raised but rarely studied.

The effects of hempseed on plasma lipid and lipoprotein profiles, estradiol and calcium levels were evaluated.

These results suggest that hempseed may improve post-ovariectomy complications in rats.”
