“Pharmacology of rosemary (Rosmarinus officinalis Linn.) and its therapeutic potentials. The use of plants is as old as the mankind. Natural products are cheap and claimed to be safe… It is concluded that rosemary and its constituents especially caffeic acid derivatives such as rosmarinic acid have a therapeutic potential in treatment or prevention of bronchial asthma, spasmogenic disorders, peptic ulcer, inflammatory diseases, hepatotoxicity, atherosclerosis, ischaemic heart disease, cataract, cancer and poor sperm motility.”  http://www.ncbi.nlm.nih.gov/pubmed/10641130

Polyphenols from the Mediterranean herb rosemary (Rosmarinus officinalis) for prostate cancer. This review focuses on the Mediterranean herb, rosemary, its polyphenolic diterpenes (carnosic acid and carnosol) and their role in chemoprevention of prostate cancer. Epidemiological studies suggest a reduced risk of cancer in patients consuming rosemary… These findings warrant further research to understand the potential of rosemary as a cancer chemopreventive agent in prostate cancer.” http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3607075/

Effect of rosemary polyphenols on human colon cancer cells: transcriptomic profiling and functional enrichment analysis…rosemary polyphenols…may contribute to colon cancer cell death… Carnosol, one of the main polyphenols in rosemary, poses strong antioxidant and chemopreventive activities. This diterpene has demonstrated anti-inflammatory and anticancer activities on prostate, skin, breast, leukemia, and colon cancer. Another rosemary diterpene, carnosic acid, has proven antiproliferative activity in colon cancer cells…”  http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3534995/

Δ9-tetrahydrocannabinol and its major metabolite Δ9-tetrahydrocannabinol-11-oic acid as 15-lipoxygenase inhibitors.

“Δ(9)-Tetrahydrocannabinol (Δ(9)-THC), a major component of marijuana, has suggested to suppress atherosclerosis…. Δ(9)-THC seems to be attractive for the prevention of atherosclerosis…

In the present study, Δ(9)-THC was found to be a direct inhibitor for 15-LOX…

Furthermore, Δ(9)-THC-11-oic acid, a major and nonpsychoactive metabolite of Δ(9) -THC, but not another Δ(9)-THC metabolite 11-OH-Δ(9)-THC (psychoactive), was revealed to inhibit 15-LOX.

Taken together, it is suggested that Δ(9) -THC can abrogate atherosclerosis via direct inhibition of 15-LOX, and that Δ(9)-THC-11-oic acid is shown to be an “active metabolite” of Δ(9) -THC in this case.”

Endocannabinoid system in cancer cachexia.

Image result for current opinion in clinical nutrition & metabolic care

“More than 60% of advanced cancer patients suffer from anorexia and cachexia.

This review focuses on the possible mechanisms by which the endocannabinoid system antagonizes cachexia-anorexia processes in cancer patients and how it can be tapped for therapeutic applications.

Cannabinoids stimulate appetite and food intake…

Cannabinoid type 1 receptor activation stimulates appetite and promotes lipogenesis and energy storage.

Further study of cancer-cachexia pathophysiology and the role of endocannabinoids will help us to develop cannabinoids without psychotropic properties, which will help cancer patients suffering from cachexia and improve outcomes of clinical antitumor therapy.”

The endocannabinoid signaling system in cancer.

Image result for trends in pharmacological sciences

“The endocannabinoid system, comprising lipid-derived endocannabinoids, their G-protein-coupled receptors (GPCRs), and the enzymes for their metabolism, is emerging as a promising therapeutic target in cancer.

This report highlights the main signaling pathways for the antitumor effects of the endocannabinoid system in cancer and its basic role in cancerpathogenesis, and discusses the alternative view of cannabinoid receptors as tumor promoters.

We focus on new players in the antitumor action of the endocannabinoid system and on emerging crosstalk among cannabinoid receptors and other membrane or nuclear receptors involved in cancer.”

Cannabinoid CB1 Receptor Is Downregulated in Clear Cell Renal Cell Carcinoma

“Several studies in cell cultures and in animal models have demonstrated that cannabinoids have important antitumoral properties… many of these effects are mediated through cannabinoid (CB) receptors CB1 and CB2…

The obtained data suggest a possible implication of the endocannabinoid system in renal carcinogenesis.”

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2989249/

 

 

Cannabinoid CB1 receptor is expressed in chromophobe renal cell carcinoma and renal oncocytoma.

“Objective: To analyze the mRNA and protein expression of cannabinoid receptors CB1 and CB2 in chromophobe renal cell carcinoma (ChRCC) and renal oncocytoma (RO)…

RESULTS:

Quantitative RT-PCR analysis showed that CB1 mRNA was underexpressed by 12-fold in ChRCC and had a variable expression in RO. CB1 protein showed intense positive immunostaining in both neoplasms. Both CB2 mRNA and protein were not expressed in tumor and non tumorrenal tissue.

CONCLUSION:

This distinct immunoprofile may eventually be used as an additional tool with practical interest in the differential diagnosis of renal tumors.”

HIV/AIDS Cure May Be Found In Marijuana: Study

“It is even more evidence of our need for the government to stop punishing patients for using this relatively safe and non-toxic treatment method … ”

“For years, many Americans with HIV/AIDS have used medical marijuana to relieve some common symptoms associated with the illness such as nausea, vomiting and appetite loss.

Now, a new study published last week in the journal AIDS Researcher and Human Retroviruses found that a daily dosage of marijuana’s psychoactive ingredient tetrahydrocannabinol, or THC, may actually fight the HIV/AIDS virus itself.”

HIV Infections Cured With Cannabis a Real Possibility

“Researchers are looking into the use of THC (tetrahydrocannabinol), the active ingredient in marijuana, to help stop the spread of HIV infection.

Hundreds of marijuana researchers have reported that THC was able to pierce the RIV virus in monkeys. That particular virus is almost identical to the HIV virus found in humans, so this news is very encouraging.

The greatest drawbacks to this excellent news are the current laws preventing testing on human candidates.

With the changing of these restrictive laws, HIV infections have a great chance of being cured, with cannabis as a real possible player in the race to stop the disease.”
