“(OTC: MJNA), a leading hemp industry innovator, is pleased to report on a September 18 San Francisco Chronicle Article, “Pot compound seen as tool against cancer.” The article states that scientists at California Pacific Medical Center who have been researching marijuana’s compounds for the 20 years have found that Cannabidiol, or CBD, has the ability to “turn off” the DNA that causes “breast and other types of cancers” to metastasize. CBD is the second-most abundant cannabinoid within marijuana, but does not cause the psychotropic high of THC.

As stated in the article: “We started by researching breast cancer,” said scientist Pierre Desprez. “But now we’ve found that Cannabidiol works with many kinds of aggressive cancers–brain, prostate–any kind in which these high levels of ID-1 are present.” Desprez said he is hopeful clinical trials will begin immediately. He currently has grant funding through the National Institutes of Health, Susan G. Komen for the Cure, the U.S. Department of Defense and the California Breast Cancer Research Program.

As previously announced in the MJNA press release dated September 5, MJNA portfolio company, Red Dice Holdings, recently launched its Hemp-based high concentrate CBD health and wellness products, Dixie X, for over-the-counter sales. These Cannabidiol products represent the highest strength of CBD products on the market today, and this same concentrate will soon be used to launch the CanChew Biotechnologies line of CBD-enriched chewing gum. Click here for recent production news from PhytoSphere. Dixie X can currently be purchased in over 100 retail locations in Colorado, Arizona and New Mexico as well as on-line by anyone living in the U.S.

In short, MJNA and its portfolio company, PhytoSphere Systems, currently produces non-THC, high quality CBD enriched Hemp oil that according to this story, may fight the most aggressive forms of cancers we know of today.

Studies, such as those in this article and at Project CBD, have continually shown that these non-psychoactive CBD wellness products provide powerful relief for pain and anxiety sufferers, but without the euphoric effects provided by THC. The CBD health and wellness industry is estimated by MJNA to be a $5 billion market.”

“Cannabis Science (CBIS), a pioneering U.S. Biotech Company developing pharmaceutical products for global public health challenges, reports on a recent press release by the San Francisco NBC news, with new studies by Scientists at California Pacific Medical Center, which have shown that cannabidiol, (CBD -1.18%, news), has the ability to “turn off” a gene that causes breast and other types of cancers to metastasize, according to the San Francisco Chronicle newspaper.

NBC News reports, “The drug “has been shown to reduce pain and nausea” in cancer patients. AIDS patients also use cannabis to eat, sleep and otherwise be more functional. Turns out that cannabidiol has none of the psychotropic effects of marijuana as a whole. The researchers hope to move to clinical trials on humans soon to test the cannabidiol inhibition of metastasis, reported in the San Francisco Chronicle. “What they found is that the cannabinoid turns off the overexpression of ID-1, which makes the cells lose their ability to travel to distant tissues. In other words, it keeps the cells more local and blocks their ability to metastasize. (spread to a new location) The researchers stressed cannabidiol works only on cancer cells that have these high levels of ID-1 and these do not include all cancerous tumors but, rather, aggressive, metastatic cells. But they’ve found such high levels in leukemia, colorectal, pancreatic, lung, ovarian, brain and other cancers.””

(NBC Bay Area) “The “medical” bit of medical marijuana may be legitimate after all: Turns out a component of cannabis fights cancer, according to research.

Scientists at California Pacific Medical Center found that cannabidiol, or CBD, has the ability to “turn off” the DNA that causes “breast and other types of cancers” to metastasize, according to the San Francisco Chronicle.

“If this plant were discovered in the Amazon today, scientists would be falling all over each other to be the first to bring it to market,” said Dr. Donald Abrams, chief of oncology at the University of California San Francisco, which has also found science behind marijuana’s efficacy.

The drug “has been shown to reduce pain and nausea” in cancer patients, the newspaper reported. AIDS patients also swear by cannabis for its ability to allow them to eat, sleep and otherwise function.

Turns out that cannabidiol has none of the psychotropic effects of marijuana as a whole, according to the newspaper.”

“The administration of the non-psychotropic cannabis plant constituent cannabidiol (CBD) is protective in an experimental model of colon cancer, according to preclinical trial data published online in the Journal of Molecular Medicine.

Investigators at the University of Naples assessed the effect of CBD on colon carcinogenesis in mice. Researchers reported that CBD administration was associated with cancerous tumor reduction and reduced cell proliferation.

Authors wrote: “Although cannabidiol has been shown to kill glioma cells, to inhibit cancer cell invasion and to reduce the growth of breast carcinoma and lung metastases in rodents, its effect on colon carcinogenesis has not been evaluated to date. This is an important omission, since colon cancer affects millions of individuals in Western countries. In the present study, we have shown that cannabidiol exerts (1) protective effects in an experimental model of colon cancer and (2) antiproliferative actions in colorectal carcinoma cells.”

Authors also acknowledged that CBD possesses “an extremely safe profile in humans.” They concluded, “[O]ur findings suggest that cannabidiol might be worthy of clinical consideration in colon cancer prevention.””

“The endocannabinoid system comprises the G-protein coupled CB1 cannabinoid receptor (CB1R) and CB2 cannabinoid receptor (CB2R), their endogenous ligands (endocannabinoids), and the enzymes responsible for their synthesis and catabolism. Recent works have revealed several important interactions between the endocannabinoid system and cancer. Moreover, it is now well established that synthetic small molecule cannabinoid receptor agonist acting on either CB1R or CB2R or both exert anti-cancer effects on a variety of tumor cells. Recent results from many laboratories reported that the expression of CB1R and CB2R in prostate cancer, breast cancer, and many other cancer cells are higher than corresponding non-malignant tissues. The mechanisms by which cannabinoids acting on CB1R or CB2R exert their effects on cancer cells are quite diverse and complex. Further, several studies demonstrated that some of the anti-proliferative and apoptotic effects of cannabinoids are mediated by receptor-independent mechanisms. In this minreview we provide an overview of the major findings on the effects of endogenous and/or synthetic cannabinoids on breast and prostate cancer. We also provide insight into receptor independent mechanisms of the anti-cancer effects of cannabinoids under in vitro and in vivo conditions.” http://www.ncbi.nlm.nih.gov/pubmed/23069587

According to the Chronicle article, when scientists first exposed metastatic cancer cells to Cannabidiol in a petri dish, “the cells not only stopped acting crazy but they also started to revert to a normal state. Both scientists were shocked…But they got the same results each time they did it.”

“This article and the findings it reports just confirm what many have known, that Cannabidiol or CBD have tremendous health and wellness potential. We are pleased that our Dixie X line of products are available right now to patients who have an immediate need for CBD and are searching for an easy way to find it,” states Ted Caligiuri, Interim President of MJNA. “We take great pride in knowing that our Dixie X line may be of significant health benefit to not only all cancer patients, but those in late stages of metastatic disease. We are also looking forward to the clinical trials that will soon be underway and thank the National Institute of Health, Susan G. Komen Foundation and others for their unwavering commitment to funding this necessary research.”

“Marijuana, already shown to reduce pain and nausea in cancer patients, may be promising as a cancer-fighting agent against some of the most aggressive forms of the disease.

A growing body of early research shows a compound found in marijuana – one that does not produce the plant’s psychotropic high – seems to have the ability to “turn off” the activity of a gene responsible for metastasis in breast and other types of cancers.

Two scientists at San Francisco’s California Pacific Medical Center Research Institute first released data five years ago that showed how this compound – called cannabidiol – reduced the aggressiveness of human breast cancer cells in the lab.”

Marijuana’s better known cannabinoid – delta-9 tetrahydrocannabinol, or THC – had already shown some anticancer properties in tumors, but the non-psychotropic cannabidiol had largely gone unstudied. McAllister initial research showed CBD had anticancer potential as well.”

“A compound found in cannabis could halt the spread of many forms of aggressive cancer, scientists have claimed.

Researchers found that the compound, called cannabidiol, had the ability to “switch off” the gene responsible for metastasis in an aggressive form of breast cancer, the Daily Mail reported.

Importantly, this substance does not produce the psychoactive properties of the cannabis plant.

The team from the California Pacific Medical Center, in San Francisco, first spotted its potential five years ago, after it stopped the proliferation of human breast cancer cells in the lab, the report said.

They discovered that the compound had turned off the overexpression of ID-1, stopping them from travelling to distant tissues.

Other potentially treatable cancers are forms of leukaemia, lung, ovarian and brain cancers, which also have high levels of ID-1.”

“Cannabinoids are a class of pharmacologic compounds that offer potential applications as antitumor drugs, based on the ability of some members of this class to limit inflammation, cell proliferation, and cell survival. In particular, emerging evidence suggests that agonists of cannabinoid receptors expressed by tumor cells may offer a novel strategy to treat cancer. Here, we review recent work that raises interest in the development and exploration of potent, nontoxic, and nonhabit forming cannabinoids for cancer therapy.

 there is overwhelming evidence to suggest that cannabinoids can be explored as chemotherapeutic agents for the treatment of cancer.”

The endogenous cannabinoid anandamide inhibits human breast cancer cell proliferation

Posted on by

“Anandamide was the first brain metabolite shown to act as a ligand of “central” CB1 cannabinoid receptors. Here we report that the endogenous cannabinoid potently and selectively inhibits the proliferation of human breast cancer cells in vitro. Anandamide dose-dependently inhibited the proliferation of MCF-7 and EFM-19 cells with IC50 values between 0.5 and 1.5 microM and 83-92% maximal inhibition at 5-10 microM. The proliferation of several other nonmammary tumoral cell lines was not affected by 10 microM anandamide. The anti-proliferative effect of anandamide was not due to toxicity or to apoptosis of cells but was accompanied by a reduction of cells in the S phase of the cell cycle. A stable analogue of anandamide (R)-methanandamide, another endogenous cannabinoid, 2-arachidonoylglycerol, and the synthetic cannabinoid HU-210 also inhibited EFM-19 cell proliferation, whereas arachidonic acid was much less effective. These cannabimimetic substances displaced the binding of the selective cannabinoid agonist [3H]CP 55, 940 to EFM-19 membranes with an order of potency identical to that observed for the inhibition of EFM-19 cell proliferation. Moreover, anandamide cytostatic effect was inhibited by the selective CB1 receptor antagonist SR 141716A. Cell proliferation was arrested by a prolactin mAb and enhanced by exogenous human prolactin, whose mitogenic action was reverted by very low (0.1-0.5 microM) doses of anandamide. Anandamide suppressed the levels of the long form of the prolactin receptor in both EFM-19 and MCF-7 cells, as well as a typical prolactin-induced response, i.e., the expression of the breast cancer cell susceptibility gene brca1. These data suggest that anandamide blocks human breast cancer cell proliferation through CB1-like receptor-mediated inhibition of endogenous prolactin action at the level of prolactin receptor.”
