“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.”

“Medical Marijuana Inc. (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.”

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.”

Pot compound seen as tool against cancer

“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.”

Cannabidiol as a novel inhibitor of Id-1 gene expression in aggressive breast cancer cells

“Invasion and metastasis of aggressive breast cancer cells is the final and fatal step during cancer progression, and is the least understood genetically. Clinically, there are still limited therapeutic interventions for aggressive and metastatic breast cancers available. Clearly, effective and nontoxic therapies are urgently required. Id-1, an inhibitor of basic helix-loop-helix transcription factors, has recently been shown to be a key regulator of the metastatic potential of breast and additional cancers. Using a mouse model, we previously determined that metastatic breast cancer cells became significantly less invasive in vitro and less metastatic in vivo when Id-1 was down-regulated by stable transduction with antisense Id-1. It is not possible at this point, however, to use antisense technology to reduce Id-1 expression in patients with metastatic breast cancer. Here, we report that cannabidiol (CBD), a cannabinoid with a low-toxicity profile, could down-regulate Id-1 expression in aggressive human breast cancer cells. The CBD concentrations effective at inhibiting Id-1 expression correlated with those used to inhibit the proliferative and invasive phenotype of breast cancer cells. CBD was able to inhibit Id-1 expression at the mRNA and protein level in a concentration-dependent fashion. These effects seemed to occur as the result of an inhibition of the Id-1 gene at the promoter level. Importantly, CBD did not inhibit invasiveness in cells that ectopically expressed Id-1. In conclusion, CBD represents the first nontoxic exogenous agent that can significantly decrease Id-1 expression in metastatic breast cancer cells leading to the down-regulation of tumor aggressiveness.

Plant cannabinoids are stable compounds with low-toxicity profiles that are well tolerated by animals and humans during chronic administration. 

If CBD shows efficacy for treatment of metastatic breast cancer in humans, the low toxicity of the compound would make it an ideal candidate for chronic administration.”

Pathways mediating the effects of cannabidiol on the reduction of breast cancer cell proliferation, invasion, and metastasis

“Invasion and metastasis of aggressive breast cancer cells are the final and fatal steps during cancer progression. Clinically, there are still limited therapeutic interventions for aggressive and metastatic breast cancers available. Therefore, effective, targeted, and non-toxic therapies are urgently required. Id-1, an inhibitor of basic helix-loop-helix transcription factors, has recently been shown to be a key regulator of the metastatic potential of breast and additional cancers. We previously reported that cannabidiol (CBD), a cannabinoid with a low toxicity profile, down-regulated Id-1 gene expression in aggressive human breast cancer cells in culture. Using cell proliferation and invasion assays, cell flow cytometry to examine cell cycle and the formation of reactive oxygen species, and Western analysis, we determined pathways leading to the down-regulation of Id-1 expression by CBD and consequently to the inhibition of the proliferative and invasive phenotype of human breast cancer cells. Then, using the mouse 4T1 mammary tumor cell line and the ranksum test, two different syngeneic models of tumor metastasis to the lungs were chosen to determine whether treatment with CBD would reduce metastasis in vivo. We show that CBD inhibits human breast cancer cell proliferation and invasion through differential modulation of the extracellular signal-regulated kinase (ERK) and reactive oxygen species (ROS) pathways, and that both pathways lead to down-regulation of Id-1 expression. Moreover, we demonstrate that CBD up-regulates the pro-differentiation factor, Id-2. Using immune competent mice, we then show that treatment with CBD significantly reduces primary tumor mass as well as the size and number of lung metastatic foci in two models of metastasis. Our data demonstrate the efficacy of CBD in pre-clinical models of breast cancer. The results have the potential to lead to the development of novel non-toxic compounds for the treatment of breast cancer metastasis, and the information gained from these experiments broaden our knowledge of both Id-1 and cannabinoid biology as it pertains to cancer progression.”

No medical benefit from marijuana? How about a cancer cure?

“It’s been known for a long time that THC and other cannabinoids can effectively treat symptoms of cancer sufferers and chemotherapy patients, such as nausea, pain, loss of appetite and fatigue. But what scientists have proven in laboratory experiments and testing on animals the last few years is that cannabinoids also can kill cancer cells and stop the spread of aggressive types of the disease — cancer of the breast, brain, prostate, colon or lungs.

The way cannabinoids work, simply put, is by blocking or deactivating a gene called ID-1 that spreads cancer. One compound that’s been found to be especially effective doing this is called cannabidiol, or CBD.

Also, CBD (which unlike THC is non-psychoactive) and other cannabinoids are non-toxic, which greatly reduces the risk of harmful effects from their use.”

Nonpsychoactive cannabinoids, such as cannabidoil, are particularly advantageous to use because they avoid toxicity that is encountered with psychoactive cannabinoids at high doses useful in the method of the present invention. CBD (Cannabidiol), one of the main constituents of the cannabis plant has been proven medically to relieve many diseases including the inhibition of cancer cell growth. Recent studies have shown it to be an effective atypical anti-psychotic in treating schizophrenia. CBD also interferes with the amount of THC your brain processes, balancing the psychotropic effect of marijuana. That is precisely why the power of raw cannabis is turning heads.”
