“New research from the University of London suggests chemicals in marijuana could be used to fight leukemia.

Published online in Anticancer Research, researchers at the Department of Oncology at St. George’s, University of London studied six different cannabinoids and found each to have anti-cancer action in leukemia cells.

Lead author Wai Liu, Ph.D explained the results of the latest study in Monday’s press release.

These agents are able to interfere with the development of cancerous cells, stopping them in their tracks and preventing them from growing. In some cases, by using specific dosage patterns, they can destroy cancer cells on their own.

The scientists were able to replicate previous findings on the anti-cancer effects of THC – the compound in marijuana responsible for the high.

However, in the latest study, Dr. Liu’s team decided to focus on cannabinoids that lacked psychoactive activity, including cannabidiol (CBD), cannabigerol (CBG) and cannabigevarin (CBGV).

This study is a critical step in unpicking the mysteries of cannabis as a source of medicine. The cannabinoids examined have minimal, if any, hallucinogenic side effects, and their properties as anti-cancer agents are promising.

The non-psychoactive cannabinoids were shown to inhibit growth of leukemia cells at all stages of the cell cycle. Interestingly, the team observed even greater effects when different cannabinoids were administered together.

“These compounds are inexpensive to produce”

Dr. Liu says drugs derived from cannabis are much cheaper to produce than traditional cancer therapies. He also thinks they could be combined with existing treatments to enhance their effects.

Used in combination with existing treatment, we could discover some highly effective strategies for tackling cancer. Significantly, these compounds are inexpensive to produce and making better use of their unique properties could result in much more cost effective anti-cancer drugs in future.

Dr. Liu’s next study will investigate the potential of cannabinoids when combined with existing treatments as well as different treatment schedules that could maximize their anti-cancer activity.”

Targeting CB2-GPR55 Receptor Heteromers Modulates Cancer Cell Signaling.

“The G protein-coupled receptors CB2 (CB2R) and GPR55 are overexpressed in cancer cells and human tumors. As a modulation of GPR55 activity by cannabinoids has been suggested, we analyzed whether this receptor participates in cannabinoid effects on cancer cells.

Here, we show that CB2R and GPR55 form heteromers in cancer cells, that these structures possess unique signaling properties, and that modulation of these heteromers can modify the antitumoral activity of cannabinoids in vivo.

These findings unveil the existence of previously unknown signaling platforms that help explain the complex behavior of cannabinoids and may constitute new targets for therapeutic intervention in oncology.”

Targeting multiple cannabinoid antitumor pathways with a resorcinol derivative leads to inhibition of advanced stages of breast cancer.

“The psychoactive cannabinoid Δ9 -tetrahydrocannabinol (THC) and the non-psychoactive cannabinoid cannabidiol(CBD) can both reduce cancer progression each through distinct antitumor pathways.

Our goal was to discover a compound that could efficiently target both cannabinoid antitumor pathways.

KEY RESULTS:

CBD reduced breast cancer metastasis in advanced stages of the disease as the direct result of down-regulating the transcriptional regulator Id1. However, this was associated with moderate increases in survival. We therefore screened for analogs that could co-target cannabinoid antitumor pathways (CBD- and THC-associated) and discovered the compound O-1663. This analog inhibited Id1, produced a marked stimulation of ROS, upregulated autophagy, and induced apoptosis. Of all compounds tested, it was the most potent at inhibiting breast cancer cell proliferation and invasion in culture and metastasis in vivo.

CONCLUSIONS AND IMPLICATIONS:

O-1663 prolonged survival in advanced stages of breast cancer metastasis. Developing compounds that can simultaneously target multiple cannabinoid antitumor pathways efficiently may provide a novel approach for the treatment of patients with metastatic breast cancer.”

Cannabis oil from marijuana is having success treating COPD

COPD

“COPD is the often used term for “Chronic Obstructive Pulmonary Disease,” a rather clumsy and vague description for most of us. It includes a few different lung issues, such as emphysema, bronchiectasis and chronic bronchitis. The scary part is that it’s a mystery to our pharmaceutical-dependent medical system. And it gets progressively worse, often leading to death.

It’s third in disease death rates, behind only heart disease and cancer. COPD creates constricted airways in one’s lungs or renders small lung sacks inelastic and unable to fully accommodate breathing cycles; thus, there is obstruction.

COPD symptoms include some or all of the following: losing one’s breath with minor activity, chronic coughing, increased sputum, chest tightness or pain with difficulty breathing, increased lung infections and fatigue. It has been observed to have four stages. Many of those lugging oxygen canisters around are in the last two stages.

The pharmaceuticals prescribed for treating symptoms often have side effects that cause more problems. Big Pharma is still fishing for cures, while COPD diagnoses rates continue rising in our toxic environment.

Medical marijuana to the rescue once again

The treatment situation is so bleak and harmful with mainstream medicine that those desperate to breathe normally and cough up less mucus have desperately turned to medical marijuana for at least some relief without negative side effects.

Smoking marijuana cigarettes is shunned for obvious reasons, but many claim that vaping, or using a vaporizer to inhale cannabis, is useful for COPD without exacerbating the lungs’ inflammatory condition.

But better results have been achieved by ingesting cannabis, especially the potent, highly condensed oil extract that Rick Simpson pioneered in Canada and now in Eastern Europe. Many medical marijuana advocates, especially those in medical-cannabis-friendly states, have learned to make the oil and provide it to those in need.

Most of the cannabis treatment publicity has gone toward cancer, Crohn’s disease, chronic epileptic seizures and glaucoma. Even Parkinson’s disease and multiple sclerosis victims have experienced positive results from various cannabis products with THC applications.

Pharmaceutical-dependent mainstream medicine hasn’t been able to cure any of these diseases or even alleviate symptoms without creating complications, some fatal.

More COPD patients have hopped on the cannabis cure bandwagon with positive results lately. These results include folks with late-stage COPD and severe emphysema.

An anecdotal sampling

At the relatively young age of 36, Jeff Waters was diagnosed with COPD. Eight years later he had to be rushed to an ER during another bout with bronchitis.

Lung scarring was discovered, and his condition was raised to stage 2 COPD. While prescribing several pharmaceuticals, the doctor told him that it would continue to get worse and eventually kill him.

Jeff did continue to get worse. He was unable to climb a flight of stairs and he wound up with stage 3 COPD and an oxygen canister to prove it. Showering and shaving without his oxygen supply turned out to be almost too arduous of a task.

Then an allergic reaction to a prescribed high blood pressure medication put him on life support in ICU with severe pneumonia for a month. After his recovery, he resolved to handle his COPD without mainstream medical interventions.

Jeff found COPD sufferers online who had resolved their COPD issues with cannabis oil. He networked with them and found his own sources for cannabis oil.

After only two months of using the oil, Jeff went off oxygen and all the pharmaceuticals he had been prescribed. He now walks two to five miles daily and claims that cannabis oil has allowed him “to get his life back.””

“Smoking marijuana has been shown to relieve muscle tightness, called spasticity, and painful symptoms in patients with multiple sclerosis, who have been resistant to conventional MS therapies, according to a new study.

“We found that smoked cannabis was superior to placebo in reducing symptoms and pain in patients with treatment-resistant spasticity, or excessive muscle contractions,” Researcher Dr. Jody Corey-Bloom, director of the University of California, San Diego Multiple Sclerosis Center said in a journal news release.”

Role of ionotropic cannabinoid receptors in peripheral antinociception and antihyperalgesia

Figure 1

“Although cannabinoids have been used for millennia for treating pain and other symptoms, their mechanisms of action remain obscure.

With the heralded identification of multiple G-protein-coupled receptors (GPCRs) mediating cannabinoid effects nearly two decades ago, the mystery of cannabinoid pharmacology was thought to be solved…

Despite the wealth of information on cannabinoid-induced peripheral antihyperalgesic and antinociceptive effects in many pain models, the molecular mechanism(s) for these actions remains unknown.

Although metabotropic cannabinoid receptors have important roles in many pharmacological actions of cannabinoids, recent studies have led to the recognition of a family of at least five ionotropic cannabinoid receptors (ICRs). The known ICRs are members of the family of transient receptor potential (TRP) channels and include TRPV1, TRPV2, TRPV4, TRPM8 and TRPA1.

Cannabinoid activation of ICRs can result in desensitization of the TRPA1 and TRPV1 channel activities, inhibition of nociceptors and antihyperalgesia and antinociception in certain pain models.

Thus, cannabinoids activate both metabotropic and ionotropic mechanisms to produce peripheral analgesic effects.”

TRP Channel Cannabinoid Receptors in Skin Sensation, Homeostasis, and Inflammation.

“In the skin, cannabinoid lipids, whether of endogenous or exogenous origin, are capable of regulating numerous sensory, homeostatic and inflammatory events.

Although many of these effects are mediated by metabotropic CB receptors, a growing body of evidence has revealed that multiple members of the transient receptor potential (TRP) ion channel family can act as “ionotropic cannabinoid receptors”.

Furthermore, many of these same TRP channels are intimately involved in cutaneous processes that include the initiation of pain, temperature, and itch perception, the maintenance of epidermal homeostasis, the regulation of hair follicles and sebaceous glands, and the modulation of dermatitis.

Ionotropic cannabinoid receptors therefore represent potentially attractive targets for the therapeutic use of cannabinoids to treat sensory and dermatological diseases.

Furthermore, the interactions between neurons and other cell types that are mediated by cutaneous ionotropic cannabinoid receptors are likely to be recapitulated during physiological and pathophysiological processes in the central nervous system and elsewhere, making the skin an ideal setting in which to dissect general complexities of cannabinoid signaling.”

Role of Endocannabinoid Activation of Peripheral CB1 Receptors in the Regulation of Autoimmune Disease.

“The impact of the endogenous cannabinoids (AEA, 2-AG, PEA, and virodamine) on the immune cell expressed cannabinoid receptors (CB1, CB2, TRPV-1, and GPR55) and consequent regulation of immune function is an exciting area of research with potential implications in the prevention and treatment of inflammatory and autoimmune diseases.

Despite significant advances in understanding the mechanisms through which cannabinoids regulate immune functions, not much is known about the role of endocannabinoids in the pathogenesis or prevention of autoimmune diseases.

Inasmuch as CB2 expression on immune cells and its role has been widely reported, the importance of CB1 in immunological disorders has often been overlooked especially because it is not highly expressed on naive immune cells.

Therefore, the current review aims at delineating the effect of endocannabinoids on CB1 receptors in T cell driven autoimmune diseases. This review will also highlight some autoimmune diseases in which there is evidence indicating a role for endocannabinoids in the regulation of autoimmune pathogenesis.

Overall, based on the evidence presented using the endocannabinoids, specifically AEA, we propose that the peripheral CB1 receptor is involved in the regulation and amelioration of inflammation associated with autoimmune diseases.”

Marijuana can treat autoimmune diseases, scientific study states

“Weed enthusiasts are getting their case for nationwide decriminalization of marijuana bolstered considerably by a new scientific study that promises the controversial plant can treat multiple medical maladies.

Scientists at the University of South Carolina have discovered marijuana’s potential to treat autoimmune diseases — such as arthritis, lupus, colitis and multiple sclerosis — in which chronic inflammation plays a pivotal role.

The Journal of Biological Chemistry published the researchers’ findings that state marijuana’s potential key role in fighting these diseases lies in its capacity to suppress certain immune functions, most particularly inflammation.

The study examined whether marijuana’s main active constituent, tetrahydrocannabinol (THC), could affect DNA through “epigenetic” pathways.

The group of molecules with the capacity to alter DNA and the functioning of genes it controls is collectively referred to as the epigenome. It includes a group of molecules called histones, which are responsible for inflammation, both beneficial and harmful.

The research team, led by Mitzi Nagarkatti, Prakash Nagarkatti and Xiaoming Yang, found that THC can, indeed, affect DNA expression through epigenetic pathways by altering histones.

As recreational and medical use of marijuana become more acceptable in developed countries, more research is being conducted and more potential health applications are being uncovered.

Marijuana already has a variety of medical uses including treatment of chronic pain, nausea, vomiting and the wasting syndrome experienced by some AIDS patients.”

Autoimmune Diseases Could be Treated With Medical Marijuana

More findings of the medical benefits of marijuana could result in a universal legalization of the drug.

“Researchers at the University of South Carolina conducted a study that analyzed the effects of THC in marijuana on patients with autoimmune diseases because the drug has previously shown to have an immunomodulatory activity.

Immunomodulatory means something is capable of modifying or regulating one or more immune functions, or can provide an immunologic adjustment, regulation, or potentiation. In this study’s case, the researchers found that the application of marijuana has the ability to suppress an immune response to treat autoimmune diseases, such as arthritis, lupus, colitis, multiple sclerosis, and others.”
