Cannabidiol-Induced Apoptosis in Human Leukemia Cells: A Novel Role of Cannabidiol in the Regulation of p22phox and Nox4 Expression

“Marijuana has been suggested as a potent therapeutic agent alleviating such complications as intraocular pressure in glaucoma and cachexia, nausea, and pain in AIDS and cancer patients. A number of recent studies now suggest the possible use of these compounds for the treatment of cannabinoid receptor-expressing tumors…

In the current study, we examined the effects of the nonpsychoactive cannabinoid, cannabidiol, on the induction of apoptosis in leukemia cells. Exposure of leukemia cells to cannabidiol led to cannabinoid receptor 2 (CB2)-mediated reduction in cell viability and induction in apoptosis. Furthermore, cannabidiol treatment led to a significant decrease in tumor burden and an increase in apoptotic tumors in vivo…

Together, the results from this study reveal that cannabidiol, acting through CB2 and regulation of Nox4 and p22phox expression, may be a novel and highly selective treatment for leukemia…

In summary, the current study demonstrates that CBD-induced apoptosis may constitute a novel approach to treat malignancies of the immune system…”

Cannabidiol, unlike synthetic cannabinoids, triggers activation of RBL-2H3 mast cells

“Plant-derived cannabinoids, such as Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD), the main psychoactive and nonpsychoactive components of cannabis, respectively, possess myriad pharmacological properties…

Cannabidiol (CBD), a prominent psychoinactive component of cannabis with negligible affinity for known cannabinoid receptors, exerts numerous pharmacological actions, including anti-inflammatory and immunosuppressive effects…

Together, these results support existence of yet-to-be identified sites of interaction, i.e., receptors and/or ion channels associated with Ca2+ influx of natural cannabinoids such as CBD and THC, the identification of which has the potential to provide for novel strategies and agents of therapeutic interest.”

Gamma-irradiation enhances apoptosis induced by cannabidiol, a non-psychotropic cannabinoid, in cultured HL-60 myeloblastic leukemia cells.

“Two non-psychotropic cannabinoids, cannabidiol (CBD) and cannabidiol-dimethylheptyl (CBD-DMH), induced apoptosis in a human acute myeloid leukemia (AML) HL-60 cell line…

  Caspase-3 activation was observed after the cannabinoid treatment, and may represent a mechanism for the apoptosis.

Our data suggest a possible new approach to treatment of AML.”

Therapeutic potential of cannabinoid medicines.

Drug Testing and Analysis

“Cannabis was extensively used as a medicine throughout the developed world in the nineteenth century but went into decline early in the twentieth century ahead of its emergence as the most widely used illicit recreational drug later that century. Recent advances in cannabinoid pharmacology alongside the discovery of the endocannabinoid system (ECS) have re-ignited interest in cannabis-based medicines.

The ECS has emerged as an important physiological system and plausible target for new medicines. Its receptors and endogenous ligands play a vital modulatory role in diverse functions including immune response, food intake, cognition, emotion, perception, behavioural reinforcement, motor co-ordination, body temperature, wake/sleep cycle, bone formation and resorption, and various aspects of hormonal control. In disease it may act as part of the physiological response or as a component of the underlying pathology.

In the forefront of clinical research are the cannabinoids delta-9-tetrahydrocannabinol and cannabidiol, and their contrasting pharmacology will be briefly outlined. The therapeutic potential and possible risks of drugs that inhibit the ECS will also be considered. This paper will then go on to review clinical research exploring the potential of cannabinoid medicines in the following indications: symptomatic relief in multiple sclerosis, chronic neuropathic pain, intractable nausea and vomiting, loss of appetite and weight in the context of cancer or AIDS, psychosis, epilepsy, addiction, and metabolic disorders.”

Cannabis Can Prevent Cancer Caused By Cigarette Use, According To New Study

tobacco cigarettes marijuana cannabis

“A new study published by the journal J-Stage, and funded by the Ministry of Education, Culture, Sports, Science and Technology of Japan, has found that cannabinoids – whether THC, CBD or CBDV – were effective at blocking a certain enzyme which is known to cause cancer, and is produced in large amount when cigarettes are consumed.”

“These results suggest that the pentylresorcinol structure in CBD may have structurally important roles in direct CYP1A1 inhibition, although the whole structure of CBD is required for overall inhibition”, according to researchers.

CYP1A1 is an enzyme which isn’t dangerous at low-levels, but is produced in large quantities when someone smokes cigarettes; at large doses, the enzyme has been linked to cancer.

Researchers state that; “Accordingly, CBD and its related compounds, which are potent inhibitors of CYP1A1 activity, would be useful as a lead compound in anticancer chemotherapy.””

Curing Cancer with Cannabis

“Repeal Archaic Anti-Marijuana Laws”

cannabis
“Although cannabis has been used in medical treatment for thousands of years in China and India, it became illegal in most of the western world in the first half of the twentieth century. This was thanks to an early corporate conspiracy involving DuPont, William Randolph Hearst, the Mellon Bank and Secretary of the Treasury Andrew Mellon. The major problem with hemp was its immense versatility. Most paper and nearly all plastics were made of hemp fiber, while hemp oil was a major fuel. Dupont was trying to promote their own petroleum-based plastic, Hearst his wood pulp paper factories, and Mellon his friends at Standard Oil. See The Politics of Hemp.

Recent research, mainly out of Spain and Italy (such research is  illegal in the US), reveals that treatment with a cannabis metabolite cannobidiol (CBD) has a marked effect on immune function and is useful in the treatment of breast, bowel and other metastatic cancers, diabetes, epilepsy, glaucoma, high blood pressure, chronic pain and a host of other medical conditions…

Below is a link to a groundbreaking lecture on the medical benefits of cannabis by University of California-San Francisco oncologist/AIDS specialist Donald Abrams, MD. Abrams contends that smoking cannabis actually reduces your chances of lung cancer, owing to its anti-inflammatory and immune effects.

Neuroprotection and reduction of glial reaction by cannabidiol treatment after sciatic nerve transection in neonatal rats.

“The clinical use of neurotrophic factors is difficult due to side effects and elevated costs, but other molecules might be effective and more easily obtained. Among them, some are derived from Cannabis sativa.

Cannabidiol (CBD) is the major non-psychotropic component found on the surface of such plant leaves.

The present study aimed to investigate the neuroprotective potential of CBD…

The present results show that CBD possesses neuroprotective characteristics that may, in turn, be promising for future clinical use.”

Family: medical marijuana could help son with rare disease

 “”Everybody loves Charlie,” boasted father, Eric Byrd,”he’s just always smiling, it’s his personality, he just glows.”

Charlie Byrd looks like every little five-year-old boy and has a smile that will melt your heart. But Charlie is in a dangerous battle for his life against a rare, and even deadly, form of epilepsy called “Dravet Syndrome.”

“He keeps smiling and he doesn’t even know that he’s sick,” said Crystal Byrd, Charlie’s mother, through tears.

The Byrds say the first seizure happened when Charlie was just a few months old, the second came just a few months later when he was six months old. From there the hospital trips added up, as did the pain and the seizures.

“We quit counting, it had become a little hard to deal with,” stated Charlie’s mom.

The Byrds have given their only son everything they can find.

“We’ve tried numerous therapies, medicines, and nothing’s ever worked,” said Eric Byrd, “Today, he’s on four different types of anti-epileptic drugs. This morning he had two seizures in his sleep.”

The West Liberty family even started the young boy on medicine from other countries after doing research. Along the way they connected with other families with children battling “Dravet Syndrome.”

One case stands above the rest. Crystal Byrd pointed to a girl in Colorado who seems to have found a strong remedy, “The child went from 300 seizures to one a week, and sometimes the one-a-week doesn’t even come.”

The medicine, though, is only legal in 19 states and Kentucky isn’t one of them.

“It was the medical marijuana, the CBDs,” answered Crystal.

CBD, or cannabidiol, isn’t like other forms of marijuana, as Crystal explained, she’s not giving her son a cigarette. Instead, she said it can come in the form of an oil or even pill.

“He won’t be high from it, it doesn’t have the taboo marijuana association with it,” she said.

Still, the topic of legalizing marijuana even in medical cases has been, at times, controversial. Yet, it is on the table for politicians to consider in a Wednesday meeting in Frankfort. According to the agenda, advocates for medicinal marijuana, patients, doctors, and even a former narcotics officer will speak before a committee of state lawmakers.

The Byrds are anxious. They say if medical marijuana isn’t allowed, then they might be looking to move to a state that does allow it, like Colorado.

“I can see through conservatory, but I mean how can you look at him and not want to give him a chance?” asked Crystal Byrd.”

Marijuana stops child’s severe seizures

 

“Saundra Young of CNN.com delved into the heated debate of medical marijuana and children, in her story about a little girl who has a rare, and severe form of epilepsy called Dravet Syndrome. While the debate continues, the pro-legalization side may have won a small victory in the form of Charlotte Figi, 6, who was given her life back by marijuana…

Desperate for a treatment, Charlotte’s father Matt searched the Internet and eventually found a boy with a similar case in which medical marijuana helped his seizures. The Figi’s turned to the Stanley brothers, one of Colorado’s largest marijuana growers and dispensary owners, for help.

“These six brothers were crossbreeding a strain of marijuana low in THC, the compound in marijuana that’s psychoactive, and high in CBD, which has medicinal properties but no psychoactivity,” writes Young. But the Stanley brothers didn’t know what to do with this particular strain, as no one seemed to want to buy it. Then they met Charlotte.

The first time Charlotte tried a small dose of cannabis oil, the results were astounding:

“When she didn’t have those three, four seizures that first hour, that was the first sign,” Paige recalled. “And I thought well, ‘Let’s go another hour, this has got to be a fluke.'”

The Stanley brothers started the Realm of Caring Foundation, a nonprofit organization that provides this particular strain of medical marijuana to adults and children suffering from a host of diseases. The strain used by Charlotte and 41 other patients is affectionately called Charlotte’s Web.

Charlotte’s seizures stopped for seven days after her first dose and today she is eating, and walking on her own — even riding a bike, her parents say. Charlotte gets a dose of the cannabis oil twice a day in her food and her seizures are down to 2 to 3 per month.

“I literally see Charlotte’s brain making connections that haven’t been made in years,” Matt said. “My thought now is, why were we the ones that had to go out and find this cure? This natural cure? How come a doctor didn’t know about this? How come they didn’t make me aware of this?”
