“Cannabinoid Δ9-tetrahydrocannabinol (THC) is effective in treating osteoarthritis (OA)…

Activation of cannabinoid receptor CB2 reduces inflammation; whether the activation CB2 is involved in THC-induced therapeutic action for OA is still unknown.

We hypothesized that the activation of CB2 is involved in THC-induced anti-inflammation in the MG-63 cells exposed to LPS, and the anti-inflammation is mediated by cofilin-1…

We found that THC suppressed the release of proinflammatory factors, including tumor necrosis factor α (TNF-α), interleukin- (IL-) 1β, IL-6, and IL-8, decreased nuclear factor-κB (NF-κB) expression, and inhibited the upregulation of cofilin-1 protein in the LPS-stimulated MG-63 cells.

These results suggested that CB2 is involved in the THC-induced anti-inflammation in LPS-stimulated MG-63 cells, and the anti-inflammation may be mediated by cofilin-1.”

“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 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.”

“The endocannabinoid system plays an important role in numerous physiological processes and represents a potential drug target for diseases ranging from brain disorders to cancer…

In the aging skeleton, CB1 deficiency causes accelerated osteoporosis characterized mainly by a significant reduction in bone formation coupled to enhanced adipocyte accumulation in the bone marrow.

A similar acceleration of bone loss was also reported in aging CB2-deficient mice but found to be associated with enhanced bone turnover.

This perspective describes the role of cannabinoid ligands and their receptors in bone metabolism and highlights the promise and dilemma of therapeutic exploitation of the endocannabinoid system for treatment of bone disorders.”

“Migration and differentiation of mesenchymal stem cells (MSCs) are known to be involved in various regenerative processes such as bone healing.

The present study therefore focussed on cannabinoids which have been demonstrated to exhibit tissue healing properties…

Collectively, this study demonstrates CBD to promote the migration of MSCs via activation of the CB2 receptor and inhibition of GPR55 and to induce osteoblastic differentiation. CBD may therefore recruit MSCs to sites of calcifying tissue regeneration and subsequently support bone regeneration via an osteoanabolic action on MSCs.”

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 Ingredient Can Help Cancer Patients Regain Their Appetites And Sense Of Taste

“The active ingredient in cannabis can improve the appetites and sense of taste in cancer patients, according to a new study published online in the cancer journal, Annals of Oncology  today.

Loss of appetite is common among cancer patients, either because the cancer itself or its treatment affects the sense of taste and smell, leading to decreased enjoyment of food. This, in turn, can lead to weight loss, anorexia, a worse quality of life and decreased survival; therefore, finding effective ways of helping patients to maintain a good diet and consume enough calories is an important aspect of their treatment.

The majority of THC-treated patients (64%) had increased appetite, three patients (27%) showed no change, and one patient’s data was incomplete. No THC-treated patients showed a decrease in appetite. By contrast, the majority of patients receiving placebo had either decreased appetite (50%) or showed no change (20%).

Although there was no difference in the total number of calories consumed by both groups, the THC-treated patients tended to increase the proportion of protein that they ate, and 55% reported that savoury foods tasted better, whereas no patients in the placebo group reported an increased liking for these foods. (Cancer patients often find that meat smells and tastes unpleasant and, therefore, they eat less of it).

In addition, THC-treated patients reported better quality of sleep and relaxation than in the placebo group.”

“Four years following resection of a Clark’s level IV malignant melanoma, a 50-year-old man developed widespred metastatic disease involving the liver, bones, brain, gastrointestinal mucosa, and lungs. One week after whole brain radiation therapy, he was admitted to the hospital for nausea, vomiting, and pain.

He was treated with several antiemetic drugs, but it was not until dronabinol was added that the nausea and vomiting stopped.

Dronabinol was an effective antiemetic used in combination with prochlorperazine in nausea and vomiting unresponsive to conventional antiemetics.”

“Cannabis oil, which cancer-sufferers credit with saving their lives, and which is supposedly useful in healing other ailments, from diabetes to skin rashes, is made by distilling raw bud down to its essential ingredients.”

“First it was a cough. Then it was bronchitis. Then it was time to say goodbye to Michelle Aldrich.

The year 2011 was supposed to be a good one for the 66-year-old. That June, she and her husband, Michael, were feted with a lifetime achievement award by High Times magazine for their four decades of work on marijuana legalization. Yet something was off. She was smoking a lot, maybe more than ever.

And she couldn’t get high.

In the fall of that year — a bad time for the local marijuana movement, as the federal Justice Department began shutting down hundreds of California medical cannabis dispensaries — Aldrich went in to see a series of doctors for what she thought was a flu that just refused to go away.

After six weeks of progressively worse diagnoses — flu became bronchitis, which became pneumonia — a CT scan revealed the cause behind the “heat” she felt in the middle of her chest. A tumor, “poorly-differentiated non-small cell adenocarcinoma.” In other words, stage 3 lung cancer.

Lung cancer is a killer, with nearly 70 percent of new cases resulting in deaths, according to statistics published by the National Cancer Institute. “I thought I was going to die,” Aldrich says from her Marina District apartment. But she didn’t. And now, she is busy telling anyone who will listen that, along with diet and chemotherapy, a concoction of highly concentrated cannabis oil eliminated her cancer in less than four months.”

Fighting Cancer: Another Study Reveals the Cannabis and Cancer Prevention Link

“Does marijuana cause cancer? Revealing the link between cannabis and cancer yet again, researchers with the California Pacific Medical Center in San Francisco have released findings that further bolster cannabis as an anti-cancer solution.
The researchers have found a compound in the much-talked-about plant could “halt the spread” of many types of aggressive cancers, including breast cancer.

The Cannabis and Cancer Link

Cannabidiol is the compound, and while it fights cancer cells, it does not produce the high feelings commonly associated with cannabis. Instead, it seems to “switch off” the gene responsible for metastasizing breast cancer.

They reportedly found the compound doesn’t only stop the breast cancer cells from growing, but even causes them to return back to normal cells, cancer-free.”
