A biosynthetic pathway for anandamide

Posted on by

“The endocannabinoid arachidonoyl ethanolamine (anandamide) is a lipid transmitter synthesized and released “on demand” by neurons in the brain. Anandamide is also generated by macrophages where its endotoxin (LPS)-induced synthesis has been implicated in the hypotension of septic shock and advanced liver cirrhosis. Anandamide can be generated from its membrane precursor, N-arachidonoyl phosphatidylethanolamine (NAPE) through cleavage by a phospholipase D (NAPE-PLD).

Here we document a biosynthetic pathway for anandamide in mouse brain…

Both PTPN22 and endocannabinoids have been implicated in autoimmune diseases, suggesting that the PLC/phosphatase pathway of anandamide synthesis may be a pharmacotherapeutic target.

The observed exclusive role of the PLC/phosphatase pathway in LPS-induced AEA synthesis may offer therapeutic targets for the treatment of these conditions.

Furthermore, cannabinoids have immunosuppressive effects in autoimmune models of multiple sclerosis and diabetes, and mice deficient in CB1 receptors show increased susceptibility to neuronal damage found in autoimmune encephalitis…”

Study: Marijuana Appears to Slow Cancer Growth in Laboratory Setting -FOXNEWS

Posted on by

“Certain marijuana components may suppress the tumors of highly invasive cancers, a new study finds.

In laboratory tests, cannabinoids, the active components in marijuana, were found to slow the spread of lung and cervical cancer tumors, according to researchers Robert Ramer and Burkhard Hinz of the University of Rostock in Germany.

Proponents of medical marijuana believe that cannabinoids reduce the side effects of cancer treatment, such as pain, weight loss and vomiting.

The study, published in the Jan. 2 issue of the Journal of the National Cancer Institute, finds that the compounds may also have an anticancer effect;

In addition to suppressing tumor cell invasion, cannabinoids also stimulated the expression of TIMP-1, an inhibitor of a group of enzymes involved in tumor cell invasion.

“To our knowledge, this is the first report of TIMP-1-dependent anti-invasive effects of cannabinoids,” the authors wrote. “This signaling pathway may play an important role in the antimetastatic action of cannabinoids, whose potential therapeutic benefit in the treatment of highly invasive cancers should be addressed in clinical trials.””

Cannabidiol (CBD) Shown To Kill Breast Cancer Cells -Cafemom

Posted on by

“Cannabidiol (CBD) has been on the receiving end of a lot of attention from the scientific community for several decades now.

However, it is only now that we are really starting to begin to get a grasp on how wonderful this cannabinoid truly is.

A study from 2011 states that cannabidiol is considered an antineoplastic agent on the basis of its in vitro and in vivo activity against tumor cells. However, the exact molecular mechanism through which CBD works in this capacity is yet to be understood. The study, titled “Cannabidiol Induces Programmed Cell Death in Breast Cancer Cells by Coordinating the Cross-talk between Apoptosis and Autophagy,” focuses on how CBD can kill breast cancer cells. Breast cancer is the second leading cause of cancer-related death in women in the United States.

What the scientists found was that CBD influences apoptosis by interacting with a key protein, called beclin-1, found within the cancerous cell. Beclin-1 is also known to play a key role in autophagy, or cellular self-degradation of non-vital components, which may lead to programmed cell death. This causes a distortion of the electrical signals between the outer mitochondrial membrane and the rest of the cell, disrupting the transfer to the cell interior of certain molecules that are necessary for metabolism. What this means is that the cell cannot transfer energy, and the cell starves to death, and in doing so activates the self-destruction process of apoptosis.

The study concludes by stating, “In summary, we showed that CBD, a plant-derived cannabinoid, preferentially kills breast cancer cells by inducing ER stress, inhibiting mTOR signaling, enhancing ROS generation, and mediating a complex balance between autophagy and mitochondria-mediated apoptosis in MDA-MB-231 breast cancer cells. These findings support the continued exploration of CBD as an alternative agent for breast cancer treatment.””

The role of the endocannabinoid system in atherosclerosis.

Posted on by

“Our current understanding of the pathophysiology of atherosclerosis suggests a prominent role for immune responses from its initiation through its complications. Given the increasing prevalence of cardiovascular risk factors worldwide, there is an urgent need to better understand the underlying mechanisms to improve current treatment protocols.

A growing body of evidence suggests that endocannabinoid signalling plays a critical role in the pathogenesis of atherogenesis and its clinical manifestations. Blocking CB(1) receptors has been shown to mediate not only weight reduction, but also several cardiometabolic effects in rodents and humans, indicating a potential relevance for the process of atherosclerosis.

Activation of CB(2) receptors with Delta(9)-tetrahydrocannabinol (THC) has been shown to inhibit atherosclerotic plaque progression in mice, mainly by inhibiting macrophage recruitment.

In conclusion, the precise role of the endocannabinoid system during atherosclerosis is not yet understood.”

Cannabinoid receptors in atherosclerosis.

Posted on by

“…cannabinoid receptors are potential targets for the treatment of atherosclerosis…

Cannabinoids, such as Delta9-tetrahydrocannabinol, the major psychoactive compound of marijuana… was shown to inhibit disease progression through pleiotropic effects on inflammatory cells.

The development of novel cannabinoid receptor ligands that selectively target CB2 receptors or pharmacological modulation of the endocannabinoid system might offer novel therapeutic strategies in the treatment of atherosclerosis.

The immunomodulatory capacity of cannabinoids is now well established and suggests a broad therapeutic potential of cannabinoids for a variety of conditions, including atherosclerosis.”

Cannabinoid receptors in acute and chronic complications of atherosclerosis

Posted on by

“Atherosclerosis is a chronic inflammatory disease that is the primary cause of myocardial infarction and stroke, which occur after sudden thrombotic occlusion of an artery.

A growing body of evidence suggests that cannabinoid signalling plays a fundamental role in atherosclerosis development and its clinical manifestations. Thus, CB2 receptors are protective in myocardial ischaemia/reperfusion and implicated in the modulation of chemotaxis, which is crucial for the recruitment of leukocytes during inflammation.

Delta-9-Tetrahydrocannabinol (THC)-mediated activation has been shown to inhibit atherosclerotic plaque progression in a CB2 dependent manner.

It is tempting to suggest that pharmacological modulation of the endocannabinoid system is a potential novel therapeutic strategy in the treatment of atherosclerosis.”

Towards a therapeutic use of selective CB2 cannabinoid receptor ligands for atherosclerosis.

Posted on by

“Atherosclerosis remains the primary cause of heart disease and stroke, causing approximately 50% of all deaths in Western countries. The identification of promising novel anti-atherosclerotic therapies is therefore of great interest and represents a continued challenge to the medical community.

Cannabinoids, such as Delta9-tetrahydrocannabinol (THC), which is the major psychoactive compound of marijuana, modulate immune functions and might therefore be of therapeutic use for the treatment of inflammatory diseases.

The authors have demonstrated recently that oral treatment with low dose THC inhibits atherosclerosis progression in mice through pleiotropic immunomodulatory effects on inflammatory cells. All these effects were mediated via the cannabinoid receptor CB(2), the main cannabinoid receptor expressed on immune cells.

The identification and characterization of cannabinoid derivative that selectively activate CB(2) receptors and are devoid of adverse effects might offer a novel therapeutic strategy for the treatment of atherosclerosis.”

CBD-Rich Marijuana Fights Colon Cancer, New Study Finds

Posted on by

“In 2008, over one million individuals were diagnosed with colon cancer, also known as colorectal cancer or bowel cancer and it caused over 600,000 deaths globally. The results of a study published in the journal Phytomedicine in October 2013 suggest that a botanical extract made from high-CBD (cannabidiol) cannabis can selectively target colon cancer cells, while leaving healthy cells unharmed.

Researchers were able to reduce tumor growth and pre-cancerous lesions in mice with colon cancer using the pot molecule CBD as part of a “botanical drug substance”. The authors believe that CBD’s benefits as demonstrated by the results of the study could have clinical relevance for the use of cannabis-based medicines in cancer patients.

Current colon cancer treatments are not only very toxic but also fail to prevent the progression of the disease in some patients. Disease incidence and mortality have not reduced using screening strategies for colon cancer.

Researchers have made progress in investigating cannabis as a treatment for breast and brain cancers considering its antiproliferative CB1 and CB2-mediated effects in colorectal cancer cells and action in experimental models of colon cancer. The study was partially funded through grants from GW Pharmaceuticals and lead by researchers from Italy and the UK.”

The case for assessing cannabidiol in epilepsy.

Posted on by

“Intractable epilepsies have an extraordinary impact on cognitive and behavioral function and quality of life, and the treatment of seizures represents a challenge and a unique opportunity. Over the past few years, considerable attention has focused on cannabidiol (CBD), the major nonpsychotropic compound of Cannabis sativa.

Basic research studies have provided strong evidence for safety and anticonvulsant properties of CBD. However, the lack of pure, pharmacologically active compounds and legal restrictions have prevented clinical research and confined data on efficacy and safety to anecdotal reports.

Pure CBD appears to be an ideal candidate among phytocannabinoids as a therapy for treatment-resistant epilepsy.

A first step in this direction is to systematically investigate the safety, pharmacokinetics, and interactions of CBD with other antiepileptic drugs and obtain an initial signal regarding efficacy at different dosages. These data can then be used to plan double-blinded placebo-controlled efficacy trials.”
