Marijuana May Fight Lung Tumors – CBSNews

Posted on by

“the active ingredient in marijuana may help combat lung cancer, new research suggests.

Moreover, other early research suggests the cannabis compound could help fight brain, prostate, and skin cancers as well, Preet says.

The finding builds on the recent discovery of the body’s own cannabinoid system, Preet says. Known as endocannabinoids, the natural cannabinoids stimulate appetite and control pain and inflammation.

THC seeks out, attaches to, and activates two specific endocannabinoids that are present in high amounts on lung cancer cells, Preet says. This revs up their natural anti-inflammatory properties. Inflammation can promote the growth and spread of cancer.

In the new study, the researchers first demonstrated that THC inhibited the growth and spread of cells from two different lung cancer cell lines and from patient lung tumors. Then, they injected THC into mice that had been implanted with human lung cancer cells. After three weeks, tumors shrank by about 50 percent, compared with tumors in untreated mice.”

Marijuana Fights Cancer

Posted on by

“Marijuana Fights Cancer, Cristina Sanchez, a young biologist at Complutense University in Madrid, was studying cell metabolism when she noticed something peculiar. She had been screening brain cancer cells because they grow faster than normal cell lines and thus are useful for research purposes. But the cancer cells died each time they were exposed to tetrahydrocannabinol (THC), the principal psychoactive ingredient of marijuana.”

Cannabinoids: A new hope for breast cancer therapy?

Posted on by

“Experimental evidence accumulated during the last decade supports that cannabinoids, the active components of Cannabis sativa and their derivatives, possess anticancer activity… these compounds exert anti-proliferative, pro-apoptotic, anti-migratory and anti-invasive actions in a wide spectrum of cancer cells… Moreover, tumor growth, angiogenesis and metastasis are hampered by cannabinoids… our current knowledge on the anti-tumor potential of cannabinoids in breast cancer… suggests that cannabinoid-based medicines may be useful for the treatment of most breast tumor subtypes.”

“Cannabinoid receptor agonists have gained attention as potential therapeutic targets of inflammatory and neuropathic pain. Here, we report the identification and optimization of a series of 7-oxo-[1,4]oxazino[2,3,4-ij]quinoline-6-carboxamide derivatives as a novel chemotype of selective cannabinoid CB2 receptor agonists… 7-Oxo-[1,4]oxazino[2,3,4-ij]quinoline-6-carboxamides as Selective CB2 Cannabinoid Receptor Ligands: Structural Investigations around a Novel Class of Full Agonists.”

Cannabidiol protects oligodendrocyte progenitor cells from inflammation-induced apoptosis by attenuating endoplasmic reticulum stress

Posted on by

“Cannabidiol (CBD) is the most abundant cannabinoid in Cannabis sativa that has no psychoactive properties. CBD has been approved to treat inflammation, pain and spasticity associated with multiple sclerosis (MS), of which demyelination and oligodendrocyte loss are hallmarks. Thus, we investigated the protective effects of CBD against the damage to oligodendrocyte progenitor cells (OPCs) mediated by the immune system… Cannabidiol protects oligodendrocyte progenitor cells… These findings suggest that attenuation of the ER stress pathway is involved in the ‘oligoprotective’ effects of CBD during inflammation.”

Cannabinoids for gastrointestinal diseases: potential therapeutic applications

Posted on by

“…pharmacological modulation of the endogenous cannabinoid system could provide new therapeutics for the treatment of a number of gastrointestinal diseases, including nausea and vomiting, gastric ulcers, irritable bowel syndrome, Crohn’s disease, secretory diarrhoea, paralytic ileus and gastroesophageal reflux disease. Some cannabinoids are already in use…”

Alternative targets within the endocannabinoid system for future treatment of gastrointestinal diseases

Posted on by

“Alternative targets within the endocannabinoid system for future treatment of gastrointestinal diseases… Many beneficial effects of herbal cannabinoids on gut motility and inflammation have been demonstrated, suggesting a vast potential for these compounds in the treatment of gastrointestinal disorders….endocannabinoid system’ (ECS), a cooperating network of molecules that regulate themetabolism of the body’s own and of exogenously administered cannabinoids. The ECS… offering many potential targets for pharmacological intervention. Of major therapeutic interest are nonpsychoactive cannabinoids that do not directly target cannabinoid receptors but still possess cannabinoid-like properties… promising alternative therapeutic tools to manipulate the ECS.”

Concomitant consumption of marijuana, alcohol and tobacco in oral squamous cell carcinoma development and progression: Recent advances and challenges

Posted on by

“Carcinogens found in tobacco are also concentrated in marijuana, but the latter also contains high levels of cannabinoids, bioactive compounds responsible for several effects such as euphoria and analgesia. However, Δ(9)-tetrahydrocannabinol (Δ(9)-THC), the major psychotropic cannabinoid found in plants, causes a reduction of cellular metabolism and induction of apoptosis (progarmmed cell death), both of which are anti-neoplastic properties…”
