Study: Marijuana Compound Can Kill Some Cancer Cells – TIME

Marijuana leaf

“Compounds derived from marijuana can kill cancerous cells in patients with leukemia, according to a recent study.

The study, published in the Anticancer Research journal, was partially funded by GW Pharmaceuticals. which already produces a cannabis-derived drug to help people with multiple sclerosis. Dr. Wai Liu studied six different non-psychoactive cannabinoids (compounds derived from marijuana that don’t get the user high like its THC component does). He found that certain non-psychoactive cannabinoids “resulted in dramatic reductions in cell viability” and “caused a simultaneous arrest at all phases of the cell cycle,” according to the study summary posted online.

Leukemia will take the lives of an estimated 23,720 people this year.

This isn’t the first time marijuana has been linked to deterring cancer: In 2012, researchers at the California Pacific Medical Center in San Francisco found that CBD — a non-psychoactive chemical compound found in cannabis — can stop metastasis in some kinds of aggressive cancer. Liu told the Huffington Post that smoking cannabis is unlikely to have the same cancer-inhibiting effect.”

Study: Cannabis Compounds Can Kill Cancer Cells – US News & World Report

“Researcher says cannabinoids might treat cancer as well as billion-dollar drugs.”

A medical marijuana activist holds a sign during a rally Jan. 4, 2010, in Oakland, Calif. Research suggests marijuana may fight cancer itself, not just side-effects.“A British researcher has found that cannabinoids, a term for chemicals derived from marijuana, can kill leukemia cells, and he expects clinical trials for new medications to begin soon.

The findings, published in the October issue of Anticancer Research: International Journal of Cancer Research and Treatment, show that certain non-psychoactive cannabinoids “resulted in dramatic reductions in cell viability” and “caused a simultaneous arrest at all phases of the cell cycle,” according to an abstract posted online. 

The study tested six cannabinoids, together and independently, on leukemia cells. Study author Wai Liu, an oncologist at the University of London’s St. George’s medical school, told U.S. News the chemicals displayed “potent anti-cancer activity” and, significantly, “target and switch off” pathways that allow cancers to grow.”

Systematic review of the literature on clinical and experimental trials on the antitumor effects of cannabinoids in gliomas.

“To evaluate, through a systematic review of the literature, the antitumoral effects of cannabinoids on gliomas…

  In all experimental studies included, cannabinoids exerted antitumoral activity in vitro and/or antitumoral evidence in vivo in several models of tumor cells and tumors.

The antitumor activity included: antiproliferative effects (cell cycle arrest), decreased viability and cell death by toxicity, apoptosis, necrosis, autophagy, as well as antiangiogenic and antimigratory effects.

 Antitumoral evidence included: reduction in tumor size, antiangiogenic, and antimetastatic effects.

 Additionally, most of the studies described that the canabinnoids exercised selective antitumoral action in several distinct tumor models. Thereby, normal cells used as controls were not affected.

The safety factor in the cannabinoids’ administration has also been demonstrated in vivo.

 The various cannabinoids tested in multiple tumor models showed antitumoral effects both in vitro and in vivo.

 These findings indicate that cannabinoids are promising compounds for the treatment of gliomas.”

Cannabidiol, a non-psychoactive cannabinoid compound, affects metalloproteinases and pro-survival intracellular pathways in u87-mg human glioma cell line

“Malignant gliomas are the most common primary brain tumors… Recently, we have shown that the non-psychoactive cannabinoid compound cannabidiol (CBD) induced apoptosis of human glioma cells in vitro and tumor regression in vivo…the present study was to investigate the anti-migratory action of CBD…

 In conclusion, the present investigation adds further insights into the antitumoral action of the non-psychoactive CBD, showing multiple mechanisms through which the cannabinoid inhibits glioma cell growth and motility.

As CBD is a natural compound without psychotropic and side effects, these data lead us to consider CBD as a new potential anticancer drug useful in the management of gliomas.”

“Our findings support that safe, therapeutically efficacious doses of THC may be reached in cancer patients,” Guillermo Velasco of Complutense University in Madrid and colleagues reported in the Journal of Clinical Investigation…

Other research has shown benefits, such as staving off Alzheimer’s, and many doctors view THC as a valuable way to treat weight loss associated with AIDS, and nausea and vomiting associated with chemotherapy in cancer patients.

Velasco and his team’s study included an analysis of two tumors from two people with a highly aggressive brain cancer which showed signs of autophagy after receiving THC.

The researchers said the findings could pave the way for cannabinoid-based drugs to treat cancer…”

Cannabidiol (CBD) Shown To Kill Breast Cancer Cells

 “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.””

THC Gives Cancer Cells the Munchies Too

“…THC and other cannabinoids are actively being investigated for various useful clinical purposes, including the treatment of cancer through the inhibition of tumor growth.

A new study by Salazar et al. in The Journal of Clinical Investigation demonstrates that THC causes tumor cells to begin to degrade themselves from the inside (a process called autophagy, i.e. “self-eating”). Although autophagy has been shown to promote cell survival in some cases and cell death in others, the authors show that in this case it causes cancer cells to undergo programmed cell death (apoptosis). Thus, THC activates a series of events within cancer cells, inhibiting tumor growth.”

Critical appraisal of the potential use of cannabinoids in cancer management

“Cannabinoids have been attracting a great deal of interest as potential anticancer agents. Originally derived from the plant Cannabis sativa, there are now a number of endo-, phyto- and synthetic cannabinoids available. This review summarizes the key literature to date around the actions, antitumor activity, and mechanisms of action for this broad range of compounds…

Two therapeutic avenues exist for the development of cannabinoids as anticancer agents. As antiemetic and analgesic compounds, this class of compounds has been explored in terms of palliative care. More recently, cannabinoid agonists and antagonists have been screened for potential direct antitumorigenic properties.

… results suggest that overall the cannabinoids affect multiple cellular signaling pathways, which means they have the potential to decrease cancer development, growth, and metastasis.

Overall, the cannabinoids may show future promise in the treatment of cancer, but there are many significant hurdles to be overcome. There is much still to be learned about the action of the cannabinoids and the endocannabinoid system.

It is a distinct possibility that the cannabinoids may have a place in the future treatment of cancer.”
