Cannabis oil stopped my cancer says Lake Macquarie’s Susannah Patch

Posted on by

“A LAKE Macquarie woman whose ‘‘aggressive’’ breast cancer spread to various parts of her body including her spine and lungs credits her remarkable recovery to cannabis oil.

Awaba woman Susannah Patch, 44, is one of a growing number of Hunter people who have treated themselves using an underground network of cannabis oil suppliers.

Although she had surgery, radiotherapy and chemotherapy, Ms Patch says most of her improvement has come since stopping chemotherapy against the advice of the cancer specialists and continuing with cannabis oil…

‘It is a distinct possibility that the cannabinoids may have ‘‘a place in the future treatment of cancer,’’

Colon carcinogenesis is inhibited by the TRPM8 antagonist cannabigerol, a Cannabis-derived non-psychotropic cannabinoid.

Posted on by

“Cannabigerol (CBG) is a safe non-psychotropic Cannabis-derived cannabinoid which interacts with specific targets involved in carcinogenesis…

Here, we investigated whether CBG protects against colon tumorigenesis.

In vivo, CBG inhibited the growth of xenograft tumors as well as chemically-induced colon carcinogenesis.

CBG hampers colon cancer progression in vivo and selectively inhibits the growth of colorectal cancer cells, an effect shared by other TRPM8 antagonists.

CBG should be considered translationally in colorectal cancer prevention and cure.”

Δ(9)-tetrahydrocannabinol targeting estrogen receptor signaling: the possible mechanism of action coupled with endocrine disruption.

Posted on by

“Δ(9)-Tetrahydrocannabinol (Δ(9)-THC), a biologically active constituent of marijuana, possesses a wide variety of pharmacological and toxicological effects (e.g., analgesia, hypotension, reduction of inflammation, and anti-cancer effects).

Among Δ(9)-THC’s biological activities, its recognized anti-estrogenic activity has been the subject of investigations.

… Δ(9)-THC is used as both a drug of abuse (marijuana) and as a preventive therapeutic to treat pain and nausea in cancer patients undergoing chemotherapy…

…important to investigate the mechanistic basis underlying the anti-estrogenic activity of Δ(9)-THC…

We have recently reported that ERβ, a second type of ER, is involved in the Δ(9)-THC abrogation of E2/ERα-mediated transcriptional activity. Here we discuss the possible mechanism(s) of the Δ(9)-THC-mediated disruption of E2/ERα signaling by presenting our recent findings as well.”

CANNABINOIDS INCREASE LUNG CANCER CELL LYSIS BY LYMPHOKINE-ACTIVATED KILLER CELLS VIA UPREGULATION OF ICAM-1.

Posted on by

“Cannabinoids have been shown to promote the expression of the intercellular adhesion molecule 1 (ICAM-1) on lung cancer cells as part of their anti-invasive and antimetastatic action…

Cannabidiol (CBD), a non-psychoactive cannabinoid, enhanced the susceptibility of cancer cells to adhere to and subsequently lysed by LAK cells, with both effects being reversed by a neutralizing ICAM-1 antibody…

ICAM-1-dependent pro-killing effects were further confirmed for the phytocannabinoid Δ9-tetrahydrocannabinol (THC) and R(+)-methanandamide, a stable endocannabinoid analogue…

Altogether, our data demonstrate cannabinoid-induced upregulation of ICAM-1 on lung cancer cells to be responsible for increased cancer cell susceptibility to LAK cell-mediated cytolysis.

These findings provide proof for a novel antitumorigenic mechanism of cannabinoids.”

Anti-Cancer Effects In Active Component Of Marijuana

Posted on by

“Guillermo Velasco and colleagues, at Complutense University, Spain, have provided evidence that suggests that cannabinoids such as the main active component of marijuana (THC) have anticancer effects on human brain cancer cells.

In the study, THC was found to induce the death of various human brain cancer cell lines and primary cultured human brain cancer cells by a process known as autophagy. Consistent with the in vitro data, administration of THC to mice with human tumors decreased tumor growth and induced the tumor cells to undergo autophagy.

As analysis of tumors from two patients with recurrent glioblastoma multiforme (a highly aggressive brain tumor) receiving intracranial THC administration showed signs of autophagy, the authors suggest that cannabinoid administration may provide a new approach to targeting human cancers.”

However, the underlying mechanism is still under debate. In the present study the impact of cannabinoids on potential tumor-to-endothelial cell communication conferring anti-angiogenesis was studied…

Collectively, our data suggest a pivotal role of the anti-angiogenic factor TIMP-1 inintercellular tumor-endothelial cell communication resulting in anti-angiogenic features of endothelial cells.”

Cannabis May Help Combat Cancer-causing Herpes Viruses

Posted on by

ScienceDaily: Your source for the latest research news

“The compound in marijuana that produces a high, delta-9 tetrahydrocannbinol or THC, may block the spread of several forms of cancer causing herpes viruses, University of South Florida College of Medicine scientists report.

The findings, published Sept. 15 in the online journal BMC Medicine, could lead to the creation of antiviral drugs based on nonpsychoactive derivatives of THC.

The gamma herpes viruses include Kaposi’s Sarcoma Associated Herpes virus, which is associated with an increased risk of cancer that is particularly prevalent in AIDS sufferers. Another is Epstein-Barr virus, which predisposes infected individuals to cancers such as Burkitt’s lymphoma and Hodgkin’s disease.

Once a person is infected, these viruses can remain dormant for long periods within white blood cells before they burst out and begin replicating. This reactivation of the virus boosts the number of cells infected thereby increasing the chances that the cells will become cancerous.

The USF team, led by virologist Peter Medveczky, MD, found that this sudden reactivation was prevented if infected cells were grown in the presence of THC. While cells infected with a mouse gamma herpes virus normally died when the virus was reactivated, these same cells survived when cultured in the laboratory along with the cannabinoid compound – further evidence that THC prevents viral reactivation.

Furthermore, the researchers showed that THC acts specifically on gamma herpes viruses. The chemical had no effect on another related virus, herpes simplex-1, which causes cold sores and genital herpes.

Small concentrations of THC were more potent and selective against gamma herpes viruses than the commonly used antiviral drugs acyclovir, gancicyclovir and foscamet, said Dr. Medveczky, a professor in the Department of Medical Microbiology and Immunology.

The USF researchers suggest that THC selectively inhibits the spread of gamma herpes viruses by targeting a gene these viruses all share called ORF50.”

The Inhibitory Effects of Cannabidiol on Systemic Malignant Tumors

Posted on by

“Cannabidiol may attenuate tumor growth in a number of other systemic malignancies.

Decreased tumor growth in pulmonary malignancies is seen after administration of cannabidiol.

Tumor metastasis also is markedly attenuated.

Similar attenuation of tumor growth is seen in breast malignancies.

The above examples clearly illustrate the significant antineoplastic effects of cannabidiol.

Hopefully, the next few years will see increased studies to fully and further evaluate these antineoplastic effects.”

COX-2 and PPAR-γ confer cannabidiol-induced apoptosis of human lung cancer cells.

Posted on by

Figure 7.

“Within the last decade, evidence has been accumulated to suggest an antitumorigenic action of cannabinoids elicited via induction of apoptosis and alternative anticarcinogenic mechanisms… cannabidiol has been shown to elicit pronounced proapoptotic or autophagic effects on different types of tumor cells

This study investigates the role of COX-2 and PPAR-γ in cannabidiol’s proapoptotic and tumor-regressive action. In lung cancer cell lines (A549, H460) and primary cells from a patient with lung cancer, cannabidiol elicited decreased viability associated with apoptosis… our data show a novel proapoptotic mechanism of cannabidiol involving initial upregulation of COX-2 and PPAR-γ…

Collectively, our data strengthen the notion that activation of PPAR-γ may present a promising target for lung cancer therapy.

In addition and to the best of our knowledge, this is the first report to provide an inhibitor-proven tumor-regressive mechanism of cannabidiolin vivo as well as a proapoptotic mechanism confirmed by use of primary lung tumor cells.

Against this background and considering recent findings supporting a profound antimetastatic action of cannabidiol, this cannabinoid may represent a promising anticancer drug.”
