Mechanism of CB-R-mediated antitumor activity in breast cancer cells. By binding to CB1-R and CB2-R, CBs inhibit breast cancer cell proliferation through various mechanisms. They block cell cycle progression at the G1/S phase via CB1-R and at the G2/M phase via CB2-R activation. They induce breast cancer cell death via apoptosis, mediated by the activation of the transcription factor jun-D. In HER2-overexpressing breast cancer cells, they block cancer cell proliferation in culture and tumors by inhibiting Akt and ERK signaling. They also inhibit cell migration and angiogenesis via CB2-R. CB1-R activation inhibits the FAK/SRC/RhoA pathway leading to inhibition of cell migration. Cell migration blockade is also achieved by CB2-R activation through the inhibition of COX-2 and ERK signaling, which is important for triple-negative breast cancer. AC: adenylate cyclase; Akt: protein kinase B; CB-R: cannabinoid receptor; COX-2: cyclooxygenase-2; EMT: epithelial-mesenchymal transition; ERK: extracellular-signal-regulated kinase; FAK: focal adhesion kinase; GPR: G-protein coupled receptor; HER2: human epidermal growth factor receptor 2: MAPK: mitogen-activated protein kinase; mTOR: mammalian target of rapamycin; PI3K: Phosphoinositol-3-kinase; Raf: serine/threonine-protein kinase; RhoA: transforming protein RhoA; SRC: proto-oncogene tyrosine-protein kinase Src.

To target CB-R mediated pathways, compounds with different chemical structures were screened for CB-R receptor ligand activity. A number of these compounds were investigated in cell culture and animal tumor models to determine their antineoplastic effects. For relevant reviews, see references [37,38,39,40,41]. Their chemical structures are depicted in Figure 1 and their effects are discussed in the following chapters.

The current clinical trial is expected to recruit about 15 patients with low-grade lymphoma. If successful, Levy believes the treatment could be useful for many tumor types. He envisions a future in which clinicians inject the two agents into solid tumors in humans prior to surgical removal of the cancer as a way to prevent recurrence due to unidentified metastases or lingering cancer cells, or even to head off the development of future tumors that arise due to genetic mutations like BRCA1 and 2.

Meanwhile, Levy said: “All of these immunotherapy advances are changing medical practice. Our approach uses a one-time application of very small amounts of two agents to stimulate the immune cells only within the tumor itself. In the mice, we saw amazing, bodywide effects, including the elimination of tumors all over the animal.”

A mother-of-two claims she has cured her aggressive breast cancer by taking one drop of cannabis oil every day.Dee Mani, 44, refused chemotherapy when she was diagnosed with triple negative breast cancer – deemed the deadliest form – and instead opted to try CBD.

The cancer stem cells are the ones that produce the tumor. “It’s extraordinary,” continued Lisanti, “the cells just sit there as if in a state of suspended animation.” Importantly, DPI proved to be non-toxic for so-called “bulk” cancer cells, which are largely thought to be non-tumorigenic.This suggests that the compound might be successful where current chemotherapy fails. The team explains, “DPI treatment can be used to acutely confer a mitochondrial-deficient phenotype, which we show effectively depletes [cancer stem-like cells] from the heterogeneous cancer cell population.”“These findings have significant therapeutic implications for potently targeting [cancer stem-like cells] while minimizing toxic side effects,” they add.

Finally, Sagiv-Barfi explored the specificity of the T cells by transplanting two types of tumors into the mice. She transplanted the same lymphoma cancer cells in two locations, and she transplanted a colon cancer cell line in a third location. Treatment of one of the lymphoma sites caused the regression of both lymphoma tumors but did not affect the growth of the colon cancer cells.

The researchers believe the local application of very small amounts of the agents could serve as a rapid and relatively inexpensive cancer therapy that is unlikely to cause the adverse side effects often seen with bodywide immune stimulation.The study titled “Eradication of spontaneous malignancy by local immunotherapy” was published in Science Translational Medicine.

A team of British-based researchers set out to find a non-toxic therapeutic agent that targets the mitochondria of cancer cells.Mitochondria are energy-producing organelles found inside each cell. The compound recently found by the scientists can stop cancer stem-like cells from proliferating by interfering with their energy-creating process inside the mitochondria.

Ms Dani is still clear of cancer and continues to take the oil every night. She has written about her journey in a new book called ‘My Way’.Charities estimate around 15 per cent of all cases of breast cancer are triple negative – but death rates are proportionally higher. Ms Dani added: “Even though my cancer has gone I will take one capsule every night for the rest of my life.

“At first when I spoke to the doctor I agreed to everything I was told, I said I’d have one year worth of chemotherapy but then I did my research.“After finding out about cannabis oil I started to put one drop into a capsule every night and take it before bed.“Within four months I believe that I cured myself and then when I was given the all clear, I knew it was the cannabis that cured me.”
