Condition: Breast Cancer

Appraising the “entourage effect”: antitumor action of a pure cannabinoid ver- sus a botanical drug preparation in preclinical models of breast cancer

Abstract Breast cancer is the second leading cause of death among women. Although early diagnosis and development of new treatments have improved their prognosis, many patients present innate or acquired…

Antitumor Activity of Plant Cannabinoids with Emphasis on the Effect of Cannabidiol on Human Breast Carcinoma

D9 -Tetrahydrocannabinol (THC) exhibits antitumor effects on various cancer cell types, but its use in chemotherapy is limited by its psychotropic activity. We investigated the antitumor activities of other plant…

The endogenous cannabinoid anandamide inhibits human breast cancer cell proliferation

Anandamide was the first brain metabolite shown to act as a ligand of ‘‘central’’ CB1 cannabinoid receptors. Here we report that the endogenous cannabinoid potently and selectively inhibits the proliferation…

Targeting multiple cannabinoid anti-tumour pathways with a resorcinol derivative leads to inhibition of advanced stages of breast cancer

BACKGROUND AND PURPOSE The psychoactive cannabinoid Δ9 -tetrahydrocannabinol (THC) and the non-psychoactive cannabinoid cannabidiol (CBD) can both reduce cancer progression, each through distinct anti-tumour pathways. Our goal was to discover…

Synthetic cannabinoid receptor agonists inhibit tumor growth and metastasis of breast cancer

Cannabinoids have been reported to possess antitumorogenic activity. Not much is known, however, about the effects and mechanism of action of synthetic nonpsychotic cannabinoids on breast cancer growth and metastasis….

Pathways mediating the effects of cannabidiol on the reduction of breast cancer cell proliferation, invasion, and metastasis

Invasion and metastasis of aggressive breast cancer cells are the final and fatal steps during cancer progression. Clinically, there are still limited therapeutic interventions for aggressive and metastatic breast cancers…

Modulation of breast cancer cell viability by a cannabinoid receptor 2 agonist, JWH-015, is calcium dependent

Introduction: Cannabinoid compounds, both nonspecific as well as agonists selective for either cannabinoid receptor 1 (CB1 ) or cannabinoid receptor 2 (CB2 ), have been shown to modulate the tumor…

Cannabinoids: A new hope for breast cancer therapy?

Breast cancer is a very common disease that affects approximately 1 in 10 women at some point in their lives. Importantly, breast cancer cannot be considered a single disease as…

Cannabinoids reduce ErbB2-driven breast cancer progression through Akt inhibition

Background: ErbB2-positive breast cancer is characterized by highly aggressive phenotypes and reduced responsiveness to standard therapies. Although specific ErbB2-targeted therapies have been designed, only a small percentage of patients respond…

Cannabidiol Induces Programmed Cell Death in Breast Cancer Cells by Coordinating the Cross-talk between Apoptosis and Autophagy

Cannabidiol (CBD), a major nonpsychoactive constituent of cannabis, is considered an antineoplastic agent on the basis of its in vitro and in vivo activity against tumor cells. However, the exact…
