Scoping Review and Meta-Analysis Suggests that Cannabis Use May Reduce Cancer Risk in the United State, Thomas M. Clark, 2021

Scoping Review and Meta-Analysis Suggests that Cannabis Use May Reduce Cancer Risk in the United States Thomas M. Clark Cannabis and Cannabinoid Research, 2021, Volume 6, Number 5, 413-434. Doi : 10.1089/can.2019.0095   Abstract Introduction:Cannabis smoke contains carcinogens similar to tobacco, in addition to compounds with antitumor activity. Cannabis use reduces the risk of obesity and cannabinoids inhibit chronic inflammation, known causes of cancer. The net effect of Cannabis use on cancer risk is not known. Objective: To examine the association between Cannabis use and cancer risk in the United States. Methods: Identify and analyze published data on cancer risk in Cannabis users. Results: A total of 55 data [...]

New Insights on Hemp Oil Enriched in Cannabidiol: Decarboxylation, Antioxidant Properties and In Vitro Anticancer Effect, Anca Roxana Petrovici et al., 2021

New Insights on Hemp Oil Enriched in Cannabidiol: Decarboxylation, Antioxidant Properties and In Vitro Anticancer Effect Anca Roxana Petrovici, Natalia Simionescu, Andreea Isabela Sandu, Vasile Paraschiv, Mihaela Silion and Mariana Pinteala Antioxidants, 2021, 10, 738. doi : 10.3390/antiox10050738   Abstract : This study aimed to obtain and characterize extracted hemp oil enriched in cannabidiol (CBD) by decarboxylation of cannabidiolic acid (CBDA) and to give new insights into its antioxidant and anticancer effects. Optimization of CBDA decarboxylation in hemp oil was performed, and CBD and CBDA contents and purities were determined by flash chromatography, 1H- and 13C-NMR. The antioxidant properties of CBD-enriched oil were investigated by Fe2+ [...]

Cytotoxic Effects of Cannabinoids on Human HT-29 Colorectal Adenocarcinoma Cells: Different Mechanisms of THC, CBD, and CB83, Daniela Cerretani et al., 2020

Cytotoxic Effects of Cannabinoids on Human HT-29 Colorectal Adenocarcinoma Cells : Different Mechanisms of THC, CBD, and CB83 Daniela Cerretani, Giulia Collodel, Antonella Brizzi, Anna Ida Fiaschi, Andrea Menchiari, Elena Moretti, Laura Moltoni, Lucia Micheli International Journal of Molecular Sciences, 2020, 21, 5533 Doi : 10.3390/ijms21155533   Abstract In this study, we investigated the effects of exposition to IC50 dose for 24 h of a new synthetic cannabinoid (CB83) and of phytocannabinoids Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD) on HT-29 colorectal carcinoma cells. Cell viability and proliferative activity evaluated using the MTT, lactate dehydrogenase (LDH), and CyQUANT assays showed that cell viability was significantly affected when CB83, THC, and CBD [...]

Cannabidiol (CBD) Is a Novel Inhibitor for Exosome and Microvesicle (EMV) Release in Cancer, Uchini S. Kosgodage et al., 2018

Cannabidiol (CBD) Is a Novel Inhibitor for Exosome and Microvesicle (EMV) Release in Cancer Uchini S. Kosgodage, Rhys Mould, Aine B. Henley, Alistair V. Nunn, Geoffrey W. Guy, E. L. Thomas, Jameel M. Inal, Jimmy D. Bell and Sigrun Lange Frontiers in Pharmacology, 2018, Volume 9, Article 889 doi : 10.3389/fphar.2018.00889   Exosomes and microvesicles (EMV) are lipid bilayer-enclosed structures, released by cells and involved in intercellular communication through transfer of proteins and genetic material. EMV release is also associated with various pathologies, including cancer, where increased EMV release is amongst other associated with chemo-resistance and active transfer of pro-oncogenic factors. Recent studies show that [...]

Cancer, Cannabis, and the Search for Relief, Marcin Chwistek, 2019

Cancer, Cannabis, and the Search for Relief Marcin Chwistek JNCCN—Journal of the National Comprehensive Cancer Network, 2019, Volume 17, Issue 9, 1142-1144. doi : 10.6004/jnccn.2019.7347   “How about medical marijuana?” is a common and often challenging question in oncology clinics today. It is easy to see why. Answering the question is fraught with clinical, legal, and administrative uncertainties. We all want to give patients the best advice, but not much about medical cannabis seems straightforward today. Whatever answer we provide can feel unsatisfactory to patients or ourselves. Answering clinical questions through high-quality research will take many years. And significant political power will be needed to [...]

Report colloque UFCM – I Care, 2020

Cette année, nous avions prévu que le 9e colloque international se déroulerait en juin, chez nous, à Strasbourg et qu’il aborderait la thématique de la recherche sur les cannabinoïdes et les cancers. Aux vues des circonstances de ce début d’année 2020, nous avons pris la décision de reporter cet évènement à une date encore inconnue. Nous allons faire au mieux pour maintenir notre programme. Vous trouverez de plus amples détails dans le communiqué ci-dessous.

CBD Reverts the Mesenchymal Invasive Phenotype of Breast Cancer Cells Induced by the Inflammatory Cytokine IL-1, Lázaro García-Morales et al., 2020

CBD Reverts the Mesenchymal Invasive Phenotype of Breast Cancer Cells Induced by the Inflammatory Cytokine IL-1 Lázaro García-Morales, Aída M Castillo, José Tapia Ramírez, Horacio Zamudio-Meza, Ma del Carmen Domínguez-Robles and Isaura Meza International Journal of Molecular Science, 2020, 21, 2429 doi : 10.3390/ijms21072429   Abstract : Cannabidiol (CBD) has been used to treat a variety of cancers and inflammatory conditions with controversial results. In previous work, we have shown that breast cancer MCF-7 cells, selected by their response to inflammatory IL-1 cytokine, acquire a malignant phenotype (6D cells) through an epithelial mesenchymal transition (EMT).We evaluated CBD as a potential inhibitor of this transition and inducer of [...]

Cannabinoids : the lows and the highs of chemotherapy-induced nausea and vomiting, Toni Leigh Mortimer et al., 2019

Cannabinoids : the lows and the highs of chemotherapy-induced nausea and vomiting Toni Leigh Mortimer, Tom Mabin & Anna-Mart Engelbrecht Future Oncology, 2019 Doi : 10.2217/fon-2018-0530   Despite remaining one of the most widely abused drugs worldwide, Cannabis sativa exhibits remarkable medicinal properties. The phytocannabinoids, cannabidiol and -9-tetrahydrocannabinol, reduce nausea and vomiting, particularly during chemotherapy. This is attributed to their ability to reduce the release of serotonin from enterochromaffin cells in the small intestine, which would otherwise orchestrate the vomiting reflex. Although there are many preclinical and clinical studies on the effects of -9- tetrahydrocannabinol during nausea and vomiting, little is known about the role [...]

Impact of co-administration of oxycodone and smoked cannabis on analgesia and abuse liability, Ziva D. Cooper et al., 2018

Impact of co-administration of oxycodone and smoked cannabis on analgesia and abuse liability Ziva D. Cooper, Gillinder Bedi, Divya Ramesh, Rebecca Balter, Sandra D. Comer and Margaret Haney Neuropsychopharmacology, 2018, 0, 1–10 Doi : 10.1038/s41386-018-0011-2   Cannabinoids combined with opioids produce synergistic antinociceptive effects, decreasing the lowest effective antinociceptive opioid dose (i.e., opioid-sparing effects) in laboratory animals. Although pain patients report greater analgesia when cannabis is used with opioids, no placebo-controlled studies have assessed the direct effects of opioids combined with cannabis in humans or the impact of the combination on abuse liability. This double-blind, placebo-controlled, within-subject study determined if cannabis enhances the analgesic effects [...]

Down-Regulation of Cannabinoid Type 1 (CB1) Receptor and its Downstream Signaling Pathways in Metastatic Colorectal Cancer, Valeria Tutino et al., 2019

Down-Regulation of Cannabinoid Type 1 (CB1) Receptor and its Downstream Signaling Pathways in Metastatic Colorectal Cancer Valeria Tutino, Maria Gabriella Caruso, Valentina De Nunzio, Dionigi Lorusso, Nicola Veronese, Isabella Gigante, Maria Notarnicola and Gianluigi Giannelli Cancers, 2019, 11, 708, 1-14. doi :10.3390/cancers11050708   Abstract : Changes in the regulation of endocannabinoid production, together with an altered expression of their receptors are hallmarks of cancer, including colorectal cancer (CRC). Although several studies have been conducted to understand the biological role of the CB1 receptor in cancer, little is known about its involvement in the metastatic process of CRC. The aim of this study was to investigate the [...]
