Special Issue Information

Dear Colleagues,

Ovarian cancer (OC) is the second most common and the most lethal gynecologic malignancy in the Western world. Late-stage ovarian cancer is incurable in the majority of cases. Most women have advanced disease, for which the standard of care remains as surgery and platinum-based cytotoxic chemotherapy. Additional treatments include targeted therapies that target specifically cancer-related processes necessary for tumor growth, division and spread. Nevertheless, in about 80% of cases, on average, disease relapse is expected after 24 months, and ultimately, multi-drug resistance develops, with very few women surviving five years after diagnosis. A large number of plant compounds have anti-cancer activity. Some plants (e.g., Cannabis sativa, Moringa oleifera, Camellia sinensis, Pao pereira, Xylocarpus granatum, Margaritaria discoidea, and Rauwolfia vomitoria) and molecules (e.g., phytocannabinoids, resveratrol, tetrandrine, naringin, and soy protein) were examined for their anti-OC activity in vivo, in vitro, and in clinical trials. This Special Issue aims to present studies that examine these molecules‘ anti-OC properties, chemical structures, mechanisms of action, structure–activity relationships, and their potential as chemotherapeutic drugs.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Molecules is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Ovarian cancer (OC) is the single most lethal gynecologic malignancy. Cannabis sativa is used to treat various medical conditions, and is cytotoxic to a variety of cancer types. We sought to examine the effectiveness of different combinations of cannabis compounds against OC. Cytotoxic activity was determined by XTT assay on HTB75 and HTB161 cell lines. Apoptosis was determined by flow cytometry. Gene expression was determined by quantitative PCR and protein localization by confocal microscopy. The two most active fractions, F5 and F7, from a high Δ9–tetrahydrocannabinol (THC) cannabis strain extract, and their standard mix (SM), showed cytotoxic activity against OC cells and induced cell apoptosis. The most effective phytocannabinoid combination was THC+cannabichromene (CBC)+cannabigerol (CBG). These fractions acted in synergy with niraparib, a PARP inhibitor, and were ~50-fold more cytotoxic to OC cells than to normal keratinocytes. The F7 and/or niraparib treatments altered Wnt pathway-related gene expression, epithelial–mesenchymal transition (EMT) phenotype and β-catenin cellular localization. The niraparib+F7 treatment was also effective on an OC patient’s cells. Given the fact that combinations of cannabis compounds and niraparib act in synergy and alter the Wnt signaling pathway, these phytocannabinoids should be examined as effective OC treatments in further pre-clinical studies and clinical trials.
