Special Issue Information

Dear Colleagues,

Triple-negative breast cancer (TNBC) is a subtype of breast cancer that lacks any targeted therapy, and despite current improvements in the treatment of breast cancer patients, fewer drugs have been approved and are available to these patients, especially those with metastatic TNBC. The first-line treatment options for these patients are chemotherapies which, despite their toxicity, are not very successful treatments, as often patients’ compliance with these treatments is low, and moreover, chemotherapies cannot overcome tumour resistance.

This Special Issue aims to integrate recent improvements in finding molecular targets and innovative approaches in the treatment of metastatic TNBC with an effort to expand the knowledge on a wide range of topics in this field. I would like to sincerely invite you to contribute to this Special Issue with your research articles and reviews, which can include, but are not limited to, the following topics: molecular targets, signalling pathways, miRs, gene expression and multigene predictors, role of epigenetics, stem cells, single or combination treatments, targeted treatments and novel targeted formulations, animal models, and clinical outcomes.

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. Pharmaceuticals is an international peer-reviewed open access monthly 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 2900 CHF (Swiss Francs).

Triple-negative breast cancer (TNBC) poses a therapeutic challenge due to its aggressive nature and lack of targeted therapies. Epigenetic modifications contribute to TNBC tumorigenesis and drug resistance, offering potential therapeutic targets. Recent advancements in three-dimensional (3D) organoid cultures, enabling precise drug screening, hold immense promise for identifying novel compounds targeting TNBC. In this study, we established two patient-derived TNBC organoids and implemented a high-throughput drug screening system using these organoids and two TNBC cell lines. Screening a library of 169 epigenetic compounds, we found that organoid-based systems offer remarkable precision in drug response assessment compared to cell-based models. The top 30 compounds showing the highest drug sensitivity in the initial screening were further assessed in a secondary screen. Four compounds, panobinostat, pacritinib, TAK-901, and JIB-04, targeting histone deacetylase, JAK/STAT, histone demethylases, and aurora kinase pathways, respectively, exhibited potent anti-tumor activity in TNBC organoids, surpassing the effect of paclitaxel. Our study highlights the potential of these novel epigenetic drugs as effective therapeutic agents for TNBC and demonstrates the valuable role of patient-derived organoids in advancing drug discovery.
