Special Issue Information

Dear Colleagues,

Cancers represent one of the most common causes of death worldwide. Current drug anti-cancer treatment is multidirectional and involves both synthetic compounds and bioactive ones. Bioactive anti-cancer molecules are compounds derived from natural sources (e.g., plants, microorganisms, animals) and were discovered for the first time thousands of years ago. To date, at least 78 plant-derived compounds, also called phytochemicals, have been found to show anti-cancer activity. These include alkaloids, flavonoids, terpenes, isoflavones, and phenols. Some of these compounds have been successfully used in current treatment regimens and some are still under investigation for use in cancer cell lines. For example, vinca alkaloids like vincristine, vinorelbine, and vinblastine are plant-derived molecules and cell cycle inhibitors that have been used in the chemotherapeutic regimens of both solid and hematological malignancies for many years. The antiproliferative activity of bioactive molecules is also associated with their inhibition of certain intracellular signaling pathways that play a key role in development and maintenance of cancer cells. Moreover, natural molecules, due to their relatively low toxicity compared to synthetic compounds, are currently an attractive therapeutic target in cancer treatment.

This Special Issue of the International Journal of Molecular Sciences is dedicated to all research types, including both original and review articles, exploring new or already known plant-derived anti-cancer compounds with special attention paid to their mechanisms of action in cancer cells and their safety profile.

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.

Previously we discovered that among 15 DNA-binding plant secondary metabolites (PSMs) possessing anticancer activity, 11 compounds cause depletion of the chromatin-bound linker histones H1.2 and/or H1.4. Chromatin remodeling or multiH1 knocking-down is known to promote the upregulation of repetitive elements, ultimately triggering an interferon (IFN) response. Herein, using HeLa cells and applying fluorescent reporter assay with flow cytometry, immunofluorescence staining and quantitative RT-PCR, we studied effects of PSMs both evicting linker histones from chromatin and not influencing their location in nucleus. We found that (1) 8 PSMs, evicting linker histone H1.2 from chromatin, activated significantly the type I IFN signaling pathway and out of these compounds resveratrol, berberine, genistein, delphinidin, naringenin and curcumin also caused LINE1 expression. Fisetin and quercetin, which also induced linker histone H1.2 eviction from chromatin, significantly activated only type I IFN signaling, but not LINE1 expression; (2) curcumin, sanguinarine and kaempferol, causing significant depletion of the chromatin-bound linker histone H1.4 but not significantly influencing H1.2 presence in chromatin, activate type I IFN signaling less intensively without any changes in LINE1 expression; (3) four PSMs, which did not cause linker histone eviction, displayed neither IFN signaling activation nor enhancement of LINE1 expression. Thus, we have shown for the first time that chromatin destabilization observed by depletion of chromatin-bound linker histone H1.2 caused by anticancer DNA-binding PSMs is accompanied by enhancement of type I IFN signaling, and that LINE1 expression often impacts this activation.
