Special Issue Information

Dear Colleague,

This Special Issue aims to highlight the pleiotropic mechanism(s) underlying the processes of cancer initiation as well as progression and focus on the antitumor properties of agents derived from natural sources. Several small molecules isolated from plants, fruits, vegetables, spices, animal venoms/secretions, etc., have demonstrated significant efficacy against various malignancies. These agents can suppress different characteristic hallmarks of cancer cells and have been investigated in various preclinical as well as clinical studies. This Special Issue will highlight the potential role of such important natural agents in both cancer prevention and therapy.

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. Biomolecules 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 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.

Ferroptosis, a recently elucidated style of regulated cell death, has emerged as a significant area of investigation in cancer biology. Natural active compounds that have anti-cancer effects are promising candidates for cancer prevention. Iberverin, a natural compound derived from Brassica oleracea var. capitata, has been shown to exert anti-tumor activities in some cancers. However, its role in hepatocellular carcinoma (HCC) cells and the molecular mechanisms are still poorly understood. In this study, we proved that iberverin can induce intracellular reactive oxygen species (ROS) generation to inhibit cell proliferation and initiate ferroptotic cell death in HCC cells, which can be eradicated by the ferroptosis inhibitor ferrostatin-1 (Fer-1) or deferoxamine mesylate (DFO) and ROS scavenger (GSH or NAC). Mechanistically, iberverin treatment can simultaneously downregulate SLC7A11 mRNA level and degrade GPX4 through the ubiquitination pathway, leading to lipid peroxidation and ferroptotic cell death in HCC cells. Significantly, a low dose of iberverin can remarkably increase the sensitivity of HCC cells to ferroptosis induced by canonical ferroptosis inducers RSL3 and imidazole ketone erastin (IKE). This study uncovers a critical function of iberverin in preventing HCC through ferroptosis and provides a promising strategy for HCC treatment either via iberverin alone or in combination with canonical ferroptosis inducers in the future.

Breast cancer, the most prevalent malignant tumor among women globally, remains a critical area of focus for researchers striving to refine therapeutic approaches. As an important component of traditional Chinese medicine, Astragalus membranaceus (AM) has demonstrated potential for multifaceted impacts on breast cancer treatment through various mechanisms. To guide clinical practice and further explore the under-researched field of AM in breast cancer treatment, this paper mainly reviews the regulatory roles of AM-derived compounds and extracts on breast cancer cell proliferation, migration, invasion, and chemoresistance. Furthermore, this study delves into the synergistic effects observed when AM is co-administered with chemotherapeutic agents, including the enhancement of chemosensitivity, mitigation of toxic side effects, and reversal of drug resistance. This review indicates that AM holds promise not only as a therapy in breast cancer treatment but also paves the way for innovative integrated treatment approaches that combine the benefits of traditional medicine with modern pharmaceuticals. Nevertheless, future research endeavors are also urged to elucidate the in vivo pharmacological effects and underlying mechanisms of AM to inform more effective clinical treatment strategies.
