Special Issue Information
Dear Colleagues,
Selenoproteins, e.g., thioredoxin reductase (TXNRD) and glutathione peroxidase (GPX), play central roles in regulating cellular redox homeostasis. In recent years, the connections between the TXNRD and GPX and programmed cell deaths have been intensively established. The connections of these proteins to cell deaths are of pathological significance in maintaining phenotypes of various diseases and/or contributing to drug resistance. GPX4 is predominant for cellular ferroptosis defense by converting phospholipid hydroperoxides to phospholipid alcohol. Meanwhile, TXNRD is associated with the processes of reducing cystine sourced from system xc¯ to cysteine. Thus, an increasing number of natural or synthetic TXNRD or GPX4 inhibitors have been reported to suppress tumor growth by inducing ROS-dependent apoptosis or/and emerging ferroptosis. Considering these findings, targeting selenoprotein TXNRD or GPX4 has been recognized as a promising strategy for cancer therapy and/or sensitizing tumor cells to chemotherapeutic drugs.
The aim of this Special Issue is to collect the latest advances in targeting TXNRD of GPX4 in the cytosol and/or the mitochondria for the induction of programmed cell deaths (e.g., apoptosis, ferroptosis, necroptosis, autophagy, pyroptosis, etc.) and cancer treatment. Both review articles and original research articles are welcome. This Special Issue includes, but is not limited to, the following topics:
- Screening and discovery of novel drugs targeting TXNRD/GPX4;
- Design and synthesis of small molecules or metal complexes targeting TXNRD/GPX4;
- Pharmacological mechanism or signaling pathways of drugs targeting TXNRD/GPX4;
- Synergistic effects of TXNRD/GPX4 inhibitors with chemotherapeutic drugs;
- Overcoming tumor drug resistance by inhibiting TXNRD/GPX4;
- Metabolic reprogramming in cancer cells induced by targeting TXNRD/GPX4;
- Novel assays for screening effective TXNRD/GPX4 inhibitors;
- Novel probes for visualizing TXNRD/GPX4 functions.

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. Antioxidants 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). 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.
