Special Issue Information
Dear Colleagues,
The imbalance between oxygen availability and demand at both tissue and cellular levels, termed “hypoxia”, triggers a rapid global reprogramming of gene expression to ensure survival and restore oxygen homeostasis. Additionally, since oxygen supply can be quickly restored, the hypoxia response also minimizes the risk of oxidative damage and activates cell death if oxygen levels cannot be restored.
Recent breakthroughs in research and technology have provided better insights into the metabolism of hypoxic cells and have highlighted the complexity of the tumor microenvironment (TME). Moreover, novel molecular mechanisms, including noncoding RNA-related regulatory networks, have introduced new regulatory circuits and therapeutic opportunities for hypoxic response. MicroRNAs, long noncoding RNAs, PiRNA, and other RNA molecules can significantly influence Hypoxia-Inducible Factor (HIF) activity and determine the fate of hypoxic cells. Furthermore, the development of synthetic analogs of these molecules and targeted delivery methods opens new therapeutic avenues that could significantly impact patients’ lives.
The ability to develop therapeutic strategies based on the molecular mechanisms underlying the hypoxic response is crucial for modern treatments of ischemic events, stroke, myocardial infarction, and various human tumors, as well as macular degeneration, glaucoma progression, and diabetic retinopathy. Although HIFs are recognized as master regulators of the hypoxic response, disease-specific therapeutic modulation of their activity remains challenging.
This Special Issue focuses on novel advances in our understanding of the biological and therapeutic roles of molecular mechanisms in regulating cell signaling and fate under hypoxia or ischemia.

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. Biomedicines 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 2600 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.
