Emerging evidence indicates that mitochondria, the essential energy powerhouse in cells, can be pharmacologically targeted. Aging dramatically impacts mitochondrial efficacy and plasticity, and to sustain mitochondrial biogenesis is the main objective of anti-aging medicine. Mitochondrial dysfunction at an ultrastructural level can be evidenced by the observation of abnormal cristae at the cellular level, characterized by altered size, number, and sub-cellular localization, as well as by reduced turnover and dynamics. These changes are associated with the disrupted function of the electron transport chain, showing lower electronic capacity, reduced membrane potential, increased production of superoxide, and reduced capacity to couple electronic flux to ATP synthesis. Neurons, skeletal and cardiac myocytes, and hepatocytes are among the most affected cell types due to their reliance on mitochondrial ATP output. Noted bioenergetic alterations—characteristics of aging— are also shared by cancer cells and have been suggested to have an impact on the control of cell death pathways, autophagy, and proteostasis. Recently, mitophagy has become a focus of attention in aging, metabolic diseases, and cancer. This is a selective mitochondrial clearing mechanism dependent on lysosomes, which has been shown to be defective or functionally altered, leading to the accumulation of dysfunctional mitochondria in the cell. Thus, targeting the mitochondria and restoring proper mitochondrial homeostasis are fundamental to treating disorders in which mitochondrial dysfunction has been shown to be a key driver of the disease. Novel developments have boosted our capacity to analyze mitochondria by evaluating cellular and circulating mtDNA—free and associated with regulatory factors. Therefore, the evaluation of epigenetic cues and mitochondrial medicine are challenging topics for future diagnostic and therapeutic developments. We believe that now is the time to support the exchange of ideas and the latest results on mitochondrial biology and medicine and have therefore decided to propose this Special Issue for interested clinical, academic, or industrial researchers all over the world. Original articles, comprehensive reviews, or perspective articles are welcome.
Topics of interest include, but are not limited to, the following:
- Mitochondria in aging;
- Mitochondria in exercise;
- Mitochondria in cancer,
- Mitochondria in neurodegeneration;
- Mitochondria in metabolic diseases;
- Mitochondrial mtDNA regulation;
- Mitochondrial oxidative pathways;
- Hypoxia regulation;
- Antioxidants and nutraceutical drugs.

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 papers will be 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.
