Special Issue Information

Dear Colleagues,

Biology is calling for submissions to our Special Issue on “Mitochondrial Dysfunction and Aging”. The mitochondria not only work in energy production but also play important roles in reactive oxygen species (ROS and RNS) production, calcium handling, metabolism, cell signaling, etc. Mitochondria have been increasingly recognized as important players in the aging process. Mitochondrial dysfunction is one of the hallmarks of aging and aging-related diseases, including cardiovascular dysfunction, neurodegenerative diseases, skeletal muscle decline, kidney dysfunction, skin aging, immune dysfunction, and stem cell dysfunction. As individuals age, they become increasingly susceptible to various clinical complications. There is an urgent need to elucidate the mechanisms of mitochondrial dysfunction and seek mitochondrial-targeted treatments in aging. In this Special Issue, we welcome submissions of original research, reviews, and mini-reviews. Subtopics of interests include, but are not limited to, the following:

1) Mitochondrial DNA damage, reactive species (ROS and RNS) production, dynamics, and metabolism disorders in aging;
2) Mitochondrial dysfunction in various diseases in aging, including cardiovascular diseases, neurodegenerative diseases, Alzheimer’s diseases and related dementia, etc.;
3) Mitochondria and immune dysfunction in aging;
4) Mitochondrial dysfunction in stem cell aging;
5) Mitochondria and skeletal muscle cell dysfunction in aging;
6) Epigenetic regulation and potential targets in mitochondria in aging;
7) Other mitochondrial dysfunction in aging research.

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. Biology 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.

The protein associated with the silencing information regulator 2-associated enzyme1 (SIRT1) is a highly conserved nicotinamide adenine dinucleotide (NAD+)-dependent deacetylase and a key member of the sirtuin family. SIRT1 plays an essential role in various cellular physiological processes, primarily localized in the nucleus but also active in the cytoplasm and mitochondria. Recent studies have demonstrated its capacity to delay aging in multiple organs and tissues, although its underlying mechanisms remain incompletely understood. Additionally, SIRT1 exerts a significant influence on metabolic regulation and genetic processes. As the primary source of cellular energy, mitochondria are central to numerous biological functions. Mitochondrial dysfunction has been implicated in the onset and progression of various diseases and is increasingly recognized for its role in aging-related processes. This article investigates the interaction between SIRT1 and mitochondria in regulating reproductive system aging and elucidates their potential mechanisms of action, providing insights for clinical research into reproductive system aging.
