Special Issue Information
Dear Colleagues,
While aging is unavoidable, lifespans differ even between closely related species. This suggests that minor genetic variations may have a significant impact on survival. The past decades of basic research on longevity identified genes and several mechanisms involved in the aging process. The free radical theory and other simple mechanisms of aging have thus been overridden by a more complex scenario where evolutionarily conserved genes and pathways affect longevity through specific “aging programs”. Although subtle differences between species exist, the key players involved in age progression are DNA repair, heat shock proteins, insulin/IGF1/TOR, SIRT family genes, and long non-coding RNAs. However, despite the inherited genetic factors, the modulation of these pathways by external stimuli is already possible and appears to be a more feasible strategy to counteract the derangement of physiological function driven by the aging process. Nutriepigenome and nutrient cellular and metabolic responses are now areas of interest that promise to uncover the mechanisms of lifespan.

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. Genes 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.
