Special Issue Information

Dear Colleagues,

This Special Issue aims to provide an overview and update on advances in the development of original hypotheses regarding biochemical reactions in tissues, organs and systems aimed at compensating for the effects and/or consequences of various damaging factors, elucidating different molecular and cellular mechanisms of physiological and pathological processes, as well as the action of effective drugs based on biomolecules. Furthermore, this Special Issue will highlight the epigenetic mechanisms of action, application and use of effective biomolecule-based agents to elucidate the molecular and cellular mechanisms of these compounds.

This Special Issue seeks to publish papers on the mechanisms directly related to molecular diagnosis and novel pathomechanisms regarding typical metabolic disorders, as well as molecular aspects of pathophysiological abnormalities in environmental and lifestyle diseases. The implementation of cell signaling mechanisms regulating physiological and pathogenetic processes under the influence of various damaging factors will also be the focus of this Special Issue. We would be very pleased if you would consider submitting an article on any topic related to this theme.

The editorial team is planning a fast publication process for this Special Issue and will handle all submissions in an expeditious manner. Your article will also be promoted by the journal to ensure that our community sees it and has every opportunity to read it.

I hope you will consider contributing to this Special Issue. Should you have any questions, please do not hesitate to get in touch with me. If you are not able to contribute at this time, I would be most grateful if you would share the details of this Special Issue with your peers or recommend someone from your network to us.

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. Biomolecules 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.

Anti-ageing biology and medicine programmes are a focus of genetics, molecular biology, immunology, endocrinology, nutrition, and therapy. This paper discusses metabolic therapies aimed at prolonging longevity and/or health. Individual components of these effects are postulated to be related to the energy supply by tricarboxylic acid (TCA) cycle intermediates and free radical production processes. This article presents several theories of ageing and clinical descriptions of the top markers of ageing, which define ageing in different categories; additionally, their interactions with age-related changes and diseases related to α-ketoglutarate (AKG) and succinate SC formation and metabolism in pathological states are explained. This review describes convincingly the differences in the mitochondrial characteristics of energy metabolism in animals, with different levels (high and low) of physiological reactivity of functional systems related to the state of different regulatory systems providing oxygen-dependent processes. Much attention is given to the crucial role of AKG and SC in the energy metabolism in cells related to amino acid synthesis, epigenetic regulation, cell stemness, and differentiation, as well as metabolism associated with the development of pathological conditions and, in particular, cancer cells. Another goal was to address the issue of ageing in terms of individual characteristics related to physiological reactivity. This review also demonstrated the role of the Krebs cycle as a key component of cellular energy and ageing, which is closely associated with the development of various age-related pathologies, such as cancer, type 2 diabetes, and cardiovascular or neurodegenerative diseases where the mTOR pathway plays a key role. This article provides postulates of postischaemic phenomena in an ageing organism and demonstrates the dependence of accelerated ageing and age-related pathology on the levels of AKG and SC in studies on different species (roundworm Caenorhabditis elegans, Drosophila, mice, and humans used as models). The findings suggest that this approach may also be useful to show that Krebs cycle metabolites may be involved in age-related abnormalities of the mitochondrial metabolism and may thus induce epigenetic reprogramming that contributes to the senile phenotype and degenerative diseases. The metabolism of these compounds is particularly important when considering ageing mechanisms connected with different levels of initial physiological reactivity and able to initiate individual programmed ageing, depending on the intensity of oxygen consumption, metabolic peculiarities, and behavioural reactions.
