Aging is a complex biological process accompanied by progressive decline in the physical function of organism and an increased risk age-related chronic diseases such as cardiovascular diseases, cancer, neurodegenerative diseases. Studies have established that there exist nine hallmarks aging process, including (i) telomere shortening, (ii) genomic instability, (iii) epigenetic modifications, (iv) mitochondrial dysfunction, (v) loss proteostasis, (vi) dysregulated nutrient sensing, (vii) stem cell exhaustion, (viii) cellular senescence, (ix) altered communication. All these alterations been linked to sustained systemic inflammation, mechanisms contribute timing not clearly determined yet. Nevertheless, dysfunction one most important contributing process. Mitochondria primary endogenous source reactive oxygen species (ROS). During ATP production elevated ROS together with antioxidant defense. Elevated levels can cause oxidative stress severe damage cell, organelle membranes, DNA, lipids, proteins. This contributes phenotype. In this review, we summarize recent advances emphasis on production.

Paleoproteomics, the study of ancient proteins, is a rapidly growing field at intersection molecular biology, paleontology, archaeology, paleoecology, and history. Paleoproteomics research leverages longevity diversity proteins to explore fundamental questions about past. While its origins predate characterization DNA, it was only with advent soft ionization mass spectrometry that became truly feasible. Technological gains over past 20 years have allowed increasing opportunities better understand preservation, degradation, recovery rich bioarchive found in archaeological paleontological records. Growing from handful studies 1990s on individual highly abundant paleoproteomics today an expanding diverse applications ranging taxonomic identification fragmented bones shells phylogenetic resolution extinct species exploration cuisines dental calculus pottery food crusts diseases. More broadly, these opened new doors understanding human–animal interactions, reconstruction environments environmental changes, expansion hominin fossil record through large scale screening nondiagnostic bone fragments, vertebrate record. Even advances, much proteomic still remains unexplored. Here we provide overview history field, summary major methods currently use, critical evaluation current challenges. We conclude by looking future, for which innovative solutions emerging technology will play important role enabling us access unexplored “dark” proteome, allowing fuller can interpretation

Aging can be seen as a physiological progression of biomolecular damage and the accumulation defective cellular components, which trigger amplify process, toward whole-body function weakening. Senescence initiates at level consists in an inability to maintain homeostasis, characterized by overexpression/aberrant expression inflammatory/immune/stress responses. is associated with significant modifications immune system cells, decline immunosurveillance, which, turn, leads chronic elevation inflammation/oxidative stress, increasing risk (co)morbidities. Albeit aging natural unavoidable it regulated some factors, like lifestyle diet. Nutrition, indeed, tackles mechanisms underlying molecular/cellular aging. Many micronutrients, i.e., vitamins elements, impact cell function. This review focuses on role exerted vitamin D geroprotection, based its ability shape cellular/intracellular processes drive response protection against infections age-related diseases. To this aim, main paths immunosenescence inflammaging are identified biotargets D.
