Abstract
Microplastics (MPs) are ubiquitous in aquatic and terrestrial ecosystem, increasingly becoming a serious concern of human health. Many studies have explored the biological effects of MPs on animal and plant life in recent years. However, information regarding the effects of MPs on aging and lifespan is completely lacking in vertebrate species to date. Here we first confirm the bioavailability of MPs by oral delivery in the annual fish N. guentheri. We then show for the first time that administration of MPs not only shortens the lifespan but also accelerates the development of age-related biomarkers in N. guentheri. We also demonstrate that administration of MPs induces oxidative stress, suppresses antioxidant enzymes, reduces digestive enzymes, and causes hepatic dysfunction. Therefore, we propose that administration of MPs reduces lifespan of N. guentheri via induction of both suppressed antioxidant system and digestive disturbance as well as hepatic damage. Our results also suggest that smaller MPs appear more toxic to digestion, metabolism and growth of animals.

Song L, Leng K, Xiao K, Zhang S. Administration of krill oil extends lifespan of fish Nothobranchius guentheri via enhancement of antioxidant system and suppression of NF-κB pathway. FISH PHYSIOLOGY AND BIOCHEMISTRY 2022; 48:1057-1073. [PMID: 35834112 DOI: 10.1007/s10695-022-01102-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/05/2022] [Accepted: 07/05/2022] [Indexed: 06/15/2023]
Abstract
Krill oil (KO) extracted from Antarctic krill (Euphausia superba) mainly comprises phospholipids and triglycerides. KO has been shown to prolong the median lifespan of the nematode Caenorhabditis elegans, but to shorten the lifespan of long-lived F1 mice; therefore, it remains controversial over the life-extending property of KO. In this study, we clearly demonstrated that dietary intake of KO extended both the mean and maximum lifespans of aged male Nothobranchius guentheri (p < 0.05), reduced the accumulation of lipofuscin (LF) (p < 0.05) in the gills and senescence-associated β-galactosidase (SA-β-Gal) (p < 0.05) in the caudal fins, and lowered the levels of protein oxidation (p < 0.05), lipid peroxidation (p < 0.01), and reactive oxygen species (ROS) (p < 0.01) in the muscles and livers, indicating that KO possesses rejuvenation and anti-aging activity. We also showed that KO enhanced the activities of antioxidant enzymes catalase (CAT) (p < 0.05), superoxide dismutase (SOD) (p < 0.05), and glutathione peroxidase (GPX) (p < 0.05) in aged male N. guentheri. In addition, KO administration effectively reversed histological lesions including inflammatory cell infiltration and structural collapse in the muscles and livers of aged N. guentheri and suppressed the nuclear factor kappa-B (NF-κB) signaling pathway (p < 0.05), a master regulator of inflammation. Altogether, our study indicates that KO has anti-aging and rejuvenation property. It also suggests that KO exerts its anti-aging and rejuvenation effects via enhancement of the antioxidant system and suppression of the NF-κB signaling pathway.

Abstract
Isthmin 1 (Ism1) has been shown to play roles in multiple biological processes including morphogenesis, hematopoiesis, antiviral immune response and suppression of tumor growth. However, it remains unknown if it plays any role in aging process. Here we showed for the first time that Ism1 was a new age-related biomarker, which decreased with age in fish, mice and humans. Interestingly, Ism1 was also useful to measure the "rejuvenated" age of fish Nothobranchius guentheri reversed by salidroside treatment and temperature reduction, providing additional evidence that Ism1 was an aging biomarker. In addition, we clearly showed that dietary intake of recombinant Ism1 had little effects on the body length and weight of aging N. guentheri, but it retarded the onset of age-related biomarkers and prolonged both the maximum and median lifespan of the fish. We also showed that Ism1 exerted its rejuvenation activity via the enhancement of antioxidant system. Collectively, our results indicate that Ism1 is not only is a novel biomarker of aging but also a potential rejuvenation factor capable of reversing aging of N. guentheri.

Abstract
In recent decades, the increase in human longevity has made it increasingly important to expand our knowledge on aging. To accomplish this, the use of animal models is essential, with the most common being mouse (phylogenetically similar to humans, and a model with a long life expectancy) and Caenorhabditis elegans (an invertebrate with a short life span, but quite removed from us in evolutionary terms). However, some sort of model is needed to bridge the differences between those mentioned above, achieving a balance between phylogenetic distance and life span. Fish of the genus Nothobranchius were suggested 10 years ago as a possible alternative for the study of the aging process. In the meantime, numerous studies have been conducted at different levels: behavioral (including the study of the rest-activity rhythm), populational, histochemical, biochemical and genetic, among others, with very positive results. This review compiles what we know about Nothobranchius to date, and examines its future prospects as a true alternative to the classic models for studies on aging.

Abstract
Genetic and pharmacological research on aging is hampered by the lifespan of available vertebrate models. We recently initiated studies on Nothobranchius furzeri, a species with a maximum life expectancy in captivity of just three months which represents the shortest documented captive lifespan for a vertebrate. Further research on N. furzeri has demonstrated that 1. Short lifespan is tied with explosive growth and accelerated sexual maturation. 2. Short lifespan is correlated with expression of age-related behavioral and histological changes. 3. Lifespan and expression of age-related markers can be modulated by water temperature. 4. Resveratrol, a drug characterized for its life-extending action in Caenorhabditis elegans and Drosophila, increases lifespan and retards expression of age-related markers. 5. Aging-related genes can be easily isolated by homology cloning. Finally, different populations or species of Nothobranchius show large-scale differences in captive lifespan. In the last three years, N. furzeri has moved from biological curiosity to a promising model system for drug validation. Furthermore, this species occupies a favorable position in the Teleost's "tree of life". It is very close to the Japanese Medaka, and close to the pufferfishes and stickleback and might represent a very useful model for comparative genomics of aging.

Abstract
Aging research in vertebrates is hampered by the lack of short-lived models. Annual fishes of the genus Nothobranchius live in East African seasonal ponds. Their life expectancy in the wild is limited by the duration of the wet season and their lifespan in captivity is also short. Nothobranchius are popular aquarium fishes and many different species are kept as captive strains, providing rich material for comparative studies. The present paper aims at reviving the interest in these fishes by reporting that: (1) Nothobranchius can be cultured, and their eggs stored dry at room temperature for months or years, offering inexpensive methods of embryo storage; (2) Nothobranchius show accelerated growth and expression of aging biomarkers at the level of histology and behaviour; (3) the species Nothobranchius furzeri has a maximum lifespan of only 3 months and offers the possibility to perform investigations thus far unthinkable in a vertebrate, such as drug screening with life-long pharmacological treatments and experimental evolution; (4) when the lifespan of different species is compared, a general correlation is found between wet season duration in their natural habitat and longevity in captivity; and (5) vertebrate aging-related genes, such as p66Shc and MTP, can be easily isolated in Nothobranchius by homology cloning. These fishes can become excellent models for aging studies. They can be employed to test the effects of experimental manipulation on aging at a pace comparable with that of Drosophila and to probe the effects of natural selection on the evolution of aging-related genes.

Abstract
Like the weather, many people talk about aging, but no one seems able to do anything about it. This implacability derives, at least in part, from our inability to provide a conceptual base from which analytic insight might derive. The emerging field of nonlinear thermodynamics presents a new view of the universe. It relates matter and energy in the framework of time. Entropy, "time's arrow," gives direction. Energy, rendered coherent through the metabolism of biology, acts to retard dissipation as entropy. For physicians, particularly those interested in geriatrics, this provides the challenge to understand how these forces are inscribed onto the human condition. The homeostatic controls which order our existence are energy dependent. As energies diminish, homeostasis as order deteriorates, aging proceeds and life is threatened. It seems to follow that if we are to diminish the entropic declines of aging our clinical strategies should emphasize actions which might retard the disruption of ordering processes. Homeostasis is at risk to the ravages of disease. This has been the standard business of medicine. But homeostasis is manifestly determined by the ordering effects of an energy flow. Either too little energy flow as disuse, or too much, as stress, lends further major burden to homeostatic controls. Every body system, at every level of organization, is beholden to this mandate. As our wisdom stretches to encompass the notion that aging and illness have other dimensions than just disease our view of ourselves will become more whole and in enlarging consonance with universal law.
