In conclusion, the connection between DNA damage and aging is emphasized by the secretion of senescence-associated proteins during cellular senescence, a phenotype which is activated by DNA damage and is common for both human and mice. Though much progress has been achieved, full understanding of these mechanisms has still a long way to go. XPO1 as a Novel Target for Therapies to Enhance Autophagy https://www.fightaging.org/archives/2018/05/xpo1-as-a-novel-target-for-therapies-to-enhance-autophagy/ Autophagy is the name given to a collection of cellular housekeeping processes that recycle damaged and un...

The objective here is a set of tests that (a) match up to the expected outcome based on human trials of mitochondrially targeted antioxidants, and (b) that anyone can run without the need to involve a physician, as that always adds significant time and expense. These tests are focused on the cardiovascular system, particularly measures influenced by vascular stiffness, and some consideration given to parameters relevant to oxidative stress and the development of atherosclerosis. A standard blood test, with inflammatory markers. An oxidized LDL cholesterol assessment. Resting heart rate and blood pressure. Heart r...

In conclusion, a debate exists on whether aging is a disease in itself. Some authors suggest that physiological aging (or senescence) is not really distinguishable from pathology, while others argue that aging is different from age-related diseases and other pathologies. It is interesting to stress that the answer to this question has important theoretical and practical consequences, taking into account that various strategies capable of setting back the aging clock are emerging. The most relevant consequence is that, if we agree that aging is equal to disease, all human beings have to be considered as patients to be treat...

This study demonstrates that small peptide domains derived from native protein amelogenin can be utilized to construct a mineral layer on damaged human enamel in vitro. Six groups were prepared to carry out remineralization on artificially created lesions on enamel: (1) no treatment, (2) Ca2+ and PO43- only, (3) 1100 ppm fluoride (F), (4) 20 000 ppm F, (5) 1100 ppm F and peptide, and (6) peptide alone. While the 1100 ppm F sample (indicative of common F content of toothpaste for homecare) did not deliver F to the thinly deposited mineral layer, high F test sample (indicative of clinical varnish treatment) formed mainly C...

This study aimed to investigate the exact function of RGC-32 in kidney diseases and explore the potential mechanism of RGC-32 in regulating cell cycle. RGC-32 knockout (RGC-32-/-) mice were generated from C57BL/6 embryonic stem cells. Differentially expressed proteins in the kidney were investigated with the isobaric tags for relative and absolute quantification (iTRAQ) technique. Gene ontology analyses (GO), Kyoto encyclopedia of genes and genomes (KEGG) pathway mapping analysis and functional network analysis were also performed. The expressions of Smc3, Smad 2-3, DNA-PK were further confirmed by qPCR. Results showed tha...

This study identifies the missing link between Lewy bodies and the type of damage that's been observed in neurons affected by Parkinson's. Parkinson's is a disorder of the mitochondria, and we discovered how Lewy bodies are releasing a partial break-down product that has a high tropism for the mitochondria and destroys their ability to produce energy." Lewy bodies were described a century ago, but it was not until 1997 that scientists discovered they were made of clumps of a misfolded protein called α-synuclein. When it's not misfolded, α-synuclein is believed to carry out functions related to the ...

In conclusion, most experimental data on immune changes with aging show a decline in many immune parameters when compared to young healthy subjects. The bulk of these changes is termed immunosenescence. Immunosenescence has been considered for some time as detrimental because it often leads to subclinical accumulation of pro-inflammatory factors and inflammaging. Together, immunosenescence and inflammaging are suggested to stand at the origin of most of the diseases of the elderly, such as infections, cancer, autoimmune disorders, and chronic inflammatory diseases. However, an increasing number of gerontologists have chall...

In conclusion, the present study demonstrated that TIGIT is a prominent negative immune regulator involved in immunosenescence. This novel finding is highly significant, as targeting TIGIT might be an effective strategy to improve the immune response and decrease age-related comorbidities.
