In this study, we found that TXNIP deficiency induces accelerated senescent phenotypes of mouse embryonic fibroblast (MEF) cells under high glucose condition and that the induction of cellular ROS or AKT activation is critical for cellular senescence. Our results also revealed that TXNIP inhibits AKT activity by a direct interaction, which is upregulated by high glucose and H2O2 treatment. In addition, TXNIP knockout mice exhibited an increase in glucose uptake and aging-associated phenotypes including a decrease in energy metabolism and induction of cellular senescence and aging-associated gene expression. We propose that...

I have posted a few notes about predictive diagnostic algorithms (see:An Algorithm Using Medical Record Data Predicts Risk for Parkinson's Disease;Should the Work Product of"Non-Explainable" Medical Algorithms Be Ignored) and disease risk scores (see:Genetic Risk Scores: Ready for Inclusion in the Medical Record?). Using AI techniques, researchers at Massachusetts General are developing a web site that will display a risk score for five common diseases after consumers upload their DNA to the site (see:Clues to Your Health Are Hidden at 6.6 Million Spots in Your DNA). The algorithm takes into account mill...

(Natural News) What if the drug meant to treat you actually gave you a different, just-as-bad disease? A report published in the medical journal Movement Disorders says this could be the case with statins, linking the use of the drugs to an increased risk of Parkinson’s disease. Statins are a class of drugs prescribed to...

DISCUSSION: Overall, the literature supports beneficial pleotropic effects of statin use in contrast-induced nephropathy, head injury, Alzheimer's and Parkinson's disease, nuclear cataract, prostate cancer, infection management, and spinal cord injury. Further investigation is warranted, and randomized clinical trials are needed to confirm the clinical utility suggested by the reported studies included in this meta-analysis.

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...

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...

Abstract By mole, cholesterol is the most abundant component of animal cell plasma membranes. Many membrane proteins have been shown to be functionally dependent on cholesterol, several of which have also been shown to bind cholesterol at well-defined locations on their membrane-facing surface. In this work, a combination of coarse-grained "Martini" and all-atom simulations are used to identify two, to our knowledge, new cholesterol-binding sites on the A2A adenosine receptor, a G-protein-coupled receptor that is a target for the treatment of Parkinson's disease. One of the sites is also observed to bind...

Conclusion: Our results showed that statin use is significantly associated with a lower risk of developing PD. Physicians should consider statin drug therapy, monitor its outcomes, and empower their patients to improve their knowledge, therapeutic outcomes, and quality of life. However, preventive measures and their associated mechanisms must be further assessed and explored.Neuroepidemiology 2017;49:142 –151
