Eicosapentaenoic acid attenuates renal lipotoxicity by restoring autophagic flux.

In conclusion, EPA counteracts lipotoxicity in the proximal tubule by alleviating autophagic numbness, making it potentially suitable as a novel treatment for obesity-related kidney diseases. PMID: 32546086 [PubMed - as supplied by publisher]

ConclusionGK extract treatment prominently reduced obesity and its associated metabolic complications, such as hyperlipidemia, hyperglycemia, and insulin resistance. Hence, GK extract can be used as a promising multi ‐target functional food that can improve metabolic syndrome‐related symptoms.This article is protected by copyright. All rights reserved

The degree to which Alzheimer's disease is a lifestyle condition is an interesting question. A good deal of research points to insulin resistance in the brain as important in the progression of Alzheimer's disease, to the point at which one group declared Alzheimer's to be a type 3 diabetes, a condition that should be thought of as primarily metabolic in origin. That idea gained enough traction that when a definitively new type of diabetes was discovered, it had to be named type 4 diabetes to avoid confusion. Insulin resistance and type 2 diabetes are a consequence of being overweight in the vast majority of patient...

In conclusion, it remains unclear if brain-specific regional and temporal changes occur in the expression of the different APP variants during AD progression. Since APP is also found in blood cells, assessing the changes in APP mRNA expression in peripheral blood cells from AD patients has been considering an alternative. However, again the quantification of APP mRNA in peripheral blood cells has generated controversial results. Brain APP protein has been analyzed in only a few studies, probably as it is difficult to interpret the complex pattern of APP variants and fragments. We previously characterized the soluabl...

Authors: Denisenko YK, Kytikova OY, Novgorodtseva TP, Antonyuk MV, Gvozdenko TA, Kantur TA Abstract Metabolic syndrome (MetS) has a worldwide tendency to increase and depends on many components, which explains the complexity of diagnosis, approaches to the prevention, and treatment of this pathology. Insulin resistance (IR) is the crucial cause of the MetS pathogenesis, which develops against the background of abdominal obesity. In light of recent evidence, it has been shown that lipids, especially fatty acids (FAs), are important signaling molecules that regulate the signaling pathways of insulin and inflammatory ...

I recently collaborated on a review paper covering the history of clinical work on upregulation of nicotinamide adenine dinucleotide (NAD) as an approach to therapy. This is of interest to the aging research community because NAD is important to mitochondrial function. NAD levels diminish with age, alongside a loss of mitochondrial function that is known to contribute to the onset and progression of many age-related conditions. Animal studies and a few clinical trials have indicated that increased NAD levels may improve, for example, cardiovascular function in older individuals, as a result of improved mitochondrial functi...

In this study, we sought to elucidate the role of VRK-1 in regulation of adult life span in C. elegans. We found that overexpression of VRK-1::GFP (green fluorescent protein), which was detected in the nuclei of cells in multiple somatic tissues, including the intestine, increased life span. Conversely, genetic inhibition of vrk-1 decreased life span. We further showed that vrk-1 was essential for the increased life span of mitochondrial respiratory mutants. We demonstrated that VRK-1 was responsible for increasing the level of active and phosphorylated form of AMPK, thus promoting longevity. A Fisetin Variant, C...

In this study, we examined the effects of oxytocin on the Aβ-induced impairment of synaptic plasticity in mice. To investigate the effect of oxytocin on synaptic plasticity, we prepared acute hippocampal slices for extracellular recording and assessed long-term potentiation (LTP) with perfusion of the Aβ active fragment (Aβ25-35) in the absence and presence of oxytocin. We found that oxytocin reversed the impairment of LTP induced by Aβ25-35 perfusion in the mouse hippocampus. These effects were blocked by pretreatment with the selective oxytocin receptor antagonist L-368,899. Furthermore, the tr...

In this study, we applied a well studied prediction model developed on data from five CpG sites, to increase the practicability of these tests. We have determined the biological age of the heart, specifically of the right atrium (RA) and left atrium (LA), and of peripheral blood leucocytes, by measuring the mitotic telomere length (TL) and the non-mitotic epigenetic age (DNAmAge). We found that DNAmAge, of both atrial tissues (RA and LA), was younger in respect to the chronological age (-12 years). Furthermore, no significant difference existed between RA and LA, suggesting that, although anatomically diverse and ex...

This study was the first to demonstrate a causal relationship between glial senescence and neurodegeneration. In this study, accumulations of senescent astrocytes and microglia were found in tau-associated neurodegenerative disease model mice. Elimination of these senescent cells via a genetic approach can reduce tau deposition and prevent the degeneration of cortical and hippocampal neurons. Most recently, it was shown that clearance of senescent oligodendrocyte progenitor cells in AD model mice with senolytic agents could lessen the Aβ plaque load, reduce neuroinflammation, and ameliorate cognitive deficits. ...
