Topical application of the Wnt/β-catenin activator methyl vanillate increases hair count and hair mass index in women with androgenetic alopecia
2016
Activation of the WNT/β-catenin pathway has emerged as a potential therapeutic target in androgenetic alopecia (AGA). Methyl vanillate (MV) - a safe plant-derived ingredient - has been recently shown to activate the WNT/β-catenin signaling. Objectives Two distinct substudies were conducted. First, we designed a 6-month, uncontrolled, open-label clinical study to investigate whether topically applied MV may increase hair count and hair mass index (HMI) in female AGA. Second, we conducted a molecular study on the effect of MV on WNT10B mRNA expression in scalp biopsies of women with AGA. A total of 20 Caucasian women (age range: 25-57 years) with AGA (Sinclair grade 1-2) were included. The re…
Trace elements levels in centenarian ‘dodgers’
2016
Trace element bioavailability can play a role in several metabolic and physiological pathways known to be altered during the aging process. We aimed to explore the association of trace elements with increased lifespan by analyzing the circulating levels of seven trace elements (Cr, Cu, Fe, Mn, Mo, Se and Zn) in a cohort of healthy centenarians or ‘dodgers’ (≥100 years, free of major age-related diseases) in comparison with sex-matched younger elderly controls. Centenarians showed significant lower Cu (783.7 (76.7, 1608.9) vs 962.5 (676.3, 2064.4) μg/mL, P < 0.001), but higher Fe (1.3 (0.4, 4.7) vs 1.1 (0.5, 8.4) μg/mL, P = 0.003) and Se (85.7 (43.0, 256.7) vs 77.8 (24.3, 143.8) ng/mL, P = 0…
Inhibition of xanthine oxidase to prevent statin-induced myalgia and rhabdomiolysis
2015
Although statins remain the cornerstone of lipid-lowering therapy for reducing the burden of atherosclerotic vascular disease, their administration has been associated with muscle-related adverse effects, including myalgia and rhabdomyolysis. Such adverse events are probably due to reduced antioxidant defenses associated with fewer intermediate metabolites in the cholesterol synthesis pathway. We hypothesize that the concomitant inhibition of xanthine oxidase via coadministration of allopurinol with statins could diminish reactive oxygen species (ROS)-related muscle damage, which would have in turn have positive effects on both the incidence of muscle-related adverse events and cardiovascul…
Protective effect of trehalose-loaded liposomes against UVB-induced photodamage in human keratinocytes
2014
Trehalose, a naturally occurring non-reducing disaccharide, is known to act as a major protein stabilizer that can reduce ultraviolet B (UVB)-induced corneal damage when topically applied to the eye. However, due to the low skin permeability of trehalose, which makes the development of topical formulations difficult, its use as a skin photoprotective agent has been limited. Previous findings demonstrated that liposomes may significantly improve the intracellular delivery of trehalose. Therefore, the present study aimed to assess the protective effects of trehalose-loaded liposomes against UVB-induced photodamage using the immortalized human keratinocyte cell line, HaCaT. The effects were al…
Implications of obesity in exceptional longevity.
2016
Except for the world’s poorest regions, it is estimated that global obesity [body mass index (BMI) >30 kg/m 2 ] prevalence will reach 18% (men) and >21% (women) by 2025 (1). Recent nationally representative surveys in the US for the 2013–2014 period indicate age-adjusted obesity prevalence of 35.0% and 40.4% among adult men and women, respectively (2) and of 17.0% for children and adolescents aged 2–19 years (3).
Serum irisin levels, precocious myocardial infarction, and healthy exceptional longevity.
2014
Abstract Background Skeletal muscles produce irisin. Growing controversy exists on the association between this myokine and chronic disease risk. On the basis of the potential protective effects that irisin could exert on both vascular function and skeletal muscle mass, we hypothesized that an elevated level of this molecule may contribute to successful aging. Methods Serum irisin levels were measured using enzyme-linked immunosorbent assay in disease-free centenarians, young healthy controls, and patients with precocious acute myocardial infarction. Results We found the highest levels of serum irisin in disease-free centenarians (35.3 ± 5.5 ng/mL) compared with young healthy controls (20.7…
Guidelines for the use and interpretation of assays for monitoring autophagy (3rd edition)
2016
Seuls les 100 premiers auteurs dont les auteurs INRA ont été entrés dans la notice. La liste complète des auteurs et de leurs affiliations est accessible sur la publication.; International audience; In 2008 we published the first set of guidelines for standardizing research in autophagy. Since then, research on this topic has continued to accelerate, and many new scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Accordingly, it is important to update these guidelines for monitoring autophagy in different organisms. Various reviews have described the range of assays that have been used for this purpose. Nevertheless, there continues…
PTK2 rs7460 and rs7843014 polymorphisms and exceptional longevity: a functional replication study
2014
Focal adhesion is critical for cell survival. The focal adhesion kinase (FAK, or PTK2) is an important component of the human interactome and thus is a potential longevity-related protein. Here we studied the association between two PTK2 gene single-nucleotide polymorphisms (SNPs) (rs7843014, rs7460) and exceptional longevity (EL). In addition to gaining insight into their functionality by determining luciferase gene reporter activity, we studied the genotype/allele frequency of these two SNPs among three different cohorts: (1) Spanish centenarians (n=175, 100–111 years, 144 women) and healthy controls (n=355, 20–50 years, 284 women); (2) Italian centenarians (n=79, 100–104 years, 40 women)…
Elite athletes live longer than the general population: a meta-analysis
2014
OBJECTIVE: To perform a meta-analysis of cohort studies aimed at providing an accurate overview of mortality in elite athletes. PATIENTS AND METHODS: We reviewed English-language scientific articles available in Medline and Web of Science databases following the recommendations of the Meta-analyses Of Observational Studies in Epidemiology group. We searched for publications on longevity and professional or elite athletes (with no restriction on the starting date and up to March 31, 2014). RESULTS: Ten studies, including data from a total of 42,807 athletes (707 women), met all inclusion criteria. The all-cause pooled standard mortality ratio (SMR) was 0.67 (95% CI, 0.55-0.81; P<.001) with n…
Vitamin D, precocious acute myocardial infarction, and exceptional longevity
2015
Recent studies have reported low circulating levels of 25-hydroxyvitamin D (25(OH)D), the biologically active form of vitamin D, in patients with cardiovascular disease (CVD) [1], hypertension [2], carotid atherosclerosis [3], atrial fibrillation [4], and heart failure [5]. Moreover, vitamin D deficiency has been associated with all-cause mortality [6,7] and predicts adverse cardiac events in patients with established CVD [8] or after acute myocardial infarction (AMI) [9]. In turn, vitamin D supplementation improves the modulation of autonomic tone [10]. 4.638 JCR (2015) Q1, 24/124 Cardiac and cardiovascular systems UEM

Muscle-Related Polymorphisms (MSTN rs1805086 and ACTN3 rs1815739) Are Not Associated with Exceptional Longevity in Japanese Centenarians
2016
Myostatin (MSTN) and α-actinin-3 (ACTN3) genes are potentially associated with preservation of muscle mass and oxidative capacity, respectively. To explore the possible role of these genes in exceptional longevity (EL), the allele/genotype frequency distribution of two polymorphisms in MSTN (rs1805086, K153R) and ACTN3 (rs1815739, R577X) was studied in Japanese centenarians of both sexes (n = 742) and healthy controls (n = 814). The rs1805086 R-allele (theoretically associated with muscle mass preservation at the expense of oxidative capacity) was virtually absent in the two groups, where genotype distributions were virtually identical. Likewise, no differences in allele (p = 0.838 (women);…
