The rising prevalence of Parkinson’s disease (PD) globally presents a significant public health challenge for national healthcare systems, particularly in low-to-middle income countries, such as Thailand, which may have insufficient resources to meet these escalating needs. There are also many undiagnosed cases early-stage PD, period when therapeutic interventions would the most value and least cost. traditional “passive” approach, whereby clinicians wait patients with symptomatic PD seek treatment, is inadequate. Proactive, early identification will allow timely interventions, digital technologies can be scaled up diagnosis cases. risk survey (TCTR20231025005) aims evaluate population screening platform identify Thai population.

Abstract Aging is accompanied by the decline of organismal functions and a series prominent hallmarks, including genetic epigenetic alterations. These aging-associated changes include DNA methylation, histone modification, chromatin remodeling, non-coding RNA (ncRNA) regulation, all which participate in regulation aging process, hence contribute to aging-related diseases. Therefore, understanding mechanisms will provide new avenues develop strategies delay aging. Indeed, interventions based on manipulating have led alleviation or extension lifespan animal models. Small molecule-based therapies reprogramming that enable rejuvenation been developed for ameliorating reversing conditions. In addition, adopting health-promoting activities, such as caloric restriction, exercise, calibrating circadian rhythm, has demonstrated Furthermore, various clinical trials intervention are ongoing, providing more evidence safety efficacy these therapies. Here, we review recent work outline advances age-associated A better critical roles epigenetics process lead prevention human therapy

Aging is a complex biological process accompanied by progressive decline in the physical function of organism and an increased risk age-related chronic diseases such as cardiovascular diseases, cancer, neurodegenerative diseases. Studies have established that there exist nine hallmarks aging process, including (i) telomere shortening, (ii) genomic instability, (iii) epigenetic modifications, (iv) mitochondrial dysfunction, (v) loss proteostasis, (vi) dysregulated nutrient sensing, (vii) stem cell exhaustion, (viii) cellular senescence, (ix) altered communication. All these alterations been linked to sustained systemic inflammation, mechanisms contribute timing not clearly determined yet. Nevertheless, dysfunction one most important contributing process. Mitochondria primary endogenous source reactive oxygen species (ROS). During ATP production elevated ROS together with antioxidant defense. Elevated levels can cause oxidative stress severe damage cell, organelle membranes, DNA, lipids, proteins. This contributes phenotype. In this review, we summarize recent advances emphasis on production.

Several biomarkers of healthy aging have been proposed in recent years, including the epigenetic clocks, based on DNA methylation (DNAm) measures, which are getting increasingly accurate predicting individual biological age. The recently developed "next-generation clock" DNAmGrimAge outperforms "first-generation clocks" longevity and onset many age-related pathological conditions diseases. Additionally, total number stochastic mutations (SEMs), also known as mutation load (EML), has a complementary DNAm-based biomarker aging. A fundamental property epigenetic, particular DNAm modifications, is potential reversibility effect, raising questions about possible slowdown by modifying one's lifestyle. Here, we investigated whether improved dietary habits increased physical activity favorable effects postmenopausal women. study sample consists 219 women from "Diet, Physical Activity, Mammography" (DAMA) study: 24-month randomized factorial intervention trial with measured twice, at baseline end trial. Women who participated had significant slowing clock, whereas increasing led to reduction SEMs crucial cancer-related pathways. Our provides strong evidence causal association between lifestyle modification down biomarkers. This elucidates relationship aging-related mechanisms.

Abstract The diversity of cell types is a challenge for quantifying aging and its reversal. Here we develop ‘aging clocks’ based on single-cell transcriptomics to characterize cell-type-specific rejuvenation. We generated transcriptomes from the subventricular zone neurogenic region 28 mice, tiling ages young old. trained single-cell-based regression models predict chronological age biological (neural stem proliferation capacity). These clocks are generalizable independent cohorts other regions brains, species. To determine if these could quantify transcriptomic rejuvenation, datasets two interventions—heterochronic parabiosis exercise. Aging revealed that heterochronic exercise reverse in regions, but different ways. This study represents first development high-resolution data demonstrates their application

Abstract Several age predictors based on DNA methylation, dubbed epigenetic clocks, have been created in recent years, with the vast majority regularized linear regression. This study explores improvement performance and interpretation of clocks using deep learning. First, we gathered 142 publicly available data sets from several human tissues to develop AltumAge, a neural network framework that is highly accurate precise predictor. Compared ElasticNet, AltumAge performs better for within-data set cross-data prediction, being particularly more generalizable older ages new tissue types. We then used learning methods learn which methylation sites contributed final model predictions. observe while most important CpG are linearly related age, some highly-interacting can influence relevance such relationships. Using chromatin annotations, show highest contribution predictions were gene regulatory regions genome, including proximity CTCF binding sites. also found age-related KEGG pathways genes containing these Lastly, performed downstream analyses explore its applicability compare acceleration Horvath’s 2013 model. our approach predicts higher tumors, cells exhibit changes vitro, as immune mitochondrial dysfunction, samples patients multiple sclerosis, type 2 diabetes, HIV, among other conditions. Altogether, provides significant flexibility compared current both interpretability.
