Abstract Current research on human aging has largely been guided by the milestone paper “hallmarks of aging,” which were first proposed in seminal 2013 Lopez‐Otin et al. Most studies have focused one hallmark at a time, asking whether underlying molecular perturbations are sufficient to drive process and its associated phenotypes. More recently, researchers begun investigate phenotypes driven concurrent pathways linked not but multiple hallmarks they present different patterns organs systems over time. Indeed, preliminary results suggest that more complex interactions between must be considered addressed, if we develop interventions successfully promote healthy and/or delay aging‐associated dysfunction diseases. Here, summarize some latest work views interplay aging, with specific focus mitochondrial dysfunction. this represents significant example crosstalk effects an intervention targeted may others. A better knowledge these interconnections, their cause‐effect relationships, spatial temporal sequence, will very beneficial for whole field identification effective promoting old age.

Multi-omics usually refers to the crossover application of multiple high-throughput screening technologies represented by genomics, transcriptomics, single-cell proteomics and metabolomics, spatial so on, which play a great role in promoting study human diseases. Most current reviews focus on describing development multi-omics technologies, data integration, particular disease; however, few them provide comprehensive systematic introduction multi-omics. This review outlines existing technical categories multi-omics, cautions for experimental design, focuses integrated analysis methods especially approach machine learning deep integration corresponding tools, medical researches (e.g., cancer, neurodegenerative diseases, aging, drug target discovery) as well open-source tools databases, finally, discusses challenges future directions precision medicine.

The world has witnessed a steady rise in both non-infectious and infectious chronic diseases, prompting cross-disciplinary approach to understand treating disease. Current medical care focuses on people after they become patients rather than preventing illness, leading high costs late-stage diseases. Additionally, "one-size-fits all" health does not take into account individual differences genetics, environment, or lifestyle factors, decreasing the number of benefiting from interventions. Rapid advances omics technologies progress computational capabilities have led development multi-omics deep phenotyping, which profiles interaction multiple levels biology over time empowers precision approaches. This review highlights current emerging modalities for discusses applications following areas: genetic variation, cardio-metabolic cancer, organ transplantation, pregnancy, longevity/aging. We will briefly discuss potential approaches disentangling host-microbe host-environmental interactions. touch areas electronic record clinical imaging integration with muti-omics health. Finally, we challenges implementation its future prospects.

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

Mechanisms thought to contribute aging summarized under term "hallmarks aging" include loss proteostasis, mitochondrial dysfunction, altered nutrient sensing, telomere attrition, genomic instability, cellular senescence, stem cell exhaustion, epigenetic alterations intercellular communication. We here examine key claims about aging". Our analysis reveals important weaknesses that preclude strong definitive conclusions concerning possible role these in shaping organismal rate.

The composition of the human gut microbiome has been observed to change over course an individual's life. From birth, it is shaped by mode delivery, diet, environmental exposures, geographic location, exposures medications, and aging itself. Here, we present a narrative review across lifespan with focus on its impacts age-related diseases in humans. We will describe how shaped, features that have associated at different phases life this can adversely affect healthy aging. Across lifespan, especially old age, diverse includes organisms suspected produce anti-inflammatory metabolites such as short-chain fatty acids, reported be These findings remarkably consistent regions world suggesting they could universal all cultures genetic backgrounds. Exactly these biologic processes thus promoting crucial targeting for interventions support health longevity.
