Visualizing the chronicle of multiple cell fates using a near-IR dual-RNA/DNA-targeting probe

1 week 3 days ago
Early detection and late-stage cell fate assessment are key factors to develop therapeutic strategies, although current methods cannot capture early responses or distinguish multiple injury states, especially in ultraviolet-visible (UV-vis)-sensitive cells. Here, we introduce a method to simultaneously detect variations in RNA and DNA under near-infrared photoexcitation. Using a pyrazinacene-based probe (TEG(8)-N14), we unexpectedly achieved discrimination of multiple cell states, including...

An optimized click chemistry method allows visualization of proliferating neuronal progenitors in the mouse brain

1 week 3 days ago
We establish a click reaction-based workflow (tissue clearing coupled with click-chemistry in 3D, C⁴-3D) to visualize 5-ethynyl-2'-deoxyuridine (EdU) in whole mouse brain tissue cleared by CUBIC, iDisco+, and PACT. C⁴-3D was compatible with immunostaining, nuclear staining, and a fluorescent reporter mouse. Machine learning-based identification of EdU-positive nuclear coordinates followed by normalization for the Allen Brain Atlas revealed that proliferating neuronal progenitors were enriched in...

Targeting VGLL4 maintains extracellular matrix homeostasis and mitigates osteoarthritis in a preclinical model

1 week 3 days ago
Extracellular matrix homeostasis is crucial for hyaline cartilage integrity, however, the mechanism of extracellular matrix homeostasis in hyaline cartilage is poorly understood. Single-cell sequencing shows that VGLL4 is highly expressed in chondrocytes but declines after injury/aging. VGLL4 deficiency impairs collagen/elastin formation, causes extracellular matrix disorganization and osteoarthritis in Col2-CreERT2; Vgll4^(fl/fl) mice, and is exacerbated by destabilization of the medial...

Tissue and cellular spatiotemporal dynamics in colon aging

1 week 3 days ago
Tissue structure and molecular circuitry in the colon can be profoundly impacted by systemic age-related effects but many of the underlying molecular cues remain unclear. Here, we build a cellular and spatial atlas of the colon across three anatomical regions and 11 age groups, encompassing ~1,500 mouse gut tissues profiled by spatial transcriptomics and ~400,000 single nucleus RNA-sequencing profiles. We develop a computational framework, cSplotch, which learns a hierarchical Bayesian model of...

Comparative evaluation of relative fat mass and body mass index in predicting cardiometabolic multimorbidity in older adults: results from the English Longitudinal Study of Ageing

1 week 3 days ago
Relative fat mass (RFM) is a more accurate measure of body fat percentage than body mass index (BMI). However, its association with cardiometabolic multimorbidity (CMM) and its predictive value have not been examined. This study evaluated and compared the associations and predictive utility of RFM and BMI for CMM. We analyzed data from 3,348 adults (mean age 64 years; 45.1% male) in the English Longitudinal Study of Ageing who were free of hypertension, coronary heart disease, diabetes, and...

Methylation patterns associated with TTV load in geriatric hospitalized patients: an exploratory functional analysis

1 week 3 days ago
Torque Teno Virus (TTV) is a widespread commensal virus within the human virome, characterized by a high prevalence in human population and an unclear pathogenic role. Over the past three decades, TTV has garnered increasing attention due to its ability to establish lifelong chronic viremia, which intriguingly fluctuates among individuals in relation to immune competence status, with a typical peak after an organ transplantation, followed by a plateau and a slow decrease. The regulatory...

The relationship between socio-economic and demographic factors, quality of life and depression in older women in institutional care in Poland - a cross-sectional study

1 week 3 days ago
CONCLUSION: The prevalence of depressive symptoms among older women in institutional care in south-western Poland is moderate. The intensity of these depressive symptoms lowers the overall quality of life of care centre residents, as well as their self-assessment of health, and affects their quality of life in the psychological, social, and environmental domains.
