Impact of senescent fibroblasts secretome in ovarian cancer dissemination

2 weeks 1 day ago
Aging is a significant risk factor in ovarian cancers, which remains one of the most lethal gynecological malignancies. Over 50 % of ovarian cancer cases occur in women aged 65 and older. During aging, senescent cells progressively accumulate in various tissues, contributing to structural and inflammatory changes in the tumor microenvironment. While recent studies have underscored the role of the senescent mesothelial cells in facilitating cancer cell dissemination, the contribution of senescent...

Stabilizing dual-phased perovskite towards high performance photovoltaics with enhanced batch stability and consistency

2 weeks 1 day ago
Fabricating high-performance perovskite solar cells (PSCs) with solution processing is conducive to low-cost commercial production, it is therefore rather critical to stabilize perovskite in both solution and solid phases. For this purpose, the speed-up ageing of perovskite solution in air was systematically studied and its severe spontaneous degradation was observed. To address this issue, we introduce 4-(trifluoromethyl) phenylhydrazine (TFPH) to modify the perovskite solution, which presents...

A centenarian single nucleotide polymorphism in collagen gene COL25A1 promotes longevity in C. elegans

2 weeks 1 day ago
Before human genome sequencing, a genome-wide study of sibling centenarian pairs identified a longevity-associated locus on chromosome 4. Here, we mapped the genes in this locus and identified a collagen gene, COL25A1. Introducing an SNP linked to longevity that changes a serine predicted to be phosphorylated to leucine in COL25A1, into col-99, the C. elegans ortholog, extended lifespan. These col-99(gk694263[S106L]) SNP-mutants exhibited enhanced innate immune-related transcriptional responses,...

Contribution of leukocyte telomere length to cardiovascular disease onset from genome-wide cross-trait analysis

2 weeks 1 day ago
Telomere shortening is a well-established marker of cellular aging and genomic instability. While the relationship between leukocyte telomere length and cardiovascular diseases has long been of interest, their genetic interplay remains incompletely understood. In this study, we observe substantial genetic overlap beyond genome-wide correlations and identify a potential causal relationship between leukocyte telomere length and coronary artery disease. Specifically, we discover 248 pleiotropic...
