Complete characterization of the genetic effects on gene expression is needed to elucidate tissue biology and the etiology of complex traits. In the present study, we analyzed 2,344 subcutaneous adipose tissue samples and identified 34,774 conditionally distinct expression quantitative trait locus (eQTL) signals at 18,476 genes. Over half of eQTL genes exhibited at least two eQTL signals.

Reliable predictors of long-term all-cause mortality are needed for middle-aged and older populations. Previous metabolomics mortality studies have limitations: a low number of participants and metabolites measured, measurements mainly using nuclear magnetic spectroscopy, and the use only of conventional statistical methods. To overcome these challenges, we applied liquid chromatography-tandem mass spectrometry and measured >1000 metabolites in the METSIM study including 10,197 men.

Article Synopsis
  • Research on abdominal obesity highlighted that the rs10494217 variant in the TBX15 gene is linked to adipocyte health and the heritability of obesity.
  • The frequency of this variant shows a geographical trend, decreasing from north to south, particularly evident in the Finnish population, suggesting an adaptive response to colder climates.
  • Individuals with the risk allele exhibit changes in gene expression related to thermogenesis and unhealthy fat cell growth, indicating the variant's possible role in promoting abdominal obesity.

The significant prevalence of mental health problems among children and adolescents is a major concern worldwide. The current study evaluates the impact of a year-long, school-based intervention, Flourishing Students, on adolescents' salivary cortisol levels, depressive symptoms, psychological well-being, and hope. Utilizing a cluster randomized design with intervention and control classes, 72 students engaged in 32 well-being lessons during academic year 2016-2017, whereas 68 students followed their standard curriculum.

Article Synopsis
  • The study explores the genetic factors influencing β-cell function (BCF) and their relationship to type 2 diabetes (T2D), expanding on previous genetic research using large-scale data.
  • By analyzing GWAS data from around 26,000 individuals, the researchers identified 55 unique genetic associations related to BCF traits derived from oral glucose tolerance tests.
  • The findings reveal key genes that regulate insulin secretion and illustrate how different genetic mechanisms can affect T2D risk, offering a deeper understanding of the complex biology behind the disease.
