Pitfalls in performing genome-wide association studies on ratio traits.
HGG Adv
January 2025
Insitro, South San Francisco, CA, USA.
Genome-wide association studies (GWAS) are often performed on ratios composed of a numerator trait divided by a denominator trait. Examples include body mass index (BMI) and the waist-to-hip ratio, among many others. Explicitly or implicitly, the goal of forming the ratio is typically to adjust for an association between the numerator and denominator.

The process by which cells translate external mechanical cues into intracellular biochemical signals involves intricate mechanisms that remain unclear. In recent years, research into post-translational modifications (PTMs) has offered valuable insights into this field, spotlighting protein prenylation as a crucial mechanism in cellular mechanotransduction and various human diseases. Protein prenylation, which involves the covalent attachment of isoprenoid groups to specific substrate proteins, profoundly affects the functions of key mechanotransduction proteins such as Rho, Ras, and lamins.

Introduction: Torque Teno Virus (TTV), an "orphan" virus with unclear pathology, has been associated with various diseases and immune dysfunctions. This study investigates the link between TTV viremia and clinical markers in patients with severe to very severe COPD undergoing respiratory rehabilitation.
Methods: We analyzed 102 elderly COPD patients, stratified by TTV viremia levels (< or ≥ 4 log10 copies/mL).
Environmentally relevant concentrations of DBDPE (decabromodiphenyl ethane) induce intestinal toxicity in silkworms (Bombyx mori L.).

Decabromodiphenyl ethane (DBDPE) is one of the most extensively used novel brominated flame retardants, and it has been frequently detected in the global environment. Although organisms encounter various pollutants through the intestine, the toxicity effects of DBDPE exposure on the intestine and the potential mechanisms remain unclear. Here, by morphological observation, histopathology, high-throughput sequencing, and transcriptomics methods, we evaluated the effects of environmental (0.

Electronic address:
Functional cartilaginous tissues can potentially be engineered by bringing together numerous microtissues (µTs) and allowing them to fuse and re-organize into larger, structurally organized grafts. The maturation level of individual microtissues is known to influence their capacity to fuse, however its impact on the long-term development of the resulting tissue remains unclear. The first objective of this study was to investigate the influence of the maturation state of human bone-marrow mesenchymal stem/stromal cells (hBM-MSCSs) derived microtissues on their fusion capacity and the phenotype of the final engineered tissue.
