Associations between common genetic variants and income provide insights about the socio-economic health gradient.

We conducted a genome-wide association study on income among individuals of European descent (N = 668,288) to investigate the relationship between socio-economic status and health disparities. We identified 162 genomic loci associated with a common genetic factor underlying various income measures, all with small effect sizes (the Income Factor). Our polygenic index captures 1-5% of income variance, with only one fourth due to direct genetic effects.

Zoledronate interrupts pre-osteoclast-induced angiogenesis via SDF-1/CXCR4 pathway.

Introduction: In this study, we tested the hypothesis that pre-osteoclast signaling is key in triggering post-traumatic angiogenesis in alveolar bone via the SDF-1/CXCR4 pathway. Interruption of osteoclast differentiation through zoledronate (Zol) disrupts the crosstalk between pre-osteoclasts and endothelial cells, hindering the initial angiogenic reaction following dental trauma. This disruption could therefore play a role in the pathogenesis of medication-related osteonecrosis of the jaw (MRONJ).

Lifetime brain atrophy estimated from a single MRI: measurement characteristics and genome-wide correlates.

A measure of lifetime brain atrophy (LBA) obtained from a single magnetic resonance imaging (MRI) scan could be an attractive candidate to boost statistical power in uncovering novel genetic signals and mechanisms of neurodegeneration. We analysed data from five young and old adult cohorts (MRi-Share, Human Connectome Project, UK Biobank, Generation Scotland Subsample, and Lothian Birth Cohort 1936 [LBC1936]) to test the validity and utility of LBA inferred from cross-sectional MRI data, i.e.

DREADD agonist compound 21 causes acute diuresis in wild-type mice.

The targeted activation or inhibition of specific cell populations using chemogenetics allows the precise dissection of cellular signaling and function. Designer receptors exclusively activated by designer drugs (DREADDs) is a chemogenetic platform initially developed by mutating human muscarinic receptors to be unresponsive to endogenous acetylcholine but exclusively activated by an "inert" designer drug. Compound 21 (C21) is a new and potent DREADD agonist; however, radioligand assays from a recent report indicated its ability to bind to endogenous G protein-coupled receptors (GPCRs), including muscarinic M1-3 receptors.

Targeting NADPH Oxidase as an Approach for Diabetic Bladder Dysfunction.

Diabetic bladder dysfunction (DBD) is the most prevalent complication of diabetes mellitus (DM), affecting >50% of all patients. Currently, no specific treatment is available for this condition. In the early stages of DBD, patients typically complain of frequent urination and often have difficulty sensing when their bladders are full.
