Prevalence of FGFR2b Protein Overexpression in Advanced Gastric Cancers During Prescreening for the Phase III FORTITUDE-101 Trial.

Purpose: Fibroblast growth factor receptor 2 isoform IIIb (FGFR2b) protein overexpression is an emerging biomarker in gastric cancer and gastroesophageal junction cancer (GC). We assessed FGFR2b protein overexpression prevalence in nearly 3,800 tumor samples as part of the prescreening process for a global phase III study in patients with newly diagnosed advanced or metastatic GC.
Methods: As of June 28, 2024, 3,782 tumor samples from prescreened patients from 37 countries for the phase III FORTITUDE-101 trial (ClinicalTrials.
The ionic liquid-assisted sample preparation method pTRUST allows sensitive proteome characterization of a variety of bacterial endospores to aid in the search for protein biomarkers.

Bacterial endospores are ubiquitous and are responsible for various human infections. Recently, we reported that an ionic liquid (IL)-based sample preparation method (named pTRUST) facilitated highly efficient shotgun analysis of the Bacillus subtilis spore proteome in trace samples. In this study, we evaluated the efficiency and applicability of the pTRUST technology using three different spore preparations: one purified from the closely related subspecies B.

Objective: Osteoarthritis is a common joint disease caused by a variety of risk factors, and it has been found that many biochemical markers are abnormal in peripheral blood and urine of patients with OA. The aim of this study was to elucidate the causal relationship between biomarkers associated with these processes and OA using Mendelian randomization (MR) analysis.
Method: The inverse variance weighted (IVW) approach to MR was primarily used to explore causal associations between exposures and outcomes using publicly available genetic variants from large genome-wide association studies (GWAS).
Novel inflammatory markers in intracerebral hemorrhage: Results from Olink proteomics analysis.

Inflammation is a crucial factor in intracerebral hemorrhage (ICH) pathophysiology, but specific inflammatory biomarkers in ICH patients remain unclear. This study aimed to identify novel circulating inflammatory biomarkers for improved ICH prediction and diagnosis. We profiled expression levels of 92 cardiovascular disease related proteins in plasma from 26 matched ICH patients and controls using Olink technology.

Autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS) is a rare inherited condition described worldwide and characterized by a wide spectrum of heterogeneity in terms of genotype and phenotype. How sacsin loss leads to neurodegeneration is still unclear, and current knowledge indicates that sacsin is involved in multiple functional mechanisms. We hence hypothesized the existence of epigenetic factors, in particular alterations in methylation patterns, that could contribute to ARSACS pathogenesis and explain the pleiotropic effects of SACS further than pathogenic mutations.
