De Novo Design of Multivalent α/β‐Peptides Mimicking Transcription Factors Targeting the CBP KIX Domain

Chemistry – A European Journal, EarlyView.
A modular, de novo α/β‐peptide design strategy allows fine‐tuning of ligand properties, resulting in multivalent ligands that simultaneously target separate binding sites on the protein surface. ABSTRACT Protein‐protein interactions that regulate gene expression in the nucleus are increasingly recognized as potential therapeutic targets but present ...

Effect of Late Second to Early Third Trimester of Pregnancy on the Activity of Renal Organic Anion Transporters (OAT1 and OAT3): A Biomarker Study

Clinical Pharmacology &Therapeutics, EarlyView.
Pregnant individuals take drugs throughout pregnancy and many of these drugs (e.g., antivirals, antibiotics) are eliminated by renal organic anion transporters (OAT) 1 and OAT3. In vivo studies with OAT1/3 substrate drugs suggest that pregnancy increases renal OAT1/3 activities by 1.5‐ to 1.8‐fold.

Detection of the GH Analogue Redalsomatropin Alfa in Sports Drug Testing: Immunological Approaches and LC‐HRMS/MS

Drug Testing and Analysis, EarlyView.
After evaluating the compatibility of the GH analogue redalsomatropin alfa with approved doping control immunoassays for rhGH, it was implemented into the existing detection method for somatrogon employing affinity purification with GHR‐Fc‐conjugated magnetic beads, tryptic digestion, and LC‐HRMS/MS to allow for a specific and sensitive detection ...

Identification of Synthetic Urine by Analysis of Stable Carbon and Nitrogen Isotope Ratios and Comparison to Established GC‐MS/MS and LC‐MS/MS Analysis

Drug Testing and Analysis, EarlyView.
This study compared GC‐MS/MS, EA‐IRMS, and LC‐MS/MS for detecting synthetic and manipulated urine samples in doping control and forensic analysis. EA‐IRMS proved particularly effective for identifying mixtures of synthetic and authentic urine, providing a reliable complement to established authenticity testing methods.

The β integrin modulates serotonin sensitivity via NPxY motifs to regulate egg laying and mechanosensation behaviors in Caenorhabditis elegans

Developmental Dynamics, EarlyView.
Abstract Background Integrin is an αβ heterodimeric receptor to the extracellular matrix; its binding to the matrix recruits focal adhesions to two NPxY motifs, the tyrosine phosphorylation sites in the cytoplasmic domain. Studies found that replacing tyrosines (Y) with phenylalanines (F) in the motif of β1 integrin displayed little developmental or ...
