Mutation or deletion of the deubiquitinase USP7 causes Hao-Fountain syndrome (HAFOUS), which is characterized by speech delay, intellectual disability, and aggressive behavior and highlights important unknown roles of USP7 in the nervous system. Here, we conditionally delete USP7 in glutamatergic neurons in the mouse forebrain, triggering disease-relevant phenotypes, including sensorimotor deficits, impaired cognition, and aggressive behavior. Although USP7 deletion induces p53-dependent neuronal apoptosis, most behavioral abnormalities in USP7 conditional knockout mice persist following p53 loss.

From Vision to Reality: The EU's Pharmaceutical Reforms and the Path to Improved Access.

Pharmacoecon Open

January 2025

Department of Health Policy and Medical Technology Research Group, LSE Health, London School of Economics and Political Science, London, UK.

Disparities in access to oncology medicines in European Union (EU) member states can impact patient outcomes profoundly, with availability and timely access varying significantly across and within member states. This paper discusses the intersection of the new European Health Technology Assessment Regulation (HTAR), the provisions of the proposed pharmaceutical legislation and their potential impacts on access to oncology medicines across EU member states. The HTAR, seeking to standardise the clinical evaluation of new medicines, has the potential to streamline the evaluation process but also risks oversimplifying diverse national healthcare needs.

Purifying selection is a critical factor in shaping genetic diversity. Current theoretical models mostly address scenarios of either very weak or strong selection, leaving a significant gap in our knowledge. The effects of purifying selection on patterns of genomic diversity remain poorly understood when selection against deleterious mutations is weak to moderate, particularly when recombination is limited or absent.
