Introduction: Syringomyelia (SM) is a heritable disorder causing a fluid filled cavity (FFC) in the spinal cord with a reported overall prevalence of 39 to 46% in the Cavalier King Charles Spaniels (CKCS). Breeders started screening their CKCS with MRI in the Netherlands since 2004 and in Denmark since 2015. The goal of this study was to evaluate the effect of MRI-based selection in breeding on the prevalence of SM.

ATXN3 has multiple functions, such as regulating transcription or controlling genomic stability after DNA damage. Here we report the role of ATXN3 in chromatin organization during unperturbed conditions, in a catalytic-independent manner.

SETD8 regulates the recruitment of 53BP1 to sites of DNA damage by controlling histone H4K20 methylation. Moreover, SETD8 levels are tightly regulated in a cell cycle-dependent manner by ubiquitin-dependent proteasomal degradation.

It is critical for several important functions in the cell, and therefore dysregulation of USP7 can contribute to tumorigenesis.
Objectives: Alterations in the USP7 protein have been identified in various malignancies of humans.
Article Synopsis
- Significant advancements have been made in identifying COVID-19 patients and detecting immune responses to SARS-CoV-2.
- The study examined the IgG antibody response in COVID-19 patients using dot blot analysis of viral protein fragments, focusing on the N and S proteins.
- Results showed a strong immune response against the N protein and a partial response to a specific segment of the S protein, which may inform future COVID-19 antibody measurement methods and vaccine development.
