Mean-Centering Alters Pathway-Based Transcriptomic Comparisons of Feline and Mouse Kidney Disease.

Clinical Context

Peer-reviewed veterinary literature continues to shape everyday decision-making for feline patients, especially when new evidence clarifies diagnosis, treatment selection, monitoring, or clinical outcomes.

What the Study Evaluated

A study published in International journal of molecular sciences in 2026 evaluated mean-Centering Alters Pathway-Based Transcriptomic Comparisons of Feline and Mouse Kidney Disease..

Key Findings

Transcriptomic similarity is used to characterize disease models, but a comparison can change when the same responses are summarized differently. We examined mean-centering before pathway averaging in 16 disease states from one feline chronic kidney disease cohort and two mouse kidney injury models, using 2016 genes detected in both species' proteomes and 422 overlapping pathways. Among 87 state pairs without shared control samples, uncentered pathway means separated same-species from cross-species pairs with an area under the curve of 0.868; removing each state's mean across genes first reduced this to 0.511. The uncentered value was higher...

Why It Matters for Veterinary Professionals

For veterinary professionals, the practical value of this work lies in how the findings may support more structured clinical assessment, clearer monitoring, and more informed decisions for feline patients.

Practical Interpretation

The results should be interpreted in the context of the study design, population, inclusion criteria, and clinical setting. Application in practice should consider patient-specific risk factors, available diagnostics, local standards of care, and clinician judgment.

Clinical Takeaway

Overall, the study adds useful evidence for clinicians seeking to align daily practice with current veterinary research while maintaining a balanced, case-by-case approach.
