Diagnostic validation of the urine albumin-to-creatinine ratio for early renal disease in healthy dogs and dogs with chronic kidney disease.

Importance: This paper highlights the urine albumin-to-creatinine ratio (UAC) as a valuable biomarker for the early detection of chronic kidney disease (CKD) in dogs. The UAC effectively distinguishes between healthy dogs and those with CKD, particularly in the early stages, and enhances diagnostic accuracy when used alongside other renal biomarkers.

Objective: To evaluate the utility of the UAC as a biomarker for early CKD diagnosis in dogs and examine its correlation with other renal biomarkers in a large-scale clinical study.

Whole-exome and whole-transcriptome sequencing of canine mammary gland tumors.

Studies of naturally occurring cancers in dogs, which share many genetic and environmental factors with humans, provide valuable information as a comparative model for studying the mechanisms of human cancer pathogenesis. While individual and small-scale studies of canine cancers are underway, more generalized multi-omics studies have not been attempted due to the lack of large-scale and well-controlled genomic data. Here, we produced reliable whole-exome and whole-transcriptome sequencing data of 197 canine mammary cancers and their matched controls, annotated with rich clinical and biological features.
