The review presents a summary of knowledge on canine genome research using the DNA microarray technique - a new tool in molecular biology. Canine genome was sequenced in 2005, and since then numerous studies on gene expression in various tissues and organs as well as in different physiological or pathological conditions have been published. Canine DNA microarray has been used in research on neoplastic diseases (e.g. brain tumor), kidney diseases (Alport syndrome, hypertension in obese dogs), cardiac diseases (atrial fibrillation, dilation of the heart) and cartilage diseases. This technique has also enabled the analysis of gene expression in acute phase response and in renal tubular epithelial cell line (MDCK) stimulated by hepatocyte growth factor.
