Correlation of HAS2-associated gene duplications with biological aggressiveness of mast cell tumors in Chinese Shar-Pei dogs
Cutaneous mucinosis in Shar-Pei dogs is the result of excessive dermal hyaluronan, a protein associated with angiogenesis and tumor cell motility in multiple human and canine neoplasms. Cutaneous mucinosis in Shar-Pei has been associated with gene duplications upstream of the hyaluronic acid synthase 2 gene (HAS2). The objective of this study was to evaluate the relationship between HAS2, cutaneous mucinosis, and features of mast cell tumor (MCT) aggressiveness in Shar-Pei dogs. Biopsies of cutaneous MCTs from 149 Shar-Pei and 100 non-Shar-Pei were graded according to two schemes for canine ...
