ASPN, STK3 and BAMBI were all significantly overexpressed at the mRNA level in both canines (p = 0.02175, p = 0.00985, and p = 0.032, respectively) and humans (p = 0.000978, p = 0.019706, and p = 0.010047, respectively) OSA tumours were compared to non-malignant counterparts identified in previous research [43,44]. This evidence concerns the gene STK3 and neoplasm.
