چکیده انگلیسی
This study was designed to investigate the role of obesity in canine malignant mammary tumours (CMMTs), by assessing aromatase expression and the regulatory roles of immune mediators such as cyclo-oxygenase-2 (COX2), prostaglandin E2 (PGE2), nuclear factor kappa beta (NF-κB), hypoxia inducible factor-1α (HIF-1α) and adipokines (i.e. leptin) in lean, optimal body weight, overweight and obese animals. Clinicopathological data, including the breed, body weight, body condition score and age and neutering status, were collected, together with histopathological characteristics (i.e. histological types, grading and lymphatic invasion). To determine the expression of each factor, immunohistochemistry was conducted with 60 samples of malignant CMMTs. CMMTs from overweight and obese animals had significantly elevated levels of PGE2, and aromatase expression correlated significantly with PGE2, NF-κB and leptin expression. However, no significant difference was observed in terms of histopathological characteristics. The results suggest that PGE2, a known obesity-related immune mediator, could be upregulated in CMMTs from overweight and obese animals. In addition, PGE2, NF-κB and leptin influenced the expression of aromatase, as observed in women.
