Expression of the Wilms’ tumour gene and its association with PPARβ/δ in healthy skin and melanoma of horses.
Abstract: The Wilms' tumour gene (WT1) has previously been described as an oncogene in several neoplasms of humans, including melanoma, and its expression increases cancer cell proliferation. Recent reports associate the expression of the PPARβ/δ gene (peroxisome proliferator-activated receptor beta/delta) with the downregulation of WT1 in human melanoma and murine melanoma cell lines. The aim of this work was to analyse the expression of WT1 and its association with PPARβ/δ in samples of healthy and melanoma-affected skin of horses by immunohistochemistry. WT1 protein expression was detected in healthy skin, mainly in the epidermis, hair follicle, sebaceous gland and sweat gland, while no expression was observed in equine melanoma tissues. Moreover, it was observed that PPARβ/δ has a basal expression in healthy skin and that it is overexpressed in melanoma. These results were confirmed by a densitometric analysis, where a significant increase of the WT1-positive area was observed in healthy skin (128.66 ± 19.84 pixels 106) compared with that observed in melanoma (1.94 ± 0.04 pixels 106). On the other hand, a positive area with an expression of PPARβ/δ in healthy skin (214.94 ± 11.85 pixels 106) was significantly decreased compared to melanoma (624.86 ± 181.93 pixels 106). These data suggest that there could be a regulation between WT1 and PPARβ/δ in this disease in horses.

The research article presents a study on the Wilms’ tumour gene (WT1) and PPARβ/δ gene and their association in healthy and melanoma-affected skin in horses. The study found WT1 expression in healthy skin and PPARβ/δ overexpression in melanoma, suggesting a regulatory relationship between the two in horse melanoma.
Analysing WT1 and its Association with PPARβ/δ
- The study aims to examine the expression of the Wilms’ tumour gene (WT1) and its relationship with the PPARβ/δ gene (peroxisome proliferator-activated receptor beta/delta) in samples of healthy and melanoma-affected skin of horses.
- WT1, previously described as an oncogene in various human neoplasms including melanoma, has been associated with increased cancer cell proliferation.
- Recent studies revealed a link between the expression of the PPARβ/δ gene and the decreased expression of WT1 in human and murine melanoma cell lines.
Detection of WT1 and PPARβ/δ Expressions in Healthy and Melanoma Skin
- The expression of the WT1 protein was found in healthy equine skin, specifically in the epidermis, hair follicle, sebaceous gland, and sweat gland.
- However, no WT1 expression was detected in equine melanoma tissues.
- PPARβ/δ showed a basal expression in healthy skin and was found to be overexpressed in melanoma tissues.
Densitometric Analysis Confirming Expressions
- Densitometric analysis was performed and confirmed the occurrences of WT1 and PPARβ/δ expressions in healthy and melanoma-affected skin.
- A significant increase in the WT1-positive area was observed in healthy skin compared to that in melanoma, whereas a significant decrease in the PPARβ/δ-positive area was noted in healthy skin compared to melanoma.
Suggesting Regulatory Relationship Between WT1 and PPARβ/δ
- The observations and data from this study suggest a potential regulatory relationship between WT1 and PPARβ/δ in horse melanoma.
- While WT1 expression was characteristic of healthy skin, PPARβ/δ overexpression was associated with melanoma, indicating an inverse relationship.
