found that most of PPARβ/δ target genes are upregulated in tumor-associated macrophages (TAMs) from ovarian carcinoma patients, activation of PPARβ/δ target genes by polyunsaturated fatty acids which act as potent PPARβ/δ agonists in macrophages contributes to the pro-tumorigenic polarization of ovarian carcinoma TAMs (240). Here, PPARD is linked to ovarian carcinoma.
