Then, we also detected the level of PPARD in clinical BC samples by IHC staining (n = 54; Fig. 3E, F) and qPCR assays (n = 18; Fig. 3G), suggesting that PPARD expression was higher in BC tissues, and was positively correlated with H3K18la expression via Spearman analysis (p < 0.001). The gene discussed is PPARD; the disease is breast cancer.
