The results showed that PC patients with a high LDLR expression level were associated with a poor prognosis (P=0.003) (Figure 4), and patients with both high LDLR (P=0.001) and HDLBP (P=0.042) expressions exhibited a higher incidence of cancer-related death versus those with low LDLR and HDLBP expressions (Table S2). Here, LDLR is linked to cancer.
