To further explore the clinical correlation between CDC37L1 and PPIA and their association with clinicopathological parameters of HCC patients, we accessed the expression of CDC37L1 and PPIA in a tissue microarray containing 80 pairs of HCC and adjacent normal tissues derived from patients who received sorafenib treatment after surgery via immunohistochemistry (IHC) staining. The gene discussed is PPIA; the disease is hepatocellular carcinoma.
