PSMP expression in biopsy tissue may be a biomarker for the diagnosis of CAAMR. The expression of PSMP protein was detected by immunohistochemistry (A) and quantified by Image-pro plus software (B). PSMP mRNA level was analyzed by RT-PCR in biopsy tissues (C). Receiver operating characteristic (ROC) curves were used to evaluate the value of PSMP protein expression in the prediction of CAAMR from Control and CAMR patients (D) in graft biopsies. *p ≤ 0.05, **p ≤ 0.01, and ***p ≤ 0.001. ns, no significance.
