(B, C) Volcano plots of DEGs identified via label-free quantitative proteomics in PANC-1 and AsPC-1 cells. (D) Western blot analysis of MTERF3 in PANC-1 and AsPC-1 cells treated with Agrimol B for 24 h. (E) Differences in MTERF3 expression between normal tissues and cancer tissues in the UCSC Xena database. (F) Kaplan-Meier analysis of MTERF3 expression and overall survival in 64 patients with PDAC. (G, H) CCK-8 assay in PDAC cells transfected with vector or oeMTERF3 following treatment with or without Agrimol B.
