dc.description.abstract | Parafibromin is a protein encoded by the oncosuppressor CDC73 gene, whose mutation results in hyperparathyroidism-jaw tumor syndrome (HPT-JT) and parathyroid carcinoma. Down-regulation of parafibromin is linked to lung, gastric, colorectal, and ovarian cancer tumorigenesis. Parafibromin expression was detected by RT-PCR, bioinformatics analysis, Western blot, and immunohistochemistry; and compared with clinicopathological characteristics of breast cancer. CDC73-related genes and pathways were analyzed using bioinformatics analysis. Parafibromin expression was increased in breast cancer compared to normal tissues at both mRNA and protein levels (p<0.05). Among triplenegative breast cancers, it was higher in basal-like 1 than basal-like 2 patients (p<0.05) and mesenchymal than immunomodulatory patients (p<0.05). CDC73 mRNA expression was positively correlated with white race, non-infiltrating immune cells, favorable luminal subtypes of PAM50, and prognosis of breast cancer patients (p<0.05). The differential genes of CDC73 were classified into enzyme inhibitors, peptidase, and keratinization by KEGG (p<0.05). Similarly, it was classified into ribosomes, TGF-β, oxidation phosphorylation, inositol phosphate metabolism, arachidonic acid metabolism, linoleic acid metabolism, ERBB, and VEGF signaling pathways by GSEA (p<0.05). The positively-correlated genes of CDC73 were involved in cell mobility, response to interferon α, nuclear pore and basket, and histone methyltransferase. The negatively-correlated genes of CDC73 were involved in the mitochondrial respiratory chain, thermogenesis, and ribosomes. Parafibromin expression was higher in invasive ductal than lobular carcinoma (p<0.05) and mucinous adenocarcinoma than others (p<0.05). Parafibromin immunoreactivity as an independent factor was positively associated with an increased overall survival rate of breast cancer patients (p<0.05). These findings suggest that up-regulation of parafibromin in breast cancer patients is closely linked to a favorable prognosis. It is involved in tumorigenesis and subsequent progression by regulating metabolism, ribosomes, and cytokines. | es |
