In disease-specific survival analysis, increased JCHAIN expression in BRCA, Cervical Squamous Cell Carcinoma and Endocervical Adenocarcinoma (CESC), HNSC, LUAD, and SKCM resulted in good DSS, whereas the inverse was true in GBM and Uveal Melanoma (UVM) (Figure 4B). Here, JCHAIN is linked to glioblastoma.
