IL-32 expression in primary myeloma cells is associated with inferior survival, cell division, and oxidative phosphorylation
(A) Overall survival of IL-32 expressing patients (10th percentile) compared with nonexpressing patients (90th percentile) in the IA13 CoMMpass dataset P = 8.9e-5, using Cox proportional-hazards regression model.
(B) IL-32 expression in individual patients at diagnosis and first relapse in RNA-sequenced CD138+ cells from CoMMpass IA13. Significance was determined by Wilcoxon signed-rank test.
(C) GO-analysis of the upregulated genes (Benjamini-Hochberg-adjusted p value <0.05; log2 fold change >0 for up-regulated genes) in IL-32-expressing patients (10th percentile) compared with IL-32 nonexpressing patients (90th percentile). Top significantly enriched biological processes upregulated in IL-32 expressing patients are shown. The GO terms are ordered by the Benjamini-hochberg adjusted p values. See also Tables S3 and S4.
(D) Correlation between IL32 and a proliferative index gene signature (calculated as the sum of expression values of the gene set as described in Hose et al. (2009).
(E) GO-analysis of the downregulated genes (Benjamini-Hochberg-adjusted p value <0.05; log2 fold change <0 for down-regulated genes, respectively) in IL-32-expressing patients (10th percentile) compared with IL-32 nonexpressing patients (90th percentile). Top significantly enriched biological processes downregulated in IL-32 expressing patients are shown. The GO terms are ordered by the Benjamini-Hochberg adjusted p values. See also Tables S3 and S4.
