Positive correlations were found between the mRNA levels of BCL3 with some of these target genes, such as TNFAIP3/A20, CCL2, CD274, and CXCL10, in brain lower grade glioma (LGG) and ovarian serous cystadenocarcinoma (OV) samples from TCGA database (Figures 1C,D; Supplementary Figures S1B,C). This evidence concerns the gene CD274 and ovarian serous cystadenocarcinoma.
