From a bioinformatic analysis of proteomic datasets from eighty-one patients with breast cancer in The Cancer Genome Atlas (TCGA) [30], we found that expression of multiple RNA binding proteins, including RBMS1, DDX6, SND1, and ACO1, was increased in the basal subtype of breast cancer, also known as triple-negative breast cancer (TNBC), as compared to other subtypes (Fig. S1A). This evidence concerns the gene SND1 and triple-negative breast carcinoma.
