SIN3B and triple-negative breast carcinoma: We also utilized the PROGgeneV2 database (watson.compbio.iupui.edu/chirayu/proggene/database/index.php) [23, 24] with similar results of high expression of SIN3A and low expression of SIN3B correlated with longer relapse-free survival specifically in triple negative breast cancers (hazard ratios = 0.35 and 2.66; logrank P = 0.0489 and 0.0587 respectively for SIN3A and SIN3B) (Figure 5E, 5F).
