In some cancer studies (Table S1; GSE4536, GSE17891, GSE41258) SALL2 levels inversely correlated with the expression levels of both CCNE1 and CCND1. Altogether, the R2 data analysis showed more consistent inverse correlation between SALL2 and CCNE1 expression in breast cancer tissues. The gene discussed is CCNE1; the disease is breast carcinoma.
