UCHL1 and breast cancer: A separate Kaplan–Meier plot analysis performed using large publicly available datasets (e.g. GEO (Affymetrix microarray only), European Genome-phenome Archive (EGA) and The Cancer Genome Atlas (TCGA)) suggested that high UCHL1 mRNA expression did not correlate with shorter survival in ER− and PR− breast cancers (Fig S2).
