SLC22A5 expression in breast cancer. a SLC22A5 expression in breast cancer cell lines as determined by qRT-PCR. b SLC22A5 expression in ER-positive and ER-negative cell lines. Left panel qRT-PCR data of this study; right panel cDNA microarray dataset [48]. c SLC22A5 expression in breast tumor tissue specimens from 15 studies including a total of more than 2,000 patients. Studies 1–15 are from the clinical microarray datasets [33–47]. d The correlation between SLC22A5 and ER expression in breast tumor tissue specimens. Shown is the correlation data from the largest dataset, comprised of 295 patients [42]. Analyses of other datasets also generated similar results (data not shown)
