Our analysis showed significant upregulation of LEDGF/PSIP1 transcript levels in breast tumors in 2 of the 17 Oncomine breast cancer gene microarray datasets, and robust elevation of LEDGF/p75 transcript (2.26 fold, P = 0.037) in the TissueScan Cancer Q-PCR array. Here, PSIP1 is linked to breast carcinoma.
