However, there were 22 (15.82%) tumor tissue cores with low LEDGF/p75 and high ERp57 protein levels, and 27 (19.42%) tumor tissue cores with high LEDGF/p75 and low ERp57 protein levels, indicating that the correlation between the expressions of these proteins was not complete (Fig 9C). The gene discussed is PSIP1; the disease is neoplasm.
