Assessment of mPRs expression demonstrated increased PAQR7 expression in breast tumor tissue compared to normal tissue (Additional file 1: Fig. S1D, left and middle panels), with statistical significance from the entire collection (Additional file 1: Fig. S1D, right panel), supporting previous observations of increased PAQR7 RNA expression in breast cancers [29]. The gene discussed is PAQR7; the disease is breast neoplasm.
