MGP and neoplasm: In the present study, we first identified six potential genes that were specifically upregulated in breast carcinoma, namely N-acetyltransferase 1 (NAT1), matrix Gla protein (MGP), secretoglobin family 2A member 2 (SCGB2A2/mammaglobin-A), LIM homeobox transcription factor 1 beta (LMX1B), transcription factor AP-2 beta (TFAP2B), and transcriptional repressor GATA binding 1 (TRPS1), by bioinformatics analyses using The Cancer Genome Atlas (TCGA) and Clinical Proteomic Tumor Analysis Consortium (CPTAC) databases across 24 different solid tumors.
