Fifteen genes and other transcripts were differentially expressed in the triple negative comparison (10 genes increased and 5 decreased, Table S3F) including peptidoglycan recognition protein 1 (PGLYRP1; 2.99 log2 fold-change; P = 7.64E-04) whose expression may reflect immune cell response to developing breast tumors [41]. Here, PGLYRP1 is linked to breast neoplasm.
