The 39 genes included 11 early-response genes (FOS, JUN, RGS1), six stress-response/immune genes (DUSP1, GADD45B, ATF3), four snoRNA (SNORD3C, SNORD3D), four haemoglobin (HBA2, HBB) and five genes associated to breast cancer progression (SIK1, TOB1, BHLHB2). Here, BHLHE40 is linked to breast cancer.
