Panel A: Lower body weight at 12 weeks of age was observed in mammary carcinoma susceptible (diamonds) compared to Mcs1b resistant females (squares) with DMBA and without (P < 0.0001 and P = 0.0007, respectively). Body weight was significantly higher in susceptible females that received DMBA compared to without (P < 0.0001). Panel B: Rat Mier3 transcript levels were significantly higher in DMBA-induced mammary carcinomas (triangles) compared to non-diseased mammary gland tissue (circles, P = 0.0120). Mean ± SD are graphed for each variable. Panel C: Human MIER3 was significantly higher in breast carcinomas compared to pathologically normal breast tissues. Oncomine (www.oncomine.org, reference 41 of main text) was used to query The Cancer Genome Atlas (cancergenome.nih.gov) gene expression database. Shown are box plots of log2 median centered MIER3 transcript levels for invasive ductal breast carcinomas (IDBC, n=392) and invasive lobular breast carcinomas (ILBC, n=36) compared to pathologically normal breast tissues (Breast, n=61). *P < 0.05. †P = 0.0569.
