According to the previous studies that ARMC1 is mainly localized to the mitochondrial, it could be seen in the results of immunofluorescence that ARMC1 in invasive ductal breast carcinoma and lobular breast carcinoma were localized at the both inner mitochondrial membrane and outer mitochondrial membrane (Figures 5(d)–5(e)). This evidence concerns the gene ARMC1 and breast lobular carcinoma.
