ERBB2-MT group has an elevated proportion of (S+G2+M) stages and the ERBB2-MT tumor has a higher p-AKT level. (A) In cycle distribution, the ERBB2-MT group showed an elevated proportion of (S+G2+M) stages compared with ERBB2-WT when exposed to lapatinib (t=14.97, P<0.05). (B) Under lapatinib+perifosine exposure, the G2+S+M proportion was significantly decreased in the ERBB2 overexpressed groups compared with NC, while no difference was found between WT and MT (t=0.25, P>0.05). (C) Immunohistochemistry staining of tumor sections from two groups of ERBB2+ BC patients. Both groups of patients had a clear positive expression of ERBB2 (and p-ERBB2), while the mutant group exhibited a dramatically higher expression level of p-AKT.
