Expression of B-myb in breast cancer patient specimens and cell lines. A. Expression of IBP in primary breast cancer and matched lymph node tumors (×400); B. Kaplan-Meier plots of B-myb expression in 20 cases of breast cancer patients. Overall survival rate was performed by log-rank test. P < 0.05 indicate significant differences between two groups; C and D. Expression of B-myb in breast cancer cell lines. Equal amounts of proteins from seven non- or low metastatic breast cancer cell lines (MDA-MB-468, T47D, MCF-10A and MCF-7) and two highly metastatic breast cancer cell lines (MDA-MB-231 and HS578T) were evaluated by immunoblot analysis with antibodies against B-myb and glyceraldehyde 3-phosphate dehydrogenase (GAPDH).
