UBE2B and breast cancer: To analyze the link between Rad6B and Wnt signaling pathway, we used RT2 Profiler PCR SuperArrays to profile the expression of 84-Wnt related genes in vector control, R6B-Zshigh, or R6B-Zshigh/LRP6Δ173 MDA-MB-231 cells, or vector control or pLKO-Rad6BshRNA WS-15 [22] breast cancer cells.
