RUNX1T1 and breast carcinoma: In contrast, co-culture with CD40L L cells, but not with CDw32 L cells, also partially reversed the cytostatic effect of DOX and ETO in the 2 breast carcinoma cell lines at 72 h, and also after 240 h of culture (not shown), but did not affect the proliferation of breast carcinoma cell lines treated with CDDP, VIN and TAX (Figure 2).
