BIRC5 and breast carcinoma: We performed an immunofluorescence staining for falloidyn, a marker of cytoskeleton organization, that binds specifically to F-actin and marks the actin stress fibers in the cell, and survivin, that modulates microtubule nucleation and polymerization, in BT474 human breast cancer cells after treatoment with eribulin, taselisib, ipatasertib or their combination for 24 hours (Figure 6).
