BIRC5 and neoplasm: Looking for a strategy aimed at improving the activity of selinexor in TNBC experimental models, in this study we investigated the effect exerted by the ectopic expression of miR-34a, an onco-suppressive miRNA known to be down-regulated in different tumor types [17], including TNBC [18], and previously reported to target survivin [19,20,21], on the in vitro and in vivo activity profile of selinexor.
