However, in vitro work in glioma cell lines and ex vivo studies in BCLL, has shown that APRIL stimulates proliferation and inhibits apoptosis in response to a wide range of stimuli, including CD95L, TRAIL and cytotoxic drugs and survival in B-CLL cells involves NFκB activation [15-19,31-34]. The gene discussed is TNFSF10; the disease is B-cell chronic lymphocytic leukemia.
