Fig. 7. Markers of apoptotic vulnerabilities in AL amyloidosis.

Fig. 7

a, b Clonal plasma cells isolated from Kappa- and Lambda-predominant AL amyloidosis were isolated and BH3 profiled to measure their a overall level of apoptotic priming via sensitivity to the BIM BH3, BID BH3, and PUMA BH3 peptides and their b dependencies on the pro-survival BCL-2 family proteins BCL-2, BCL-XL, and MCL-1. ce BH3 profiling indicating (c) overall apoptotic priming and d BCL-2 family dependencies in clonal plasma cells from AL amyloidosis patients with t(11;14), and e ex vivo sensitivity to BH3 mimetics. f, g BH3 profiling CD138 + cells from a healthy bone marrow donor showing (f) overall priming and g dependencies on pro-survival proteins compared to clonal AL CD138 + cells. h Dynamic BH3 profiling of normal plasma cells treated with bortezomib for 12 h. i Ex vivo sensitivity of normal plasma cells to the combination treatment of bortezomib with indicated BH3 mimetics. P-values were calculated using two-way ANOVA with Holm–Sidak’s adjustment for e.
