Retro-inverso form of BPIs showed enhanced intracellular stability and maintained biological activity. A. The sequences of the D-retro-inverso (DRI) forms of BCL10-P2 and BCL10-P4. B. Western blot showing BCL10 in HBL1 cells to compare the pharmacokinetics between BCL10-P4 and DRI-BCL10-P4 treatments. C. EM micrographs showing that DRI-BCL10-P2/P4 inhibited Bc10 filament formation in vitro. D. Dose-response curves of DRI-BCL10-P2/P4 in HBL1, TMD8 and OCI-LY1 cells. The GI50s are indicated. The experiments were performed independently in triplicate. The data are presented as the means ± SD. Statistics: one-way ANOVA with Dunnett's multiple comparison test. E. Western blot showing IKKβ, p-IKKβ, IκBα, and p-IκBα in the HBL1, TMD8 and OCI-LY1 cells treated with DRI-BCL10-P4 at the indicated concentrations for 12 h. F. Apoptosis rate was analysed by annexin V+/PI- and annexin V+/PI+ staining of cells treated with DRI-BCL10-P4 for 24 h. The y axis shows the sum of the percentage of annexin V+/PI- and annexin V+/PI+ cells. The data are reported as the mean ± SD of two independent experiments.
