N2 - Myeloid cell leukemia 1 (Mcl-1) is an anti-apoptotic protein which is overexpressed in variousleukemia and other cancers [1]. Mcl-1 has a very short half-life [2], which has been suggested as amolecular mechanism for cells to switch into either the survival or apoptotic pathways in response todifferent stresses [3]. Recently, it has been demonstrated that downregulation of Mcl-1 by variouspharmacological agents or genetic approaches dramatically increases ABT-737 lethality in variousmalignant cell types [4]. Different strategies for targeting Mcl-1 include (i) small interfering RNA [5](ii) small-molecule inhibitors [6] and (iii) peptide inhibitors [7]. In recent years, therapeuticvaccination with synthetic peptides derived from anti-apoptotic proteins such as Mcl-1 has emergedas a promising strategy against hematological cancers.In this study, 34 overlapping 20-mer peptides, spanning the entire Mcl-1 protein, were adjuvantedwith cationic liposomes [8] and tested in three different mouse strains with varied MajorHistocompatibility Complex (MHC) haplotypes (FVB [H-2q], CB6F1[H-2b/d], B6CBAF1 [H-2b/k])to identify immunogenic CD4+ T-cell epitopes.
