In this study, we evaluated the feasibility for the cell-permeable Bax BH3 peptide [Tag peptide (T) bound to Bax BH3 peptide (X) and the fusogenic peptide (P)] expressed and released from the surface of Salmonella enterica serovar Typhimurium strain SL3261 through the MisL autotransporter system (34) (Salmonella enterica L-STXP) to promote apoptosis signaling and the death of NHL tumor cells. This evidence concerns the gene BAX and neoplasm.
