LFch potential as therapeutic for multiple myeloma

Lactoferrin-derived peptide chimera, LF chimera (LFch) is a synthetic peptide that mimics the functional unit of lactoferrin with antibacterial activity. Since antimicrobial peptides (AMPs) are known to be promising candidates for cancer treatment, in this study, we explored the potential of LFch for the treatment of multiple myeloma (MM), a malignant clonal plasma cell disease of the bone marrow. LFch effectively inhibited MM1S, MM1R, and RPMI8226 multiple myeloma cell growth and induced the early and late phase of apoptosis whereas did not a normal PBMCs. Furthermore, LFch modulated the relative gene expression of survival, apoptosis, and mitochondrial dysfunction at the transcriptional levels.
