چکیده
Several cationic antimicrobial peptides demonstrate promising anticancer effects. We have recently described the anticancer properties of LTX-315, a novel synthetic anticancer peptide, against syngeneic B16 melanomas. LTX-315 induced a complete regression of B16 melanomas and systemic protective immune responses following intralesional administration of the peptide.

The oncolytic peptide LTX-315 kills cancer cells through Bax/Bak-regulated mitochondrial membrane permeabilization
LTX-315 has been developed as an amphipathic cationic peptide that kills cancer cells. Here, we investigated the putative involvement of mitochondria in the cytotoxic action of LTX-315. Subcellular fractionation of LTX-315-treated cells, followed by mass spectrometric quantification, revealed that the agent was enriched in mitochondria. LTX-315 caused an immediate arrest of mitochondrial respir...

Host defense peptides (HDPs) are naturally occurring molecules found in most species, in which they play a significant role in the first line defense against intruding pathogens, and several HDPs have been shown to possess anticancer activity. Structure-activity relationship studies on the HDP bovine lactoferricin revealed a de novo design of a nonamer peptide LTX-315, with oncolytic properties...

Host defense peptides are naturally occurring peptides that have an important function in innate immune responses in almost every life form. Recently it has been documented that several host defense peptides have anticancer activity. Based on a naturally occurring host defense peptide, we have do novo designed the short chemically modified peptide LTX-315. We have demonstrated that LTX-315 indu...

The oncolytic peptide LTX-315, which has been de novo designed based on structure-activity relationship studies of host defense peptides, has the ability to kill human cancer cells and induce specific anticancer immune response when injected locally into tumors established in immunocompetent mice. The oncolytic effect of LTX-315 involves perturbation of plasma membrane and the mitochondria with...

Background Host defense peptides (HDPs) are naturally occurring molecules found in most eukaryotic species, in which they play a significant role in the first line of defense against pathogens. Several HDPs have shown to possess anticancer activity. Structure-anti-cancer activity relationship studies on the HDP bovine lactoferricin has resulted in the design of a short oncolytic 9-mer peptide, ...
