HAMLET, a tumoricidal molecular complex from human milk
HAMLET (Human a-lactalbumin made lethal to tumor cells) is a protein-lipid complex that kills tumor cells and immature cells but spares healthy, differentiated cells. The complex is formed from partially unfolded a-lactalbumin and oleic acid, both of which are abundant constituents of human milk. The folding change occurs after removal of Ca2+ from native a-lactalbumin, and the partially unfold...
متن کاملApoptosis-Like Death in Bacteria Induced by HAMLET, a Human Milk Lipid-Protein Complex
BACKGROUND Apoptosis is the primary means for eliminating unwanted cells in multicellular organisms in order to preserve tissue homeostasis and function. It is characterized by distinct changes in the morphology of the dying cell that are orchestrated by a series of discrete biochemical events. Although there is evidence of primitive forms of programmed cell death also in prokaryotes, no inform...
متن کاملProtein receptor-independent plasma membrane remodeling by HAMLET: a tumoricidal protein-lipid complex
A central tenet of signal transduction in eukaryotic cells is that extra-cellular ligands activate specific cell surface receptors, which orchestrate downstream responses. This ''protein-centric" view is increasingly challenged by evidence for the involvement of specialized membrane domains in signal transduction. Here, we propose that membrane perturbation may serve as an alternative mechanism...
متن کاملThe Human Milk Protein-Lipid Complex HAMLET Sensitizes Bacterial Pathogens to Traditional Antimicrobial Agents
The fight against antibiotic resistance is one of the most significant challenges to public health of our time. The inevitable development of resistance following the introduction of novel antibiotics has led to an urgent need for the development of new antibacterial drugs with new mechanisms of action that are not susceptible to existing resistance mechanisms. One such compound is HAMLET, a na...
متن کاملHistone deacetylase inhibitors promote the tumoricidal effect of HAMLET.
Histone deacetylase inhibitors (HDIs) and HAMLET (human alpha-lactalbumin made lethal to tumor cells) interact with histones, modify the structure of chromatin, and trigger tumor cell death. This study investigated how the combination of HDIs and HAMLET influences cell viability, histone acetylation, and DNA integrity. The pretreatment of tumor cells with HDIs was shown to enhance the lethal ef...
