While natively folded alpha-lactalbumin (ALA) associates with galactosyl transferase in the mammary epithelium to produce lactose [3], partially unfolded alpha-lactalbumin can be stabilized with oleic and linoleic acids from human milk (and bovine, to a less extent) to form the HAMLET and BAMLET complexes (human and bovine alpha-lactalbumins made lethal to tumor cells), which have attracted significant attention due to their apparent therapeutic properties and ability to selectively kill tumor cells [2,4,5]. The gene discussed is LALBA; the disease is neoplasm.
