ABSTRACT
The cathelicidin antimicrobial peptide, LL-37, is a multifunctional peptide with a broad spectrum of antimicrobial activities, such as chemotaxis and neutralizing endotoxins. Previous studies have demonstrated that it LL37 serves a functional role in the development of numerous types of cancer including ovarian, breast, prostate and lung cancer. However, its role in the development of malignant melanoma (MM) remains unclear. To determine the role of LL37 and the potential interaction with Y-box binding protein 1 (YB1) in MM, RNA interference, western blot, reverse transcription-quantitative polymerase chain reaction, MTT and Transwell assays were performed. The current study demonstrated that LL37 induced YB1 expression, and increased tumor cell proliferation, migration and invasion of A375 and A875 MM cell lines. In addition, inhibition of nuclear factorκB (NFκB) attenuated LL37induced YB1 expression. These results demonstrate that, through the upregulation of YB1 expression and the activation of the NFκB signaling pathway, LL37 may promote the malignant progression of MM cells in vitro.
