Aberrant post-translational modifications in endosomal trafficking are potential therapeutic targets to avert therapy resistance in solid cancers Dysregulation of PTM-regulated endosomal interactions presents an opportunity to block oncogenic signalling from multiple receptors by targeting common trafficking pathways

摘要
Drugs targeting a single TK/RTK in the treatment of solid cancers has not had the same success seen in blood cancers. This is, in part, due to acquired resistance in solid cancers arising from a range of mechanisms including the upregulation of compensatory RTK signalling. Rather than attempting to inhibit individual compensatory RTK-requiring knowledge of which RTKs are upregulated in any given tumour-strategies to universally inhibit signalling from multiple RTKs may represent an effective alternative. Endosomal trafficking of RTKs is a common conduit that can regulate signalling from multiple RTKs simultaneously. As such, we posit that targeting endosomal trafficking-in particular, aberrant post-translational modifications in cancers that contribute to dysregulated endosomal trafficking-could inhibit oncogenic signalling driven by multiple RTKs and pave the way for the development of a novel class of inhibitors that shift the trafficking of RTKs to inhibit tumour growth.
