GLG1 and colorectal carcinoma: Importantly, in contrast to many studies on organelle proteomics, we here provide not only a detailed list of the protein content of these organelles and the dysregulated proteins in CRC metastasis, but we also provide data validating the results of selected proteins by WB, IF, IHC, and ELISA, showing for GLG1 a remarkable association of its protein levels in plasma to late CRC stages that could be used as a predictive marker of CRC aggressiveness.
