HPLC-MS/MS analysis of plasma samples from patients with colorectal cancer


ABSTRACT: We sought to identify a characteristic profile of proteins in blood plasma samples taken from patients with colorectal cancer using mass spectrometry. We obtained mass spectrometry data of 38 samples from patients with colorectal cancer and 41 samples from healthy volunteers and the data analysis were carried out using panoramic ultra-high resolution mass spectrometry. We carried out a comparative analysis for two series "case" and "control" of protein profiles, differently expressed proteins and proteins with posttranslational modifications.

<b>Background:</b> Colorectal cancer (CRC) at a current clinical level is still hardly diagnosed, especially with regard to nascent tumors, which are typically asymptotic. Searching for reliable biomarkers of early diagnosis is an extremely essential task. Identification of specific post-translational modifications (PTM) may also significantly improve net benefits and tailor the process of CRC recognition. We examined depleted plasma samples obtained from 41 healthy volunteers and 28 patients wi  ...[more]
