LC-MS of Human Blood of Pancreatic neuroendocrine tumors

Pancreatic Neuroendocrine tumors are challenging to diagnose and often detected at advanced stages due to lack of specific and sensitive biomarkers. This study utilized proteomics as a valuable approach for cancer biomarker discovery, therefore, mass spectrometry-based proteomic profiling was conducted on plasma samples from 12 subjects (3 controls; 9 PanNET patients) to identify potential proteins capable of effectively distinguish PanNET from healthy controls. 13.2% of proteins were uniquely identified in PanNET, while 60% were commonly expressed in PanNET and controls. 17 proteins exhibiting significant differential expression between PanNET and controls were identified with downstream analysis.
