FTL and pancreatic neoplasm: Exosomes were recovered from urine of five pancreatic cancer patients and five healthy controls using phosphatidylserine molecularly imprinted polymers (PS-MIPs), and proteomic analysis by mass spectrometry showed that SLC9A 3R1, SPAG9, and ferritin light chain (FTL) were upregulated in pancreatic cancer patients, suggesting their potential diagnostic markers for pancreatic cancer [77].
