The invention discloses an application of a Glypican-1 protein in the diagnosis of pancreatic cancer, a detection method of a Glypican-1 positive exosome concentration, and a use of the detection method. A nano-plasma enhanced scattering (nPES) detection technology can be used to quantify exosomes in serum, an exosome extracting process is omitted, the characteristic antigen of the exosomes is used as a target, and the antigen and a corresponding antibody carrying gold nanoparticles form an antigen-antibody complex in order to obtain exosomes, and the amount of the exosomes is reflected by using the light radiation principle of the gold nanoparticles. The Glypican-1 is a pancreatic cancer-derived exosome biomarker, and the content of Glypican-1 positive exosomes in blood plasma has specific specificity even in early pancreatic cancer, so the exosome content index can be used to diagnose the pancreatic cancer, and the exosome level is closely related to the staging and progression of pancreatic cancer patients. Experiments prove that the method using the nPES detection technology to detect the content of the Glypican-1 exosomes in the serum is concise and accurate, and has better sensitivity and specificity than CA19-9 in the diagnosis of the pancreatic cancer.

Pathways underlying pancreatic tumorigenesis and an hereditary pancreatic cancer gene

There are currently few therapeutic options for patients with pancreatic cancers and new insights into the pathogenesis of this lethal disease are urgently needed. To this end, we performed a comprehensive analysis of the genes altered in 24 pancreatic tumors. First, we determined the sequences of 23,781 transcripts, representing 20,583 protein-encoding genes, in DNA from these tumors. Second, we searched for homozygous deletions and amplifications using microarrays querying ~one million single nucleotide polymorphisms in each sample. Third, we analyzed the transcriptomes of the same samples using SAGE and next-generation sequencing-by-synthesis technologies. We found that pancreatic cancers contain an average of 63 genetic alterations, of which 49 are point mutations, 8 are homozygous deletions, and 6 are amplifications.; Further analyses revealed a core set of 12 regulatory processes or pathways that were each genetically altered in 70 % to 100 % of the samples. The data suggest that dysregulation of this core set of pathways is responsible for the major features of pancreatic tumorigenesis.
