Abstract:
OBJECTIVETo find the potential serum specific miRNAs with diagnostic value in early pancreatic cancer and study the alteration of miRNAs levels in the process of origin and development of pancreatic cancer and discuss the diagnostic value of miRNAs in early pancreatic cancer.
METHODSDMBA-induced rat model was established. The miRNAs expression profile of early stage was screened out by microarray. And confirmation study was performed.
RESULTSThe 35 and 12 abnormally expressed miRNAs were acquired in pancreatic tissue and blood respectively. There were no significant differences between normal pancreas and pancreatic cancer in expressions of hsa-let-7c, hsa-miR-122-5p, hsa-miR-142-5p, hsa-miR-199a-3p and hsa-miR-451a (P > 0.05).
CONCLUSIONSmiRNAs are the potential biomarkers of early pancreatic cancer. The establishment of the miRNAs expression profile has build the foundation of exploring the molecular mechanism of origin of pancreatic cancer.
