| Outline of Final Research Achievements |
We looked for biomarker of FAP in plasma miRNA to detect existence of FAP and associated comorbidities. We compared plasma from five FAP patients before total proctocolectomy and three healthy volunteers using next generation sequence. Candidates included mir143-5p (7.6 times increase), mir143-3p (6.2 times increase), mir96-5p (10.9 times increase), mir183-5p (2.9 times increase), mir885-5p (one-eighth decrease). Among these candidates, we validated mir-143 because mir143-3p demonstrated high copy number in plasma. Decrease of mir143 in polyp of FAP patients was also reported. We measure relative expression of mir143 in eight FAP patients included three patients assessed by NGS. Relative expression of mir143 was 1.48, 1.28, 1.9, 1.46 and 0.76 in FAP patients before surgery. Relative expression of mir143 was 0.42, 0.44 and 0.2 in FAP patients after surgery. These data indicated mir143 expression might decrease after surgery, which meant polyposis influenced mir143 expression.
