Abstract
AIM: To detect serum miR-21 and miR-1247-5p expression levels in patients with primary liver cancer, and to assess their clinical and diagnostic value in primary liver cancer.
METHODS: Serum samples were collected from patients with primary liver cancer and healthy volunteers. The expression levels of miR-21 and miR-1247-5p in serum samples were measured by real-time quantitative PCR (qRT-PCR).
RESULTS: A total of 82 clinical samples were collected, including 41 from patients with primary liver cancer and 41 from healthy volunteers. qRT-PCR results showed that compared with healthy controls, miR-21 expression rose significantly and miR-1247-5p expression significantly declined in patients with primary liver cancer. Serum levels of miR-21 and miR-1247-5p had no correlation with alpha fetoprotein (P > 0.05).
CONCLUSION: Compared with healthy controls, patients with primary liver cancer have significant changes in serum miR-21 and miR-1247-5p expression. Detection of serum miR-21 and miR-1247-5p may be useful for the diagnosis of primary liver cancer.
