Differential Expression Of Circulating Micrornas In Blood And Haematoma Samples From Patients With Intracerebral Haemorrhage
The Journal of international medical research(2016)
摘要
Objective To measure the differential expression of microRNAs (miRNAs) in peripheral blood samples from patients with intracerebral haemorrhage (ICH) and to measure the levels of hsa-miR-21-5p in peripheral blood and haematoma samples from patients with ICH.Methods This case-control study enrolled individuals with ICH in the putamen treated by craniotomy and age- and sex-matched healthy control subjects. Serum miRNA expression profiles were determined in the patient and control groups using miRNA polymerase chain reaction (PCR) arrays. The ICH-related miRNA hsa-miR-21-5p was selected and its differential expression was assessed in peripheral blood and haematoma specimens from patients with ICH compared with peripheral blood samples controls using real-time PCR.Results Seven patients and five control subjects were included in the miRNA expression profile analysis; and 31 patients and 22 control subjects provided samples for the real-time PCR of hsa-miR-21-5p expression. A total of 59 miRNAs were significantly downregulated in patients with ICH. Relative hsa-miR-21-5p levels of 0.43 and 0.31 for peripheral blood and haematoma samples, respectively, were obtained in the patient group compared with the control subjects.Conclusion Hsa-miR-21-5p levels were significantly reduced in both peripheral blood and haematoma samples in patients with ICH.
