[The Significance of miR-122 in Early Screening of Hepatitis B Infection in Blood Donors].
Objective: To study the correlation between miR-122 and early HBV infection and analyze its application value in early infection of voluntary blood donors.
Methods: A total of 150 samples from voluntary blood donors in Fujian Blood Center from May 2021 to July 2022 were collected and divided into group N (normal group), group E (ELISA single positive group), and group D (both ELISA and nucleic acid positive group), and the general information of the three groups of blood donors was collected. Total RNA was extracted from the three groups of samples, and the expression level of miR-122 was detected by qRT-PCR. The expression differences of miR-122 among the three groups of samples were statistically analyzed, and the correlation between the expression level of miR-122 in group D and its HBV DNA copy number was analyzed. The miRNA database was used to predict the potential target genes of miRNA and perform bioinformatics analysis.
Results: There was no statistical difference in gender, education level, and occupation distribution among the three groups, but the age distribution and number of blood donations among different groups were statistically significant. Compared with group N, the relative expression levels of miR-122 in the plasma of group E and group D were significantly downregulated (P < 0.05); the relative expression level of miR-122 in group D was more significantly downregulated than that in group E (P < 0.001). Pearson correlation analysis showed that the expression level of miR-122 in group D was negatively correlated with the HBV-DNA copy number (R2=-0.804,P < 0.01). Two potential target genes were screened using the miRNA database: ALDOA(aldolase A) and PKM (pyruvate kinase). GO analysis results showed that the potential target genes of miRNA mainly involved in biological processes including cell homeostasis and regulation of transcriptional processes.
Conclusion: Downregulation of miR-122 expression is closely related to early HBV infection and replication activity.
