Abstract:

Objective

MicroRNA with significantly differential expression and targeted regulation of Vitamin D receptor(VDR) in Tuberculosis were screened by High-throughput sequencing and bioinformatics methods, whichprovided the further study of Vitamin D anti-tuberculosis mechanism and clinical application.

Method

According to the inclusion and exclusion criteria, 5 patients with definite diagnosis of tuberculosis and 5 non-tuberculosis volunteers were selected as the study group and control group. Peripheral blood mononuclear cells(PBMC) of the two groups were collected as clinical samples. After total RNA was extracted, high-throughput sequencing technology was used to detect the differential expression of miRNA between the two groups.

Result

The clinical baseline data of 5 tuberculosis patients and 5 non-tuberculosis volunteers were collected, and the homogeneity and heterogeneity of 23 items between the two groups were obtained by statistical analysis. It was found that there were no significatly statistical differences in gender, age, smoking and drinking habits between the two groups. Body mass index (BMI), total cholesterol (TC), hemoglobin (Hb) albumin (ALB), globulin (GLB) and total protein (TP) in the study group were lower than those in the control group with significatly statistical differences(P<0.05). A total of 1560 miRNAs were screened out by miRNA sequencing. Through stratified cluster and comprehensive volcanic map analysis, 23 miRNAs with the most significant (P<0.05) differences were found in the case group, among which 15 were down-regulated(∣LOG2FC∣>1) and 8 were up-regulated(FC>1). In short, Combined with bioinformatics predictions, two miRNAs targeted VDR that differentially expressed in tuberculosis patients were screened out: hsa-miR-326(P<0.05、FC=1.37)、hsa-miR-654-5p(P<0.05、∣LOG2FC∣=1.06).

Conclusion

These two differentially expressed miRNAs mentioned abovemay be potential diagnostic markers and new therapeutic targets for tuberculosis.This found provides a new strategy and feasible direction for the prevention and treatment of Tuberculosis.
