ABSTRACT
Objective: Microarray chip was used to detect the differentially expressed microRNA (miRNA) in kidney tissues of rats with kidney-Yang deficiency induced by adenine,and its significance was analyzed by bioinformatics method. Method: Rats with kidney-Yang deficiency were induced by intragastric administration of 150 mg·kg-1 adenine in model group, while rats in normal group were given the same amount of saline.Kidney tissues were taken for hematoxylin-eosin (HE) staining pathological sections after anesthesia and blood urea nitrogen (BUN), creatinine (SCr) in blood and 24-hour urinary protein (24U-TP) in urine were measured. μParaflo microfluidic chip technology was used to investigate differential expression miRNA in kidney tissues, and microarray results were verified by Real-time PCR. Bioinformatics database was used to analyze the target genes and functions of differential expression miRNAs. Result: Gene chip results showed that there were 50 differentially expressed microRNAs after modeling. Compared with control group, only 9 miRNAs were highly expressed in kidney tissues with significant difference were detected in model group. Compared with the normal group, the expression of rno-miR-21-5p, rno-let-7i-5p, rno-miR-146b-5p and rno-miR-15b-5p in model group increased significantly(PPPPPConclusion: This experiment found 4 miRNAs involved in the regulation of renal interstitial fibrosis (RIF) and 2miRNAs with unknown functions, which provided a new clue for further analysis of the regulatory network of kidney-yang deficiency.
