MiRNA expression-based, potential mechanism of a herbal medicine formula HTG in treating dyslipidaemia rats

ABSTRACT: Potential mechanism was discovered through expression profiling of a total of 3545 miRNAs in liver of rats fed with high fat diet after HTG treatment. MiRNAs in liver of rats(3 group, normal fat diet group, 3, high fat diet group, 3, high fat diet + HTG treatment, 3) were detected, and differentially expressed miRNAs were analyzed to reveal potential mechanism of HTG in treating dyslipidaemia.

Project description:Background: Canmei formula (CMF) is a traditional Chinese medicine compound with definite effect on the prevention and treatment of colorectal adenoma (CRA). It can prevent the transformation of intestinal inflammation to cancer. This study explored the mechanism of action of CMF in anti-CRA using multi-omics techniques. Method: Mice were randomly divided into 4 groups: blank group (Control), high-fat diet (HFD) + AOM/DSS colorectal adenoma model (ADH) groups, Canmei formula treatment group (ADH-CMF) and sulfasalazine treatment group (Sul). Except for the blank group, ADH model was established in the other 3 groups by intraperitoneal injection with AOM reagent, and then mice was given 2.5%DSS in free drinking water and high-fat diet. The mice in the blank group and ADH group were intragastrically perfused with normal saline, and the mice in the other 2 groups were treated with corresponding drugs for 20 weeks. During this period, the changes of physical signs of mice in each group were observed. The differentially expressed genes and proteins in the Control group, ADH group and ADH-CMF group were detected by RNA-seq transcriptome sequencing and Tandem Mass Tags (TMT) quantitative proteomics. After the combined analysis and verification. The key targets were analyzed by gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG). Results : A total of 2548 differential genes were obtained by transcriptomics analysis, and 45 differential proteins were obtained by proteomics analysis. The results of proteomics data and experimental verification showed that CMF mainly acted on the Phospholysine Phosphohistidine Inorganic Pyrophosphate Phosphatase (LHPP) target. GO analysis showed that the targets of CMF were involved in the biological processes such as cellular process, metabolic process and biological regulation. KEGG analysis showed that those genes were involved in oxidative phosphorylation, cell senescence, and Metabolic pathways. Studies have shown that Lhpp overexpression of Lhpp impeded Colorectal cancer cell growth and proliferation in vitro, and was associated with a change in PI3K/AKT activity.
