Study Title | Functional metabolomics-based molecular profiling of acute and chronic hepatitis (Liver Metabolomics) |
Study Summary | Non-alcoholic steatohepatitis (NASH) is a metabolic dysregulation triggered by an overload disrupting the hepatic tolerance to external molecules. With the complexity and diversity of hepatitis triggers, no effective clinical classification and treatment are available, and even using the same strategies or approaches for acute and chronic hepatitis. For us, it is really difficult to precisely diagnose and treat hepatitis accordingly. To overcome this challenge, we integrated metabolomic, lipidomics, transcriptomics and other life science frontier technologies for functional metabolomics studies, and pioneered the redefinition of hepatitis at the molecular level. Our findings suggested that acute hepatitis mainly interferes with purine metabolism and amino acids metabolism, while chronic hepatitis mainly causes disruption of hepatic bile acids and lipidome, especially glycerolipids. Based on the liver-gut axis, we also found that the metabolic regulation of the gut microbiota is another key factor for chronic hepatitis development. In conclusion, functional metabolomics enables the cognition of disease occurrence, development and regression from small molecule metabolic modifications and modulations, realizing the ultimate goal of treating diseases and improving population health through regulation of dysregulated metabolism |

Sample Preparation:
Sampleprep ID: | SP002187 |
Sampleprep Summary: | Total lipids were extracted from samples using the Bligh-Dyer method. An aliquot of the organic phase was added to an equal volume of methanol before being loaded onto a DEAE-cellulose column (Wako Chemical) pre-equilibrated with chloroform. After successive washes with chloroform/methanol (1:1, v/v), acidic phospholipids were eluted with chloroform/methanol/HCl/water (12:12:1:1, v/v), followed by evaporation to dryness to yield a residue was soluble in methanol. |
Extraction Method: | the Bligh-Dyer method |
Sampleprep ID: | SP002188 |
Sampleprep Summary: | 100-130 mg liver tissue samples were weighted, 1.2 mL of 80% ice-cold aqueous methanol, which contains 0.001 mg/mL internal standard, and approximately 1 g of glass beads (1.0 mm i.d.) was added into a 2 mL screw-cap plastic microvial. The Mini-BeadBeater-16 (Biospec Products, USA) was used for tissue disruption. Samples were homogenized 3 times for 2 min each, with cooling procedure in between, centrifuged at 20,000 g for 10 min at 4 °C, and the supernatants were mixed with 800 μL of ice-cold acetonitrile and centrifuged again for protein precipitation. The supernatant was filtered through a 0.22 µm organic phase membrane, blown dry in nitrogen, reconstituted in 100 µL of water and transferred to vials for metabolomics assay. |
