Project description:Liver cirrhosis is one of the leading causes of decreased life expectancy worldwide. However, the molecular mechanisms underlying the development of liver cirrhosis remain unclear. In this study, we performed a comprehensive analysis using transcriptome sequencing to explore the genes, pathways, and interactions associated with liver cirrhosis. We performed transcriptome sequencing of blood samples from patients with cirrhosis and healthy controls (1:1 matched for sex and age). For transcriptome analysis, we screened for differentially expressed miRNAs and mRNAs, analyzed mRNAs to identify possible core genes and pathways, and performed co-analysis of miRNA and mRNA sequencing results. And we validated differentially expressed microRNA (miRNA) and mRNAs using real-time quantitative polymerase chain reaction. Using a systems biology framework, We identified miRNAs and mRNAs that were differentially expressed in the blood of cirrhotic patients and healthy controls. And explored associated pathways as well as disease-specific networks.
Project description:Liver cirrhosis is one of the leading causes of decreased life expectancy worldwide. However, the molecular mechanisms underlying the development of liver cirrhosis remain unclear. In this study, we performed a comprehensive analysis using transcriptome and metabolome sequencing to explore the genes, pathways, and interactions associated with liver cirrhosis. We performed transcriptome and metabolome sequencing of blood samples from patients with cirrhosis and healthy controls (1:1 matched for sex and age). For transcriptome analysis, we screened for differentially expressed miRNAs and mRNAs, analyzed mRNAs to identify possible core genes and pathways, and performed co-analysis of miRNA and mRNA sequencing results. And we validated differentially expressed microRNA (miRNA) and mRNAs using real-time quantitative polymerase chain reaction. In terms of the metabolome, we screened five pathways that were substantially enriched in the differential metabolites. Next, we identified the metabolites with the most pronounced differences among these five metabolic pathways. We performed receiver operating characteristic curve analysis of these five metabolites to determine their diagnostic efficacy for cirrhosis. Finally, we explored possible links between the transcriptome and metabolome. Using a systems biology framework, We identified miRNAs and mRNAs that were differentially expressed in the blood of cirrhotic patients and healthy controls. And explored associated pathways as well as disease-specific networks. Additionally, We identified possible common pathways in the transcriptome and metabolome that can reveal coherent changes in cirrhosis from the transcriptional level to the metabolic level, which can be further studied from multiple perspectives.
Project description:Gene profiling of hepatocytes in early and advanced cirrhotic Rats Two-condition experiment, Advanced cirrhosis vs Control liver, Advanced cirrhosis vs Early cirrhosis. Biological replicates: 5 Advanced cirrhosis, 5 Early cirrhosis, 5 control liver. Each hepatocyte was isolated independently. One replicate per array.
Project description:Genome-wide DNA methylation profiling of cirrhosis and dysplastic liver samples. The Illumina Infinium 450k Human DNA methylation BeadChip was used to obtain DNA methylation profiles across approximately 485,577 CpGs sites. Samples included 130 cirrhosis and 8 exhibiting dysplasia. The manuscript includes an integrative analysis of these samples along with samples from normal liver and HCC already deposited under GSE63898.
Project description:We used the Flex single-cell RNA sequencing platform (10x Genomics) to investigate the transcriptomic differences of hepatocytes between healthy and liver cirrhosis liver samples obtained from resected tissues (non-tumorous regions) of patients with colorectal cancer liver metastases and patients with hepatocellular carcinoma accompanied by liver cirrhosis.
