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: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:Cirrhosis and cancers of the upper digestive tract, colorectal and ENT share common risk factors. Liver cirrhosis can change the elimination of cancer drugs.
Precise data on management and outcome of patients with liver cirrhosis undergoing chemotherapy are lacking. Most patients have been excluded from clinical trials evaluating conventional therapies.
The study of tolerance, side effects, and outcome in patients with cirrhosis could help improve chemotherapy management for better tolerance and efficacy.
The main objective is to estimate the frequency of liver cirrhosis among patients evaluated in CPR for ENT, upper digestive or colorectal cancer.
Secondary objective includes the evaluation ofthe impact of cirrhosis on the management of chemotherapy by comparing cirrhotic patients’ outcomes with a control group of matched non-cirrhotic patients.

Project description:Liver disease alters the gut microenvironment by liver-gut axis. To investigate the composition and transcriptome changes of various intestinal cell populations in liver cirrhosis, we delineated a single-cell atlas of the colon from mice treated CCl4 for 6 weeks.
