Electroacupuncture alleviates ulcerative colitis by targeting CXCL1: evidence from the transcriptome and validation.

Project description:BackgroundWe aimed to use transcriptomics, bioinformatics analysis, and core gene validation to identify the core gene and potential mechanisms for electroacupuncture (EA) treatment of ulcerative colitis (UC).Materials and methodsEA was performed in mice after induction of UC via dextran sodium sulfate. Body weight, disease activity index (DAI), colon length, and hematoxylin-eosin of the colon tissue were used to evaluate the effects of EA. Mice transcriptome samples were analyzed to identify the core genes, and further verified with human transcriptome database; the ImmuCellAI database was used to analyze the relationship between the core gene and immune infiltrating cells (IICs); and immunofluorescence was used to verify the results.ResultsEA could reduce DAI and histological colitis scores, increase bodyweight and colon length, and improve the expression of local and systemic proinflammatory factors in the serum and colon of UC mice. Eighteen co-differentially expressed genes were identified by joint bioinformatics analyses of mouse and human transcriptional data; Cxcl1 was the core gene. EA affected IICs by inhibiting Cxcl1 expression and regulated the polarization of macrophages by affecting the Th1 cytokine IFN-γ, inhibiting the expression of CXCL1.ConclusionsCXCL1 is the target of EA, which is associated with the underlying immune mechanism related to Th1 cytokine IFN-γ.

Methylation profiling in Ulcerative colitis

Project description:The series was designed to identify the different methylated single CpGs involved in the pathophysiology of ulcerative colitis. A cohort of n=20 monozygotic twins, discordant for ulcerative colitis was selected. Illumina and Nimblegen platforms were used.

Transcription profiling of human ulcerative colitis colonic mucosa to define an ulcerative colitis preinflammatory state

Project description:The samples are a part of a study aiming at diagnosing ulcerative colitis from genome-wide gene expression analysis of the colonic mucosa. Colonic mucosal samples were collected as endoscopic pinch biopsies from ulcerative colitis patients and from control subjects. Samples with and without macroscopic signs of inflammation were collected from the patients. Experiment Overall Design: The series contain eight UC samples with macroscopic signs of inflammation, 13 UC smaples without macroscopic signs of inflammation, five control subjects.

DNA methylation in a validation cohort of colon mucosa samples from individuals with Crohns' disease or ulcerative colitis and normal controls

Project description:Genome wide DNA methylation profiling of Crohn's disease, ulcerative colitis, and normal colon mucosa samples. The Illumina Infinium HumanMethylation450 BeadChip v1.1 was used to obtain DNA methylation profiles across 482,421 CpGs in colon mucosa samples. Samples came from 5 Crohn's disease affected, 5 ulcerative colitis affected, and 12 normal individuals. One ulcerative colitis sample was assayed before and after treatment with infliximab and mesalamine.
