Project description:Intervention type:DRUG. Intervention1:Huaier, Dose form:GRANULES, Route of administration:ORAL, intended dose regimen:20 to 60/day by either bulk or split for 3 months to extended term if necessary. Control intervention1:None.
Primary outcome(s): For mRNA libraries, focus on mRNA studies. Data analysis includes sequencing data processing and basic sequencing data quality control, prediction of new transcripts, differential expression analysis of genes. Gene Ontology (GO) and the KEGG pathway database are used for annotation and enrichment analysis of up-regulated genes and down-regulated genes.
For small RNA libraries, data analysis includes sequencing data process and sequencing data process QC, small RNA distribution across the genome, rRNA, tRNA, alignment with snRNA and snoRNA, construction of known miRNA expression pattern, prediction New miRNA and Study of their secondary structure Based on the expression pattern of miRNA, we perform not only GO / KEGG annotation and enrichment, but also different expression analysis.. Timepoint:RNA sequencing of 240 blood samples of 80 cases and its analysis, scheduled from June 30, 2022..

Project description:Enhancers regulating Th cell specific cytokine gene expression were studied and identified. However, Il9 regulating enhancer was not identified yet. Active enhancers are characterized with P300, STATs binding and active histone modifications such as H3K4me1 and H3K27ac. Based on P300 ChIP seq analysis, we narrowed down enhancer candidates for Il9 gene expression.
Project description:This study aims to identify genomic contacts with the nucleolus (nucleolar associated domains, NADs). We established a novel methodology that we applied to identify NADs in embryonic stem cells (ESCs). The results revealed unprecedented distinct layers of genome compartmentalization that are distinguished according to gene expression and chromatin states thereby providing novel insights into basic principles of genome organization and its role in gene expression and cell function.
Project description:There is clear evidence that clinical genetic counseling for hereditary cancer saves lives and relieves anxiety. Our aim is to identify novel genes that predispose to familial colorectal cancer. We follow the empirical gene discovery paradigm by identifying high-risk families diagnosed with the same cancer in several family members. Such families and samples are identified from the world’s largest biobank of 16,000 familial cancers in Szczecin. For this study we identified 15 colorectal cancer families with several affected family members. Germline DNA from cases and unaffected family members are sequenced genome-wide at the DKFZ core facility, one of Europe’s top sequencing centers. Based on the proof-of-principle study on melanoma, a single family may allow identification of a high-risk variant when the new genome-wide sequencing technology is applied. In that example, the detected variant targeted a transcription factor binding site which turned out to be the most common gene variant in melanoma yet described, with implications to prognosis. The present project aims at cancer prevention in identifying novel high-risk variants for which predictive gene testing can be established.
Project description:Here we characterized a splicesomal sub-complex including the proteins RBM17, U2SURP and CHERP, and found that these proteins physically interact and regulate reciprocal posttranslational stability; individually knocked down, they cause widely overlapping and consistent splicing and gene expression changes of transcripts enriched for RNA processing factors.
Project description:Deregulation of canonical Wnt/beta-catenin pathway is one of the earliest events in the pathogenesis of colon cancer. Mutations in APC or CTNNB1 (beta-catenin gene) are highly frequent in colon cancer and cause aberrant stabilization of b-catenin, which activates the transcription of Wnt target genes by binding to chromatin via the TCF/LEF transcription factors. Here we report an integrative analysis of genome-wide chromatin occupancy of b-catenin by chromatin immunoprecipitation coupled with high-throughput sequencing (ChIP-seq) and gene expression profiling by microarray analysis upon RNAi-mediated knockdown of beta-catenin in colon cancer cells (GSE53656). Immunoprecipitated samples from human colon cancer SW480 cells with antibodies against beta-catenin and control IgG respectively were used for ChIP-seq experiments.
