Project description:Desmoid tumors (DT) are rare, benign, fibroblastic neoplasm with challenging histological diagnosis. DTs can occur sporadically or associated with the familial adenomatous polyposis coli (FAP). Most sporadic DTs are associated with β-catenin gene (CTNNB1) mutations, while mutated APC gene causes FAP disease. MicroRNAs (miRNAs) are involved in many human carcinogenesis. The miRNA profile was analyzed by microarray in formalin-fixed, paraffin-embedded (FFEP) specimens of 12 patients (8 sporadic, 4 FAP-associated) and 4 healthy controls. One hundred and one miRNAs were dysregulated, of which 98 miRNAs in sporadic DTs, 8 in FAP-associated DTs, 5 were shared by both tumors. Twenty-six miRNAs were then validated by RT-qPCR in 23 sporadic and 7 FAP-associated DT samples matched with healthy controls. The same qPCR method was used to evaluate the CTNNB1 mutational status in sporadic DTs. The correlation between sporadic DTs and miRNA expression showed that miR-21-3p increased in mutated versus wild-type DTs, while miR-197-3p was decreased. The mRNA expression of Tetraspanin3 and Serpin family A member 3, miR-21-3p targets, and L1 Cell Adhesion Molecule, miR-197-3p target, was also evaluated. CTNNB1 mutations associated to miRNA dysregulation could help histological diagnosis of sporadic DTs and could affect the genesis and the progression of this disease.

Project description:In CRC, 1) to identify epigenetic changes at inter-tumor and intra-tumor level, and 2) to relate intra-tumor clonality to clinical, molecular and histopathologic parameters. From 79 FFPE tumors, 3 different regions were macrodissected: invasive front (IF), digestive tract surface (DTS) and central bulk (CB). Clinical, molecular, and histopathologic parameters were stablished. Epigenetic analysis was performed using Infinium 450K beadchip (Illumina) and R statistics. Intra-tumor regions clustered together by patient. The biggest epigenetic changes were in IF vs DTS/CB. By patient, the most often divergent region was IF (49.4%) comparing with DTS and CB (25.3% in both). It did not correlate with histopathologic, molecular and clinical parameters.Epigenetic clonality is higher at intra-tumor level. The highest changes are observed in IF vs DTS/CB. No association with histopathologic, molecular, and clinical characteristics was found. SNP characterization of 9 patients of teh discovery cohort were hibridized on Infinium HumanOncoArray-500 v1 beadchip, to asses the genetic clonality of the samples among the three intratumoral regions studied.

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..
