Project description:The purpose of this study is to evaluate gene expression changes and identify characteristics in patients with Pseudomyxoma Peritonei (PMP). We analyzed RNA-seq data to identify gene signatures associated with PMP development using 19 fresh frozen tissue samples including 12 PMPs (discovery cohort). Through analyzing the differences in gene expression between normal tissues and PMP, we identified statistically significant gene groups, and confirmed the biological functions and pathways associated with these gene groups.
Project description:Through single-cell transcriptomic profiling of five samples with Pseudomyxoma Peritonei (PMP) , we identified ten distinct cell type-specific clusters, including an epithelial cell community with significantly increased expression of canonical epithelial molecules, and a mesenchymal cell community with notably higher expression of established mesenchymal molecules, supporting the presence of both epithelial and mesenchymal molecular characteristics in PMP disease.
Project description:The purpose of this study is to evaluate gene expression changes and identify characteristics in patients with Pseudomyxoma Peritonei (PMP). We analyzed RNA-seq data from 34 formalin-fixed paraffin-embedded (FFPE) samples, including 25 PMPs (validation cohort), to identify gene signatures associated with the development of PMP. We confirmed protein expression levels using a tissue microarray (TMA) cohort of PMP patients. Through analyzing the differences in gene expression between normal tissues and PMP, we identified statistically significant gene groups, and confirmed the biological functions and pathways associated with these gene groups.
