A gene expression profiling study to identify distinct molecular markers in formalin-fixed, paraffin-embedded samples of Pseudomyxoma Peritonei [FFPE]

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. We analyzed RNA-seq data from 34 formalin-fixed paraffin-embedded (FFPE) samples, including 25 PMPs (validation cohort).
