4f-SAMMY-seq (Sequential Analysis of MacroMolecules Accessibility) and total RNA-seq data from prostate biopsies of 25 chemo-naïve patients (7 healthy biopsies and 18 tumor biopsies)

We used a groundbreaking epigenomic profiling technique developed in our laboratory, the 4f-SAMMY-seq, along with RNA-seq on 7 healthy biopsies and 18 prostate tumor biopsies. Our study represents the first direct examination of chromatin organization in patient-derived prostate biopsies. Leveraging differences in chromatin architecture, we identified a novel Prostate Cancer transcriptional signature associated with a favorable prognosis.
