Discovery of traditional serrated adenoma by using DSP

To further characterized the serrated pathway, we used the novel Digital Spatial Profiling (DSP) technology and its mRNA Cancer Transcriptome Atlas (CTA) panel, which includes over 1800 target gene, to investigate the underlying gene expression changes and pathways involved in sessile serrated lesion (SSL) and traditional serrated adenoma (TSA), two precancerous lesions to carcinoma in serrated pathway.
