Project description:Long-read proteogenomic data was used to create sample-matched protein database for WTC11 sample. This includes many potential alternative protein isoforms (major and minor isoforms) per gene. The IS-PRM method called Tomahto was tested versus DDA to demonstrate improved coverage of isoform-specific peptides. We called this overall method of long-read RNA informed Tomahto targeting LRP-IS-PRM and used it for protein-level evidence of multiple isoforms derived from alternative splicing.

Project description:Colorectal cancer (CRC) is the third most common cancer worldwide and liver metastasis remains the major cause of death in CRC. Extensive genomic analysis provided valuable insight into the pathogenesis and progression of CRC. However, the major proteogenomic characterization of CRC liver metastasis is still unknown. We investigated proteogenomic characterization and performed comprehensive integrative genomic analysis of human colorectal cancer liver metastasis.
