    Proteotype classification of metastatic and localized renal cell carcinomas for prognosis and therapy response

  • Popis výsledku v původním jazyce

    Renal cell carcinoma (RCC) represents a serious oncological disease with the second highest incidence in the Czech Republic across the world. Reliable molecular predictive and prognostic biomarkers for RCC are mostly unavailable, namely at protein level. To quantify proteins associated with pro-tumorigenic and pro-metastatic mechanisms in RCC, we first generated a comprehensive RCC-specific spectral library of targeted proteomic assays for 7960 protein groups (FDR=1%) [1]. Second, we have applied data independent acquisition mass spectrometry (DIA-MS) on QExactive HF-X LC-MS system and analyzed a well-characterized set of metastatic RCC tumors (training cohort n=53, validation cohort n=22) and adjacent non-cancerous tissues (n=17) a part of which responded and a part did not respond to tyrosine kinase inhibitor (TKI) treatment. We have identified and validated single protein biomarker with a poor response to TKI but not with tumor grade. Functional assays using CRISPR/Cas9 knockdown confirmed its role in metastatic potential of 786-0 cells. Third, we analyzed a well-characterized set of initially localized RCC tumors (n=86) of which a half exhibited a relapse in &lt;5 years after diagnosis. We have identified a single potential biomarker as well as protein classifiers able to predict the relapse, for which we have developed targeted proteomics assays for further validation and routine quantification. CRISPR/Cas9 knockdown confirmed the role of the key protein in cell migration in 786-0 cells, supporting its role in metastatic potential of RCC. In a summary, next generation proteomics based on DIA-MS is a powerful tool to classify RCC tissues, to identify prognostic biomarkers and alternative therapeutic targets.
