Urinary carbonic anhydrase IX splicing messenger RNA variants in urogenital cancers

摘要

Background: To identify molecular biomarkers for tumor diagnosis and monitoring of disease progression, several noninvasive tests on liquid biopsy have been proposed for different cancers including those of urogenital origin. Among biomarkers, carbonic anhydrase IX (CAIX) has gained attention as it regulates extracellular pH and induces cytoplasmic alkalization contributing to malignant progression and poor treatment outcome. Works on tissues suggested the potential use of CAIX as a tumor biomarker for urogenital malignancies, but only few studies have been performed on its detection in urine.
