Association of steroid and xenobiotic receptor (SXR) and multidrug resistance 1 (MDR1) gene expression with survival among patients with invasive bladder carcinoma

What's known on the subject? and What does the study add? SXR and MDR1 are known as responsible for chemo and radiotherapy resistance in some cancers, like kidney cancer (MDR1). Invasive bladder cancer is an aggressive disease, with different behaviour upon its tumoral stage, and also within the same tumoral stage, therefore molecular markers are sought. This study shows a new molecular marker, which has shown as a predictor for bad prognosis...
