SRSF2 and cancer: This study also provided a new set of genes in this newly identified miR-193a-3p/LOXL4/Oxidative Stress axis as the diagnostic targets for the guided anti-bladder cancer chemotherapy, including the level of the miR-193a-3p gene, both LOXL4 and SRSF2 gene and the key OS pathway associated genes in both cancer tissues and urine sediments.
