LOXL4 and neoplasm: The intratumor injection of either miR-193a-3p’s agomiR (into 5637)/antagomiR (into H-bc tumor) indeed led the expected changes of both SRSF2 and LOXL4 proteins in tumor tissues (Figure 6E), and consolidate the conclusion that miR-193a-3p promotes both the growth and chemoresistance of the BCa cell derived tumor xenografts in nude mice.
