Oxaliplatin is commonly used in managing malignancy, including colorectal cancer. While treatment often fails due to decreased drug sensitivity, the mechanisms involved are not clear. In this study, we investigate how exosomal miR-19b participates in oxaliplatin sensitivity and then prove that miR-19b down-regulates oxaliplatin sensitivity of sw480 cells. We found that suppressing the secretion of exosomal miR-19b with gw4869 promotes sw480 cell oxaliplatin sensitivity. Our combined results demonstrate for the first time that miR-19b regulates the oxaliplatin sensitivity of sw480 cells and provides a unique mechanism mediated by gw4869 to modulate oxaliplatin sensitivity by suppressing exosomal miR-19b release.
