DUSP7 and breast cancer: By “sponge adsorption” of let-7a-5p, circABCB10, which is highly expressed in paclitaxel-resistant breast cancer tissues, can increase the expression of the Dual-specificity phosphatase 7 (DUSP) gene, prevent the activation of the MAPK signaling pathway, decrease breast cancer cell apoptosis, and cause paclitaxel resistance [145].
