circFAT1 level increased in OX-resistant BC tissues and cells, and that circFAT1/miR-525-5p/SKA1 (Spindle and kinetochore-associated protein 1) axis increased the OX resistance in BC via activation of Neurogenic locus notch homolog protein (Notch) and Wingless/Integrated (Wnt) pathway [104]. The gene discussed is SKA1; the disease is breast cancer.
