JAK2 and breast cancer: reported that circNOL10 actives the JAK2/STAT5 pathway in BC by sponging miR‐767‐5p and thus suppressing EMT, migration and invasion.[31] In addition, circEGFR promotes the EMT of triple‐negative breast cancer via the absorption of miR‐1299.[32] Furthermore, circRNAs could also facilitate chemoimmunotherapy resistance and immune evasion in BC.
