IL6 and breast cancer: Similar with our findings, a recent study linked the high expression of hsa_circRNA_0006528 to advanced tumour‐node‐metastasis stage and poor outcomes in breast cancer, while inhibition of this circRNA delayed cancer development.19 Analogously, up‐regulation of hsa_circRNA_0072995 is determined in breast cancer cells; in contrast, the silencing of hsa_circRNA_0072995 restrained aggressive malignant behaviours in breast cancer.20 Moreover, hsa_circRNA_002178 silencing inhibited inflammation in vivo through reducing TNF‐α and IL‐6 levels and prevented tumour growth.
