Results .Circ_IRAK3 was highly expressed in BC tissues and cells . To confirm the differential expression of circ_IRAK3 in BC, we detected the level of circ_IRAK3 in 47 pairs of BC tissues and adjacent non-cancerous tissues by qRT-PCR. In comparison to the adjacent non-cancerous tissues, circ_IRAK3 expression was observably higher in BC tissues (Fig.? 1 A). High expression of circ_IRAK3 was associated with TNM grade, lymph node metastasis, and tumor size of BC patients (Table 1 ). Also...
