Figure 2. CircFOXK2 is involved in the metastasis of BC. (A) Expression of circFOXK2 in BC tissues in the early or advanced stage. (B) Expression of circFOXK2 in BC tissues or paired liver metastasis. (C) Expression of circFOXK2 in liver metastasis, as detected by RNA FISH assay. Scale bar: 30 μm. Data were represented as mean ± SD. Each experimental group had at least three replicates. ^*p < 0.05, ^**p < 0.01, ^***p < 0.001.
