The circRNA circIFI30 promotes progression of triple-negative breast cancer and correlates with prognosis


Figure 2. circIFI30 is up-regulated in TNBC and associated with the progression and poor prognosis of TNBC patients. (A) Relative expression of circIFI30 in TNBC tissues and adjacent non-tumor tissues was detected by qRT-PCR (n = 38). (B) Relative expression of circIFI30 in cell lines was determined by qRT-PCR. (C) ROC curve was applied to evaluate the diagnostic value of circIFI30 for TNBC. (D) Representative images of circIFI30 expression in TNBC tissues were detected by ISH assays. Scale bar, 100 μm. (E) Dot distribution graph of circIFI30 ISH staining scores was shown in TNBC patients with different pathological grades. (F) Kaplan-Meier survival curve of overall survival in 78 patients with TNBC according to the circIFI30 expression. Patients were stratified into high expression and low expression group by median expression. Data were showed as mean ± SD, *P < 0.05, **P < 0.01, ***P < 0.001.
