Figure 1.

piR-651 was up-regulated in breast cancer tissues and cell lines. (a) The expression of piR-651 in breast cancer tissue and adjacent tissue samples collected from 16 patients (37.93 ± 10.05 years) was detected by Northern blotting. ** P < 0.01, unpaired t test. (b) Relative expression of piR-651 in breast cancer cells and normal breast epithelial cells was detected by RT-qPCR. N = 4, **P < 0.01 compared with Hs-578Bst. #P < 0.05 compared with AU565. $P < 0.05 compared with HCC38 or MCF-7. The difference of the samples between the two groups were analyzed with independent sample t test. The analysis of variance (ANOVA) test was used to evaluate multigroup comparisons of the means
