Figure 5. Expression fold change of miR-181a, miR-23a, miR-26b and PR mRNA in each breast cancer tumor sample and its’ adjacent normal tissue, in PR mRNA up-regulation samples A.-C. (n = 10) and in PR mRNA down-regulation samples D.-F. (n = 8).
Levels of miRs and PR mRNA were determined by quantitative RT-PCR analysis. The comparative threshold cycle (Ct) method was used for quantification. Values are presented in log scale. Lines represent the linear regression analysis; R2 (Goodness-of-fit) for the linear regression analysis and p-values are indicated.
