mRNA expression of miR-206 and Cx43 in breast cancer tissue
| Tissue | miR-206 | Cx43 | ||
|---|---|---|---|---|
| Ct value (mean ± SD) | 2−ΔΔCt | Ct value (mean ± SD) | 2−ΔΔCt | |
| NTs | 32.510 ± 1.420 | 1 | 29.490 ± 0.790 | 1 |
| CTs | 19.550 ± 0.940 | 0.045* | 16.820 ± 1.400 | 0.039‡ |
| HMs | 15.030 ± 0.830 | 0.022*† | 18.900 ± 0.890 | 0.042‡ |
| PMs | 16.470 ± 0.910 | 0.029*† | 17.370 ± 0.930 | 0.032‡ |
*P<0.05, compared with miR-206 NTs subgroup; †P<0.05, compared with miR-206 CTs subgroup; ‡P<0.05, compared with Cx43 NTs subgroup. miR-206 mRNA in CTs, HMs and PMs was significantly lower than that in NTs (P<0.05), miR-206 mRNA in HMs and PMs was lower than that in CTs (P<0.05). NTs: Normal tissues; CTs: Cancer tissues; HMs: Hepatic metastasis; PMs: Pulmonary metastases; SD: Standard deviation; Cx43: Connexin 43; miR-206: MicroRNA-206; mRNA: Messenger RNA; SD: Standard deviation.
