Table 2.
The proportion of oocytes (mean ± SD) at GV-arrest, metaphase l or telophase l stages in GV oocytes injected with miR-130b precursor, inhibitor or scramble miRNA and uninjected groups
| Treatment groups | No of GV oocytes | GV-arrest | Metaphase l | Telophase l | Metaphase ll |
|---|---|---|---|---|---|
| miR-130b precursor | 189 | 8.2 ± 0.1 | 8.3 ± 3.3 | 10.1 ± 5.5a | 73.5 ± 10.1a |
| miR-130b inhibitor | 204 | 8.9 ± 3.1 | 6.7 ± 3.9 | 30.1 ± 7.8b | 52.8 ± 4.4b |
| Scramble | 192 | 7.4 ± 0.9 | 6.8 ± 4.1 | 15.3 ± 7.8a | 69.7 ± 9.7a |
| Uninjected control | 191 | 7.3 ± 0.8 | 6.7 ± 2.8 | 13.0 ± 5.9a | 72.3 ± 6.1a |
Different letters of superscripts in the same column indicate significant difference (P ≤ 0.05) between treatment groups. GV Germinal vesicle, SD standard deviation
