Relative miR-214 and PTEN protein expression levels in rat hippocampus were measured by qRT-PCR and western blot analysis.

<p>A: Quantitative analysis of hippocampus miR-214 levels in Control, K<sub>1</sub> and K<sub>2</sub> group, miR-214 expression were obviously decreased in K<sub>2</sub> group rats (n = 6; *p<0.05 compared with Control group or K<sub>1</sub> group). B: Representative western blots of hippocampus PTEN protein levels. C: Quantitative analysis of hippocampus PTEN levels in Control, K<sub>1</sub> and K<sub>2</sub> group, relative PTEN protein expression levels were obviously increased in K<sub>2</sub> group rats (n = 6; *p<0.05 compared with Control group or K<sub>1</sub> group). GAPDH, glyceraldehyde 3-phosphate dehydrogenase.</p>
