Expression level of miR-142-3p in postnatal striatal development is inversely correlated to D1 receptor protein expression.

<p>(<i>A</i>) Representative western blot which shows the level of D1 receptor protein in mouse brain striatum at P7, P14 and P30. Equal levels of total protein were loaded in each lane of the gel as evidenced by the equivalent amido black staining in the bottom panel. (<i>B</i>) Relative level of miR-142-3p normalized to U6 small nuclear RNA in striatal tissue punches at P7, P14 and P30. The bars represent the mean values ± s.e.m. (n = 3 to 4). *P<0.001, the level of miR-142-3p was significantly higher at P7 when compared to P14 and P30, One Way ANOVA, post hoc SNK test.
