In summary, we have demonstrated that miR-181a expression is upregulated in H [2]O [2] -treated H9c2 cells and that inhibition of miR-181a confers cardiac protection against oxidative stress -induced H9c2 cell apoptosis through the direct inhibition of Gpx1 expression and ROS generation, which are important for the maintenance of mitochondrial membrane integrity and the inhibition of mitochondrial apoptotic pathway under oxidative stress conditions. [score:15]
We found that miR-181a is upregulated in cardiomyocytes with oxidative stress and that the downregulation of miR-181a significantly inhibited the H [2]O [2] -induced cellular apoptosis, ROS production, mitochondrial structure disruption, and activation of key signaling proteins in the mitochondrial apoptotic pathway.

We found that the downregulation of miR-181a expression protected against the H [2]O [2] -induced injury of H9c2 cells by restoring the alterations of H9c2 morphology and nuclear condensation, inhibiting the production of ROS and blocking LDH release and MDA production, two indicators of oxidative stress -induced injury [33]. [score:8]

Overall, the expression patterns of miRNAs fell into four main categories: (1) Enriched in early embryonic stages, especially at E10 and E13 and decreased gradually during development (i. e. the rno-miR-181 family); (2) Enriched late postnatally, especially at P14 and P28, and tended to increase over time (i. e. rno-miR-29a and rno-miR-128); (3, 4) Peaked around neonatal stage (P0), either highest peak or lowest peak. [score:4]
The expression patterns of some miRNAs observed in our study are consistent with what were observed in previous studies by using the blot-array and Northern blot assays, i. e. miR-125b, miR-9, and miR-181a [6], as well as miR-29a, miR-138 and miR-92 [53]. [score:2]
