Our analysis suggests a mechanistic mo del, using Bdnf and miR-15b expression levels in dying and surviving cells as an example, for how injury-dysregulated miRNAs could induce differential cell death in adjacent cells that are subjected to the same stressor: because of stochastic fluctuations in Bdnf expression in individual neurons, suppression of Bdnf expression by TBI -induced miRNAs, such as miR-15b, would push the cell below a critical threshold in some cells and result in cell death (Fig.   4). [score:10]
Although a consistent trend was observed - adding the LNA miR-15b inhibitor to the miR-15b mimic returned luciferase expression levels closer to that of control plasmids in every experiment - the noise and variability in Bdnf expression levels prevented the restored expression from reaching statistical significance (Supplementary Fig.   7B). [score:9]
High levels of miR-15b in dying neurons negatively correlate with a validated target, BdnfIPAs miRNA target filter showed that in dying neurons miR-15b has the largest number (166) of predicted gene targets among the approximately 2000 TBI-dysregulated genes that were validated by microarray analysis [4]. [score:8]
miR-15b -mediated suppression of random fluctuations in expression levels of pro-survival target genes, such as Bdnf, could lower the threshold for cell survival and result in neurodegeneration after TBI. [score:7]
Nevertheless, in aggregate, these data combined with the decreased Bdnf levels in laser captured dying neurons (microarray data) and the increased expression of miR-15b in dying neurons (ISH) and increased trends in expression of miR-15b (microfluidic qPCR) support the predicted miR-15b regulation of Bdnf. [score:6]
In comparison to a scrambled miRNA LNA probe (showing only background staining and serving as a negative control probe) and a U6 (small nuclear RNA probe which does not share homology with miRNA sequences available in miRBase) probe that labels all neurons (Supplementary Fig.   5A–C), we found that miR-15b expression is highly upregulated in many dying, FJ+ neurons in all hippocampal subfields (CA1, CA3, dentate gyrus [DG]) and in dying cortical neurons (Fig.   3A,B). [score:6]
IPAs miRNA target filter showed that in dying neurons miR-15b has the largest number (166) of predicted gene targets among the approximately 2000 TBI-dysregulated genes that were validated by microarray analysis [4]. [score:6]
One limitation of these experiments is that although we tried to measure miRNA expression in small numbers of laser captured neurons using microfluidic qPCR analysis, the noise and variability in the miRNA expression data prevented us from definitive conclusions other than that the trends were in the same direction, i. e. higher expression of miR-15b in dying neurons. [score:6]
Transfections (three separate experiments) were performed in triplicate by adding 10 ul of transfection complex containing 0.5 ul Lipofectamine 2000 (Invitrogen), 100 ng of Bdnf miRNA Target Sequence 3′UTR expression clone (GeneCopoeia), 60 nmol/L miR-15b mimic (Dharmacon), or 37 nmol/L antisense LNA oligo (Exiqon). [score:5]
Inset shows expression levels (from separate microarray experiments) of miR-15b in hippocampus of traumatic brain injured (TBI) rats and expression levels of Bdnf in pools of laser capture microdissected dying and surviving hippocampal pyramidal neurons after TBI. [score:5]
Although virtually all FJ+ neurons in the DG and cortex expressed high levels of miR-15b, we found that not all dying, FJ+ neurons in the CA1-CA3 subfields had high levels of miR-15b and conversely, we found miR-15b expressing neurons that were not FJ+; this supports our current hypothesis (see discussion) that gene dosage determines neuronal death, not any specific gene. [score:5]
Since the miR-15b seed binding site is among the most highly conserved (Supplementary Fig.   7A), we used a GeneCopoeia plasmid construct containing the Bdnf 3′ UTR and performed dual luciferase reporter assays to find further evidence that miR-15b directly regulates Bdnf expression. [score:4]
To validate its role in promoting neurodegeneration after TBI, we used in situ hybridization (ISH) with a locked nucleic acid (LNA), digoxigenin-labeled antisense probe to determine if miR-15b expression was increased in dying or surviving neurons in TBI brain sections. [score:3]
One of the predicted targets of miR-15b is Bdnf, a gene which is essential for cell survival, neuroplasticity, and cognitive functions [23]. [score:3]

More importantly, the miRNAs analyzed in this study not only included the miRNAs like Let-7a, miR-15b, miR24, miR-100 and miR-125 which may suppress the expression of cyclins A and B, and miRNAs such as Let-7a, miR24 and miR-125 which may regulate activity of CDK1, but also miRNAs such as miR-181a, miR-221 and miR-222 which can target CDK inhibitors [30– 32].
