In this study, we identified the influence of long-term hypoxia stress on lung development and showed that the miR-15a, downregulation of HIF-1, was responsive to the oxygen concentration and induced mesenchymal ablation through direct inhibition of the antiapoptotic gene chicken bcl-2 by binding to a unique target region. [score:10]
bcl-2 is a target gene of miR-15a but not miR-16 in chicken lung tissues under hypoxiamiR-15a and miR-16 negatively regulate bcl-2 by directly binding to a particular sequence in the 3′-UTR of bcl-2 and inhibiting its translation [21], [31]. [score:9]
Our observation of hypoxia -induced miR-15a expression (Fig. 1B) and reduced Bcl-2 protein levels at E19 (Fig. 2C) indicated an inverse relationship between miR-15a and Bcl-2 protein expression, which suggested a causative role for miR-15a in the downregulation of bcl-2. However, as a cluster member of miR-15a, miR-16 was identified as hypoxia insensitive. [score:8]
Taken together, these results suggested that the lung appeared resistant to apoptosis at E18, which is likely the result of upregulation of Bcl-2. However, at E19, the time of further lung development, the tissues became more sensitive to the oxygen concentration, and apoptosis was induced by the hypoxia -induced upregulation of miR-15a. [score:8]

miR-15a and miR-16, two members of the miR-15a/16 cluster, play a role in proapoptosis regulation by inhibiting the translation of the antiapoptotic protein Bcl-2 via binding to the 3′-untranslated region (3′-UTR) of bcl-2 mRNA [21]. [score:8]

To determine whether the peak value of miR-15a expression was lung specific or was a systemic reaction to hypoxia and whether expression of miR-15a was the same as that of miR-16, we performed real-time PCR for miR-15a and miR-16 using chick embryo lung, heart, brain and liver at E16 and E19. [score:5]

At E18, the hT group showed significant upregulation of miR-15a that remained relatively high and stable through d3 (Fig. 1B). [score:4]
Together, the results suggested that chicken miR-15a decreased chicken bcl-2 translation by directly acting on a miR-15a–specific response element in the 3′-UTR of chicken bcl-2 mRNA and that this effect may be different in chicken bcl-2 as compared with that in human bcl-2. Chicken miR-16, another member of the cluster, did not affect bcl-2 regulation. [score:4]
At E19, the time at which the respiratory CCGS develops, miR-15a was also upregulated in hW and nT chickens. [score:4]
We hypothesize that the induced ablation of mesenchymal cells may involve HIF-1 as a hypoxia sensor, which then indirectly decreases Bcl-2 protein levels by inducing miR-15a expression. [score:4]
Therefore, either inhibition of miR-15a or activation of HIF-1 or Bcl-2 may potentially be therapeutic options for preventing hypoxia -induced lung damage and may reduce death at particular stages of chick embryo development. [score:4]
To further verify whether miR-15a or miR-16 repressed chicken bcl-2 by binding directly to the predicted binding site in its 3′-UTR as shown in human cells [31], we analyzed the complementation of the chicken bcl-2 mRNA (NM_205339.1) and chicken miR-15a/16 using four different prediction algorithms: TargetScan [33], RNA22 [34], DIANA [35], [36], and PicTar [37].
