HIF ‑1α attenuates neuronal apoptosis by upregulating EPO expression following cerebral ischemia‑reperfusion injury in a rat MCAO model.
HIF‑1α attenuates neuronal apoptosis by upregulating EPO expression following cerebral ischemia‑reperfusion injury in a rat MCAO model. Int J Mol Med. 2020 Jan 28;: Authors: Li J, Tao T, Xu J, Liu Z, Zou Z, Jin M Abstract Hypoxia‑inducible factor‑1α (HIF‑1α) is a key transcriptional factor in response to hypoxia and is involved in ischemic stroke. In the present study, the potential for HIF‑1α to inhibit neuronal apoptosis through upregulating erythropoietin (EPO) was investigated in a transient middle cerebral artery occlusion (tMCAO) rat stroke model. For this purpose, a recombinant ...

Therapeutic potential of AAV9-S15D-RLC gene delivery in humanized MYL2 mouse model of HCM
This study is focused on aspartic acid-to-valine (D166V) mutation in the myosin regulatory light chain, RLC (MYL2 gene), associated with a malignant form of HCM. Since myosin RLC phosphorylation is critical for normal cardiac function, we aimed to exploit this post-translational modification via phosphomimetic-RLC gene therapy. We hypothesized that mimicking/modulating cardiac RLC phosphorylation in non-phosphorylatable D166V myocardium would improve heart function of HCM-D166V mice. Adeno-associated virus, serotype-9 (AAV9) was used to deliver phosphomimetic human RLC variant with serine-to-aspartic acid substitution at S...

Adenoviruses-mediated RNA interference targeting cytosolic phospholipase A2 α attenuates focal ischemic brain damage in mice.
Adenoviruses-mediated RNA interference targeting cytosolic phospholipase A2α attenuates focal ischemic brain damage in mice. Mol Med Rep. 2018 Feb 15;: Authors: Wu H, Liu H, Zuo F, Zhang L Abstract Cerebral ischemia injury is a clinical, frequently occurring disease, which causes a heavy burden on society and families. It has been demonstrated that cytosolic phospholipase A2α (cPLA2α) is significant in neurological injury caused by ischemic brain injury, and inhibition of cPLA2α may reduce stroke injury. In the present study, the role of cPLA2α was investigated in a mouse model of middle cerebral...
