Screening circular RNA expression patterns following focal cerebral ischemia in mice.

Oncotarget

Liu C, Zhang C, Yang J, Geng X, Du H, Ji X, Zhao H.
PMID: 29156814
Oncotarget. 2017 Sep 23;8(49):86535-86547. doi: 10.18632/oncotarget.21238. eCollection 2017 Oct 17.

Circular RNAs (circRNAs) have been demonstrated to act as microRNA (miRNA) sponges and they play important roles in regulating gene expression through a circRNA-miRNA-gene pathway. The specific roles of circRNAs in the pathogenesis of cerebral ischemia, however, are still...

Using hormetic strategies to improve ischemic preconditioning and postconditioning against stroke.

International journal of physiology, pathophysiology and pharmacology

Zhao H, Joo S, Xie W, Ji X.
PMID: 23750305
Int J Physiol Pathophysiol Pharmacol. 2013 May 27;5(2):61-72. Print 2013.

Both ischemic preconditioning (IPreC) and ischemic postconditioning (IPostC) trigger endogenous neuroprotective mechanisms in cerebral ischemia. IPreC is defined as a brief ischemia that protects against a subsequent severe ischemia, while IPostC refers to a series of brief cerebral blood...

Ischemic postconditioning for stroke treatment: current experimental advances and future directions.

Conditioning medicine

Chen H, Shen J, Zhao H.
PMID: 34396060
Cond Med. 2020 Apr;3(2):104-115. Epub 2020 May 05.

Ischemic postconditioning (IPostC) protects against brain injury induced by stroke and is a potential strategy for ischemic stroke treatment. Understanding its underlying mechanisms and potential hurdles is essential for clinical translation. In this review article, we will summarize the...

CD4 T cell deficiency attenuates ischemic stroke, inhibits oxidative stress, and enhances Akt/mTOR survival signaling pathways in mice.

Chinese neurosurgical journal

Zhang H, Xiong X, Gu L, Xie W, Zhao H.
PMID: 32832192
Chin Neurosurg J. 2018;4. doi: 10.1186/s41016-018-0140-9. Epub 2018 Nov 08.

BACKGROUND: Inhibition of CD4 T cells reduces stroke-induced infarction by inhibiting neuroinflammation in the ischemic brain in experimental stroke. Nevertheless, little is known about its effects on neuronal survival signaling pathways. In this study, we investigated the effects of...

Increased Brain-Specific MiR-9 and MiR-124 in the Serum Exosomes of Acute Ischemic Stroke Patients.

PloS one

Ji Q, Ji Y, Peng J, Zhou X, Chen X, Zhao H, Xu T, Chen L, Xu Y.
PMID: 27661079
PLoS One. 2016 Sep 23;11(9):e0163645. doi: 10.1371/journal.pone.0163645. eCollection 2016.

The aims of this study were to examine the alternation in serum exosome concentrations and the levels of serum exosomal miR-9 and miR-124, two brain-specific miRNAs, in acute ischemic stroke (AIS) patients and to explore the predictive values of...

An insult-inducible vector system activated by hypoxia and oxidative stress for neuronal gene therapy.

Translational stroke research

Cheng MY, Lee IP, Jin M, Sun G, Zhao H, Steinberg GK, Sapolsky RM.
PMID: 21603078
Transl Stroke Res. 2011 Mar 01;2(1):92-100. doi: 10.1007/s12975-010-0060-2.

Gene therapy has demonstrated the protective potential of a variety of genes against stroke. However, conventional gene therapy vectors are limited due to the inability to temporally control their expression, which can sometimes lead to deleterious side effects. Thus,...

Lithium treatment reduces brain injury induced by focal ischemia with partial reperfusion and the protective mechanisms dispute the importance of akt activity.

Aging and disease

Takahashi T, Steinberg GK, Zhao H.
PMID: 22724081
Aging Dis. 2012 Jun;3(3):226-33. Epub 2012 Feb 08.

Lithium is a mood stabilizer shown to have neuroprotective effects against several chronic and acute neuronal injuries, including stroke. However, it is unknown whether lithium treatment protects against brain injury post-stroke in a rat model of permanent distal middle...

The Akt pathway is involved in rapid ischemic tolerance in focal ischemia in Rats.

Translational stroke research

Gao X, Zhang H, Steinberg G, Zhao H.
PMID: 21804899
Transl Stroke Res. 2010 Sep;1(3):202-9. doi: 10.1007/s12975-010-0017-5.

Although the protective mechanisms of delayed ischemic preconditioning have received extensive studies, few have addressed the mechanisms associated with rapid ischemic postconditioning. We investigated whether ischemic tolerance induced by rapid preconditioning is regulated by the Akt survival signaling pathway....

The underlying mechanisms involved in the protective effects of ischemic postconditioning.

Conditioning medicine

Xie R, Li J, Zhao H.
PMID: 29782624
Cond Med. 2018;1(2):73-79.

Cerebral ischemic postconditioning (PostC) refers to a series of brief ischemia and reperfusion (I/R) cycles applied at the onset of reperfusion following an ischemic event. PostC has been shown to have neuroprotective effects, and represents a promising clinical strategy...
