Summary: This study found that overexpression of SIK2 can alleviate neuronal damage and promote energy metabolism during cerebral ischemia-reperfusion, which is related to the regulation of the mTOR pathway and mitochondrial autophagy.

Summary: Delta opioids have tissue-protective properties and may relieve ischemic injury through transactivation of EGFR. Pre-treatment with a delta opioid receptor agonist improved neurologic deficits and reduced infarct volume in a rat model of ischemic stroke, effects that were blocked by EGFR and MMP inhibitors. Activation of EGFR, Akt, and ERK1/2 and upregulation of EGFR expression by the delta opioid agonist were inhibited by AG1478 and GM6001, suggesting an essential role of MMP-mediated transactivation of EGFR in the neuroprotective effects of delta opioids.

Summary: SPRED1 plays a regulatory role in the response of microglia to oxidative stress induced by cerebral ischemia. The expression of SPRED1 is downregulated in the ischemic brain, and hydrogen peroxide exerts a fluctuating regulatory effect on SPRED1 level in BV2 microglia, similar to its effect on NF-KB p65. SPRED1 overexpression alone does not mediate any regulatory effect, but in the presence of H2O2 induction, it leads to significant changes in various cellular phenomena.

Summary: Transient cerebral ischemia followed by reperfusion in an infarcted brain results in predictable morphological changes in neuronal and non-neuronal cells. Accurately delineating the cerebral infarct is challenging, but using a macroscopic histological approach can lead to faster and more reliable preclinical research results. The study found that the MAP2 staining method can reliably identify the ischemic area macroscopically in cryo-preserved and paraffin-embedded brain sections, regardless of immersion-fixed or perfusion-fixed brains.

Summary: AG490 acts as a JAK antagonist showing both anti-apoptotic and neuroprotective effects in cerebral ischemia/reperfusion injury. It achieves the anti-apoptotic effect through regulating the JAK-STAT pathway and enhancing the expression of neurotrophins.

Summary: The study demonstrates that intranasal administration of Nestorone can effectively promote recovery after stroke and is effective in male mice. Furthermore, the research findings also indicate that neural PR plays a key role in the cerebroprotective effects of Nestorone.

Summary: This study found that there was overexpression of miRNAs in the acute stage of subarachnoid hemorrhage in comparison with non-SAH controls. Specific miRNAs were also found to be differentially expressed based on clinical severity and the development of delayed cerebral ischemia and midterm functional outcomes. These observations suggest the potential utility of miRNAs as prognostic and diagnostic biomarkers in SAH patients.

Summary: The activation of GABA(B) receptors with baclofen provides neuroprotection against excitotoxic death in cerebral ischemia. Sustained activation stabilizes receptor expression and reduces downregulation under excitotoxic conditions, preserving GABA(B) receptor-mediated inhibition. This restoration of GABA(B) receptors enhances neuronal survival and function, making them promising targets for neuroprotection in acute cerebral ischemia.

Summary: This study conducted comprehensive circulating miRNA profiling in patients with ischemic stroke and identified a panel of miRNAs with potential diagnostic and prognostic significance. A multivariate classifier based on this miRNA panel showed high sensitivity and specificity in differentiating between stroke patients and healthy controls, and it outperformed other available biomarkers.

Summary: This study evaluated the impact of prolonged exposure to room temperature on RNA quality in non-diseased breast tissue. The results showed that up to 190 minutes after excision, higher RNA Integrity Numbers (RINs) were obtained. Further exposure of up to 180 minutes had no significant effect on RIN values. This study strengthens the rationale for assessing RIN and specific gene transcript levels as an objective method for determining RNA suitability for research purposes.

Summary: Among cerebral venous thrombosis (CVT) patients, those with venous infarction have more severe clinical presentations and worse outcomes. Identifying biomarkers associated with venous infarction in CVT may help understand the pathogenesis and provide potentially useful therapeutic markers. Serum hs-CRP levels were significantly higher in acute/subacute CVT patients with venous infarction than those without, and hs-CRP was positively correlated with the NIHSS on admission. Hs-CRP might serve as a biomarker reflecting the clinical severity of CVT in the acute/subacute stages.

Summary: The study identified alterations in the m6A modification profile in cerebral ischemia-reperfusion injury model rats, leading to differential gene expression associated with inflammation and neuronal pathways. Among m6A regulators, FTO was specifically downregulated in neurons after MCAO/R, providing new insights into the mechanisms of cerebral ischemia-reperfusion injury.

Summary: Hepatic ischemia-reperfusion injury (IRI) is a major factor in early allograft dysfunction in liver transplantation. miRNAs have been shown to play a crucial role in regulating gene expression and can be manipulated to attenuate liver damage and improve patient outcomes.
