PPP1R12C Promotes Atrial Hypocontractility in Atrial Fibrillation
CONCLUSIONS: Patients with AF exhibit increased levels of PPP1R12C protein compared with controls. PPP1R12C overexpression in mice increases PP1c targeting to MLC2a and causes MLC2a dephosphorylation, which reduces atrial contractility and increases AF inducibility. These findings suggest that PP1 regulation of sarcomere function at MLC2a is a key determinant of atrial contractility in AF.PMID:37737016 | DOI:10.1161/CIRCRESAHA.123.322516

CircNCOA4 knockdown attenuates OGD-induced neuron injury through miR-338-5p/PDE4B axis
Exp Brain Res. 2023 Sep 16. doi: 10.1007/s00221-023-06702-w. Online ahead of print.ABSTRACTCircular RNAs (circRNAs) have been revealed to be involved in the pathology of acute ischemic stroke (AIS). Herein, we aimed to study the role and mechanism of circNCOA4 in ischemic stroke. The neuron-like cell line SK-N-SH of the experiment group was cultured in oxygen-glucose deprivation (OGD) condition. Cell viability and apoptosis were evaluated by cell counting kit-8 and flow cytometry. The oxidative damage and endoplasmic reticulum stress (ERS) were analyzed by measuring the production of reactive oxygen species (ROS), malondia...

Treatment of Stroke at a Delayed Timepoint with a Repurposed Drug Targeting Sigma 1 Receptors
In this study, we hypothesized that oral oxeladin citrate would stimulate BDNF secretion and improve stroke outcomes when administered to male rats starting 48 h after transient middle cerebral artery occlusion. Oxeladin did not alter blood clotting and crossed the blood brain barrier within 30 min of oral administration. Rats underwent 90 min of transient middle cerebral artery occlusion. Forty-eight hours later rats began receiving daily oxeladin (135 mg/kg) for 11 days. Oxeladin significantly improved neurological function on days 3, 7, and 14 following MCAO. Infarct size was not altered by a single dose, but the final ...

Linkage of blood cell division cycle 42 with T helper cells, and their correlation with anxiety, depression, and cognitive impairment in stroke patients
This study aimed to assess the correlation between blood CDC42 and Th cells, and their association with mental issues in stroke patients. Peripheral blood samples were obtained from 264 stroke patients and 50 controls. Then, serum CDC42 was measured by enzyme-linked immunosorbent assay, and Th1, Th2, and Th17 cells were detected by flow cytometry. Hospital Anxiety and Depression Scale (HADS) and Mini Mental State Examination (MMSE) were applied to patients. CDC42 was decreased (P<0.001), Th1 (P=0.013) and Th17 (P<0.001) cells were elevated, while Th2 cells (P=0.108) showed no difference in stroke patients compared to...

Tranexamic acid in a mouse model of cerebral amyloid angiopathy: setting the stage for a novel stroke treatment approach
CONCLUSION: Long-term TXA treatment does not alter brain Aβ levels or impact neurologic behavior in mice predisposed to amyloid deposition and had minor effects on the levels of inflammatory mediators. This finding supports the safety of TXA and lays the foundation for TXA as a novel treatment to reduce sICH in patients with CAA.PMID:37694270 | PMC:PMC10483050 | DOI:10.1016/j.rpth.2023.102166

Neurological manifestations of SARS-CoV-2: complexity, mechanism and associated disorders
CONCLUSIONS: SARS-CoV-2 can lead to neurological complications, such as cerebrovascular manifestations, motor movement complications, and cognitive decline. COVID-19 infection can result in cerebrovascular symptoms and diseases, such as strokes and thrombosis. The virus can affect the neural system, disrupt cognitive function and cause neurological disorders. To combat the epidemic, it is crucial to repurpose drugs currently in use quickly and develop novel therapeutics.PMID:37649125 | PMC:PMC10469568 | DOI:10.1186/s40001-023-01293-2

The Association of the Neutrophil-to-Lymphocyte Ratio, Platelet-to-Lymphocyte Ratio, Lymphocyte-to-Monocyte Ratio and Systemic Inflammation Response Index with Short-Term Functional Outcome in Patients with Acute Ischemic Stroke
CONCLUSION: NLR, PLR, LMR, and SIRI were associated with functional outcome at discharge in AIS patients. NLR, LMR and SIRI were related to hospitalization days in patients with AIS.PMID:37641703 | PMC:PMC10460585 | DOI:10.2147/JIR.S418106

Increased neuropil antibody prevalence in COVID-19 patients with acute ischemic stroke
CONCLUSION: Our results confirm the presence of neuropil antibodies in patients with COVID-19 infection and identify a putative antibody-driven association between AIS and COVID-19. The antigenic targets and potential pathogenic action of these antibodies need to be further explored.PMID:37634189 | DOI:10.1080/01616412.2023.2252282

Activation of endothelial TRPM2 exacerbates blood-brain barrier degradation in ischemic stroke
CONCLUSIONS: In conclusion, our data reveals a novel molecular mechanism in which TRPM2 and CD36 promote the activation of each other, which exacerbates endothelial dysfunction during ischemic stroke. Our study suggests that TRPM2 in endothelial cells is a promising target for developing more effective and safer therapies for ischemic stroke.PMID:37595268 | DOI:10.1093/cvr/cvad126

Neurochem Res. 2023 Jul 28. doi: 10.1007/s11064-023-03999-5. Online ahead of print.ABSTRACTStroke is an acute cerebrovascular disease resulting from either obstruction or rupture of a blood vessel in the brain. Oxidative stress (OS), referred to a status where cellular oxidative capacities overwhelm antioxidative defenses, is involved in the pathophysiology of stroke. The bibliometric analysis and in-depth review aim to depict the research trend of OS in stroke. Relevant scientific publications were acquired from the Web of Science Core Collection database. Scientific landscape of OS in stroke was illustrated by general qu...

The novel function of bexarotene for neurological diseases
Ageing Res Rev. 2023 Jul 24:102021. doi: 10.1016/j.arr.2023.102021. Online ahead of print.ABSTRACTBexarotene, a retinoid X receptor (RXR) agonist, is approved by FDA to treat cutaneous T-cell lymphoma. However, it has also demonstrated promising therapeutic potential for neurological diseases such as stroke, traumatic brain injury, Parkinson's disease, and particularly Alzheimer's disease(AD). In AD, bexarotene inhibits the production and aggregation of amyloid β (Aβ), activates Liver X Receptor/RXR heterodimers to increase lipidated apolipoprotein E to remove Aβ, mitigates the negative impact of Aβ, regulates neuroinf...
