LncRNA sponges miRNA-221 to promote neurons apoptosis by up-regulated PUMA under hypoxia condition.

: Long noncoding RNAs (lncRNAs) play substantial roles in cerebral ischemia. Growth arrest-specific 5 (GAS5) was reported to be involved in stroke. In the present study, we aimed to investigate the roles of GAS5 in cerebral condition and unveil the underlying mechanism.

Biochanin A Reduces Inflammatory Injury and Neuronal Apoptosis following Subarachnoid Hemorrhage via Suppression of the TLRs/TIRAP/MyD88/NF-B Pathway.

Inflammatory injury and neuronal apoptosis participate in the period of early brain injury (EBI) after subarachnoid hemorrhage (SAH). Suppression of inflammation has recently been shown to reduce neuronal death and neurobehavioral dysfunction post SAH. Biochanin A (BCA), a natural bioactive isoflavonoid, has been confirmed to emerge the anti-inflammatory pharmacological function.

Roles of Pannexin-1 Channels in Inflammatory Response through the TLRs/NF-Kappa B Signaling Pathway Following Experimental Subarachnoid Hemorrhage in Rats.

Accumulating evidence suggests that neuroinflammation plays a critical role in early brain injury after subarachnoid hemorrhage (SAH). Pannexin-1 channels, as a member of gap junction proteins located on the plasma membrane, releases ATP, ions, second messengers, neurotransmitters, and molecules up to 1 kD into the extracellular space, when activated. Previous studies identified that the opening of Pannexin-1 channels is essential for cellular migration, apoptosis and especially inflammation, but its effects on inflammatory response in SAH model have not been explored yet.

Fisetin alleviates early brain injury following experimental subarachnoid hemorrhage in rats possibly by suppressing TLR 4/NF-κB signaling pathway.

Early brain injury (EBI) determines the unfavorable outcomes after subarachnoid hemorrhage (SAH). Fisetin, a natural flavonoid, has anti-inflammatory and neuroprotection properties in several brain injury models, but the role of fisetin on EBI following SAH remains unknown. Our study aimed to explore the effects of fisetin on EBI after SAH in rats.

Expression and Cell Distribution of SENP3 in Brain Tissue After Traumatic Brain Injury in Mice: A Pilot Study.

SUMO-specific proteases 3 (SENP3) is a member of the small ubiquitin-like modifier-specific protease family and deconjugates SUMO2/3 from protein substrates. To date, the expression and function of SENP3 in traumatic brain injury (TBI) are unclear. The present study examined dynamic changes in SENP3 expression in the cerebral cortex and in its cellular localization, using an acute TBI model in adult mice.

Expression of Cytoplasmic Gelsolin in Rat Brain After Experimental Subarachnoid Hemorrhage.

Convincing evidence indicates that apoptosis contributes to the unfavorable prognosis of subarachnoid hemorrhage (SAH), a significant cause of morbidity and case fatality throughout the world. Gelsolin (GSN) is a Ca(2+)-dependent actin filament severing, capping, and nucleating protein, as well as multifunctional regulator of cell structure and metabolism, including apoptosis. In the present study, we intended to investigate the expression pattern and cell distribution of GSN in rat brain after experimental SAH.

Constriction and dysfunction of pial arterioles after regional hemorrhage in the subarachnoid space.

Increasing evidence indicates that poor outcomes after brain hemorrhage, especially after subarachnoid hemorrhage (SAH), can be attributed largely to dysfunction of the cerebral microcirculation. However, the cause of this dysfunction remains unclear. Here, we investigated changes in the cerebral microcirculation after regional hemorrhage in the subarachnoid space using the closed cranial window technique in mice.

Baincalein alleviates early brain injury after experimental subarachnoid hemorrhage in rats: possible involvement of TLR4/NF-κB-mediated inflammatory pathway.

Early brain injury (EBI) following subarachnoid hemorrhage (SAH) largely contributes to unfavorable outcomes. Hence, effective therapeutic strategies targeting on EBI have recently become a major goal in the treatment of SAH patients. Baicalein is a flavonoid that has been shown to offer neuroprotection in kinds of brain injury models.

Ghrelin alleviates early brain injury after subarachnoid hemorrhage via the PI3K/Akt signaling pathway.

Early brain injury (EBI) plays a key role in the pathogenesis of subarachnoid hemorrhage (SAH). Although the neuroprotective effects of ghrelin have been demonstrated in several studies, whether ghrelin reduces EBI after SAH remains unknown. In this study, we hypothesized that treatment with ghrelin would attenuate EBI after SAH, and that this protection would be mediated, at least in part, by activation of the PI3K/Akt signaling pathway.

Astaxanthin offers neuroprotection and reduces neuroinflammation in experimental subarachnoid hemorrhage.

Background: Neuroinflammation has been proven to play a crucial role in early brain injury pathogenesis and represents a target for treatment of subarachnoid hemorrhage (SAH). Astaxanthin (ATX), a dietary carotenoid, has been shown to have powerful anti-inflammation property in various models of tissue injury. However, the potential effects of ATX on neuroinflammation in SAH remain uninvestigated.

Haplotype analysis of single nucleotide polymorphisms in anti-Müllerian hormone gene in Chinese PCOS women.

Purpose: Anti-Müllerian hormone (AMH) inhibits FSH-stimulated follicle growth and aromatase activity. The three fold higher serum AMH in PCOS patients may account for the increased number of small follicles and androgen level. We attempted to determine whether polymorphisms in AMH gene were associated with PCOS in Chinese han population.

Microsatellite polymorphism in the fibrillin 3 gene and susceptibility to PCOS: a case-control study and meta-analysis.

The D19S884 marker at the fibrillin 3 gene has been analysed as a candidate location for polycystic ovary syndrome (PCOS) mainly in Caucasian descendants. A case-control study was performed with 272 PCOS women and 271 controls to test the hypothesis that variants in the D19S884 marker increase susceptibility to PCOS in Chinese women and a meta-analysis was undertaken to clarify whether there is an allele consistently contributing to the susceptibility. The association analysis showed that PCOS women were significantly different from controls in the distribution of D19S884 allele frequencies.
