A novel self-assemble peptide drug design of AKT1 for anaplastic thyroid cancer therapy.

Anaplastic thyroid cancer (ATC) is an undifferentiated subtype of thyroid cancer with a markedly poor survival prognosis, estimated to occur 3-5 months after diagnosis. Akt activation is reportedly involved in tumorigenesis during ATC and represents a new therapeutic target. Based on the Akt1/bisubstrate complex structure and artificial intelligence-assisted peptide drug screening, we designed a self-assemble Akt1-targeting peptide drug exhibiting a 0.

Glutaredoxin 1 protects neurons from oxygen-glucose deprivation/reoxygenation (OGD/R)-induced apoptosis and oxidative stress via the modulation of GSK-3β/Nrf2 signaling.

Increasing evidence has indicated that glutaredoxin 1 (GRX1) is a potent antioxidant protein that promotes cell survival under conditions of oxidative stress. Oxidative stress-induced neuronal injury contributes to cerebral ischemia/reperfusion injury. However, the role of GRX1-mediated antioxidant defense against neuronal damage during cerebral ischemia/reperfusion injury has not been thoroughly investigated.

Alzheimer's Disease Determination by a Dual Probe on Gold Nanourchins and Nanohorn Hybrids.

Background: Alzheimer's disease (AD) is a neurodegenerative chronic disorder that causes dementia and problems in thinking, cognitive impairment and behavioral changes. Amyloid-beta (Aβ) is a peptide involved in AD progression, and a high level of Aβ is highly correlated with severe AD. Identifying and quantifying Aβ levels helps in the early treatment of AD and reduces the factors associated with AD.

Tectorigenin attenuates the OGD/R-induced HT-22 cell damage through regulation of the PI3K/AKT and the PPARγ/NF-κB pathways.

Tectorigenin (TEC) is an effective compound that derived from many plants, such as . Evidence suggested that TEC has anti-tumor, anti-oxidant activity, anti-bacterial and anti-inflammatory effects. In addition, there has some evidence indicated that TEC is a potential anti-stroke compound; however, its specific roles and associated mechanism have not yet been elucidated.

17β-Estradiol Protects Neural Stem/Progenitor Cells Against Ketamine-Induced Injury Through Estrogen Receptor β Pathway.

Ketamine inhibits neural stem/progenitor cell (NSPC) proliferation and disrupts normal neurogenesis in the developing brain. 17β-Estradiol alleviates neurogenesis damage and enhances behavioral performance after ketamine administration. However, the receptor pathway of 17β-estradiol that protects NSPCs from ketamine-induced injury remains unknown.

Senescence marker protein 30 confers neuroprotection in oxygen-glucose deprivation/reoxygenation-injured neurons through modulation of Keap1/Nrf2 signaling: Role of SMP30 in OGD/R-induced neuronal injury.

Senescence marker protein 30 (SMP30) is a senescence marker molecule and identified as a calcium regulatory protein. Currently, SMP30 has emerged as a cytoprotective protein in a wide range of cell types. However, the role of SMP30 in regulating neuronal survival during cerebral ischemia/reperfusion injury remains unclear.

Attenuation of Acute Intracerebral Hemorrhage-Induced Microglial Activation and Neuronal Death Mediated by the Blockade of Metabotropic Glutamate Receptor 5 In Vivo.

The activation of microglia in response to intracerebral hemorrhagic stroke is one of the principal components of the progression of this disease. It results in the formation of pro-inflammatory cytokines that lead to neuronal death, a structural deterioration that, in turn interferes with functional recovery. Metabotropic glutamate receptor 5 (mGluR5) is highly expressed in reactive microglia and is involved in the pathological processes of brain disorders, but its role in intracerebral hemorrhage (ICH) remains unknown.

Dexmedetomidine Alleviates Neurogenesis Damage Following Neonatal Midazolam Exposure in Rats through JNK and P38 MAPK Pathways.

Midazolam, a widely used anesthetic, inhibits proliferation of neural stem cells (NSCs) and induces neuroapoptosis in neonates. Dexmedetomidine, an effective auxiliary medicine in clinical anesthesia, protects the developing brain against volatile anesthetic-induced neuroapoptosis. Whether dexmedetomidine protects against neurogenesis damage induced by midazolam remains unknown.

Trigonelline protects hippocampal neurons from oxygen-glucose deprivation-induced injury through activating the PI3K/Akt pathway.

Trigonelline is a plant alkaloid that has generated interest for its neuroprotective roles in brain pathology. However, the protective effect of trigonelline on cerebral ischemia/reperfusion (I/R) injury and the potential mechanism have not been fully evaluated. Our results showed that trigonelline pretreatment ameliorated oxygen-glucose deprivation/reperfusion (OGD/R)-induced hippocampal neurons injury.

Dexmedetomidine Inhibits Neuroinflammation by Altering Microglial M1/M2 Polarization Through MAPK/ERK Pathway.

Neuroinflammation is critical in the pathogenesis of neurological diseases. Microglial pro-inflammatory (M1) and anti-inflammatory (M2) status determines the outcome of neuroinflammation. Dexmedetomidine exerts anti-inflammatory effects in many neurological conditions.

Efficacy of metoclopramide for the treatment of acute migraine.

Background: In this study, we will assess the efficacy and safety of metoclopramide for the treatment of acute migraine (AM).

Methods: We will comprehensively search Cochrane Library, PUMBED, EMBASE, Google Scholar, Web of Science, Allied and Complementary Medicine Database, Chinese Biomedical Literature Database, and China National Knowledge Infrastructure from the inception to July 1, 2019 to identify any eligible studies. Only randomized controlled trials will be considered for inclusion.

Edaravone protects primary-cultured rat cortical neurons from ketamine-induced apoptosis via reducing oxidative stress and activating PI3K/Akt signal pathway.

Ketamine caused neuroapoptosis in the development of rat brain, in which oxidative stress play an important role. Edaravone (3-methyl-1-phenyl-2-pyrazolin-5-one), a free radical scavenger, exerts neuroprotective effects in many neurological disease models. Here we investigated whether edaravone protects primary-cultured neurons against ketamine-induced apoptosis and its potential mechanism.

Overexpression of TRIM26 suppresses the proliferation, metastasis, and glycolysis in papillary thyroid carcinoma cells.

Papillary thyroid carcinoma (PTC) is the common subtype of thyroid cancer, which is a common endocrine malignancy. Tripartite motif 26 (TRIM26) has been found to act as a tumor suppressor in several cancers. However, the functional roles of TRIM26 in PTC remain unknown.

Differential expression of endocannabinoid system-related genes in the dorsal hippocampus following expression and reinstatement of morphine conditioned place preference in mice.

The endocannabinoid signaling plays a critical role in mediating rewarding effects to morphine. The relative stability for the expression and reinstatement of morphine conditioned place preference (CPP) suggests the involvement of differential neuroadaptations in learned associations between environmental cues and morphine. Changes in gene expression in hippocampus through the endogenous cannabinoid system (eCB) may accompany and mediate the development of such neuroadaptations to repeated morphine stimulation.

Combined treatment with GH, insulin, and indomethacin alleviates cancer cachexia in a mouse model.

Cancer-induced cachexia involves weight loss, catabolic activity, and inflammation. We have evaluated the effects of various treatments (GH, insulin (INS), indomethacin (IND), and all possible combinations) on cancer cachexia in a mouse model. BALB/c mice that were implanted with colon-26 adenocarcinoma developed cachexia in 9 days.
