Curcumin triggers the Wnt/β-catenin pathway and shields neurons from injury caused by intermittent hypoxia.

The objective of this study was to explore the molecular basis through which Curcumin (Cur) mitigates neuronal damage caused by obstructive sleep apnea (OSA). HT22 was used to simulate intermittent hypoxia (IH) injury and explore the effect of Cur on these cells. We evaluated the cell viability, cytotoxicity, apoptosis, proliferation, and Wnt/β-catenin (WβC) pathway.

Curcumin activates the Wnt/β-catenin signaling pathway to alleviate hippocampal neurogenesis abnormalities caused by intermittent hypoxia: A study based on network pharmacology and experimental verification.

The purpose of this work was to investigate how curcumin (Cur) might enhance cognitive function and to gain a better understanding of the molecular mechanisms behind Cur's impacts on neurogenesis deficits brought on by intermittent hypoxia (IH). Using network pharmacology, we explored possible targets for Cur's obstructive sleep apnea (OSA) therapy. We established an IH model using C57BL/6 mice and c17.

Burdened breaths: The influence of depression on obstructive sleep apnea.

Depression and metabolic syndrome could exacerbate the risks of the other, leading to a series of severe coexisting conditions. One notable comorbidity that must be mentioned is obstructive sleep apnea (OSA). Current studies suggested that depression increases susceptibility to OSA.

Beyond surgery: Overcoming postoperative depression in cancer patients.

Depression is a common occurrence among cancer patients, and it significantly impacts their clinical outcomes and quality of life, with a high incidence during anti-tumor treatment or after surgery. The association between surgery and depression is the result of the interaction of various factors, including physiological, psychological, and social factors, all of which are intertwined and make patients susceptible to depression after surgical treatment. Postoperative depression has a significant negative impact on many aspects of cancer patients, and it requires timely identification and intervention to improve the overall outcome.

Obstructive sleep apnea affects cognition: dual effects of intermittent hypoxia on neurons.

Obstructive sleep apnea (OSA) is a common respiratory disorder. Multiple organs, especially the central nervous system (CNS), are damaged, and dysfunctional when intermittent hypoxia (IH) occurs during sleep for a long time. The quality of life of individuals with OSA is significantly impacted by cognitive decline, which also escalates the financial strain on their families.

Pathophysiological mechanisms and therapeutic approaches in obstructive sleep apnea syndrome.

Obstructive sleep apnea syndrome (OSAS) is a common breathing disorder in sleep in which the airways narrow or collapse during sleep, causing obstructive sleep apnea. The prevalence of OSAS continues to rise worldwide, particularly in middle-aged and elderly individuals. The mechanism of upper airway collapse is incompletely understood but is associated with several factors, including obesity, craniofacial changes, altered muscle function in the upper airway, pharyngeal neuropathy, and fluid shifts to the neck.

Obstructive sleep apnea hypopnea syndrome in ancient traditional Chinese medicine.

In western medicine, obstructive sleep apnea hypopnea syndrome (OSAHS) is an increasingly serious public health hazard, which is exacerbated by the obesity epidemic and an aging population. Ancient medical literature of traditional Chinese medicine (TCM) also recorded OSAHS-like symptoms but described the disease from a completely distinct theoretical perspective. The earliest records of snoring in ancient China can be traced back 2500 years.

Neuroprotective role of fucoxanthin against cerebral ischemic/reperfusion injury through activation of Nrf2/HO-1 signaling.

In the present study, an attempt was made to determine whether administration of fucoxanthin could attenuate cerebral ischemic/reperfusion (I/R) injury and its possible mechanisms using an in vivo middle cerebral artery occlusion (MCAO) model and an in vitro oxygen-glucose deprivation and reoxygenation (OGD/R) model. Fucoxanthin was intragastrically administrated in different doses (30 mg/kg, 60 mg/kg, and 90 mg/kg, respectively) to the rats 1 h before MCAO induction. The neurological function, infarct area and brain water content of rats were then evaluated.

MiR-138/SIRT1 axis is implicated in impaired learning and memory abilities of cerebral ischemia/reperfusion injured rats.

The present study aimed to explore whether deregulated miR-138 is implicated in cerebral I/R injury-impaired learning and memory abilities. Rats were subjected to bilateral common carotid occlusion followed by reperfusion to induce cerebral I/R injury. A model of oxygen-glucose deprivation and reperfusion (OGD/R) was conducted to mimic cerebral I/R conditions in vitro.

The CNPY2 enhances epithelial-mesenchymal transition via activating the AKT/GSK3β pathway in non-small cell lung cancer.

The survival of non-small cell lung cancer (NSCLC) is poor due to high metastasis, and the indispensable step of metastasis includes epithelial-mesenchymal transition (EMT). In the study, by analyzing the dataset of the Cancer Genome Atlas (TCGA), we found that the expression of Canopy homolog 2 (CNPY2) is increased both in adenocarcinoma and squamous cell carcinoma, which is further confirmed in NSCLC tissues. Not only that, there is a negative correlation between CNPY2 and E-cadherin expression at mRNA level.

Mesenchymal Stem Cells Expressing eNOS and a Cav1 Mutant Inhibit Vascular Smooth Muscle Cell Proliferation in a Rat Model of Pulmonary Hypertension.

Background: This study aimed to investigate the effect of bone marrow derived mesenchymal stem cells (rBMSCs) transduced with lentiviral vectors expressing endothelial nitric oxide synthase (eNOS) and/or a mutant caveolin-1(F92A-Cav1), on the pulmonary haemodynamics and structure in a rat model of pulmonary arterial hypertension (PAH).

Methods: Pulmonary arterial hypertension was induced with monocrotaline (MCT) in 60 adult male Wistar rats prior to delivery of lentiviral vector transduced rBMSCs expressing Cav1, eNOS and/or F92A-Cav1. Changes in pulmonary haemodynamics, right ventricular hypertrophy index (RVHI), and serum nitric oxide (NO) were evaluated.

Gene expression profiling of common signal transduction pathways affected by rBMSCs/F92A-Cav1 in the lungs of rat with pulmonary arterial hypertension.

Background: Pulmonary arterial hypertension (PAH) is associated with sustained vasoconstriction, inflammation and suppressed apoptosis of smooth muscle cells. Our previous studies have found that rat bone marrow-derived mesenchymal stem cells (rBMSCs) transduced with a mutant caveolin-1(F92A-Cav1) could enhance endothelial nitric oxide synthase (eNOS) activity and improve pulmonary vascular remodeling, but the potential mechanism is not yet fully explored. The present study was to investigate the gene expression profile upon rBMSCs/F92A-Cav1delivered to PAH rat to evaluate the role of F92A-Cav1 in its regulation.
