Changes in insular cortex metabolites in patients with obstructive sleep apnea syndrome.

The aim of this study was to investigate the changes in insular cortex metabolites and the correlation with clinical manifestations in patients with obstructive sleep apnea syndrome (OSA). Lateral insular metabolite levels were measured and relevant ratios were calculated in OSA patients and healthy individuals, including N-acetyl aspartate/creatine (NAA/Cr), choline/creatine (Cho/Cr), inositol/creatine (Ins/Cr), glutamate compound/creatine (Glx/Cr), N-acetyl aspartate/choline (NAA/Cho), and lactic acid (Lac). Participants' scores on the Hamilton Anxiety Scale (HAMA), the Hamilton Depression Scale (HAMD), the Pittsburgh Sleep Quality Index (PSQI), and the Epworth Sleepiness Scale (ESS) were also evaluated.

Expression Levels of Interferon Regulatory Factor 5 (IRF5) and Related Inflammatory Cytokines Associated with Severity, Prognosis, and Causative Pathogen in Patients with Community-Acquired Pneumonia.

BACKGROUND Community-acquired pneumonia (CAP) is a common disease with significant morbidity and mortality. Interferon regulatory factor 5 (IRF5), which induces type I interferons (IFNs) and cytokines such as interleukin (IL)-6, tumor necrosis factor (TNF)-α, IL-10, and interferon gamma-induced protein (IP)10, is a key transcription factor involved in controlling the expression of proinflammatory cytokines and responses to infection. Here, we carefully investigated the role of IRF5 in regulating immune responses to CAP.

Of 21 cases were type I deviation, of 12 cases were C-shaped deviation,and of 6 cases were S-shaped deviation.

Effects of Habenular Stimulation Frequencies on Obstructive Sleep Apnea Induced by Stimulation of Insular Cortex.

Objective: To investigate the effects of high-frequency stimulation of the habenula (Hb) on obstructive sleep apnea (OSA) induced by stimulation of the insular cortex . After OSA was induced by stimulating the insular cortex (Ic) with concentric stimulating electrodes at 100 Hz in rats, the Hb was stimulated at different frequencies (50 Hz, 120 Hz, 130 Hz, and 280 Hz). The changes of apnea events and electromyography (EMG) of the genioglossus were compared before and after stimulation of the Hb.

Regulation of Integrated Stress Response Sensitizes U87MG Glioblastoma Cells to Temozolomide Through the Mitochondrial Apoptosis Pathway.

Glioblastomas are the most frequently diagnosed and worst primary malignancy of the central nervous system, with very poor prognosis. The first-line antiglioma drug temozolomide shows decreasing therapeutic efficacy as treatment progresses. As the integrated stress response (ISR) may be a resistance factor and severe stress might transform the protective effect of the ISR into a damage effect, pharmacological regulation of ISR may be an effective way to sensitize glioma to temozolomide.

Functional Evaluation of ZNF350 Missense Genetic Variants Associated with Breast Cancer Susceptibility.

ZNF350, a BRCA1-interacting protein, could mediate BRCA1-induced sequence-specific transcriptional repression of several genes, including GADD45α. As a potential breast cancer susceptibility gene, single nucleotide polymorphisms (SNPs), especially missense SNPs, may influence the transcriptional repression of its target tumor suppressor genes and individuals' breast cancer risk. Using the gene-based haplotype-tagging SNPs strategy, we evaluated the association between six ZNF350 polymorphisms and breast cancer risk in a case-control set from a northern Chinese population.

Nimotuzumab enhances the sensitivity of non-small cell lung cancer cells to tumor necrosis factor-α by inhibiting the nuclear factor-кB signaling pathway.

Non-small cell lung cancer (NSCLC) accounts for ~85% of lung cancer cases worldwide. Current guidelines recommend the use of epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors for patients with NSCLC. The EGF/EGFR signaling pathway has been demonstrated to activate nuclear factor (NF)-κB, which may inhibit tumor necrosis factor (TNF)-α induced cell apoptosis.

HDAC6 inhibition induces glioma stem cells differentiation and enhances cellular radiation sensitivity through the SHH/Gli1 signaling pathway.

The existence of small numbers of stem-like cells, called glioma stem cells (GSCs), in human glioblastoma multiforme (GBM) is responsible for recurrence due to resistance to radiotherapy and chemotherapy. Inhibition of histone deacetylase 6 (HDAC6) enhanced radiosensitivity of cancer cells. However, the effect of inhibiting HDAC6 on stemness and radioresistance of GSCs and its molecular mechanism are largely unknown.

Cerebral venous collaterals: A new fort for fighting ischemic stroke?

Stroke therapy has entered a new era highlighted by the use of endovascular therapy in addition to intravenous thrombolysis. However, the efficacy of current therapeutic regimens might be reduced by their associated adverse events. For example, over-reperfusion and futile recanalization may lead to large infarct, brain swelling, hemorrhagic complication and neurological deterioration.

Long noncoding RNA CCAT1 functions as a ceRNA to antagonize the effect of miR-410 on the down-regulation of ITPKB in human HCT-116 and HCT-8 cells.

Colorectal cancer is one of the most common malignancies, which has seriously affected people's health. Abnormal expression of long non-coding RNAs and microRNAs are closely related to the process of occurrence, development, invasion and metastasis of colorectal cancer. However, the effect of lnc on human HCT-116/HCT-8 cells and its potential mechanism were investigated.

[Advances in the Transformation to Small Cell Lung Cancer from Non-small Cell Lung Cancer Following Acquired Drug-resistance to EGFR Tyrosine Kinase Inhibitors].

The use of epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) in the treatment of sensitive EGFR mutation in non-small cell lung cancer (NSCLC) has been proved significant curative effect. However, the acquisition of the drug resistance to EGFR-TKIs is almost inevitable, and common drug resistance mechanisms include T790M mutation, cMET amplification, etc. One of the rare resistance mechanisms of EGFR-TKIs is the transformation from NSCLC into small cell lung cancer (SCLC), which account for about 3%-15%.

The effects of Curcumin on HCT-116 cells proliferation and apoptosis via the miR-491/PEG10 pathway.

Paternally expressed gene-10 (PEG10) could participate in several carcinomas and might be regulated by miR-491. To now, miR-491 was found to play an important role in the sensitivity and mechanism of drug usage in the treatment of colorectal cancer, and drug resistance is a key factor to affect the disease healing. In this study, miR-491, PEG10, Wnt1, and β-catenin expression levels and their correlation with colorectal cancer were assessed in cancer tissues and adjacent parts.

Phosphorylated E2F1 is stabilized by nuclear USP11 to drive Peg10 gene expression and activate lung epithelial cells.

Phosphorylation affects ubiquitination, stability, and activity of transcriptional factors, thus regulating various cellular functions. E2F transcriptional factor 1 (E2F1) regulates paternally expressed imprinted gene 10 (Peg10) expression, thereby promoting cell proliferation. However, the effect of E2F1 stability on Peg10 expression and the molecular regulation of E2F1 stability by its phosphorylation have not been well demonstrated.

The deubiquitinating enzyme USP48 stabilizes TRAF2 and reduces E-cadherin-mediated adherens junctions.

The tumor necrosis factor receptor-associated factor 2 (TRAF2) is a second messenger adaptor protein that plays an essential role in propagating TNF-α-mediated signaling pathways. Modulation of TRAF2 activity by ubiquitination is well studied; however, the deubiquitinating enzyme (DUB), which regulates TRAF2 stability, has not been identified. Here we reveal USP48 as the first identified DUB to deubiquitinate and stabilize TRAF2 in epithelial cells.
