A meta-analysis of caspase-8 -652 6N del polymorphism and digestive tract cancer risk.

Caspase-8 (CASP8) is one key regulator of apoptosis of T lymphocytes and is encoded by the CASP8 gene. It has been reported that the six-nucleotide deletion polymorphism (-652 6N del) of the CASP8 gene had effect on some cancer risk. Few studies explored the association between CASP8 gene polymorphism and digestive tract cancer risk.

Lipopolysaccharide aggravated DOI-induced Tourette syndrome: elaboration for recurrence of Tourette syndrome.

Tourette syndrome (TS) is a neurological disorder characterized by highest familial recurrence rate among neuropsychiatric diseases with complicated inheritance. Recurrence of Tourette syndrome was frequently observed in clinical. Unexpectedly, the mechanism of recurrence of Tourette syndrome was failure to elucidate.

LY294002, a PI3K inhibitor, attenuates Tourette syndrome in rats.

The present study was designed to investigate the effects of LY294002 on Tourette syndrome (TS) in rats. TS model was induced in rats by DOI (the selective 5-HT2A/2C agonist 1- (2, 5- dimethoxy -4 - iodophenyl) -2- aminopropane). Behavior was assessed by stereotypic score and autonomic activity.

Protective effect of pilose antler peptide on carbon tetrachloride-induced hepatotoxicity in mice.

The present study was designed to investigate the beneficial effects of pilose antler peptide (PAP) against carbon tetrachloride (CCl) hepatotoxicity in mice, and explore the underlying mechanisms. In our results, animals were treated with either CCl and/or PAP for six consecutive weeks. The levels of inflammatory cytokines in serum and liver, hepatotoxicity markers in serum and histopathological evaluation were determined.

Anti-inflammatory Role of Pilose Antler Peptide in LPS-Induced Lung Injury.

The present study was designed to investigate the effects of pilose antler peptide (PAP) on lipopolysaccharide (LPS)-induced lung injury. BalB/c mice intraperitoneally received PAP (10 and 20 mg/kg) or dexamethasone (2 mg/kg) 1 h prior to intratracheal instillation of LPS. PAP significantly decreased lung wet-to-dry weight (W/D) ratio and lung myeloperoxidase (MPO) activity and restored LPS-induced lung histopathological changes.

Betulin inhibited cigarette smoke-induced COPD in mice.

The purpose of the present study was to evaluate the protective effect of betulin (BE) on CS (cigarette smoke)-induced COPD in mice and explore its underlying mechanisms. 60 male ICR mice were randomly assigned to five groups: control group, model group, dexamethasone (2mg/kg) group, BE (20mg/kg) group and BE (40mg/kg) group. The COPD mice were induced by cigarette smoke exposure for 8 weeks.

Antihyperuricemic effect of liquiritigenin in potassium oxonate-induced hyperuricemic rats.

The aim is to investigate the anti-hyperuricemic and renal protective effects of liquiritigenin in potassium oxonate-induced hyperuricemic rats. Hyperuricemia in rats was induced were induced with potassium oxonate (250mg/kg) intragastrically for 7 days, and liquiritigenin (20, 40mg/kg) and allopurinol (5mg/kg) were daily administrated to the rats orally 1h after the potassium oxonate exposure. Liquiritigenin significantly reversed the elevated productions of uric acid in serum and urine and pro-inflammation cytokines in serum and kidney, which shown that liquiritigenin has renal protective effects.

Fasudil, an inhibitor of Rho-associated coiled-coil kinase, improves cognitive impairments induced by smoke exposure.

The current study was designed to investigate the pathological changes in brain induced by smoke exposure, and explore whether fasudil could alleviate these impairments.Adult C57BL/6 mice were exposed to tobacco smoking for four months, and fasudil was treated from the third months. To investigate lung injuries, the immunohistochemistry of lung tissue, immune cell infiltrations, cytokine productions in bronchoalveolar lavage (BAL) fluid, and seurm inflammatory cytokines were evaluated.

Retracted: Umbelliferone reverses depression-like behavior in chronic unpredictable mild stress-induced mice via RIP140/NF-κB pathway.

Therapeutic potential of cysteine-rich protein 61 in rheumatoid arthritis.

Cysteine-rich protein 61 (Cyr61)/CCN1, a product of an immediate early gene, can directly accommodate cell adhesion and migratory processes whilst simultaneously regulating the production of other cytokines and chemokines through paracrine and autocrine feedback loops. This intricate functionality of Cyr61 indicate its important role in targeting components of the infectious or chronic inflammatory disease processes including rheumatoid arthritis (RA). Recent work has focused on the role of Cyr61 in RA.

Esculetin attenuates lipopolysaccharide (LPS)-induced neuroinflammatory processes and depressive-like behavior in mice.

Esculetin is one of the major bioactive compounds of Cichorium intybus L. The main purpose of the present study was to investigate the effects and possible underlying mechanism of esculetin (Esc) on lipopolysaccharide (LPS)-induced neuroinflammatory processes and depressive-like behavior in mice. Mice were pretreatment with esculetin (Esc, 20, 40mg/kg, intragastric administration) and a positive control drug fluoxetine (Flu, 20mg/kg, intragastric administration) once daily for 7 consecutive days.

Cytochrome P450 1A1 gene polymorphisms and digestive tract cancer susceptibility: a meta-analysis.

Cytochrome P450 1A1 (CYP1A1) is a phase I enzyme that regulates the metabolism of environmental carcinogens and alter the susceptibility to various cancers. Many studies have investigated the association between the CYP1A1 MspI and Ile462Val polymorphisms and digestive tract cancer (DTC) risk in different groups of populations, but their results were inconsistent. The PubMed and Embase Database were searched for case-control studies published up to 30th September, 2015.

Esculetin Attenuates Th2 and Th17 Responses in an Ovalbumin-Induced Asthmatic Mouse Model.

The purpose of the current study was to investigate the anti-asthmatic effect of esculetin (ES) and explore its potential mechanism with a mouse model of allergic asthma. A total number of 50 mice were randomly assigned to five groups: control, model, dexamethasone (Dex, 2 mg/kg), and ES (20 mg/kg, 40 mg/kg). Mouse asthma model was developed with the sensitization and challenge of ovalbumin (OVA).

Salidroside ameliorates arthritis-induced brain cognition deficits by regulating Rho/ROCK/NF-κB pathway.

The prevalence of cognitive impairment in rheumatoid arthritis (RA) patients was increasingly serious nowadays. The purpose of the current study was to explore whether salidroside (Sal) could alleviate arthritis-induced cognition deficits and examine the relationship between the impairment and Rho/ROCK/NF-κB pathway. Collagen-induced arthritis (CIA) was established by the injection of chicken type II collagen (CII), complete Freund's adjuvant (CFA) and incomplete Freund's adjuvant (IFA).
