A Novel Long-Noncoding RNA LncZFAS1 Prevents MPP-Induced Neuroinflammation Through MIB1 Activation.

Parkinson's disease remains one of the leading neurodegenerative diseases in developed countries. Despite well-defined symptomology and pathology, the complexity of Parkinson's disease prevents a full understanding of its etiological mechanism. Mechanistically, α-synuclein misfolding and aggregation appear to be central for disease progression, but mitochondrial dysfunction, dysfunctional protein clearance and ubiquitin/proteasome systems, and neuroinflammation have also been associated with Parkinson's disease.

Increased activation of the caudate nucleus and parahippocampal gyrus in Parkinson's disease patients with dysphagia after repetitive transcranial magnetic stimulation: a case-control study.

Repetitive transcranial magnetic stimulation (rTMS) has been shown to effectively improve impaired swallowing in Parkinson's disease (PD) patients with dysphagia. However, little is known about how rTMS affects the corresponding brain regions in this patient group. In this case-control study, we examined data from 38 PD patients with dysphagia who received treatment at Beijing Rehabilitation Medicine Academy, Capital Medical University.

Protective Effect of miR-374a on Chemical Hypoxia-Induced Damage of PC12 Cells In Vitro via the GADD45α/JNK Signaling Pathway.

To explore the effect of microRNA-374a (miR-374a) on chemical hypoxia-induced pheochromocytoma (PC12) cell damage by mediating growth arrest and the DNA damage-45 alpha (GADD45α)/c-Jun N-terminal kinase (JNK) signaling pathway. PC12 cells were divided into a Control group (no treatment), Model group (treated with CoCl for 24 h), negative control (NC) group (transfected with miR-374a negative control sequence and treated with CoCl for 24 h), and miR-374a mimic group (transfected with miR-374a mimics and treated with CoCl for 24 h). The viability and apoptosis of PC12 cells were determined by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay and flow cytometry, while the mitochondrial membrane potential (MMP) and reactive oxygen species (ROS) content were assessed by Rh123 and dichloro-dihydro-fluorescein diacetate (DCFH-DA) methods.

TRC8 downregulation contributes to the development of non-alcoholic steatohepatitis by exacerbating hepatic endoplasmic reticulum stress.

Endoplasmic reticulum (ER) stress is implicated in the pathogenesis of nonalcoholic fatty liver disease (NAFLD). TRC8 is an ER-resident E3 ligase with roles in modulating lipid and protein biosynthesis. In this study we showed that TRC8 expression was downregulated in steatotic livers of patients and mice fed with a high fat diet (HFD) or a methionine and choline deficient (MCD) diet.

Robust biomimetic-structural superhydrophobic surface on aluminum alloy.

The following facile approach has been developed to prepare a biomimetic-structural superhydrophobic surface with high stabilities and strong resistances on 2024 Al alloy that are robust to harsh environments. First, a simple hydrothermal treatment in a La(NO3)3 aqueous solution was used to fabricate ginkgo-leaf like nanostructures, resulting in a superhydrophilic surface on 2024 Al. Then a low-surface-energy compound, dodecafluoroheptyl-propyl-trimethoxylsilane (Actyflon-G502), was used to modify the superhydrophilic 2024 Al, changing the surface character from superhydrophilicity to superhydrophobicity.

Activator protein-2α mediates carbon monoxide-induced stromal cell-derived factor-1α expression and vascularization in ischemic heart.

Objective: Increased cardiac stromal cell-derived factor-1α (SDF-1α) expression promotes neovascularization and myocardial repair after ischemic injury through recruiting stem cells and reducing cardiomyocyte death. Previous studies have shown that heme oxygenase-1 and its reaction byproduct, carbon monoxide (CO), induce SDF-1α expression in ischemic heart. However, the mechanism underlying heme oxygenase-1/CO-induced cardiac SDF-1α expression remains elusive.

Areca nut procyanidins ameliorate streptozocin-induced hyperglycemia by regulating gluconeogenesis.

Hepatic gluconeogenesis is a major contributor to blood glucose in diabetes mellitus. Our previous study indicated that areca nut extract enriched with catechin-based procyanidins from oligomers to polymers gave rise to anti-inflammatory effects in vitro and in vivo. Here we have surveyed the molecular features of areca nut procyanidins (ANPs) using quadrupole time-of-flight liquid chromatography/mass spectrometry (Q-TOF LC/MS) and the resulting mass spectrum accurately described ANP from monomer to hexadecamer.

Effects of Areca catechu L. containing procyanidins on cyclooxygenase-2 expression in vitro and in vivo.

Polyphenols are widely distributed in plants and known for antioxidant and anti-inflammatory properties. Areca nut, rich in polyphenols, is the major component of betel quid and we have previously shown that the extract of areca nut can induce oxidative stress in vitro. In this study, we have further pinpointed that areca nut extract (ANE) contains catechin based procyanidins which range from dimers to decamers and polymers; this was carried out by HPLC and electrospray ionization/mass spectrometry (ESI/MS).

Highly oligomeric procyanidins from areca nut induce lymphocyte apoptosis via the depletion of intracellular thiols.

Procyanidins are plant-derived polyphenolic compounds possessing a variety of biological activities, such as immunomodulation, and induction of tumor cell apoptosis. We previously reported that total extract of areca nut exhibited a suppressive effect on the metabolic activity and cytokine expression in normal splenic lymphocytes. As areca nut contains a rich amount of polyphenols, the objective of the present study was to investigate the pro-apoptotic effect of polyphenol-enriched areca nut extract (PANE) and its fractionated oligomeric procyanidins in splenic lymphocytes.

Inhibition of DLC-1 gene expression by RNA interference in the colon cancer LoVo cell line.

DLC-1 (deleted in liver cancer-1) is a potential tumor suppressor gene, which is inactive in liver carcinogenesis. To observe the effects of DLC-1 gene expression on cell proliferation and migration in the human colon cancer cell line, RNAi Lipo-recombinant of the DLC-1 gene (pGCsil-DLC-1) was constructed and transduced into LoVo cells which are positive for DLC-1 gene expression. Results showed that the RNAi recombinant effectively inhibited the expression of the DLC-1 gene in LoVo cells.
