BACKGROUND: Chronic obstructive pulmonary disease (COPD) is managed by three major classes of inhaled medications: inhaled corticosteroids (ICS), long-acting Beta 2-agonist (LABA), long-acting muscarinic antagonist (LAMA). Single inhaled medication is usually replaced by combined inhaled medications for efficacy enhancement. However, this practice should be supported by clinical evidence for large-scale implementations. METHODS: The relative efficacy of inhaled medications is determined by three endpoints: changes in the trough forced expiratory volume in 1 second (tFEV1), changes in the St George's Respiratory Questionnaire (SGRQ) score and the proportion of SGRQ responders which represents a reduction in SGRQ total score at week 24 of ≥4...

BACKGROUND/AIMS: MicroRNA-9 (miR-9) is involved in inflammatory reaction in atherosclerosis; however, its function and regulatory mechanisms remain unclear. We aimed to uncover the exact roles of miR-9 and downstream signaling pathways using in vitro human atherosclerosis models. METHODS: We used oxidized low-density lipoprotein (oxLDL)-stimulated human THP-1 derived macrophages, oxLDL-stimulated human primary peripheral blood monocytes and lipopolysaccharides (LPS) or Alum-stimulated human THP-1 derived macrophages as in vitro atherosclerosis inflammation models...

BACKGROUND/AIMS: Dysregulation of ubiquitin-associated protein 2-like (UBAP2L) has been reported in tumors, but its role in hepatocellular carcinoma (HCC) progression is unclear. METHODS: The expression levels of UBAP2L in HCC tissues and HCC cell lines were detected by western blot and quantitative real-time (qRT) PCR. The effects of UBAP2L expression on HCC cell biological traits, including migration and invasion, were investigated by wound healing assay and matrigel transwell assay...

BACKGROUND: The protection of endothelial cells (ECs) against reperfusion injury has received little attention. In this study, we used Tandem Mass Tag (TMT) labeling proteomics to investigate the modulated proteins in an in vitro model of cardiac microvascular endothelial cells (CMECs) subjected to ischemia/reperfusion (I/R) injury and their alteration by traditional Chinese medicine Tongxinluo (TXL). METHODS: Human CMECs were subjected to 2 h of hypoxia followed by 2 h of reoxygenation with different concentrations of TXL Protein expression profiles of CMECs were determined using tandem mass spectrometry...

BACKGROUND: Currently, there is a global attempt to identify potential anti-cancer agents with low toxicity. Previous studies have found that glycyrrhizin exerts anti-cancer action with low toxicity through suppressing thromboxane A2 (TxA2) in lung cancer cell lines. However, these effects have not yet been determined in animal models of lung cancer. METHODS: Human lung adenocarcinoma xenografts were established in nude mice by the introduction of A549 cells with stable transfection of the TxA2 receptor (TPα)...

OBJECTIVE: To identify the molecular mechanism of post-stroke depression (PSD), and observe the therapeutic effects of cerebellar fastigial nucleus electrical stimulation (FNS) on the behaviors and regional cerebral blood flow (rCBF) in a PSD rat model. METHODS: Healthy SD rats were randomly divided into four groups (sham, stroke, post-stroke depress and FNS group). Sham group (n = 6) underwent sham operation. The other three groups (n = 6*3) underwent MCAO. Rats were examined twice a week in open filed test...

Backgroud: Age-related macular degeneration (AMD) is one of the leading causes of irreversible blindness of the elder people. This research was intended to demonstrate the different expression of microRNAs (miRNA) in AMD patients and whether they can be used as biomarkers for AMD. METHODS: MiRNAs expression was measured by microarray of 6 AMD cases and 6 gender matched controls. In a larger-sample case-control study with 126 AMD cases and 140 controls, whole blood samples were detected for the differences of miRNA expression...

BACKGROUND/AIMS: Evidence suggests that IL-6 affects bone mass by modulating osteocyte communication towards osteoclasts. However, the mechanism by which IL-6 enhances osteocyte-mediated osteoclastogenesis is unclear. We aimed to investigate the inflammatory factors in serum after orthodontic surgery and their relationship between osteocytes and osteoclasts. METHODS: Serum was obtained from 10 orthognathic surgery patients, and inflammatory factors were detected by ELISA...

BACKGROUND/AIMS: Pro-angiogenic factors VEGF and IL-8 play a major role in modulating the migratory potential of endothelial cells. The goal of this study was to investigate the effect of autocrine VEGF and IL-8 in the form of self-conditioned medium (CM) on human umbilical vein endothelial cells (HUVECs). METHODS: Enzyme-linked immunosorbent assay (ELISA) examined the automatic secretion of VEGF and IL-8 protein by HUVECs. Western blot, small interfering RNA (siRNA), pulldown and Transwell assays were used to explore the role and the mechanism of autocrine VEGF and IL-8 in migration of HUVECs...

BACKGROUND: Bacillus Calmette-Guérin (BCG) immunotherapy plays a key role in patients with bladder cancer. The shortage of intravesical BCG has motivated researchers to seek alternatives with equivalent efficacy If other alternative intravesical agents have equivalent efficacy compared to BCG, then it may be feasible to replace standard BCG with alternative options. METHODS: We searched all relevant evidence in multiple sources and key data was extracted from included studies...

BACKGROUND: Genomic DNA methylation plays an important role in both the occurrence and development of bladder cancer. Kaempferol (Kae), a natural flavonoid that is present in many fruits and vegetables, exhibits potent anti-cancer effects in bladder cancer. Similar to other flavonoids, Kae possesses a flavan nucleus in its structure. This structure was reported to inhibit DNA methylation by suppressing DNA methyltransferases (DNMTs). However, whether Kae can inhibit DNA methylation remains unclear...

BACKGROUND/AIMS: Aspirin has been demonstrated to possess potent chemopreventive and anticancer effects on prostate cancer. However, the more detailed molecular mechanisms of aspirin to suppress prostate cancer cell invasion have not been clearly elucidated. METHODS: Transwell assays were performed to evaluate the effects of aspirin on cell invasion. Matrix metalloproteinases (MMPs) and serine proteinases activities in cell media were examined by gelatin zymography and ELISA...

BACKGROUND/AIMS: Hypoxia occurs in many pathological conditions, including inflammation and cancer. Within this context, hypoxia was shown to inhibit but also to promote T cell responses. Due to this controversial function, we aimed to explore whether an insufficient anti-tumour response during colitis-associated colon cancer could be ascribed to a hypoxic microenvironment. METHODS: Colitis-associated colon cancer was induced in wildtype mice, and hypoxia as well as T cell immunity were analysed in the colonic tumour tissues...

BACKGROUND/AIMS: Hypoacetylation caused by aberrant epigenetic nuclear reprogramming results in low efficiency of mammalian somatic cell nuclear transfer (SCNT). Many epigenetic remodeling drugs have been used in attempts to improve in vitro development of porcine SCNT embryos. In this study, we examined the effects of LAQ824, a structurally novel histone acetylase inhibitor, on the nuclear reprogramming and in vitro development of porcine SCNT embryos. METHODS: LAQ824 treatment was supplemented during the culture of SCNT embryos...

OBJECTIVES: We aimed to confirm whether RASSF10 activated the p53 signalling pathway, thereby modulating cell proliferation, migration, invasion, and apoptosis in papillary thyroid carcinoma (PTC) cells. METHODS: A total of 108 PTC tissue samples and normal adjacent tissues were obtained. RT-PCR and Western blotting analyses were performed to detect RASSF10 expression, and methylation levels of RASSF10 were estimated by methylation-specific PCR (MSP). We also detected the expression and methylation status of RASSF10 in both a human PTC cell line (K1) and a normal thyroid cell line (FRTL5)...
