The effects of exposure to copper (Cu) on tissue Cu accumulation, on hemolymph osmotic, Na(+) and Cl(-) regulation, and on gill Na(+)/K(+)-ATPase (NKA) and carbonic anhydrase (CA) activities were evaluated in the fiddler crab Minuca rapax. Waterborne copper was delivered to the crabs at one of three salinities (seawater at 25‰ salinity [S] = isosmotic control; distilled water [<0.1‰ S] = hypo-osmotic medium; or 60‰ S = hyper-osmotic seawater) either for 5 days in a 0.5-cm water film containing 0, 50, 150, 250 or 500µg Cu/L with free access to a dry surface, or in crabs fully submerged for 5h at 0, 250 or 500µg Cu/L...

BACKGROUND: The aim was to investigate whether exercise training (ExT) would ameliorate expression of key genes for myocardial morphostructure and mitigate adverse left ventricular (LV) remodeling in experimental type 1 diabetes (T1D). METHODS AND RESULTS: Male Wistar rats were divided into four groups: sedentary control (SC, n=9), trained control (TC, n=13), sedentary diabetic (SD, n=20), and trained diabetic (TD, n=17). T1D was induced by 40 mg/kg streptozotocin (single dose, i...

In previous experiments, we demonstrated that the amount of monoterpenes in sage is increased massively by drought stress. Our current study is aimed to elucidate whether this increase is due, at least in part, to elevated activity of the monoterpene synthases responsible for the biosynthesis of essential oils in sage. Accordingly, the transcription rates of the monoterpene synthases were analyzed. Salvia officinalis plants were cultivated under moderate drought stress. The concentrations of monoterpenes as well as the expression of the monoterpene synthases were analyzed...

The present study was designed to investigate the effects of Astragaloside IV (ASIV) on the immune functions of RAW264.7 cells. Compared with control group, the concentrations of interleukin 1β (IL-1β), tumor necrosis factor α (TNF-α) and nitric oxide (NO) were higher in the 100μg/mL ASIV-treatment group. The interleukin 6 (IL-6) concentration was significantly higher in the 50 and 100μg/mL ASIV-treatment groups. The relative mRNA expression levels of IL-1β, TNF-α and inducible nitric oxide synthase (iNOS) were significantly higher in the 50 and 100μg/mL ASIV-treatment groups...

Although xanthotoxin has been reported to possess skin-protective and anti-oxidative properties, its anti-inflammatory capacity has not been studied to date. Therefore, we investigated this role as well as the molecular mechanisms of xanthotoxin in lipopolysaccharide (LPS)-induced RAW 264.7 macrophages. Xanthotoxin inhibited production of nitric oxide (NO), prostaglandin E2 (PGE2), tumor necrosis factor (TNF-α), and interleukin-6 (IL-6) by the LPS-induced macrophages in a concentration-dependent manner. It also suppressed the LPS-induced inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) expression at the protein levels and iNOS, COX-2, TNF-α, and IL-6 at the mRNA levels...

Autoimmune regulator (Aire) plays an indispensable role in maintaining central immune tolerance by promoting the ectopic expression of tissue-restricted antigens (TRAs) in medullary thymic epithelial cells (mTECs) and dendritic cells (DCs), which lead to the deletion of autoreactive T cells or the induction of Tregs and consequently prevent autoimmune disease development. Curing autoimmune diseases has always been a challenge. DC-based immunotherapy represents a new and effective method to establish tolerance...

BACKGROUND Recent studies identified a set of differentially expressed miRNAs in whole blood that may discriminate neuromyelitis optica spectrum disorders (NMOSD) from relapsing-remitting multiple sclerosis (RRMS). This study invalidated 9 known miRNAs in Chinese patients. MATERIAL AND METHODS The levels of miRNAs in whole blood were assayed in healthy controls (n=20) and patients with NMOSD (n=45), RRMS (n=17) by quantitative real-time polymerase chain reaction (qRT-PCR), and pairwise-compared between groups...

Long noncoding RNAs (lncRNAs), as new class of functional regulators involved in human tumorigenesis, have been attracting increasing attention of researchers. The lncRNA Colorectal Neoplasia Differentially Expressed (CRNDE), transcribed from chromosome 16 on the strand opposite to the adjacent IRX5 gene, were originally found to be increased in CRC and was reported abnormal expressed in many cancers. However, its potential role and molecular mechanism underlying radioresistant phenotype formation of lung adenocarcinoma (LAD) remains unclear...

Recent evidence suggests that dysregulation of microRNAs are associated with the development of multiple malignancies.miR-186 has been reported as a critical cancer regulator in several types of cancers. However, its functional significance and molecular mechanism underlying renal cell carcinoma (RCC) remains unknown. In this study, our results showed that miR-186 expression was dramatically downregulated in RCC tissues and cell lines compared to that in adjacent normal tissues and cell lines. Overexpression of miR-186 significantly inhibited cell growth, colony formation, cell invasion, caused cell cycle arrest at G0/G1 phase, and induced cell apoptosis as detected by MTT, colony formation, Transwell assay, and flow cytometry assays in RCC cells...

Breast cancer is a serious threat to women's physical and psychological health. Long non-coding RNA CAMTA1 (LncCAMTA1)was believed to be related with tumor progression, but its role in breast cancer is not clear. Human breast cancer cell line MDA-MB-231 was used to investigate effect of LncCAMTA1 on cell viability, migration/invasion, and apoptosis. Expression of LncCAMTA1, miR-20b and VEGF in MDA-MB-231were measured after corresponding transfections. Binding effects between LncCAMTA1 and miR-20b, miR-20b and VEGF 3'UTR were measured...

Epithelial ovarian cancer (EOC) is the one of most common gynecological malignant tumor with highest mortality, meanwhile, series of lncRNAs have been validated to play vital role in EOC tumorigenesis. Colon cancer-associated transcript 2 (CCAT2) has been verified as oncogenic lncRNA in multiple tumors, however, the role of CCAT2 in EOC genesis is still unclear. The purpose of present study is to probe the function of CCAT2 on EOC. Preliminary experiments found that CCAT2 expression was significantly up-regulated in EOC tissue and cell lines compared to noncancerous tissue and cells...

MicroRNAs (miRs) have been found to play promoting or suppressive roles in different human cancers. However, the exactregulatory mechanism of miR-30b in glioblastoma still remains unknown. Here we showed that the expression of miR-30b was significantly increased in glioblastoma tissues and cell lines. Moreover, high expression of miR-30b was significantly associated with shorter survival time of glioblastoma patients. Knockdown of miR-30b caused a significant reduction in the proliferation, migration, and invasion of U87 and A172 cells...

Drug resistance is the major obstacle for the successful therapy of lung adenocarcinoma. It was suggested that ß-elemene, a major isoform of elemene, could reverse the drug resistance in lung cancer cells. However, the underlying mechanisms remains poorly known. Here, we aimed to investigate whether elemene is involved in the cisplatin (DDP)-resistance of lung adenocarcinoma cells and further explore the underlying mechanism. The results showed that human lung adenocarcinoma cell line SPC-A-1 and its DDP-resistant strain SPC-A-1/DDP had a similar sensitivity to elemene treatment...

MicroRNAs play an important role in regulating gene expression by binding to the 3' UTR of target mRNAs. In this studywe have made an attempt to assess the molecular mechanisms by which miR-32 suppresses the expression of SRCIN1, thereby leading to promotion of proliferation and epithelial-mesenchymal transition of human liver cancer cells. Human liver cancer cell lines HepG2 were transfected with miR-32 mimics and its control. The HepG2 cell lines were the assessed for miR-32 expression. The transfected cell lines were then studied for SRCIN1 expression by luciferase assay, effect of transfection on cell proliferation and finally epithelial-mesenchymal transition...

Evidence suggests that the long non-coding RNA (lncRNA) metastasis-associated lung adenocarcinoma transcript 1 (MALAT1)is upregulated in cancer tissues and its elevated expression is associated with hyper-proliferation. However, the underlying mechanisms regarding the role of MALAT1 in retinoblastoma (RB) remains unclear. This study aimed to explore the functional role of MALAT1 in RB by targeting miR-124. Results showed that the expression of - MALAT1 was significantly higher in Y79 cell line than ARPE-19 cell line (P<0...
