In the present review the main characteristics of giantcell arteritisrelated stroke are discussedThyroid cancer is one of the most common malignant tumors and the mortality rate associated with thyroid cancer has been increasing annually Curcumin has been reported to exert an antitumor effect on papillary thyroid cancer PTC and the identification of additional mechanisms underlying the anticancer effect of curcumin on PTC requires further investigation CNO agonist supplier The present study aimed to explore the effects of curcumin on the viability migration and invasion of PTC cells TPC1 cells were incubated with different concentrations of curcumin and then cell viability migration and invasion and wound healing were examined by CCK8 Transwell and wound healing assays respectively Subsequently microRNA miR301a3p mimics miR301a3p inhibitors and signal transducer and activator of transcription STAT3 overexpression vector were transfected into TPC1 cells and cell viability migration and invasion were reassessed in these transfected cells Matrix metallopeptidase MMP2 MMP9 epithelialmesenchymal transition EMTrelated markers and Janus kinase JAKSTAT signaling pathway components were assessed by western blot analysis Curcumin significantly inhibited cell viability migration and invasion and downregulated MMP2 MMP9 and EMT marker expression Additionally curcumin decreased STAT3 expression by upregulating miR301a3p expression and the inhibition of miR301a3p and the overexpression of STAT3 reversed the effects of curcumin on cell viability migration and invasion and MMP2 MMP9 and EMT marker expression in TPC1 cells Furthermore curcumin suppressed the JAKSTAT signaling pathway through the miR301a3pSTAT3 axis The data of the present study indicated that curcumin could inhibit the viability migration and invasion of TPC1 cells by regulating the miR301a3pSTAT3 axis These findings may provide a possible strategy for the clinical treatment of PTCLong noncoding RNAs lncRNAs serve major roles in diabetic nephropathy DN The present study investigated the regulatory mechanism of lncRNA noncoding RNA activated by DNA damage NORAD on DN in vitro Reverse transcriptionquantitative polymerase chain reaction RTqPCR was used to detect the expression of lncRNA NORAD microRNA485 miR485 and nuclear respiratory factor 1 NRF1 in the tissues of patients with DN and highglucose HGinduced human mesangial cells HMCs The viability of HMCs was determined using an MTT assay The levels of inflammatory tumour necrosis factor TNFα interleukin IL1β and IL6 and fibrotic type IV collagen Col IV fibronectin FN and plasminogen activator inhibitor 1 PAI1 factors in HMCs were measured by ELISA The interactions between miR485 and NORADNRF1 were predicted using StarBase and miRDB softwares and confirmed by a dualluciferase reporter assay Western blot analysis was utilized to measure NRF1 protein levels lncRNA NORAD was highly expressed in tissues and HGinduced HMCs NORAD knockdown suppressed cell viability in HGinduced HMCs The levels of the inflammatory and fibrotic factors in HGinduced HMCs were inhibited by NORAD knockdown miR485 was the direct target of NORAD NORAD reversed the inhibitory effects of miR485 on HGinduced HMCs Furthermore NRF1 was the target gene of miR485 Downregulation of miR485 and upregulation of NRF1 reversed the inhibitory effects of NORAD knockdown on HGinduced HMCs NORAD knockdown inhibited HGinduced HMC proliferation inflammation and fibrosis by regulating miR485NRF1 providing a possible therapeutic strategy for DNMicroRNAs miRNAsmiRs serve an important role in the pathogenesis of chronic heart failure CHF A number of reports have illustrated the regulatory effect of serum exosomal miRNA on myocardial fibrosis The present study aimed to investigate the expression of miR320a in serum exosomes as well as the effect of miR320a on myocardial fibroblast proliferation Serum exosome samples from 10 patients with CHF and 5 healthy volunteers were obtained and characterized mRNA and protein expression levels were measured via reverse transcriptionquantitative PCR and western blotting respectively The content of soluble growth stimulation expressed gene 2 sST2 was determined via ELISA HEH2 cell viability and apoptosis were detected by performing MTT assays and flow cytometry respectively The results demonstrated that serum miR320a expression levels and sST2 content were significantly increased in patients with CHF compared with healthy controls and the expression of serum miR320a was significantly correlat320a promoted myocardial fibroblast proliferation via regulating the PIK3CAAktmTOR signaling pathway in HEH2 cells suggesting that serum exosomal miR320a may serve as a potential biomarker for the diagnosis of CHFChronic exposure to inorganic arsenic iAs through contaminated drinking water is an important health problem in certain countries The use of phytochemicals such as curcumin has recently emerged as an alternative strategy for preventing cellular damage caused by iAs The EpsteinBarr virus EBV affects 90 of the population and experimental evidence suggested that curcumin mediates cytotoxicity against EBVinfected cells Due to the potential for an interaction of these factors the aim of the present study was to evaluate the effect of this phytochemical on iAsrelated toxicity in EBVinfected cells Two independent EBVimmortalized human lymphoblastoid cell lines LCLs were used as the model The cell lines were first incubated with increasing concentrations of curcumin or iAs for 24 and 15 h respectively to determine the individual effects of each exposure on cell death In the next experiment cell cultures were preincubated with 5 µM curcumin for 9 h prior to treatment with 10 µM iAs for 15 h followed by evaluation of cell death and the cell cycle profile via flow cytometry The results indicated that individual treatment with either curcumin or iAs induced cell death in a concentrationdependent manner Furthermore curcumin pretreatment enhanced iAsinduced cell death and promoted cell cycle arrest in G1 phase Taken together these results suggested that curcumin sensitizes EBVpositive LCLs to the cytotoxic effects of iAs
