In the present review, the main characteristics of giant-cell arteritis-related stroke are discussed.Thyroid 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. The present study aimed to explore the effects of curcumin on the viability, migration and invasion of PTC cells. TPC-1 cells were incubated with different concentrations of curcumin, and then, cell viability, migration and invasion, and wound healing were examined by CCK-8, Transwell and wound healing assays, respectively. Subsequently, microRNA (miR)-301a-3p mimics, miR-301a-3p inhibitors and signal transducer and activator of transcription (STAT)3 overexpression vector were transfected into TPC-1 cells, and cell viability, migration, and invasion were reassessed in these transfected cells. Matrix metallopeptidase (MMP)-2, MMP-9, epithelial-mesenchymal transition (EMT)-related markers, and Janus kinase (JAK)/STAT signaling pathway components were assessed by western blot analysis. Curcumin significantly inhibited cell viability, migration and invasion and downregulated MMP-2, MMP-9 and EMT marker expression. Additionally, curcumin decreased STAT3 expression by upregulating miR-301a-3p expression, and the inhibition of miR-301a-3p and the overexpression of STAT3 reversed the effects of curcumin on cell viability, migration and invasion, and MMP-2, MMP-9 and EMT marker expression in TPC-1 cells. Furthermore, curcumin suppressed the JAK/STAT signaling pathway through the miR-301a-3p/STAT3 axis. The data of the present study indicated that curcumin could inhibit the viability, migration and invasion of TPC-1 cells by regulating the miR-301a-3p/STAT3 axis. These findings may provide a possible strategy for the clinical treatment of PTC.Long non-coding RNAs (lncRNAs) serve major roles in diabetic nephropathy (DN). The present study investigated the regulatory mechanism of lncRNA non-coding RNA activated by DNA damage (NORAD) on DN in vitro. Reverse transcription-quantitative polymerase chain reaction (RT-qPCR) was used to detect the expression of lncRNA NORAD, microRNA-485 (miR-485) and nuclear respiratory factor 1 (NRF1) in the tissues of patients with DN and high-glucose (HG)-induced human mesangial cells (HMCs). The viability of HMCs was determined using an MTT assay. The levels of inflammatory [tumour necrosis factor (TNF)-α, interleukin (IL)-1β and IL-6] and fibrotic [type IV collagen (Col. IV), fibronectin (FN) and plasminogen activator inhibitor 1 (PAI-1)] factors in HMCs were measured by ELISA. The interactions between miR-485 and NORAD/NRF1 were predicted using StarBase and miRDB softwares and confirmed by a dual-luciferase reporter assay. Western blot analysis was utilized to measure NRF1 protein levels. lncRNA NORAD was highly expressed in tissues and HG-induced HMCs. NORAD knockdown suppressed cell viability in HG-induced HMCs. The levels of the inflammatory and fibrotic factors in HG-induced HMCs were inhibited by NORAD knockdown. ISRIB chemical structure miR-485 was the direct target of NORAD. NORAD reversed the inhibitory effects of miR-485 on HG-induced HMCs. Furthermore, NRF1 was the target gene of miR-485. Downregulation of miR-485 and upregulation of NRF1 reversed the inhibitory effects of NORAD knockdown on HG-induced HMCs. NORAD knockdown inhibited HG-induced HMC proliferation, inflammation and fibrosis by regulating miR-485/NRF1, providing a possible therapeutic strategy for DN.MicroRNAs (miRNAs/miRs) 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 miR-320a in serum exosomes, as well as the effect of miR-320a 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 transcription-quantitative 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 miR-320a expression levels and sST2 content were significantly increased in patients with CHF compared with healthy controls, and the expression of serum miR-320a was significantly correlat-320a promoted myocardial fibroblast proliferation via regulating the PIK3CA/Akt/mTOR signaling pathway in HEH2 cells, suggesting that serum exosomal miR-320a may serve as a potential biomarker for the diagnosis of CHF.Chronic 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 Epstein-Barr virus (EBV) affects ~90% of the population and experimental evidence suggested that curcumin mediates cytotoxicity against EBV-infected 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 iAs-related toxicity in EBV-infected cells. Two independent EBV-immortalized 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 pre-incubated 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 concentration-dependent manner. Furthermore, curcumin pre-treatment enhanced iAs-induced cell death and promoted cell cycle arrest in G1 phase. Taken together, these results suggested that curcumin sensitizes EBV-positive LCLs to the cytotoxic effects of iAs.
