The results indicated that miR-145-5p overexpression inhibited SCC9 and Cal27 cell stability and invasion, promoted SCC9 and Cal27 cell apoptosis and oxidative stress, and inhibited the PI3K/AKT signaling pathway. The results of the present study suggested that miR-145 may serve as a molecular marker of TSCC.DEC1 has been reported to regulate the expression of multiple target genes, participate in cell differentiation, apoptosis, aging and the development and progression of numerous tumors, but the detailed effects and possible mechanisms of DEC1 in ovarian cancer (OC) remain unknown. Veliparib cost The present study aimed to investigate the expression and mechanism of function of DEC1 in OC. The present results demonstrated that DEC1 was highly expressed in OC tissues and cell lines using reverse transcription-quantitative PCR, western blotting and immunohistochemistry, and high expression of DEC1 was negatively associated with the prognosis of patients with OC. In addition, knockdown of DEC1 significantly inhibited proliferation in SKOV3 and OVCAR3 cells compared with control. DEC1 knockdown also induced apoptosis and increased the expression of apoptosis-related proteins in OC cells. The results suggested that knockdown of DEC1 inhibited OC cell migration and invasion via regulation of epithelial-mesenchymal transition-related protein. It was also found that DEC1 knockdown significantly inhibited the Wnt/β-catenin pathway. Collectively, the current results indicated that knockdown of DEC1 inhibited proliferation, migration and invasion, and induced apoptosis in OC cells via modulating the Wnt/β-catenin signaling pathway. Thus, DEC1 may participate in malignant progression of OC, and may be a target for treatment and diagnosis of OC.It has been shown that flickering light can affect the development of eyeballs. However, the exact mechanism remains unclear. The ERK1/2-MMP-2 pathway is a classic pathway involved in the modulation of the extracellular matrix (ECM) in cancer tissues. However, to the best of our knowledge, the role of this pathway in modulating the scleral ECM in myopia has not been previously examined. The present study aimed to determine the effects of the ERK1/2-MMP-2 pathway on the formation of flickering light-induced myopia (FLM). Guinea pigs were raised under illumination at a flash rate of 0.5 Hz for 6 weeks to induce FLM. Peribulbar injections of dimethylsulfoxide or PD98059 (an inhibitor of phospho-ERK1/2) were administered starting at the third week of FLM modeling. Refraction was measured prior to and following treatments. The thickness of the posterior sclera (PS) was measured under a light microscope following H&E staining. The mRNA levels of MMP-2 were detected by the reverse transcription-quantitative PCR assay. The expression levels of MMP-2 and ERK1/2 were assayed by western blot and immunohistochemical analyses. Following 6 weeks of treatment, the refraction of the FLM group became more myopic compared with that of the control group, while PD98059 treatment inhibited the changes noted in the refraction. A marked reduction in the thickness of PS was observed in the FLM group, while PD98059 inhibited the remodeling of PS. In addition, the expression levels of MMP-2 and protein levels of phospho-ERK1/2 were increased in the FLM group, while PD98059 significantly inhibited MMP-2 mRNA and protein levels. These results indicated that ERK1/2-MMP-2 may be involved in the formation of FLM in guinea pigs by regulating the remodeling of PS.The present study aimed to evaluate the use of 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET) for detection of high-fat and high-salt diet-induced inflammatory lesions of the arterial vessel walls in Wistar rats. A total of 20 healthy, 8-week-old, male Wistar rats were randomly assigned to the high-fat diet group and the normal diet group. After 16 and 24 weeks of feeding, Wistar rats in the normal diet group and the high-fat diet group (five rats in each group) were injected with 18F-FDG through the tail vein at a dose of 1 mCi/kg after fasting for 12 h. After 1 h, the rats were anesthetized with 2% isoflurane, followed by micro-PET imaging with a 10-min image capture duration and immunohistochemical staining. The standardized uptake values (SUVs) of 18F-FDG were significantly higher in the iliac artery in the high-fat diet group compared with those in the normal diet group at 16 weeks (1.53±0.08 vs. 1.04±0.03; P less then 0.05) and at 24 weeks (1.96±0.17 vs. 1.12±0.07; P less then 0.05)ly monitor inflammatory lesions of the arterial vessel walls in Wistar rats. Further improvement of the Wistar rat atherosclerosis model may provide data to support the early assessment of and intervention in atherosclerosis.Alveolar macrophages are the front-line defense against environmental pathogens. However, to the best of our knowledge, differences in function and phenotypic expression levels of macrophages between neonatal and adult lungs have not previously been determined. The present study investigated lung tissues and analyzed blood samples to find cell markers of M1 and M2 macrophages in neonatal and adult rats. Pulmonary sepsis was induced by intrapleural instillation of lipopolysaccharide (LPS; 20 mg/kg) and survival time after administration of LPS was measured. In certain neonates, a selective inducible nitric oxide synthase (iNOS) inhibitor, 1400w, was administered prior to induction of pulmonary sepsis. Compared with adults, fetal and neonatal lung tissues had significantly higher levels of iNOS and CD86 (M1 markers), whereas the expression levels of CD206 and arginase-1 (M2 markers) were lower in the neonatal lung. The circulating cells that co-expressed CD68 (monocytes and macrophages) and CD86 in the blood were also significantly higher in neonates than in adults (25.9±6.6 vs. 11.6±2.2%; P=0.007. At basal unstimulated conditions, lung tissue concentrations of nitrite and nitrate (NOx) were significantly lower in the neonates than in adults (112.1±55.9 vs. 340.9±124.9 µM/g; P less then 0.001). However, NOx was increased following administration of LPS. Administration of 1400w suppressed lung tissue levels of NOx and improved the survival time in neonatal rats treated with LPS. The present study demonstrated that M1 is the primary macrophage phenotype in the neonatal lung and that higher iNOS expression levels do not have a protective effect against pulmonary endotoxins in neonates. Overproduction of NO by iNOS in neonatal alveolar macrophages may result in detrimental effects during pulmonary inflammation.
