These results show that ATF treatment targeting the HBV core protein promoter has an antiviral effect and inhibits HBV infection in host cells. These results further suggest that the design of new artificial transcription factors may be valuable antiviral therapies to treat HBV patients. © 2020 by the Association of Clinical Scientists, Inc.The aim of the present study is to investigate the effect of cyclopamine, a hedgehog signaling pathway inhibitor, on adjuvant arthritis (AA), rat articular chondrocyte viability, and part mechanisms in vitro In this study, an AA rat model was established by Freund's complete adjuvant (FCA). The arthritis index (AI), secondary paw swelling degree, and HE staining were used to evaluate whether the model was successfully established. Chondrocytes of the ankle joint of AA rats were cultured and identified. Cyclopamine (0, 0.03, 0.1, 0.3, 1, 3, 10 and 30 mg/l) was administered to determine chondrocyte viability. Chondrocyte apoptosis was detected by Annexin V-FITC/PI double dye. The expression of hedgehog signaling pathway-related proteins Shh, Ptch1, and Gli1 in chondrocytes was detected by western blotting. The results show that AA was successfully induced by FCA since the AI of AA rats and secondary paw swelling degree increased and the cartilage tissue of the rats' ankle joint was damaged. Thus, the chondrocytes were successfully cultured in vitro following the identification of toluidine blue and type II collagen. Cyclopamine (0.03, 0.1, 0.3, 1, 3, 10 and 30 mg/l) could increase the viability of chondrocytes in vitro and reduce the apoptotic rate of chondrocytes. As compared with the control group, different doses of cyclopamine (0.3, 3 and 10 mg/l) significantly decreased the expression of Shh, Ptch1 and Gli1 proteins in AA chondrocytes. Therefore, an AA rat model was successfully established in the present study and cyclopamine improved the viability and inhibited the apoptosis of chondrocytes. This is an effect that may be associated with the inhibition of the chondrocyte hedgehog signaling pathway. © 2020 by the Association of Clinical Scientists, Inc.OBJECTIVE To investigate the relationship of polymorphism in vascular cell adhesion molecule-1 (VCAM-1) and intercellular adhesion molecule-1 (ICAM-1) with preeclampsia (PE). METHODS The present study included 252 patients with PE and 200 healthy pregnant women as control admitted to our hospital from February 2012 to December 2016. Allelic discrimination of the rs5498 polymorphisms from the ICAM-1 gene and rs3181092 from the VCAM-1 gene was assessed using the TaqMan assay. Data was analyzed using SPSS 18.0. RESULTS In PE patients, both ratios of AA and AA+AG genotypes of VCAM-1 were significantly higher than those in the control group, P less then 0.05. The comparison of genotypes between PE patients with early-onset and late-onset showed that late-onset PE patients had a higher ratio of AA genotype in VCAM-1, P less then 0.05. Similarly, the ratio of genotype AA in severe PE was significantly higher than that in mild PE patients, P less then 0.05. However, the distribution of rs5498 polymorphism for ICAM-1 showed no significant difference in the groups. CONCLUSION Rs3181092 polymorphism of VCAM-1 was associated with occurrence of PE, especially for late-onset and severe PE. However, whether rs5498 polymorphism of ICAM-1was associated with PE needs more investigation. © 2020 by the Association of Clinical Scientists, Inc.OBJECTIVE Cervical cancer is the fourth most deadly women's cancer worldwide, and regular screening is essential to lower mortality rates. The folate receptor-mediated staining solution detection (FRD) has been suggested to be a rapid and cost-effective screening method. We aim to evaluate the validity of FRD testing in cervical cancer screening. METHODS A total of 207 participants were enrolled in the study. The validity of screening by FRD, cytology screening, and a HPV test were compared using histopathology as the gold standard. Sensitivity, specificity, positive predictive value, negative predictive value, Kappa value, positive likelihood ratio, negative likelihood ratio, percent agreement, and positive detection rates were compared among the three screening methods. RESULTS 83(40.1%) participants were diagnosed as NILM, 50(24.15%) were diagnosed as CIN1, and 74(35.74%) were diagnosed as CIN2+. For CIN2+, the detection rates for the FRD, cytology screening, and HPV were 75.68%, 82.09% and 93.22%, respectively. For CIN2+, the sensitivity of HPV testing (93.22%) was significantly higher than that of cytology screening (82.09%) and FRD (75.68%), while the specificity of FRD (63.91%) was higher than that of cytology screening (35.34%) and HPV test (7.56%). The percent agreement and Kappa value of FRD were significantly higher than those of the cytology screening and HPV test. https://www.selleckchem.com/HSP-90.html In HPV-HC2+ and ASCUS patients, FRD was associated with a lower false positive rate compared to other screening methods. CONCLUSION Our study indicates that FRD has a good sensitivity and high specificity in cervical cancer screening, and could be a rapid, valid and cost-effective screening test. © 2020 by the Association of Clinical Scientists, Inc.Melatonin is an amine hormone produced by mammals and the human pineal gland. Modern biomedical research has shown that melatonin has antitumor effects. However, the underlying mechanisms of these effects remain unclear. In this study, we explore the effect of melatonin on TE-1 esophageal cancer cells metastasis and study the roles of the NF-κB signaling pathway and MMP9 in this process. We found that melatonin significantly suppressed the migration and invasion of TE-1 esophageal cancer cells, inhibited the activation NF-κB signaling pathway, and decreased the expression of MMP9. When adding NF-κB inhibitor, the results show that the expression of MMP9 decreased while E-cadherin increased. Taken together, the results indicate that melatonin inhibits esophageal cancer cell metastasis by down-regulating the NF-κB signaling pathway and MMP9. Therefore, melatonin may be a new drug for the effective treatment of esophageal cancer. © 2020 by the Association of Clinical Scientists, Inc.
