https://www.selleckchem.com/products/gsk3685032.html miR-21 targeted the inhibition of A20 expression. Conclusion miR-21 can promote the expression of NF-κB and NLRP3 in RAW264.7 cells and its mechanism may be related to the targeted inhibition of A20.Objective To investigate the effects of the interaction between Wnt/β-catenin signal and NADPH oxidase 4 (NOX4) on the proliferation of pulmonary epithelial cells in response to silica exposure. Methods The airway instillation of silica to C57BL/6 mice was used to produce mouse silicosis models. Immunohistochemistry was used to determine NOX4 expression in the lungs of silicosis mice. Human lung epithelial cells (BEAS-2B) were exposed to silica to generate an oxidative injury epithelial cell model in vitro. Wnt signal conditioned medium (Wnt3a-CM) and Wnt signal inhibitor XAV939 were used to alter the activity of Wnt signal. An infection adenoviral vector expressing short hairpin RNA to NOX4 (NOX4 shRNA) was used to knock down NOX4 expression in BEAS-2B cells. Western blotting was performed to access the expression of Wnt3a, active-β-catenin (ABC), transcription factor 4 (TCF4), cyclin D1 and NOX4 proteins in lung tissues and human lung epithelial cells. CCK-8 assay was used to determine the effects of silican. Conclusion Blocking Wnt/-catenin signal and down-regulating NOX4 expression inhibit the proliferation of lung epithelial cells and the damage repair of lung epithelial cells induced by the silica exposure.Objective To investigate the effect of progranulin (PGRN) on the invasion and migration of mouse breast cancer 4T1 cells and its mechanism. Methods After treated with PGRN (1 μg/mL) for 24 hours, the invasion ability of breast cancer 4T1 cells was detected by TranswellTM invasion assay, the migration ability was detected by scratch test, and the epithelial cadherin (E-cadherin), vimentin mRNA expression was detected by real-time fluorescent quantitative PCR. Western blot assay was used to detect the expression
