Total- and phospho-ERK1/2 levels were determined in western blot.Results Tβ4 enhanced HCEC proliferation and migration in a dose- and time-dependent manner. Moreover, these functions were related to increased extracellular ATP levels, intracellular Ca2+ influx, and ERK1/2 phosphorylation. Tβ4-mediated HCEC migration was inhibited by specific P2X7 purinergic receptor antagonists suggesting the role of this receptor in Tβ4-mediated human corneal epithelial cell migration.Conclusions These results suggest that Tβ4-mediated HCEC proliferation and migration are associated with increased ATP levels, P2X7 R-mediated Ca2+ influx, and the ERK1/2 signaling pathway. This study begins to describe the mechanisms for Tβ4-mediated corneal healing and regeneration.Background Non-rheumatic valvular heart diseases (NRVDs) are common; however, no studies have estimated their global or national burden. As part of the Global Burden of Disease (GBD) 2017 study, mortality, prevalence, and disability-adjusted life years (DALYs) for calcific aortic valve disease (CAVD), degenerative mitral valve disease (DMVD), and other NRVD were estimated for 195 countries and territories from 1990 to 2017. Methods Vital registration data, epidemiological survey data, and administrative hospital data were used to estimate disease burden using the GBD modeling framework, which ensures comparability across locations. Geospatial statistical methods were used to estimates disease for all countries, as data on NRVD are extremely limited for some regions of the world, such as sub-Saharan Africa and South Asia. Results accounted for estimated level of disease severity as well as the estimated availability of valve repair or replacement procedures. DALYs and other measures of health-related burden werden among older adults. Efforts to better understand modifiable risk factors and improve access to valv
