Abstract
Pseudoexfoliation (PXF) syndrome is an important public health concern requiring individual population level analysis. Disease prevalence differs by geographic location and ethnicity, and has environmental, demographic, genetic, and molecular risk factors have been demonstrated. Epidemiological factors that have been associated with PXF include age, sex, environmental factors, and diet. Genetic and molecular components have also been identified that are associated with PXF. Underserved populations are often understudied within scientific research, including research about eye disease such as PXF, contributing to the persistence of health disparities within these populations. In each population, PXF needs may be different, and by having research that identifies individual population needs about PXF, the resources in that population can be more efficiently utilized. Otherwise, PXF intervention and care management based only on the broadest level of understanding may continue to exacerbate health disparities in populations disproportionally burdened by PXF.

Knockdown of LOXL1 inhibits TGF-β1-induced proliferation and fibrogenesis of hepatic stellate cells by inhibition of Smad2/3 phosphorylation. Biomed Pharmacother 2018; 107:1728-1735.

Abstract
Liver fibrosis is pathological condition that seriously threatens human health. The lysyl oxidase (LOX) family has been reported to promote liver fibrosis. However, the effect of LOX-like 1 (LOXL1), a member of LOX family, on fibrogenesis of hepatic stellate cells (HSCs) remains unknown. The current study aimed to investigate the role of LOXL1 in liver fibrosis and the potential mechanism. We found that the mRNA and protein levels of LOXL1 were increased in transforming growth factor-beta 1 (TGF-β1)-stimulated human hepatic stellate cell line LX-2. Knockdown of LOXL1 inhibited the proliferation of TGF-β1-stimulated LX-2 cells. Knockdown of LOXL1 suppressed TGF-β1-induced expression of metalloproteinase type 1 (TIMP1), α-smooth muscle actin (α-SMA), and collagen type I (Col-I), as well as phosphorylation of Smad2 and Smad3 in LX-2 cells. In addition, the cell proliferation and fibrogenesis mediated by TGF-β1 stimulation and LOXL1 overexpression were abolished by knockdown of Smad2 and Smad3. Collectively, knockdown of LOXL1 suppressed cell proliferation and fibrogenesis in TGF-β1-stimulated HSCs via regulating the phosphorylation of Smad2/3.
