Dual activation of Hedgehog and Wnt/β-catenin signaling pathway caused by downregulation of SUFU targeted by miRNA-150 in human gastric cancer.

Aging (Albany NY) 2021 Apr 12;13. Epub 2021 Apr 12.

Guangdong Key Laboratory for Genome Stability and Disease Prevention, Department of Pathology, Shenzhen University School of Medicine, Shenzhen 518060, Guangdong, P.R. China.

Mounting evidence has shown that miRNA-150 expression is upregulated in gastric cancer (GC) and is associated with gastric carcinogenesis, but the underlying oncogenic mechanism remains elusive. Here, we discovered that miRNA-150 targets the tumor suppressor SUFU to promote cell proliferation, migration, and the epithelial-mesenchymal transition (EMT) via the dual activation of Hedgehog (Hh) and Wnt signaling. MiRNA-150 was highly expressed in GC tissues and cell lines, and the level of this miRNA was negatively related to that of SUFU. Read More

Evolution of sexual development and sexual dimorphism in insects.

Curr Opin Genet Dev 2021 Apr 10;69:129-139. Epub 2021 Apr 10.

Department of Evolution and Ecology, University of California, One Shields Ave, Davis, CA, 95616, USA.

Most animal species consist of two distinct sexes. At the morphological, physiological, and behavioral levels the differences between males and females are numerous and dramatic, yet at the genomic level they are often slight or absent. This disconnect is overcome because simple genetic differences or environmental signals are able to direct the sex-specific expression of a shared genome. Read More

Tumor necrosis factor-alpha and interferon-gamma induce inflammasome-mediated corneal endothelial cell death.

Exp Eye Res 2021 Apr 10:108574. Epub 2021 Apr 10.

Department of Ophthalmology, Bascom Palmer Eye Institute, University of Miami Miller School of Medicine, Miami, FL, USA; Interdisciplinary Stem Cell Institute, University of Miami Miller School of Medicine, Miami, FL, USA.

Purpose: Chronic corneal endothelial cell (CEC) loss results in corneal edema and vision loss in conditions such as pseudophakic bullous keratopathy (PBK), Fuchs' dystrophy, and corneal graft failure. Low CEC density has been associated with an elevation of intraocular pro-inflammatory cytokines such as tumor necrosis factor (TNF)-α and interferon (INF)-γ. These cytokines are capable of triggering pyroptosis, a programmed cell death mechanism mediated by the inflammasome, prompting the activation of the pro-inflammatory cytokine interleukin (IL)-1β, the perpetuation of inflammation, and subsequent damage of corneal endothelial tissue.
