PAX6/CXCL14 regulatory axis promotes the repair of corneal injury by enhancing corneal epithelial cell proliferation.

Background: Corneal injuries, often leading to severe vision loss or blindness, have traditionally been treated with the belief that limbal stem cells (LSCs) are essential for repair and homeostasis, while central corneal epithelial cells (CCECs) were thought incapable of such repair. However, our research reveals that CCECs can fully heal and maintain the homeostasis of injured corneas in rats, even without LSCs. We discovered that CXCL14, under PAX6's influence, significantly boosts the stemness, proliferation, and migration of CCECs, facilitating corneal wound healing and homeostasis.

Changes in Corneal Morphology with Age in Asian Population: A Multicenter Study of 30,618 Cases.

Introduction: To evaluate normal reference ranges for corneal morphological parameters and investigate age-related changes in these parameters in Asian subjects with healthy eyes in order to provide reference data for preoperative evaluation of corneal refractive surgery and the early differential diagnosis of subclinical and asymptomatic keratoconus.

Methods: This cross-sectional, multicenter, observational study was conducted in five provinces of China, from January 2014 through October 2019. It is a retrospective analysis.

Distribution and Trends in Corneal Thickness Parameters in a Large Population-Based Multicenter Study of Young Chinese Adults.

Purpose: The purpose of this study was to characterize corneal thickness from multiple regions and determine accurate reference values in young adults for diagnosis and treatment.

Methods: This cross-sectional observational study was conducted from January 2008 through October 2016 using examiner-blinded clinical measurements and included 37,375 healthy eyes from young adults who exhibited normal corneal morphology, had no history of eye surgery or trauma, had stopped wearing soft contact lenses for ≥2 weeks (rigid contact lenses for ≥4 weeks), and had undergone topographies of both eyes on same day. Keratoconus and subclinical keratoconus were excluded.

MiR-497 Suppresses YAP1 and Inhibits Tumor Growth in Non-Small Cell Lung Cancer.

Background/aims: To investigate the expression, clinical significance and the cellular effects of miR-497 in non-small cell lung cancer (NSCLC).

Methods: NSCLC cells were transiently transfected with miR-497 mimics or siRNA to up-regulate or down-regulate expression. Quantitative real-time PCR (qRT-PCR) was used to detect the mRNA level of miR-497.

Wnt2 promotes non-small cell lung cancer progression by activating WNT/β-catenin pathway.

Background: Wnt2 is overexpressed and able to promote tumorigenesis in many types of cancer. However, its expression and role in lung cancer has not been well clarified yet. In this study, we aims to investigate the expression pattern, clinical significance and the underlying molecular mechanism of Wnt2 in non-small lung cancer (NSCLC).

Biocompatibility of helicoidal multilamellar arginine-glycine-aspartic acid-functionalized silk biomaterials in a rabbit corneal model.

Silk proteins represent a unique choice in the selection of biomaterials that can be used for corneal tissue engineering and regenerative medical applications. We implanted helicoidal multilamellar arginine-glycine-aspartic acid-functionalized silk biomaterials into the corneal stroma of rabbits, and evaluated its biocompatibility. The corneal tissue was examined after routine hematoxylin-eosin staining, immunofluorescence for collagen I and III, and fibronectin, and scanning electron microscopy.
