Project description:In this series the ocular primordium was microdissected from normal CD-1 (outbred) mouse embryos harvested days 8-10 post-coitus, corresponding to human development during the 3rd-4th weeks post-fertilization. The precise embryological age was ascertained by counting somite pairs to an accuracy of +/- 2 pairs per litter. Samples were pooled as follows: optic pit pooled from 48-50 embryos (6 litters) on 8 d.p.c. (4-8 somite pairs), optic vesicle pooled from 36-40 embryos (5 litters) on 9 d.p.c. (16-20 somite pairs), and optic cip pooled from 27-30 embryos (3 litters) on 10 d.p.c. (28-32 somite pairs). The common reference for this series was RNA collected from embryonic headfold microdissected on 8 d.p.c. RNA samples were collected from CD-1 rat embryos at equivalent somite stages for the headfold, optic vesicle, and opic cup.

Project description:Mutations in Peroxidasin (PXDN) cause severe inherited eye disorders in humans, such as congenital cataract, corneal opacity, and developmental glaucoma. The role of peroxidasin during eye development is poorly understood. Here we describe the first Pxdn mouse mutant which was induced by ENU (N-ethyl-N-nitrosourea) and led to a recessive phenotype. Sequence analysis of cDNA revealed a T3816A mutation resulting in a premature stop codon (Cys1272X) in the peroxidase domain. This mutation causes severe anterior segment dysgenesis and microphthalmia resembling the manifestations in patients with PXDN mutations. The proliferation and differentiation of the lens is disrupted in association with aberrant expression of transcription factor genes (Pax6 and Foxe3) in mutant eyes. Additionally, Pxdn is involved in the consolidation of the basement membrane and lens epithelium adhesion in the ocular lens. Lens material including γ-crystallin is extruded into the anterior and posterior chamber due to local loss of structural integrity of the lens capsule as a secondary damage to the anterior segment development leading to congenital ocular inflammation. Moreover, Pxdn mutants exhibited an early-onset glaucoma and progressive retinal dysgenesis. Transcriptome profiling revealed that peroxidasin affects the transcription of developmental and eye diseases-related genes at early eye development. These findings suggest that peroxidasin is necessary for cell proliferation and differentiation and for basement membrane consolidation during eye development. Our studies provide pathogenic mechanisms of PXDN mutation-induced congenital eye diseases.

Project description:Here, we presented an atlas of region resolved proteome and lipidome of mouse eye. The multiphoton microscopy-guided laser microdissection combined with in depth label-free proteomics, enable us to identify 13,536 proteins in 11 regions of mouse eye. Further integrative analysis of label-free proteome and imaging mass spectrometry (IMS), visually revealed the distinctive molecular features, including proteins, lipids, and glycans of various anatomical mouse eye regions. This work presented the panoramic eye proteome map, and served as the rich resource for eye researches in the future.

Project description:MicroRNA expression in the mouse eye.MicroRNAs (miRNAs) are key regulators of biological processes. To define miRNA function in the eye, it is essential to determine a high-resolution profile of their spatial and temporal distribution. In this report, we present the first comprehensive survey of miRNA expression in ocular tissues, using both microarray and RNA in situ hybridization (ISH) procedures. We initially determined the expression profiles of miRNAs in the retina, lens, cornea and retinal pigment epithelium of the adult mouse eye by microarray. Each tissue exhibited notably distinct miRNA enrichment patterns and cluster analysis identified groups of miRNAs that showed predominant expression in specific ocular tissues or combinations of them. Next, we performed RNA ISH for over 220 miRNAs, including those showing the highest expression levels by microarray, and generated a high-resolution expression atlas of miRNAs in the developing and adult wild-type mouse eye, which is accessible in the form of a publicly available web database. We found that 122 miRNAs displayed restricted expression domains in the eye at different developmental stages, with the majority of them expressed in one or more cell layers of the neural retina . This analysis revealed miRNAs with differential expression in ocular tissues and provided a detailed atlas of their tissue-specific distribution during development of the murine eye. The combination of the two approaches offers a valuable resource to decipher the contributions of specific miRNAs and miRNA clusters to the development of distinct ocular structures.
