(Submitter supplied) Mutations of the RNA-granule component TDRD7 (OMIM: 611258) cause pediatric cataract in humans. Here, we applied an integrated approach to elucidate the molecular pathology of cataract in Tdrd7 targeted-knockout (Tdrd7-/-) mice. Tdrd7-/- animals precipitously develop lens fiber cell abnormalities early in life, suggesting a global-level breakdown/mis-regulation of key cellular processes. High-throughput RNA-sequencing followed by iSyTE-integrated bioinformatics-based analysis identified the molecular chaperone and cytoskeletal-modulator, HSPB1 (HSP27), among the high-priority down-regulated candidates in Tdrd7-/- lens. more...

(Submitter supplied) Mutations/deficiency of TDRD7, which encodes a tudor domain containing protein involved in post-transcriptional gene expression control, causes early-onset cataract in humans and animal models. While Tdrd7 is implicated in the control of key lens mRNAs, the impact of Tdrd7 deficiency on microRNAs (miRNAs), and how this contributes to cataracts, is undefined. Here, we address this critical knowledge-gap by investigating Tdrd7-targeted knockout (Tdrd7-/-) mice that exhibit fully penetrant juvenile cataracts. more...

(Submitter supplied) Analysis of Tdrd7 deficiency in mouse lens epithelial-derived cell line at gene expression level. The hypothesis tested was that Tdrd7 is involved in post-transcriptional control of gene expression in the lens. Results provide evidence for differential regulation of genes involved in lens homeostasis and cataract formation in the absence of Tdrd7. In eukaryotic cells, cytoplasmic RNA granules (RGs) function in the post-transcriptional control of gene expression. more...

(Submitter supplied) Although majority of the genes linked to pediatric cataract exhibit lens fiber cell-enriched expression, our understanding of gene regulation in these cells is limited to function of just eight transcription factors and largely in the context of crystallins. Here, we identify small Maf transcription factors MafG and MafK as regulators of several non-crystallin human cataract genes in fiber cells and establish their significance to cataract. more...

To gain insight into gene expression changes underlying these lens defects, microarray comparison was performed for lenses obtained from wild-type and Celf1 conditional deletion mutant mice.

(Submitter supplied) We applied previously established in silico whole-embryo body (WB)-subtraction-based approach to identify “lens-enriched” genes. These new RNA-seq datasets on embryonic stages E10.5, E12.5, E14.5 and E16.5 confirmed high expression of established cataract-linked genes and identified several new potential regulators in the lens. Finally, we present lens stage-specific UCSC Genome Brower annotation-tracks; these are publicly accessible through iSyTE (https://research.bioinformatics.udel.edu/iSyTE/) and enable a user-friendly visualization of lens gene expression/enrichment to help prioritize genes from high-throughput data from cataract cases.

(Submitter supplied) The Shumiya cataract rat (SCR) is a model for hereditary cataract. Two-third of these rats develop lens opacity within 10-11-weeks. Onset of cataract is attributed to the synergetic effect of lanosterol synthase (Lss) and farnesyl-diphosphate farnesyltransferase 1 (Fdft1) mutant alleles that lead to cholesterol deficiency in the lenses, which in turn adversely affects lens biology including the growth and differentiation of lens epithelial cells (LECs). more...

(Submitter supplied) Genetic variations in ephrin type-A receptor 2 (EPHA2) have been associated with inherited and age-related forms of cataract in humans. Here we have characterized the eye lens phenotype and transcript profile of germline Epha2 knock-in mutant mice homozygous for either a missense variant associated with age-related cataract in humans (Epha2-Q722) or a novel insertion-deletion mutation (Epha2-indel722) that were both located within the tyrosine-kinase domain of EPHA2. more...

(Submitter supplied) Purpose: While the bioinformatics gene-discovery tool iSyTE (integrated Systems Tool for Eye gene discovery) has proved effective in identifying new cataract-linked genes, it primarily depended on lens-enriched expression of just three wild-type mouse embryonic stages. To increase iSyTE’s efficacy, a broad range of embryonic (E) and postnatal (P) lens microarray datasets from wild-type and specific gene-perturbation mutant mice were analyzed and a new web-interface was developed for their effective access and downstream-analysis. more...

(Submitter supplied) The placental renin-angiotensin system (RAS) is important for placentation. RAS expression is greatest in early gestation. This may be due (in part) to suppression of miRNAs that target the placental RAS, but this has never been explored. In this study, human placental miRNAs were measured at 10–11 (early), 14–18 (mid), and 38–40 (term) weeks gestation, as well as in placentae from women with early- or late-onset preeclampsia (n=4/group), using an Agilent miRNA microarray (V19). more...
