Knockout of miR-184 in zebrafish leads to ocular abnormalities by elevating p21 levels.

miR-184 is one of the most abundant miRNAs expressed in the lens and corneal tissue. Mutations in the seed region of miR-184 are responsible for inherited anterior segment dysgenesis. Animal models recapitulating miR-184-related anterior segment dysgenesis are still lacking, and the molecular basis of ocular abnormalities caused by miR-184 dysfunction has not been well elucidated in vivo.

Genome-based classification of Pedobacter polysacchareus sp. nov., isolated from Antarctic soil producing exopolysaccharide.

A psychrotolerant bacterial strain, designated ZS13-49T, with strong extracellular polysaccharide synthesis ability was isolated from soil collected in Antarctica and subjected to polyphasic taxonomic and comparative genomics. Chemotaxonomic features, including fatty acids, and polar lipid profiles, support the assignment of strain ZS13-49T to the genus Pedobacter. 16S rRNA gene phylogeny demonstrates that strain ZS13-49T forms a well-supported separate branch as a sister clade to Pedobacter gandavensis LMG 31462T and is clearly separated from Pedobacter steynii DSM 19110T and Pedobacter caeni DSM 16990T.

Extracellular HSP90 promotes differentiation of lens epithelial cells to fiber cells by activating LRP1-YAP-PROX1 axis.

Capsular residual lens epithelial cells (CRLEC) undergo differentiation to fiber cells for lens regeneration or tansdifferentiation to myofibroblasts leading to posterior capsular opacification (PCO) after cataract surgery. The underlying regulatory mechanism remains unclear. Using human lens epithelial cell lines and the ex vivo cultured rat lens capsular bag model, we found that the lens epithelial cells secrete HSP90α extracellularly (eHSP90) through an autophagy-associated pathway.

Knockout of DLIC1 leads to retinal cone degeneration via disturbing Rab8 transport in zebrafish.

Retinal photoreceptors execute phototransduction functions and require an efficient system for the transport of materials (e.g. proteins and lipids) from inner segments to outer segments.

Retinitis pigmentosa 2 pathogenic mutants degrade through BAG6/HUWE1 complex.

Retinitis pigmentosa (RP) is the most common inherited retinal degenerative disease which is the major cause of vision loss. X-linked RP patients account for 5%-15% of all inherited RP cases and mutations in RP2 (Retinitis pigmentosa 2) were responsible for about 20% X-linked RP families. A majority of RP2 pathogenic mutations displayed a vulnerable protein stability and degraded rapidly through ubiquitin-proteasome system (UPS).

Biotin attenuates heat shock factor 4b transcriptional activity by lysine 444 biotinylation.

Genetic mutations in HSF4 cause congenital cataracts. HSF4 exhibits both positive and negative regulation on the transcription of heat shock and non-heat shock proteins during lens development, and its activity is regulated by posttranslational modifications. Biotin is an essential vitamin that regulates gene expression through protein biotinylation.

[Analysis of metabolite differences in skin between Clapp's Favorite and its mutant Red Clapp's Favorite through non-targeted metabolomics].

Red Clapp's Favorite is the red mutation cultivar of the pear cultivar Clapp's Favorite. Fruit color is an important feature of pear fruits, with red skin generally attracting consumers. Anthocyanin, chlorophyll, and carotenoids are the most important pigments in the color formation of fruits.

HSP90 acts as a senomorphic target in senescent retinal pigmental epithelial cells.

The senescence of retinal pigment epithelial (RPE) cells is associated with age-related macular degeneration (AMD), a leading cause of blindness in the world. HSP90 is a predominant chaperone that regulates cellular homeostasis under divergent physio-pathological conditions including senescence. However, the role of HSP90 in senescent RPE cells still remains unclear.

Deficiency of heat shock factor 4 promotes lens epithelial cell senescence through upregulating p21 expression.

Genetic mutations in heat shock factor 4 (Hsf4) is associated with both congenital and age-related cataracts. Hsf4 regulates lens development through its ability to both activate and inhibit transcription. Previous studies suggested Hsf4 is involved in modulating cellular senescence depending on p21 and p27 expression in MEF cells.

Expression of mRNAs, miRNAs, and lncRNAs in Human Trabecular Meshwork Cells Upon Mechanical Stretch.

Purpose: Intraocular pressure (IOP), the primary risk factor for primary open-angle glaucoma, is determined by resistance to aqueous outflow through the trabecular meshwork (TM). IOP homeostasis relies on TM responses to mechanical stretch. To model the effects of elevated IOP on the TM, this study sought to identify coding and non-coding RNAs differentially expressed in response to mechanical stretch.

Knockout of DNase1l1l abrogates lens denucleation process and causes cataract in zebrafish.

Removal of nuclei in lens fiber cells is required for organelle-free zone (OFZ) formation during lens development. Defect in degradation of nuclear DNA leads to cataract formation. DNase2β degrades nuclear DNA of lens fiber cells during lens differentiation in mouse.

Heat shock factor 4 regulates lysosome activity by modulating the αB-crystallin-ATP6V1A-mTOR complex in ocular lens.

Background: Germline mutations in heat shock factor 4 (HSF4) cause congenital cataracts. Previously, we have shown that HSF4 is involved in regulating lysosomal pH in mouse lens epithelial cell in vitro. However, the underlying mechanism remains unclear.

HSP90 as a novel therapeutic target for posterior capsule opacification.

Posterior capsule opacification (PCO) is a common complication of cataract surgery, resulting from a combination of proliferation, migration, epithelial-mesenchymal transition (EMT) of residual capsular epithelial cells and fibrosis of myofibroblasts. HSP90 is known to regulate the proteostasis of cells under pathophysiological conditions. The role of HSP90 in PCO formation, however, is not clear.

A novel RP2 missense mutation Q158P identified in an X-linked retinitis pigmentosa family impaired RP2 protein stability.

Retinitis pigmentosa (RP) is the most common form of inherited retinal degenerative diseases. X-linked RP accounts for nearly 15% of all RP cases. In this study, we identified a novel RP2 missense mutation Q158P in a Chinese XLRP family.

Downregulation of heat shock factor 4 transcription activity via MAPKinase phosphorylation at Serine 299.

Dysfunction of HSF4 is associated with congenital cataracts. HSF4 transcription activity is turned on and regulated by phosphorylation during early postnatal lens development. Our previous data suggested that mutation HSF4b/S299A can upregulate HSF4 transcription activity in vitro, but the biological significance of posttranslational modification on HSF4/S299 during lens development remains unclear.
