Icariin interacts with IGFBP3 to alleviate diabetic cataract through PI3K/AKT signaling pathway.

Diabetic cataract (DC), a well-recognized complication in diabetic patients, can progress to blindness if not adequately managed, with currently limited therapeutic strategies. Icariin (ICA), a natural compound derived from Epimedium, has been demonstrated exhibiting anti-inflammatory and anti-oxidant, but its impact on diabetic cataracts remains elusive. In this study, we used both SRA01/04 cells and SD rats' model to explored the protective effects of ICA in cataract formation.

Muscone Attenuates Uveitis Through the PI3K/AKT Signaling Pathway.

Purpose: Uveitis is an immune-mediated ocular disorder that poses a significant threat to vision, particularly among young and middle-aged adults. The treatment of uveitis is complicated by the presence of the blood-retinal barrier (BRB), which restricts the passage of large molecular drugs into the eye, thus limiting effective therapeutic options. The primary objective of this study is to identify a novel therapeutic agent capable of treating uveitis and explore its underlying mechanism.

BARD1-mediated stabilization of METTL14 promotes retinal neovascularization by m6A-modifying MXD1 mRNA on a YTHDF2-dependent manner.

Retinal vascular diseases are typified by the proliferation of irregular and leaky microvessels, resulting in vision impairment. Although the etiology of retinal angiogenesis is not yet fully understood, it is evident that microglia play a pivotal role in promoting angiogenesis. In vivo, the METTL14 conditional knockout (cKO) mouse was constructed to investigate the role of METTL14 in oxygen-induced retinopathy (OIR).

Identification and validation of diagnostic genes and in insomnia-associated autoimmune uveitis.

Objective: Insomnia is increasingly recognized as a significant factor in the development of various autoimmune diseases, including autoimmune uveitis (AU). We investigated insomnia-associated genes that may contribute to AU pathogenesis and sought to identify potential biomarkers for insomnia-associated AU.

Methods: Microarray data related to insomnia and AU were downloaded from the Gene Expression Omnibus (GEO) database and analyzed.

Autophagy-mediated activation of the AIM2 inflammasome enhances M1 polarization of microglia and exacerbates retinal neovascularization.

Retinopathy of prematurity (ROP) is a retinal neovascularization (RNV) disease that is characterized by abnormal blood vessel development in the retina. Importantly, the etiology of ROP remains understudied. We re-analyzed previously published single-cell data and discovered a strong correlation between microglia and RNV diseases, particularly ROP.

A feedback loop driven by H3K9 lactylation and HDAC2 in endothelial cells regulates VEGF-induced angiogenesis.

Background: Vascular endothelial growth factor (VEGF) is one of the most powerful proangiogenic factors and plays an important role in multiple diseases. Increased glycolytic rates and lactate accumulation are associated with pathological angiogenesis.

Results: Here, we show that a feedback loop between H3K9 lactylation (H3K9la) and histone deacetylase 2 (HDAC2) in endothelial cells drives VEGF-induced angiogenesis.

YY1 Lactylation Aggravates Autoimmune Uveitis by Enhancing Microglial Functions via Inflammatory Genes.

Activated microglia in the retina are essential for the development of autoimmune uveitis. Yin-Yang 1 (YY1) is an important transcription factor that participates in multiple inflammatory and immune-mediated diseases. Here, an increased YY1 lactylation in retinal microglia within in the experimental autoimmune uveitis (EAU) group is observed.

Global lactylome reveals lactylation-dependent mechanisms underlying T17 differentiation in experimental autoimmune uveitis.

Dysregulation of CD4 T cell differentiation is linked to autoimmune diseases. Metabolic reprogramming from oxidative phosphorylation to glycolysis and accumulation of lactate are involved in this process. However, the underlying mechanisms remain unclear.

A dual-function chitosan packaging film for simultaneously monitoring and maintaining pork freshness.

Exploring food packaging films simultaneously possess freshness monitoring and maintaining can effectively tackle food safety issues. Here, we constructed a chitosan/N-doped carbon dots (CS/N-CDs) film which can monitor the freshness of pork based on pH-mediated fluorescent sensing and extend the shelf life based on the antioxidant, antibacterial and UV shielding properties. The fluorescent intensity of CS/N-CDs films increased with the increase of pork pH from 5.
