METHODS: Rabbit corneal stromal cells (RCSCs) were isolated and divided into […]
Hypoxia- and mechanical stress-induced upregulation of mitochondrial HSP60 is associated with phenotypic switching of pulmonary arterial smooth muscle cells
Cell Stress Chaperones. 2025 Jul 2:100089. doi: 10.1016/j.cstres.2025.100089. Online ahead of print. ABSTRACT BACKGROUND: Switching from a contractile to a synthetic phenotype of pulmonary arterial smooth muscle cells (PASMCs) is known to play a crucial role in pulmonary arterial hypertension (PAH). We investigated how hypoxia and mechanical stress mediate the phenotypic switching of PASMCs. METHODS: […]
Preliminary insights into serum metabolomics in atrophic myopic maculopathy: potential link to fatty acid metabolism dysregulation
BMC Ophthalmol. 2025 Jul 4;25(1):392. doi: 10.1186/s12886-025-04220-7. ABSTRACT INTRODUCTION: Atrophic myopic maculopathy (AMM) causes irreversible and progressive visual impairment. Metabolomics offers a valuable opportunity for exploring the pathological mechanisms of AMM and identifying potential therapeutic targets. This study compared serum metabolite profiles between patients with high myopia with and without AMM. METHODS: This case-control study […]
Comparative mitochondrial genome and phylogenetic analysis of malaria mosquitoes Anopheles hyrcanus and Anopheles messeae
Sci Rep. 2025 Jul 4;15(1):23959. doi: 10.1038/s41598-025-09815-0. ABSTRACT Anopheles mosquitoes serve as a significant vector for the transmission of malaria and arboviruses holding great medical importance, but their phylogenetic relationships have not yet been clearly elucidated. This study was the first to sequence and analyze the mitochondrial genomic features of An. hyrcanus and An. messeae, […]
Mechanistic Study of the Novel Peroxidase Mimetic DhHP-6 in Metabolic Cataracts
Free Radic Biol Med. 2025 Jul 2:S0891-5849(25)00805-6. doi: 10.1016/j.freeradbiomed.2025.07.001. Online ahead of print. ABSTRACT Metabolic disorders such as diabetes and high-galactose often induce oxidative damage and mitochondrial dysfunction in the lens, leading to metabolic cataracts. Although surgical intervention remains the primary treatment, its associated risks and complications underscore the need for pharmacological alternatives with multifaceted […]
SHMT2 overexpression improves glaucoma by enhancing mitophagy in retinal ganglion cells through promoting the phospho of PINK1
Diagn Pathol. 2025 Jul 2;20(1):79. doi: 10.1186/s13000-025-01675-6. ABSTRACT BACKGROUND: Glaucoma is a major eye disease that causes blindness. The loss of retinal ganglion cells (RGCs) due to mitophagy impairment is a key driver of glaucoma. SHMT2 depletion leads to an increase in reactive oxygen species (ROS), but its role in regulating mitophagy remains unclear. This […]
Bi-allelic loss-of-function variants in POC5 cause a syndromic retinal, endocrine and neuromuscular ciliopathy
Genet Med. 2025 Jun 28:101513. doi: 10.1016/j.gim.2025.101513. Online ahead of print. ABSTRACT PURPOSE: A homozygous loss-of-function (LoF) variant in POC5 centriolar protein (POC5) was previously described in an individual with retinitis pigmentosa. We identified POC5 variants in twelve probands with a syndromic phenotype. We aim to define the phenotype spectrum and molecular mechanism associated with […]
Targeting oxidative stress in diabetic retinopathy: mechanisms, pathology, and novel treatment approaches
Front Immunol. 2025 Jun 16;16:1571576. doi: 10.3389/fimmu.2025.1571576. eCollection 2025. ABSTRACT Diabetic retinopathy (DR) is a common and severe microvascular complication of diabetes, leading to vision impairment and blindness, particularly in working-age adults. Oxidative stress plays a central role in the pathogenesis of DR, with excessive reactive oxygen species (ROS) damaging retinal tissues, including blood vessels […]
