ACS Omega

April 2024

Tianjin Key Laboratory of Retinal Functions and Diseases, Tianjin Branch of National Clinical Research Center for Ocular Disease, Eye Institute and School of Optometry, Tianjin Medical University Eye Hospital, Tianjin 300384, China.

Article Synopsis
  • Idiopathic uveitis (IU) and Vogt-Koyanagi-Harada (VKH) syndrome are types of eye inflammation with unclear underlying mechanisms, prompting proteomic analysis of aqueous humor (AH) to identify potential biomarkers.
  • In this study, researchers analyzed 44 AH samples and found 557 proteins, revealing distinct proteomic profiles for IU and VKH compared to controls, with indications of inflammation and innate immune activation.
  • Using the XGBoost machine learning algorithm, important biomarkers like transferrin and complement factor B were identified, leading to a classification decision tree for improved diagnosis and understanding of these conditions.

Exp Eye Res

June 2024

Tianjin Key Laboratory of Retinal Functions and Diseases, Tianjin Branch of National Clinical Research Center for Ocular Disease, Eye Institute and School of Optometry, Tianjin Medical University Eye Hospital, Tianjin, China. Electronic address:

Pseudoexfoliation syndrome (PEX) is characterized by the deposition of fibrous pseudoexfoliation material (PEXM) in the eye, and secondary glaucoma associated with this syndrome has a faster and more severe clinical course. The incidence of PEX and pseudoexfoliative glaucoma (PEXG) exhibits ethnic clustering; however, few proteomic studies related to PEX and PEXG have been conducted in Asian populations. Therefore, we aimed to conduct proteomic analysis on the aqueous humor (AH) obtained from Uyghur patients with cataracts, those with PEX and cataracts, and those with PEXG and cataracts to better understand the molecular mechanisms of the disease and identify its potential biomarkers.

Article Synopsis
  • The study investigates the changes in intraretinal hyper-reflective foci (IHRF) over two years in patients with intermediate age-related macular degeneration (AMD) using optical coherence tomography (OCT).
  • It found a significant increase in the average number of IHRF per eye after 24 months, with most eyes showing an increase in these foci.
  • The results suggest that IHRF predominantly occur in the outer retinal layers and indicate a need for further research on their role in AMD progression.

Retinitis pigmentosa (RP) is a degenerative disease, caused by genetic mutations that lead to a loss in photoreceptors. For research on RP, rd10 mice, which carry mutations in the phosphodiesterase (PDE) gene, exhibit degenerative patterns comparable to those of patients with RP, making them an ideal model for investigating potential treatments. Although numerous studies have reported the potential of biochemical drugs, gene correction, and stem cell transplantation in decelerating rd10 retinal degeneration, a comprehensive review of these studies has yet to be conducted.

Article Synopsis
  • This study explored how optic disc shape, the length of the eyeball (axial length), and the arrangement of retinal blood vessels are related in the healthy eyes of young adults.
  • Researchers used advanced imaging techniques and automated software to analyze various factors such as optic disc tilt, rotation, and blood vessel density, finding that longer axial lengths result in more tilted and rotated optic discs.
  • The findings suggest that optic disc morphology impacts the distribution of retinal vessel density, highlighting the importance of considering these factors when studying eyes with myopia.

Pancreatic cancer (PC) is the most frequently occurring cancer, with few effective treatments and a 5-year survival rate of only about 11%. It is characterized by stiff interstitium and pressure on blood vessels, leading to an increased glycolytic metabolism. PFKFB3 plays an important role in glycolysis, and its products (fructose-2,6-bisphosphate), which are allosteric PFK1 activators, limit the glycolytic rate.
