Cardiovascular Disease and Breast Cancer Stage at Diagnosis.
JAMA Netw Open
January 2025
Department of Epidemiology, University of Texas MD Anderson Cancer Center, Houston.
Importance: Cardiovascular disease (CVD) and cancer are the leading causes of mortality in the US. Large-scale population-based and mechanistic studies support a direct effect of CVD on accelerated tumor growth and spread, specifically in breast cancer.
Objective: To assess whether individuals presenting with advanced breast cancers are more likely to have prevalent CVD compared with those with early-stage breast cancers at the time of diagnosis.
Retinal Müller Cell-Released Exosomal MiR-92a-3p Delivers Interleukin-17A Signal by Targeting Notch-1 to Promote Diabetic Retinopathy.
Invest Ophthalmol Vis Sci
January 2025
Department of Ophthalmology, The First Affiliated Hospital of Nanjing Medical University, Nanjing, China.
Purpose: Inflammatory processes have been involved in diabetic retinopathy (DR). Interleukin (IL)-17A, a pro-inflammatory cytokine, is associated with DR occurrence and development. However, mechanisms underlying the IL-17A impact on DR need further investigations.

Invest Ophthalmol Vis Sci
January 2025
Laboratory of Anatomy of Domestic Animals, National Key Laboratory of Veterinary Public Health and Safety, College of Veterinary Medicine, China Agricultural University, Haidian, Beijing, China.
Purpose: Because chickens have excellent light perception properties, this study focused on investigating whether monochromatic light can cause photodamage in chicken retinal ganglion cells (RGCs).
Methods: Post-hatching day chickens were exposed to four different light-emitting diode light environments for five weeks, respectively, monochromatic blue light (480 nm), green light (560 nm), red light (660 nm), or white light (6000 K). The mechanisms through which monochromatic light influences the structure of the chicken retina were analyzed by detecting the morphological structure of the retina, gene and protein expression levels, and the ultrastructure of the optic nerve.
Deep Learning-Based SD-OCT Layer Segmentation Quantifies Outer Retina Changes in Patients With Biallelic RPE65 Mutations Undergoing Gene Therapy.
Invest Ophthalmol Vis Sci
January 2025
Institute for Applied Mathematics, University of Bonn, Bonn, Germany.
Purpose: To quantify outer retina structural changes and define novel biomarkers of inherited retinal degeneration associated with biallelic mutations in RPE65 (RPE65-IRD) in patients before and after subretinal gene augmentation therapy with voretigene neparvovec (Luxturna).
Methods: Application of advanced deep learning for automated retinal layer segmentation, specifically tailored for RPE65-IRD. Quantification of five novel biomarkers for the ellipsoid zone (EZ): thickness, granularity, reflectivity, and intensity.
Bayesian Phylogenetic Lineage Reconstruction with Loss of Heterozygosity Mutations Derived from Single-Cell RNA Sequencing.
Methods Mol Biol
January 2025
Allen Discovery Center for Lineage Tracing and Department of Laboratory Medicine & Pathology, University of Washington, Seattle, WA, USA.
Mutations are acquired frequently, such t`hat each cell's genome inscribes its history of cell divisions. Loss of heterozygosity (LOH) accumulates throughout the genome, offering large encoding capacity for phylogenetic inference of cell lineage.In this chapter, we demonstrate a method, using single-cell RNA sequencing, for reconstructing cell lineages from inferred LOH events in a Bayesian manner, annotating the lineage with cell phenotypes, and marking developmental time points based on X-chromosome inactivation.
