Inhibition of Retinal Neovascularization by BEZ235: Targeting the Akt/4EBP1/Cyclin D1 Pathway in Endothelial Cells.
Invest Ophthalmol Vis Sci
January 2025
Institute of Ophthalmology, School of Medicine, Jinan University, Guangzhou, China.
Purpose: To investigate the therapeutic efficacy of BEZ235, a dual PI3K/mTOR inhibitor, in suppressing pathological neovascularization in an oxygen-induced retinopathy (OIR) mouse model and explore the role of cyclin D1 in endothelial cell cycle regulation.
Methods: Single-cell RNA sequencing was performed to analyze gene expression and cell-cycle alterations in retinal endothelial cells under normoxic and OIR conditions. The effects of BEZ235 on human umbilical vein endothelial cells (HUVECs) and human retinal microvascular endothelial cells (HRMECs) were evaluated by assessing cell viability, cell-cycle progression, proliferation, migration, and tube formation.

Brain network dynamics have been extensively explored in patients with subjective cognitive decline (SCD). However, these studies are susceptible to individual differences, scanning parameters, and other confounding factors. Therefore, how to reveal subtle SCD-related subtle changes remains unclear.

Our study aimed to investigate the factors associated with residual cavernous sinus extra-axial cavernous hemangiomas (ECHs) progression after surgery. This retrospective study consecutively included patients of cavernous sinus ECHs with incomplete lesion resection from February 2012 to January 2024. The progression of the lesions was defined as new lesions or a growth of residual lesion (≥ 10% increase in volume).

Endometrial cancer (EC) is the second most frequent gynecological malignancy and the sixth most common women's cancer worldwide. EC incidence rate is increasing rapidly. Apart from the classical, we should consider angiogenesis and hypoxia-related genes as a reason for EC manifestation and progression.

Background: Wolbachia is an endosymbiont bacterium known to stimulate host immunity against arboviruses and protozoa. Côte d'Ivoire is in a malaria-endemic region, and has experienced several dengue epidemics in recent decades as well. In order to help reduce the transmission of pathogens by mosquito vectors, we studied the prevalence of Wolbachia and the distribution of Cytoplasmic incompatibility factors (Cif) genes in different mosquito species caught in the wild in Cote d'Ivoire.
