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.
In silico analysis of non-conventional gene targets for genetic interventions to enhance fatty acid production: a review.

Since the 1990s, fatty acids (FA) have drawn significant industrial attention due to their diverse applications creating a demand for biological systems capable of producing high FA titers. While various strategies have been explored to achieve this, many of the conventional approaches rely on extensive genetic manipulations, which often result in strain instability, thus limiting its potential to yield better FA titers. Moreover, stresses such as pH, osmotic, and oxidative imbalances generated during FA production aggravate these challenges, further limiting FA titers.

Non-alcoholic fatty liver disease (NAFLD) is a disease with various levels varying from fatty liver steatosis to acute steatosis which is non-alcoholic steatohepatitis (NASH), which can develop into hepatic failure, as well as in some conditions it can develop into hepatocellular carcinoma (HCC). In the NAFLD and NASH context, aberrant microRNA (miRNA) expression has a thorough contribution to the incidence and development of these liver disorders by influencing key biological actions, involving lipid metabolism, inflammation, and fibrosis. Dysregulated miRNAs can disrupt the balance between lipid accumulation and clearance, exacerbate inflammatory responses, and promote fibrogenesis, thus advancing the severeness of the disorder from simple steatosis to more complex NASH.

The use of cell lines as alternative models for environmental physiology studies opens a new window of possibilities and is becoming an increasingly used tool in marine research to fulfil the 3R's rule. In this study, an embryonic monoclonal stem cell line obtained from a marine teleost (gilthead seabream, Sparus aurata) was employed to assess the effects of photoperiod (light/dark cycles vs constant dark) and light spectrum (white, blue, green, blue/green and red lights) on gene expression and rhythms of cellular markers of proliferation, DNA repair, apoptosis and cellular/oxidative stress by RT-qPCR and cosinor analyses. The results obtained revealed the optimal performance of cells under blue light (LDB), with all the genes analysed showing their highest RNA expression levels and most robust daily variations/rhythms in this condition.

Background And Aim: Creeping fat (CF) in Crohn's disease (CD) is characterized by hyperplastic mesenteric adipose tissue (MAT) encasing fibrotic intestinal segments. CF exhibits disruptions in microbiota and lipid metabolism, particularly in lysophospholipids (LPC). This study aims to elucidate the impact of LPC on adipogenic differentiation of mesenchymal stem cells in CF and its effects on immune defense functions in the differentiated adipocytes.
