The effects of basic fibroblast growth factor (bFGF) on osteogenic differentiation in-vivo were investigated using a rat bone marrow ablation model. bFGF was infused directly into rat femora for 6 days after bone marrow ablation. The contralateral femur was infused with vehicle only and used as control. Bone formation was induced in the rat femoral cavity, and the gene expression of osteoblast markers was examined. Treatment with bFGF at 50 and 100 ng/day significantly enhanced the mRNA levels of osteopontin compared with the levels in the control leg, with increases of 25% and 24%, respectively. In contrast, bFGF infusion at 50 ng/day provoked a significant (nearly 20%) inhibition of expression for type I collagen. Infusion of bFGF at a higher dose exhibited an inhibitory tendency for bFGF action on gene expression. There were no significant changes in alkaline phosphatase and osteocalcin mRNA levels in response to any dose of bFGF. The findings presented here suggest that bFGF modulates osteogenic differentiation in-vivo and may play an important role in the process of bone remodeling.

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.

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.

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.
