چکیده مقاله:

Background: Several studies have shown that leukemia inhibitory factor (LIF) is one of the most important cytokinesparticipating in the process of embryo implantation and pregnancy, while, the role of this factor on vascular endothelialfactor-A (VEGF-A), as one of the most important angiogenic factor, has not been fully investigated yet. The aimof this study was to evaluate the effect of LIF on gene expression of VEGF in the choriocarcinoma cells (JEG-3).Materials and Methods: In this experimental study, JEG-3 choriocarcinoma cells were treated with different concentrationsof LIF (1, 10, and 50 ng) for 6, 12, 24, 48 and 72 hours. Expression of VEGF was analyzed by real-time PCR.Delta CTs were subjected to one-way analysis of variance (ANOVA) and a post hoc Tukey’s test by SPSS version 25.0software for data analyzing.Results: In the stimulated cells, different concentrations of LIF caused significant decrease of VEGF gene expression(P<0.05) at 12, 24 and 48 hours. In contrast, it was increased after 72 hours (P<0.001). Analysis of data after 6hours also showed that level of VEGF gene expression was significantly decreased by increasing LIF concentration(P<0.001).Conclusion: Expression level of VEGF gene was decreased in trophoblast cells (except after 72 hours) under theeffect of different concentrations of LIF in a time-dependent manner. So, this study showed that further studies areneeded to determine the effect of LIF on other angiogenic factors in trophoblast cells.

Vascular Endothelial Growth Factor Production is Regulated by Gene Polymorphisms

Background: Vascular endothelial growth factor (VEGF) has a key role in angiogene-sis and in transplantation. The level of VEGF is related to the differences in the DNA sequence of its promoter region. Objectives: In this study, the association between the combination of VEGF –1154 G and –2578 C alleles and VEGF production by LPS-stimulated PBMCs was investigated. In addition; the relationship ...
