Lower limbs venous insufficiency refers to a wide variety of venous disorders grouped by the term of chronic venous disease (CVD). Hemodynamic and hormonal changes related to pregnancy period, may promote the development of CVD affecting approximately 1 in 3 women. It has been shown that the presence of this condition is associated with damage and placental suffering. Thus, taking IGF-1/PAPP-A/STC-2, inflammatory cytokines production, PI3K/Akt and Wnt/ β-catenin pathways as a part of the alterations that occurs in the placenta due to CVD, the aim of this study will be to examine the main components of these pathways. Genic and protein expression of PAPP-A, STC-2, IGF-1, IRS-4 Wnt-1, β-catenin, c-myc, Cyclin D1, IL-4/IL-6 and PI3K/Akt/mTOR pathway will be analysed through RT-qPCR and immunohistochemical techniques in women with CVD (n=62) and pregnant women without this condition (HC) (n=52). PAPP-A, IGF-1, IL-4, IL-6, IRS-4, PI3K, Akt, mTOR, Wnt-1, β-catenin, c-myc and Cyclin D1 expression were found to be increased in women with CVD, whereas STC-2 were decreased in this group, compared to non-affected women. Our study has demonstrated that IGF-1/PAPP-A/STC-2 axis, PI3K/Akt and Wnt/β-catenin pathways, along with c-myc, Cyclin D1 and inflammatory cytokines are altered in placenta women with CVD. These results extent the knowledge that CVD is associated to a placenta damage with abnormal tissue environment and cellular regulation.

妊娠期慢性静脉疾病妇女胎盘中调节细胞 IGF-1/PAPP-A/STC 和 Wnt-1/β-Catenin 经典通路增加的异常促炎和应激环境

下肢静脉功能不全是指按慢性静脉疾病 (CVD) 术语分组的多种静脉疾病。与妊娠期相关的血流动力学和激素变化可能会促进 CVD 的发展,影响大约三分之一的女性。已经表明,这种情况的存在与损伤和胎盘痛苦有关。因此,将 IGF-1/PAPP-A/STC-2、炎性细胞因子的产生、PI3K/Akt 和 Wnt/β-catenin 通路作为 CVD 胎盘中发生的改变的一部分,本研究的目的是是检查这些途径的主要组成部分。PAPP-A、STC-2、IGF-1、IRS-4 Wnt-1、β-catenin、c-myc、Cyclin D1、IL-4/IL-6 和 PI3K/Akt/mTOR 通路将通过 RT-qPCR 和免疫组织化学技术在患有 CVD 的女性(n=62)和没有这种情况的孕妇(HC)(n=52)中进行分析。发现 PAPP-A、IGF-1、IL-4、IL-6、IRS-4、PI3K、Akt、mTOR、Wnt-1、β-catenin、c-myc 和 Cyclin D1 表达在患有 CVD 的女性中增加,而与未受影响的女性相比,该组的 STC-2 减少。我们的研究表明 IGF-1/PAPP-A/STC-2 轴、PI3K/Akt 和 Wnt/β-catenin 通路以及 c-myc、细胞周期蛋白 D1 和炎性细胞因子在患有 CVD 的胎盘妇女中发生了改变。这些结果扩展了 CVD 与胎盘损伤与异常组织环境和细胞调节相关的知识。发现 c-myc 和细胞周期蛋白 D1 表达在患有 CVD 的女性中增加,而与未受影响的女性相比,该组中的 STC-2 表达降低。我们的研究表明 IGF-1/PAPP-A/STC-2 轴、PI3K/Akt 和 Wnt/β-catenin 通路以及 c-myc、细胞周期蛋白 D1 和炎性细胞因子在患有 CVD 的胎盘妇女中发生了改变。这些结果扩展了 CVD 与胎盘损伤与异常组织环境和细胞调节相关的知识。发现 c-myc 和细胞周期蛋白 D1 表达在患有 CVD 的女性中增加,而与未受影响的女性相比,该组中的 STC-2 表达降低。我们的研究表明 IGF-1/PAPP-A/STC-2 轴、PI3K/Akt 和 Wnt/β-catenin 通路以及 c-myc、细胞周期蛋白 D1 和炎性细胞因子在患有 CVD 的胎盘妇女中发生了改变。这些结果扩展了 CVD 与胎盘损伤与异常组织环境和细胞调节相关的知识。
