Abstract
Chronic venous disease (CVD) is a complex and common vascular disorder characterized by increased blood pressure and morpho-functional changes in the venous system like varicose veins. Pregnancy is one of the main risk factors for suffering from this condition. Despite the consequences of CVD during pregnancy remains to be fully understood, compelling evidence support that this condition represents an important stress for the mother and the fetus, leading to significant histopathological changes in the placenta. Tetraspanins (CD9, CD63, and CD81), ALG-2-interacting protein X (Alix), and heat-shock protein (HSP-70) are cellular components involved in multiple biological processes under homeostatic and disease conditions. Despite some studies that have evidence of their relevance in the placenta tissue and pathological pregnancies, there is limited knowledge regarding their role in pregnancy-associated CVD. In this sense, the present work aims to analyze gene and protein expression of these components in the placenta of women with CVD (n=62) in comparison to healthy women (n=52) through RT-qPCR and immunohistochemistry, respectively. Our results show an increased gene and protein expression of the different studied markers, suggesting their potential involvement in the pathological environment of the placenta of women who undergo CVD during pregnancy. In this sense, further studies should be directed to deep into the potential implications of these changes to understand the effects and consequences of this condition in maternofetal wellbeing.

Abstract
Dysfunction of the microRNA (miRNA) network has been emerging as a main regulator in ischemic stroke. Recently, studies have linked the deregulation of miR-122 to ischemic stroke. However, the specific role and molecular mechanism of miR-122 in ischemic stroke remain to be further investigated. Here, we found that miR-122 was decreased in mouse N2A neuroblastoma (N2A) cells after oxygen-glucose deprivation (OGD) and mouse brain after transient middle cerebral artery occlusion (MCAO). OGD treatment significantly increased N2A cell death and Caspase-3 activity, and decreased Bcl-2 protein expression. In addition, MCAO treatment induced severe mouse brain infarction, mitochondrial reactive oxygen species (ROS) production, and long-term neurological deficit. Gain-of-miR-122 function significantly suppressed OGD- and MCAO-induced injures in vitro and in vivo. Subsequently, miR-122 was validated to directly bind to the predicted 3'-untranslated region (3'-UTR) of FOXO3 gene, and the inhibitory effects of miR-122 on ischemic injury in vitro and in vivo were overturned by FOXO3 overexpression. Moreover, our results further revealed that miR-122-FOXO3 axis functioned via the heat shock protein 70 (HSP-70)-mediated NF-κB pathway. Collectively, our data suggest that miR-122 inhibits ischemic neuronal death through the HSP-70-dependent NF-κB pathway by targeting FOXO3. These findings raise the possibility that this regulatory net may contribute to the pathogenesis of the ischemic brain injury in stroke.
