Downregulation of connexin 43 expression by high glucose reduces gap junction activity in microvascular endothelial cells.
Impairment of retinal vascular homeostasis is associated with the development and progression of diabetic retinopathy involving gap junction intercellular communication (GJIC) activity. The principal gap junction protein of intercellular communication, connexin, was investigated to determine the effects of high glucose concentrations on the expression of endothelial-specific connexins (Cx37, Cx...
متن کاملHigh glucose-induced downregulation of connexin 43 expression promotes apoptosis in microvascular endothelial cells.
PURPOSE This study aims to determine whether high glucose-induced inhibition of connexin 43 (Cx43) expression and reduced gap junction intercellular communication (GJIC) promote microvascular endothelial cell loss. METHODS To downregulate Cx43 protein expression in rat microvascular endothelial cells (RMECs), the cells were grown in high (30 mM) glucose medium for 7 days, or transfected with ...
متن کاملEndothelial connexin43 mediates acid-induced increases in pulmonary microvascular permeability.
Acid aspiration, a common cause of acute lung injury, leads to alveolar edema. Increase in lung vascular permeability underlies this pathology. To define mechanisms, isolated rat lungs were perfused with autologous blood. Hydrochloric acid and rhodamine-dextran 70 kDa (RDx70) were coinstilled into an alveolus by micropuncture. RDx70 fluorescence was used to establish the spatial distribution of...
متن کاملConnexin 43 mediates spread of Ca2+-dependent proinflammatory responses in lung capillaries.
Acute lung injury (ALI), which is associated with a mortality of 30-40%, is attributable to inflammation that develops rapidly across the lung's vast vascular surface, involving an entire lung or even both lungs. No specific mechanism explains this extensive inflammatory spread, probably because of the lack of approaches for detecting signal conduction in lung capillaries. Here, we addressed th...
متن کاملConnexin 43 expressed in endothelial cells modulates monocyte‑endothelial adhesion by regulating cell adhesion proteins.
Adhesion between circulating monocytes and vascular endothelial cells is a key initiator of atherosclerosis. In our previous studies, it was demonstrated that the expression of connexin (Cx)43 in monocytes modulates cell adhesion, however, the effects of the expression of Cx43 in endothelial cells remains to be elucidated. Therefore, the present study investigated the role of the expression of ...
