Dact1 involvement in the cytoskeletal arrangement of cardiomyocytes in atrial fibrillation by regulating cx43

Abstract Objective: To determine the role of the dishevelled binding antagonist of beta catenin 1 (DACT1) in the cytoskeletal arrangement of cardiomyocytes in atrial fibrillation (AF). Methods: The DACT1 expression and its associations with the degree of fibrosis and β-catenin in valvular disease ...

The liver injury following ischemia and reperfusion is worse in experimental knockout heterozygote mouse model for expression of connexin 43

Acta cir. bras; 34 (10), 2019
Abstract Purpose: To evaluate that Connexin (Cx43) plays a role in lesions after hepatic ischemia/reperfusion (IR) injury. Methods: We use Cx43 deficient model (heterozygotes mice) and compared to a wild group. The groups underwent 1 hour ischemia and 24 hours reperfusion. The heterozygote genotype was...

Gestational Protein Restriction Increases Cardiac Connexin 43 mRNA levels in male adult rat offspring

Arq. bras. cardiol; 109 (1), 2017
Abstract Background: The dietary limitation during pregnancy influences the growth and development of the fetus and offspring and their health into adult life. The mechanisms underlying the adverse effects of gestational protein restriction (GPR) in the development of the offspring hearts are not well u...

The role of under-investigated connexins in musculoskeletal tissue: a brief review with emphasis on bone tissue

Actual. osteol; 13 (1), 2017
Connexins (Cxs) are a family of transmembrane proteins that form gap junctions and hemi-channels, which mediate cell-cell communication between neighboring cells and the respective extracellular milieu in different tissues. Most tissues and cell types throughout the body express one or more Cx proteins, ...

β-ARRESTIN/CONNEXIN 43 (Cx43) complex anchors ERKS outside the nucleus: a prerequisite for bisphosphonate antiapoptotic effect mediated by Cx43/ERK in osteocytes

Actual. osteol; 12 (1), 2016
Bisphosphonates (BPs) anti-fracture efficacy may be due in part to inhibition of osteocyte apoptosis. This effect requires opening of connexin (Cx) 43 hemichannels and phosphorylation of the extracellular signal regulated kinases (ERKs). However, unlike ERK activation by other stimuli, the Cx43/ERK pathw...

Beta-caroteno e vitamina A modulam a proliferação de células ovais e a expressão gênica para conexina 43 em modelo in vivo de diferenciação celular hepática

Avaliou-se os efeitos do ß-caroteno e da vitamina A sobre o processo de proliferação de células ovais em modelo de diferenciação celular hepática. Para tanto, ratos machos Wistar foram tratados com ß-caroteno (grupo BC - 70 mg/kg de peso corpóreo [pc], vitamina A (grupo VA - 10 mg/kg pc) ou óle...
