BACKGROUND During liver injury, hepatic stellate cells (HSCs) can undergo activation and transform into alpha-smooth muscle actin (αSMA)-expressing contractile myofibroblast-like cells, leading to deposition of excessive scar matrix. We have recently demonstrated that depletion of adenosine deaminase acting on double-stranded RNA (ADAR1) from mouse hepatocytes leads to HSC activation and induct...
Several studies have established an association between diabetes and alterations in bone metabolism; however, the underlying mechanism is not well established. Although zinc is recognized as a potential preventive agent against diabetes-induced bone loss, there is no evidence demonstrating its effect in chronic diabetic conditions. This study evaluated the effects of zinc supplementation in a c...
The domestic pig is an important "dual purpose" animal model for agricultural and biomedical applications. There is an emerging consensus in the biomedical community for the use of large animal models such as pigs to either serve as an alternative, or complement investigations from the mouse. However, the use of pig has not proven popular due to technical difficulties and time required in gener...
Degradation of type I collagen, the most abundant collagen, is initiated by collagenase cleavage at a highly conserved site between Gly775 and Ile776 of the alpha 1 (I) chain. Mutations at or around this site render type I collagen resistant to collagenase digestion in vitro. We show here that mice carrying a collagenase-resistant mutant Col1a-1 transgene die late in embryo-genesis, ascribable ...
CEP hypertrophy is one of the characteristics of intervertebral disc degeneration (IDD). LIG exerts a protective effect on IDD in animal model. The effect of LIG on CEP hypertrophy is further investigated in the present study. Cells were isolated from hypertrophic samples obtained from patients during vertebral fusion surgery. Cellular proliferation and the expression of type I collagen (Col I)...
Abnormal remodeling of atherosclerotic plaques can lead to rupture, acute myocardial infarction, and death. Enhancement of plaque extracellular matrix (ECM) may improve plaque morphology and stabilize lesions. Here, we demonstrate that chronic administration of LNA-miR-29 into an atherosclerotic mouse model improves indices of plaque morphology. This occurs due to upregulation of miR-29 target ...
BACKGROUND Nonalcoholic fatty liver disease (NAFLD) is a major public health burden in western societies. The progressive form of NAFLD, nonalcoholic steatohepatitis (NASH), is characterized by hepatosteatosis, inflammation, oxidative stress, and hepatic damage that can progress to fibrosis and cirrhosis; risk factors for hepatocellular carcinoma. Given the scope of NASH, validating treatment p...
IntRoductIon Osteogenesis imperfecta (OI), also known as brittle bone disease or Lobstein syndrome, is characterized by blue or gray sclerae, variable short stature, dentinogenesis imperfecta, hearing loss, and recurrent fractures. Based on clinical, genetic, and radiological features, Sillence et al.[1] classified the OI into four subtypes including type I: Mild, common, with blue sclera; type...
Evidence has indicated that mesenchymal stem cells (MSCs) harvested with the Reamer/Irrigator/Aspirator (RIA) procedure exhibited an improved osteogenic differentiation capability compared with MSCs obtained by bone marrow aspiration from the iliac crest. In the present study, we hypothesized that the harvest procedure indeed influences the osteogenic activity of human MSCs more than the tissue...
objective(s):to study the effect of low-frequency vibration on bone marrow stromal cell differentiation and potential bone repair in vivo. materials and methods:forty new zealand rabbits were randomly divided into five groups with eight rabbits in each group. for each group, bone defects were generated in the left humerus of four rabbits, and in the right humerus of the other four rabbits. to t...
