https://www.selleckchem.com/products/Sunitinib-Malate-(Sutent).html We aimed to investigate the role of the miR-29b and its effect on TGF-β3 pathway in vascular and valvular calcification in a rat model of calcific aortic valve diseases (CAVD). A rat model of CAVD was established by administration of warfarin plus vitamin K. The expression levels of miR-29b, osteogenic markers and other genes were determined by qRT-PCR, Western blot and/or immunofluorescence and immunohistochemistry. The calcium content and alkaline phosphatase (ALP) activity were measured. The calcium content, ALP activity and osteogenic markers levels in calcified aorta and aortic valve were augmented compared to controls. The expression of miR-29b, p-Smad3, and Wnt3 and β-catenin was significantly up-regulated, whereas TGF-β3 was markedly down-regulated. However, compared with the CAVD model group, the calcium content and ALP activity in rats treated with antagomiR-29b were significantly decreased, and antagomiR-29b administration reversed the effects of CAVD model on the expression of miR-29b and osteogenic markers. Inhibition of miR-29b in CAVD rats prevented from vascular and valvular calcification and induced TGF-β3 expression, suggesting that the miR-29b/TGF-β3 axis may play a regulatory role in the pathogenesis of vascular and valvular calcification and could play a significant role in the treatment of CAVD and other cardiovascular diseases.Standardization of data and models facilitates effective communication, especially in computational systems biology. However, both the development and consistent use of standards and resources remain challenging. As a result, the amount, quality, and format of the information contained within systems biology models are not consistent and therefore present challenges for widespread use and communication. Here, we focused on these standards, resources, and challenges in the field of constraint-based metabolic modeling by conducting a community-wide survey.
