Analysis of the Dynamic Expression of the SMAD Family in the Periosteum During Guided Bone Regeneration.
Objective: The aim of this study was to investigate the dynamic expression of the SMAD family during guided bone regeneration for the reconstruction of cranio-maxillofacial bone defects.
Methods: A swine model of guided bone regeneration was established with one side of the rib as the trauma group and the contralateral as control group. Periosteal and regenerative tissue specimens were harvested at 9 time points in the early, middle, and late phases, and were subjected to gene sequencing and tissue staining. Expression data of each SMAD family were extracted for further analysis, in which the correlation of the expression of the respective members within and between groups and at different time points was analyzed.
Results: The expression of individual members of the SMAD family fluctuates greatly, especially during the first month. The SMAD3 and SMAD4 genes were the most highly expressed. The foldchange value of SMAD6 was the largest and remained above 1.5 throughout the process. The dynamic expression levels of SMAD2, SMAD4, SMAD5, SMAD6, and SMAD9 showed a significant positive correlation in both groups. The expression levels of each gene showed a positive correlation with other SMAD genes. Tissue staining showed that the overall contour of the regenerated bone tissue was basically formed within the first 1 month.
Conclusion: The first month of guided bone regeneration is a critical period for bone regeneration and is an important period for the SMAD family to play a role. The SMAD6 may play an important role in the whole process of guided bone regeneration.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
