Abstract
Background & objectives: One of the functions of RNA editing is to change the RNA sequence without changing the genomic DNA sequence and changing the fate of cellular RNA. Therefore, studying the clinical application of RNA editing for targeted therapies is necessary.
Methods: All articles related to the subject of the study were searched in the Scopus,
PubMed/Medline, ISI Web of Knowledge, and Google Scholar database.
Results: The changes that occur within the RNA editing are A to I base replacement by adenosine deaminase (ADAR) on RNA and C to U replacement by the apolipoprotein B mRNA-editing enzyme, catalytic polypeptide1 (APOBEC1). Recently, the role of RNA editing in human diseases has been reported.
Conclusion: RNA editing can be used as a new strategy to identify new disease biomarkers and more personalized treatments for various diseases.

Abstract
Background: Identifying protein interactions is one of the main challenges in the fields of biostructure and molecular biology. Despite extensive progress, the exact patterns of protein-protein interactions are still unknown. The main goal of this study is to computationally evaluate the interactions of fibronectin-1 in the extracellular matrix of decellularized trachea and integrins in adipose tissue stem cells in order to provide the most accurate possible visualization of these interactions and their role in biological processes.
Methods: After decellularization of the sheep trachea through the detergent-enzyme method, histological evaluations and ultrastructure photography of the samples were done by scanning electron microscopy. Also, the simulations of fibronectin1 binding of extracellular matrix protein with integrin αvβ1 and α5β3 of stem cells derived from adipose tissue were investigated, and interaction energy analysis was applied to predict the structure of protein-protein complexes using the algorithms available in HDOCK and ClusPro servers.
Results: The findings indicated the preservation of extracellular matrix components and scaffold ultrastructure. Also, in order to find the most favorable connection states in terms of energy, some of them were reported as stable interactions among the top types of connections. This insight provides a valuable understanding of cell-matrix adhesion, migration, and signaling, with potential implications for therapeutic development.
Conclusion: The prepared scaffolds are ideal for engineering applications for which computational analysis and experimental data have been used for visualization of stable connection states with energy efficiency between fibronectin and integrin. Also, more studies on cell adhesion modeling in connection with tissue engineering science can provide a suitable field for the development of regenerative medicine in further studies.
