چکیده

Identification of gene expression profiles, RNA interactions, gene regulation patterns, and single nucleotide polymorphisms (SNPs) is important for determining the molecular mechanisms underlying the normal odontogenesis and the pathology of oral and dental disorders. Therefore, this in silico study aimed to identify novel proteins, RNA interactions, and deleterious SNPs related to four major genes (MSX۲, SHH, SMAD۷, TFAP۲) involved in the odontogenesis process. After pathway enrichment and gene ontology analysis, the protein-protein, microRNA (miRNA)-mRNA, and miRNA-long noncoding RNA (lncRNA) interactions and networks were determined for the selected genes using integrated bioinformatics analyses. Moreover, the potential deleterious SNPs in the selected genes were identified and finally, their validation and implications on the structure of proteins were investigated by specific bioinformatics tools. The results of this study introduced UBE۲I, RNF۱۱۱, MYBL۲, and VEGFA as novel factors that may involve in odontogenesis. It was also found that the MSX۲, SHH, and TFAP۲A are targeted by hsa-miR-۶۷۷۵-۵p, hsa-miR-۱۴۹-۳p, and hsa-miR-۴۳۲-۵p, respectively. Moreover, the hsa-miR-۱۳۴-۵p regulated the SHH and TFAP۲A gene expression. LINC۰۲۰۳۵ and C۳orf۳۵ were also introduced as important lncRNAs that may involve in competitive endogenous RNA interaction with the SHH for binding to the hsa-miR-۱۴۹-۳p. Moreover, LINC۰۰۳۱۹, interacting with the hsa-miR-۶۷۷۵-۵p, indirectly regulated the MSX۲ expression. We also identified various SNPs in the investigated genes that changed the normal structure and thus the function of their related proteins. This study, for the first time, introduces different new proteins, miRNAs, lncRNAs, and SNPs that may be important for normal odontogenesis and the pathology of oral and dental disorders.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
