RAB31 and esophageal squamous cell carcinoma: In this study, the factors mentioned on sixty tumor tissues were compared with the adjacent healthy tissue and it was reported that miR455-5p can be thought as a miR suppressive tumor and plays a significant role in esophageal SCC by typically suppressing the expression of Rab31. It is important to note that soft tissues of the human oral cavity and esophagus are covered everywhere by a stratifying squamous epithelium (Liu et al., 2018).
