The expression of NOTUM in replantation of severed fingers may be an important treatment factor.
Annals of Human Genetics 2022 December 6
INTRODUCTION: After years of development, digital replantation has become a mature treatment.
METHODS: Although the NOTUM gene has been shown to be involved in the formation of vertebrate nerves, whether it contributes to the osteogenic mechanism of severed finger replantation remains unknown. In response to this, this study investigates the specific details of NOTUM involvement in replantation of severed fingers.
RESULTS: The experimental subjects are patients with replantation of severed fingers from Shulan International Medical College of Shulan (Hangzhou) Hospital affiliated to Zhejiang Shuren University. In addition to using bone marrow mesenchymal stem cells (BMSCs) as an in vitro system, this experiment also involves quantitative PCR, microarray analysis, cell counting Kit-8, EDU staining and Western blot analysis. The expression level of NOTUM in the severed finger replantation group is lower than that in the normal group. NOTUM inhibits cell growth and cell transfer, osteogenic differentiation and β-catenin gene expression in BMSCs. Luciferase reporter assay illustrated that β-catenin wild type closely correlated with NOTUM. The inhibition of β-catenin increases the effects of NOTUM on cell growth, cell transfer and osteogenic differentiation of BMSCs.
CONCLUSION: Considering that NOTUM can inhibit cell growth, cell transfer, osteogenic differentiation of BMSCs, as well as the gene expression of β-catenin, it may be a biomarker of osteogenic differentiation and a potential therapeutic target for replantation of severed fingers.
