RNA-sequencing reveals signaling pathway associated with cell adhesion in Fam83h-mutated cells

Truncation mutations in family with sequence similarity, member H (FAM83H) gene cause autosomal dominant hypocalcified amelogenesis imperfecta (ADHCAI). The aim of this study was to explore the effects of truncated FAM83H on enamel development. High throughput RNA-sequencing was used to detect the dysregulated signaling pathways in Fam83h-mutated LS8 cells. According to mRNA-sequencing, pathway related to cell adhesion was the most notably clustered in Fam83h-mutated cells. Immunofluorescence analysis further revealed decreased protein expression of desmoglein 3, a component of desmosomes, in Fam83h-mutated cells. RNA-seq in the LS8 cell line before and after mutation of Fam83h (c.1186C > T, p.Q396*)
