LincRNA-ASAO promotes dental pulp repair through interacting with PTBP1 to increase ALPL alternative splicing.

ABSTRACT:

Background

Alternative splicing not only expands the genetic encoding of genes but also determines cellular activities. This study aimed to elucidate the regulation mechanism and biological functions of lincRNA-ASAO in the process of odontogenesis-related genes alternative splicing mediated odontogenic differentiation of hDPSCs.

Methods

RACE, RNA-seq, FISH and bioinformatics techniques were used to identify novel lincRNA-ASAO. ALP staining, alizarin red staining, qRT-PCR and western blot were used to identify the role of lincRNA-ASAO in regulating the odontoblast differentiation of hDPSCs. The binding protein PTBP1 of lincRNA-ASAO was screened by RNA-Pulldown, protein profiling and bioinformatics. The target gene ALPL of lincRNA-ASAO/PTBP1 was identified by RNA-seq, bioinfor
