  • Publication number: 20200140856
    Abstract: A cell model for in vitro evaluation of compound-induced skin sensitization and a constructing method therefor. The method for constructing the cell model comprises the steps of: designing and constructing an sgRNA expression vector based on CRISPR/Cas9 vector system; designing and constructing a homologous recombinant vector capable of knocking a reporter gene linked to a self-cleaving peptide sequence into a specific site of the expression frame of the HMOX1 gene; co-transfecting the homologous recombinant vector, an hCas9 plasmid and the sgRNA expression vector into a cell, and carrying out monoclonal expansion to obtain the cell model. The present invention obtains a HaCaT cell model in which a luciferase gene is knocked in before the stop codon of the HMOX1 gene by combination of CRISPR/CAS9 and a monoclonal cell technique. The cell model realizes synchronous expression of the luciferase gene and the HMOX1 gene, thereby effectively distinguishing sensitizing compounds from non-sensitizing compounds.
