Abstract: The present invention discloses a method for establishing a colorectal cancer p73 reporter gene cell line, specifically including: first designing a site-specific sgRNA sequence of a p73 gene and cloning same into a plasmid PX459; integrating a homologous recombination sequence of the p73 gene and a green fluorescent protein DNA fragment (EGFP), and transforming the plasmid and the integrated fragment together into a colorectal cancer cell line HCT116 by electroporation; performing signal cell screening through a flow cytometer to obtain EGFP-expressing cells, and amplifying a monoclonal cell line; and identifying a positive p73 reporter gene cell line through PCR identification and Western blot, among screened EGFP-expressing cell lines. The colorectal cancer cell line p73 gene and the EGFP are co-expressed, and the expression level of the EGFP is highly consistent with that of the p73 gene.

Abstract: The present invention discloses a method for establishing a colorectal cancer HK2 reporter gene cell line, specifically including: firstly, designing a site-specific sgRNA sequence of an HK2 gene, and cloning same into a PX459 plasmid; integrating a homologous recombination sequence of an HK2 gene and a green fluorescent protein DNA fragment (EGFP), and transforming the plasmid and the integrated fragment together into a colorectal cancer cell line HCT116 by electroporation; and performing signal cell screening through a flow cytometer to obtain EGFP-expressing cells, and amplifying a monoclonal cell line; and identifying a positive HK2 reporter gene cell line through PCR identification and Western blot, among screened EGFP-expressing cell lines. The colorectal cancer cell line HK2 gene and EGFP are co-expressed, and the expression level of the EGFP is highly consistent with that of the HK2 gene.
