Embodiment 1
[0063] Example 1 Cloning and identification of methylated ELF gene promoter regulatory region
[0064] The tumor suppressor gene ELF is expressed in normal liver tissue, while its expression is down-regulated in liver cancer stem cells and liver cancer tissues, and knocking out the ELF gene in mice leads to spontaneous liver cancer, indicating that ELF plays an important role in the early stage of liver cancer. The regulatory mechanism of ELF gene silencing under natural conditions is still unclear. The present invention explores the relationship between the methylation state of the CpG island in the promoter region of the ELF gene promoter region and HCC from the perspective of DNA methylation, and lays an experimental foundation for further analysis of the methylation state of the ELF gene promoter region in tumor tissues and body fluid samples .
[0065] In this example, the regulatory sequence of the ELF gene promoter region (ELFpro, 435 bp) was amplified by PCR method, a...
Embodiment 2
[0089] Example 2 Study on the relationship between the methylation status of the CpG island in the promoter region of the ELF gene and liver cancer
[0090] 1 Materials and methods
[0091] 11 cell lines
[0092] What used in this experiment is all conventional cell lines that have been reported in the art. The purpose of using these cell lines in this experiment is to serve as positive control cell lines for CpG island methylation, to illustrate the present invention, and to implement the technical solution of the present invention. independent of these cell lines. Instead of using these cell lines, other cell lines that have been reported that the CpG island of the corresponding gene has been methylated can also serve the above role, and even the sequence of the CpG island of the corresponding gene that has been reported can be used. Refer to the method in Example 1 , to prepare a positive template for the complete methylation of the gene promoter region, or to prepare a p...
