摘要:
Aim: To investigate the methylation status of the deleted in azoospermia 1 (DAZ1) gene promoter region in different cell types. Methods: Using CpG island Searcher software, a CpG island was found in the promoter region of the DAZ1 gene. The methylation status of this region was analyzed in sperm and leukocytes by bisulfited sequencing. Results: The methylation status of the CpG island in the DAZ1 gene promoter region differed in leukocytes and sperm: it was methylated in leukocytes, but unmethylated in sperm. Conclusion: A differentially methylated region of the DAZ1 gene exists in spermatic and somatic cells, suggesting that methylation of this region may regulate DAZ1 gene expression in different tissues.
