染色體易位的分子機(jī)制
[Abstract]:Chromosome translocation is a serious genomic defect, the main cause of which is the wrong repair of double strand breaks of DNA. Chromosome translocation plays a key role in the carcinogenesis and development of tumors. Although studies on this field have been reported in the last 40 years, the intrinsic mechanism of chromosome translocation in cells needs to be further studied and discussed. In recent years, studies have elucidated the steps of chromosome translocation formation, and found that in the process of translocation, various factors include DNA double strand break repair system, chromosome structure and spatial location. Histone modification plays an important role in the process of increasing the frequency of chromosome translocation and the pairing of broken ends. This study summarized the molecular mechanism of chromosome translocation in recent years, and discussed the causes, processes and effects of each part on the formation of chromosome translocation in recent years, and discussed the reasons for the formation of chromosome translocation, the process and the effects of each part on the formation of chromosome translocation.
