摘要: 摘要:USP22是一种泛素特异肽酶,属于DUBs家族,是hSAGA复合物的一个亚单位,参与组蛋白去泛素化、乙酰化进而参与hSAGA复合物所调节的基因转录与表达等。目前认为USP22是癌死亡标签之一,并且它与癌的增殖、侵袭转移和治疗预后相关。USP22与肿瘤发生发展的机制主要与Polycomb家族成员之一BMI-1和Myc、FBP1、TRF1等多种因子有关,这一特点使其可能成为肿瘤干细胞标志物之一。

Abstract: Abstract: USP22 is the ubiquitin-specific peptidase and a subunit of hSAGA complex subunit, belonging to the DUBs. Within hSAGA, USP22 deubiquitylates histone H2A and H2B and acetyltransfers H4 to regulate the transcription and expression of the related genes.Now that it is believed that USP22 is one of the death-from-cancer signature and associated with proliferation,invasion,metastasis and poor prognosis. It promotes the occurrence and development of tumor corresponding with the BMI-1,which is one of the Polycomb group, and Myc,FBP1 ,TRF1 .That makes it possible to become one of the tumor stem cell markers.

Key words: Keywords: USP22, death-from-cancer signature, tumor stem cell marker
