摘要
配对盒基因2(paired box2,PAX2)是一种核转录因子,表达在发育期肾脏。研究表明PAX2通过与PTIP的相互作用使染色质处于可转录状态,与Grg4的相互作用削弱了其与PTIP结合而抑制转录。 PAX2在急性肾损伤时再表达,参与促进细胞增殖修复。先天PAX2基因突变与先天性肾脏输尿管异常密切相关。在慢性肾脏疾病,PAX2起到促进增殖及囊肿形成的作用。该文就PAX2的功能及其在急性肾损伤和慢性肾脏疾病中作用的相关研究进行综述。
Paired box2 ( PAX2 ) is a transciption factor which mainly expressed in the developing kid-ney. Researches indicate that PAX2 promote the transcription through interactions with the adaptor PAX transac-tivation domain interacting protein(PTIP). Otherwise,PAX2 protein can lead to chromatin compaction and gene silencing through interactions with Grg4. PAX2 reexpressed in acute kidney injury and involved in promoting cell proliferation. Congenital PAX2 gene mutation is closely related to congenital abnormalies of the kidney and uri-nary tract. In chronic kidney disease,PAX2 promote proliferation and cyst formation. Here,the recent researches on the function of PAX2 and its role in acute kidney injury and chronic kidney disease are reviewed.
