PU.1是ETS转录因子家族(E26 transformation-specific family)的成员,在机体多种组织发育中发挥重要作用。近年来的研究发现,PU.1不仅在造血谱系的确定和分化中起作用,而且还在机体免疫、脂肪形成、组织纤维化、神经发育中发挥功能。在造血及免疫等系统中,PU.1与多个靶基因形成复杂的调节网络,并且PU.1受组蛋白修饰和非编码RNA等表观遗传的调控,参与细胞增殖、分化等多个过程,对维持细胞稳态具有一定意义。PU.1与红细胞白血病、前B细胞急性淋巴细胞白血病、急性髓细胞白血病、过敏性疾病、类风湿性关节炎、肥胖相关疾病、骨硬病、神经胶质瘤等疾病的发生相关。该文从功能方面阐述PU.1的最新研究进展,为该基因和ETS家族的后续研究提供新思路。 相似文献

The lipoxygenase (LOX) pathway was proposed to compete with hydrolysis and be partly responsible for the metabolism of polyunsaturated N-acylethanolamines (PU-NAEs). Treatment of Arabidopsis seedlings with lauroylethanolamide (NAE 12:0) resulted in elevated levels of PU-NAE species, and this was most pronounced in plants with reduced NAE hydrolase activity. Enzyme activity assays revealed that NAE 12:0 inhibited LOX-mediated oxidation of PU lipid substrates in a dose-dependent and competitive manner. NAE 12:0 was 10-20 times more potent an inhibitor of LOX activities than lauric acid (FFA 12:0). Furthermore, treatment of intact Arabidopsis seedlings with NAE 12:0 (but not FFA 12:0) substantially blocked the wound-induced formation of jasmonic acid (JA), suggesting that NAE 12:0 may be used in planta to manipulate oxylipin metabolism. 相似文献
