五子衍宗丸对ATRA诱导的神经管畸形防治作用初探

目的初步研究五子衍宗丸对全反式维甲酸(all-trans-retinoic acid,ATRA)诱导的神经管畸形(neural tube defects,NTDs)的防治作用,并筛选出五子衍宗丸防治NTDs的最佳给药方式。方法 BALB/c雄鼠和雌鼠以1∶2比例合笼,有阴栓者为孕鼠。将110只孕鼠随机分为正常组、模型组、五子衍宗丸先给组、五子衍宗丸和ATRA同时干预组、五子衍宗丸后给组,后3组又各分为五子衍宗丸高(4.20 g/kg...  (本文共3页) 阅读全文>>

Down-Regulation of CD44 Contributes to the Differentiation of HL-60 Cells Induced by ATRA or HMBA

CD44 is highly expressed in human acute myeloid leukemia (AML) cells. Some experiments had shown that it was possible to reverse differentiation blockage in AML cells by CD44 ligation with specific antibodies, indicating that CD44 was closely related to the differentiation of leukemia cells. The differentiation of acute promyelocytic leukemia cell line HL-60 cells could be induced by all trans-retinoic acid (ATRA) an...  (本文共5页) 阅读全文>>

Effects of varied interferons in combination with all-trans retinoic acid ( ATRA ) on proliferation and differentiation of ATRA-resistent APL cell

Objective: To investigate the effects and mechanisms of interferon in combination with all-trans retinoic acid (ATRA) on proliferation and differentiation of ATRA-resistent APL cell. Methods:After MR2 cells (ATRA-resistance cell line) were treated with IFN-α, IFN-γand ATRA alone or IFN-αand IFN-γin combination with ATRA respectively. The cell proliferation was tested by MTT test and the cell differentiation was teste...  (本文共6页) 阅读全文>>

The Effect of Sodium Butyrate in Combination with ATRA on the Proliferation/Differentiation of SKM-1

To explore the molecular mechanisms of sodium butyrate working on SKM-1 cell proliferation/differentiation and to study its synergistic effect with all-trans retinoic acid (ATRA), SKM-1 cells were grown in the absence or presence of sodium butyrate and/or ATRA. The percentage of viable cells was determined by trypan blue exclusion. Differentiation was determined by nitroblue tetrazolium (NBT) reduction and cell surfa...  (本文共4页) 阅读全文>>
