1、Cellular chemical staining and transmission electron microscope results also show that ATRA could induce HL60 cells to granulocyte cells.───细胞化学染色和透射电镜结果亦表明诱导后的HL60细胞向粒系分化。
2、Thus, we studied whether maintenance therapy in ALL, like ATRA in APL , may be inducing terminal differentiation of ALL progenitors.───像在APL上使用ATRA一样，我们研究的所有维持疗法都可以诱导原生组织分化。
3、ATRA could inhibit HL60 cell proliferation, and with the increase in drug concentration, the effect of inhibiting the more significant.───ATRA明显抑制HL60细胞增殖，并随药物浓度的增加，抑制效果也越显著；
4、Objective to study the mechanism of drug resistance of APL to ATRA and the methods of reversion.───目的揭示急性早幼粒细胞白血病产生维甲酸耐药的机制，探讨耐药性逆转的方法。
5、Trypan blue exclusion was used to detect the antiproliferative effect of ATRA on SY5Y cells.───盼蓝拒染法检测ATRA对SY5Y细胞的体外抗增殖作用；
6、METHODS CTX-dwas fractionated and purified from Naja naja atra venom by column chromatography and RP-HPLC.───方法应用柱层析及RP- HPLC，从眼镜蛇毒粗毒中分离纯化细胞素素 (C T X)。
7、Results There were obvious differences in gene expression between human lung cancer cells before and after ATRA treatment.───结果在全反式维甲酸诱导前后的细胞之间存在明显的基因表达差异。
8、Recently, all-trans retinoic acid (ATRA) has been used as an antifibrosis drug in many experimental models.───近来较多的研究表明全反式维甲酸 (A T R A)具有抗纤维化作用。
1、Curcumin , a JNK blocker , blocked ATRA inhibition of cell growth.
2、Lisinopril, prednisone and all-trans retinoic acid (ATRA) were administered once a day to the adriamycin-induced nephrotic rats at the first day after adriamycin injection respectively.
3、The TM transcription and expression upregulated by ATRA may alleviate dysfunction of coagulation in APL.
4、ALL maintenance therapy utilizes low-dose 6- mercaptopurine (6MP) and methotrexate (MTX), while maintenance in APL primarily consists of all-trans-retinoic acid (ATRA).
5、OBJECTIVE To purify cytotoxin(CTX) from Naja naja atra venom, and to study its antitumor activity.
6、Aim To elucidate the molecular mechanism of granulocytic differentiation of human promyelocytic leukemia HL 60 cells induced by all trans retinoic acid (ATRA).
7、Conclusion The combination of ATRA with bufalin can significantly enhance the differentiation of NB4 cells in vitro culture by ATRA.
8、But Atra declined to provide an independent auditor.
9、The results show that Naja naja atra cobra venom injection is safe for therapeutic use.
