Background

8-Bromo-cAMP is a cAMP-analogues. [1]

cAMP can have an effect on the proliferative response of a cell. Either the effect is a positive or a negative regulator depending on the cell types. There is also variable effect of cAMP in hematopoietic cell lines. CAMP-analogues can significantly inhibit the erythropoietin-stimulated proliferation.[1]

8-Bromo-cAMP increased the cellular content of mRNA encoding the hCG a- and β-subunits and prevented the increase in fibronectin mRNA. This is determined by blot hybridization analysis using specific cDNA probes. 8-Bromo-cAMP also induced phosphorylation of Erk1,2 in AML193 cells. 8-Bromo-cAMP is an agent in AML193 cells and activates Erk1,2 , this condition happens does not accompanied by the involvement of Shc phosphorylation.[1,2]

8-bromo-cAMP increases catecholamine biosynthesis and produces an increase both in the activity and phosphorylation of tyrosine hydroxylase. 8-bromo-cAMP also promotes alterations in the synthesis and secretion of specific proteins, including fibronectin and the subunits of hCG by regulating mRNA expression.[2,3]

一般建议为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同厂家不同批次产品溶解度各有差异,仅做参考。若实验所需浓度过大至产品溶解极限,请添加助溶剂助溶或自行调整浓度。

试验操作

细胞实验 [1]:

细胞系

生长停滞的AML193细胞

制备方法

在灭菌水中的溶解度为100 mM。若配制更高浓度的溶液,一般步骤如下:请将试管置于37 °C加热10分钟和/或将其置于超声波浴中震荡一段时间。原液于-20 °C可放置数月。

反应条件

0 ~ 15 μM

实验结果

在生长停滞的AML193细胞中,8-Bromo-cAMP显著增加DNA合成,其ED50值约为10 μM。当剂量高于2.5 μM时,8-Bromo-cAMP显示毒性作用。加入1 μM 8-Bromo-cAMP可以增强IL-3诱导的促有丝分裂反应。此外,8-Bromo-cAMP在1μM的剂量下使Erk磷酸化程度达到最高。然而,8-Bromo-cAMP对Erk磷酸化的作用短暂,其最强作用于1 ~ 5分钟内显示。
