项目摘要
Many biological processes are regulated by a cell's ability to sense molecules in its environment and create
an intracellular signal to effect an appropriate biological response. One major signaling pathway involves the
regulation of cAMP levels, which is a function of cAMP synthesis by adenylate cyclases and cAMP
destruction by cAMP phosphodiesterases (PDE). In the fission yeast, Schizosaccharomyces pombe, cAMP
levels are regulated by a glucose signaling pathway that includes a single PDE gene. We have developed
reporter constructs,which confer growth phenotypes that reflect the cell's intracellular cAMP level. We
propose to introduce mammalian PDE genes into our strains, such that the growth behavior will be a function
of PDE activity. We will use such strains to carry out the following two aims. 1) We will conduct high
throughput screening for chemical inhibitors of specific PDEs. Utilizing strains expressing various murine
PDEs (4A, 4B, 8A, 8B), we expect to identify both nonspecific and specific inhibitors. Of note, there are no
known PDE8-specific inhibitors, thus making it difficult to determine the relative role of PDES enzymes in
various biological processes. 2) We will use these strains to screen a cDNA library for biological activatorsof
the target PDE and identify the tissues in which these activatorsare expressed. Strains expressing both the
activator and the target PDE will be subjected to chemical library screens for compounds that inhibit the
activator, rather than the PDE itself. As these activators may be expressed in a subset of tissues in which the
PDE is found, compounds that target the activator may provide a more tissue-specific effect on PDE activity,
and thus provide a therapeutic benefit with less of a side-effect than would be possible for compounds that
target the PDE directly. There is a broad range of diseases that are currently being treated with PDE
inhibitors, or are thought to be amenable to treatment with PDE inhibitors. Therefore, the development of
this in vivo platform to identify chemical and biological regulators of PDEs has the potential of identifying the
next generation of PDE-related Pharmaceuticalsfor the treatment of cardiac, pulmonary, and renal diseases,
as well as certain cancers, cystic fibrosis, multiple sclerosis, rheumatoid arthritis, Huntington's Disease,
allergic rhinitis, psoriasis, schizophrenia, Alzheimer's disease and depression.
许多生物过程受细胞在环境中感知分子的能力并创建的能力来调节
细胞内信号可实现适当的生物学反应。一个主要的信号通路涉及
cAMP水平的调节,这是腺苷酸环化酶和cAMP的cAMP合成的函数
营地磷酸二酯酶(PDE)的破坏。在裂变酵母中,schizosaccharomyces pombe,camp
水平由包括单个PDE基因的葡萄糖信号通路调节。我们已经发展了
记者构造,它赋予反映细胞细胞内营地水平的生长表型。我们
建议将哺乳动物PDE基因引入我们的菌株,以使生长行为将是一种功能
PDE活性。我们将使用此类菌株来执行以下两个目标。 1)我们将高涨
特定PDE的化学抑制剂的吞吐量筛选。利用表达各种鼠的菌株
PDE(4A,4B,8A,8B),我们希望识别非特异性和特定抑制剂。值得注意的是,没有
已知的PDE8特异性抑制剂,因此很难确定PDE酶在
各种生物过程。 2)我们将使用这些菌株筛选cDNA库的生物激活剂
靶PDE并识别这些激活剂表达的组织。表达的菌株
激活剂和靶PDE将受到化学库筛选的抑制化合物
激活器,而不是PDE本身。由于这些激活剂可以在组织的一部分中表达
发现PDE,靶向激活剂的化合物可能会对PDE活性产生更大的特异性影响,
因此,提供的治疗益处的副作用较小,而不是
直接靶向PDE。当前正在用PDE治疗的广泛疾病
抑制剂,或被认为可以接受PDE抑制剂治疗。因此,发展
这个识别PDE的化学和生物调节剂的体内平台具有识别的潜力
下一代与PDE相关的药物治疗心脏,肺部和肾脏疾病,
以及某些癌症,囊性纤维化,多发性硬化症,类风湿关节炎,亨廷顿氏病,
过敏性鼻炎,牛皮癣,精神分裂症,阿尔茨海默氏病和抑郁症。
