    • In accordance with the present invention, it has been discovered that histone deacetylase associates with hormone receptor complexes and contributes to the repression thereof. It has further been discovered that exposure of a repressed system to histone deacetylase inhibitors relieves this repression, and that in combination with a ligand for a member the steroid/thyroid superfamily of receptors, the differentiation effects of retinoids are enhanced. Thus, histone deacetylase inhibitors have been found to be useful for the activation of genes responsive to hormone receptors and to conteract the oncogenic functions of oncogenic proteins. In accordance with another aspect of the invention, formulations useful for modulation of hormone-mediated processes have been developed. In addition, assays have been developed for the identification of compounds useful to modulate the above-described processes as well as methods of employing such compounds for the treatment of neoplastic diseases.

    • The present invention relates to the identification, isolation, sequencing and characterization of a new member of the histone deacetylase family, as well as its transcripts, gene products, associated sequence information, and related genes. The present invention also relates to methods for detecting and diagnosing carriers of normal and mutant alleles of these genes, methods for detecting and diagnosing diseases, methods of identifying genes and proteins related to or interacting with such genes and proteins, methods of screening for potential therapeutics for diseases, methods of treatment for diseases, and to cell lines and animal models useful in screening for and evaluating potentially useful therapies for diseases. In a particular aspect of the present invention, a novel family member, HDAC7, is described and its interaction with SMRT/N-CoR and mSin3A, its biochemical properties and subcellular localization are characterized. In addition, evidence is provided that the HDAC4, 5, and 7 deacetylases may mediate nuclear receptor repression. The findings described here indicate that two or more classes of histone deacetylases can collectively contribute to SMRT/N-CoR action and that at least some deacetylases may directly associate with SMRT/N-CoR in a mSin3A independent fashion.

    • In accordance with the present invention, there are provided targeted loss of function mutant mice which express less than endogenous levels of at least one member of the steroid/thyroid superfamily of receptors in at least one specific tissue type. For example, mutations in the RXR&agr; gene in mouse germlines are lethal in the embryonic stage between E13.5 and E16.5 when bred to homozygosity. The major defect responsible for this lethal effect is hypoplastic development of the ventricular chambers of the heart, which is manifest as a grossly thinned ventricular wall with concurrent defects in ventricular septation. This phenotype is identical to a subset of the effects of embryonic vitamin A deficiency, and therefore establishes RXR&agr; as a genetic component of the vitamin A signaling pathway in cardiac morphogenesis. The cardiac outflow tracts and associated vessels, which are populated by derivatives of the neural crest and which are also sensitive to vitamin A deficiency, are normal in homozygous embryos, indicating the genetic independence of ventricular chamber development. Hepatic differentiation was dramatically but transiently retarded, yet is histologically and morphologically normal. These results ascribe an essential function for the RXR&agr; gene in embryonic development, and provide the first evidence of a requirement for RXR in one of its predicted hormone response pathways.
    • 根据本发明,提供了在至少一种特定组织类型中表达低于受体的类固醇/甲状腺超家族的至少一种成员的内源水平的功能突变小鼠的靶向丧失。 例如,当培育成纯合子时,E13.5和E16.5之间的胚胎阶段,小鼠种系中RXRalpha基因的突变是致命的。 负责这种致死作用的主要缺陷是心脏心室的发育不良,这表现为心室隔膜同时缺陷的严重变薄的心室壁。 这种表型与胚胎维生素A缺乏症的一个亚组相同,因此在心脏形态发生中建立了RXRalpha作为维生素A信号通路的遗传成分。 由神经嵴的衍生物填充并且对维生素A缺乏敏感的心脏流出道和相关血管在纯合胚中是正常的,表明心室发育的遗传独立性。 肝分化显着但短暂延迟,但组织学和形态学正常。 这些结果归因于胚胎发育中RXRalpha基因的基本功能,并提供了其预测的激素反应途径之一的RXR要求的第一个证据。
