Through the use of the novel receptor NER in a screening procedure, TOFA (5-tetradecyloxy)-2-furan-carboxylic acid) has been found to modulate other receptors and to be a potent potentiator of other drugs. TOFA activates the NER receptor. The NER receptor is a novel member of the steroid hormone receptor family and has been prepared by cDNA cloning from a human osteosarcoma SAOS-2/B10 cell library. Also disclosed is the complete sequence of human NER cDNA; a COS stable expression system; the expressed NER protein; and an assay using the COS expression system. In addition, the invention relates to a method for identifying functional ligands of the NER receptor.

Methods of obtaining enriched populations of osteoclast precursor cells which can be released from tissue culture dishes and used for biochemical studies are described. Osteoblastic cells and bone marrow cells are co-cultured. Next a .alpha..sub.v .beta..sub.3 receptor ligand, such as echistatin is used for cell detachment. The result is an 75-95% pure enriched population of tartrate resistant acid phosphatase (TRAP.sup.+) cells, in high yields (2-3.times.10.sup.6 cells per experiment) can be obtained. These cells are mostly mononucleated and based on their characteristics are considered to be pre-fusion osteoclasts (pOC cells). The precursor osteoclasts can be reseeded onto osteoblasts to obtain an enriched population of mature, multinucleated osteoclast cells.

Compounds of structural formula (I) as herein defined are disclosed as useful in a method for modulating the androgen receptor in a tissue selective manner in a patient in need of such modulation, as well as in a method of agonizing the androgen receptor in a patient, and in particular the method wherein the androgen receptor is antagonized in the prostate of a male patient or in the uterus of a female patient and agonized in bone and/or muscle tissue. These compounds are useful in the treatment of conditions caused by androgen deficiency or which can be ameliorated by androgen administration, including: osteoporosis, periodontal disease, bone fracture, bone damage following bone reconstructive surgery, sarcopenia, frailty, aging skin, male hypogonadism, post-menopausal symptoms in women, atherosclerosis, hypercholesterolemia, hyperlipidemia, aplastic anemia and other hematopoietic disorders, pancreatic cancer, renal cancer, arthritis and joint repair, alone or in combination with other active agents. In addition, these compounds are useful as pharmaceutical composition ingredients alone and in combination with other active agents.
摘要:
The present invention relates to methods of identifying compounds useful as modulators of certain stress responsive kinases. More particularly, the compounds so identified are useful for treating or preventing diseases or conditions that are mediated by, for example, abnormal bone resorption or angiogenesis. These compounds are useful for treating or preventing osteoporosis, and inhibiting vascular restenosis, diabetic retinopathy, macular degeneration, angiogenesis, atherosclerosis, inflammation, and tumor growth.
摘要:
The combination of an estrogen receptor modulator and a growth hormone secretagogue is useful in the treatment or prevention of diseases involving bone resorption, especially osteoporosis.
摘要:
A novel member of the Wnt-family of growth factors, termed Wnt-x, has been identified and DNA encoding the growth factor has been isolated, purified, sequenced and expressed in host cells. This DNA encoding the novel Wnt-x protein and host cells expressing the Wnt-x protein are used to identify modulators of the Wnt-x growth factor.
摘要:
Disclosed herein are methods and compositions for identifying morphogen analogs. The preferred methods and compositions relate to the discovery that morphogen upregulation of the mouse type X collagen promoter activity is mediated by a MEF-2 like sequence and requires an adjacent AP-1 sequence. Certain methods rest on the use of test cells comprising DNA defining a morphogen-responsive transcription activating element operatively associated with a reporter gene. Other methods rest on the use of DNAs for measuring morphogen-inducible DNA-binding. In certain preferred embodiments, the methods and DNAs involve an osteogenic protein 1 (OP-1) responsive transcription activating element. Substances that mediate interaction with and/or activate the OP-1 responsive transcription activating element are considered herein likely to be useful for reproducing in vivo effects of morphogens such as OP-1.
摘要:
The NER receptor is a novel member of the steroid hormone receptor superfamily and has been prepared by cDNA cloning from a human osteosarcoma SAOS-2/B10 cell library. The complete sequence of human NER complementary DNA (Seq. ID No. 1), expression systems including a COS stable expression system, the expressed protein (SEQ. ID No. 2) and an assay using the COS expression system are disclosed. The assay may be used to identify agents which activate transcription mediated by the NER receptor, and which are useful for potentiating the activity of a modulator of a G-protein coupled receptor wherein the G-protein coupled receptor is a member of the steroid hormone receptor superfamily.
