[[http://www.uniprot.org/uniprot/NCOA1_HUMAN NCOA1_HUMAN]] Note=A chromosomal aberration involving NCOA1 is a cause of rhabdomyosarcoma. Translocation t(2;2)(q35;p23) with PAX3 generates the NCOA1-PAX3 oncogene consisting of the N-terminus part of PAX3 and the C-terminus part of NCOA1. The fusion protein acts as a transcriptional activator. Rhabdomyosarcoma is the most common soft tissue carcinoma in childhood, representing 5-8% of all malignancies in children. | |||

[[http://www.uniprot.org/uniprot/VDRA_DANRE VDRA_DANRE]] Nuclear hormone receptor. Transcription factor that mediates the action of vitamin D3 by controlling the expression of hormone sensitive genes. Regulates transcription of hormone sensitive genes via its association with the WINAC complex, a chromatin-remodeling complex. Plays a central role in calcium homeostasis.<ref>PMID:17218092</ref> [[http://www.uniprot.org/uniprot/NCOA1_HUMAN NCOA1_HUMAN]] Nuclear receptor coactivator that directly binds nuclear receptors and stimulates the transcriptional activities in a hormone-dependent fashion. Involved in the coactivation of different nuclear receptors, such as for steroids (PGR, GR and ER), retinoids (RXRs), thyroid hormone (TRs) and prostanoids (PPARs). Also involved in coactivation mediated by STAT3, STAT5A, STAT5B and STAT6 transcription factors. Displays histone acetyltransferase activity toward H3 and H4; the relevance of such activity remains however unclear. Plays a central role in creating multisubunit coactivator complexes that act via remodeling of chromatin, and possibly acts by participating in both chromatin remodeling and recruitment of general transcription factors. Required with NCOA2 to control energy balance between white and brown adipose tissues. Required for mediating steroid hormone response. Isoform 2 has a higher thyroid hormone-dependent transactivation activity than isoform 1 and isoform 3.<ref>PMID:9427757</ref> <ref>PMID:7481822</ref> <ref>PMID:9223431</ref> <ref>PMID:9296499</ref> <ref>PMID:9223281</ref> <ref>PMID:10449719</ref> <ref>PMID:12954634</ref> | |||

== Publication Abstract from PubMed == | |||
1We report the design, synthesis, biological evaluation and structural analysis of a new class of vitamin D analogs that possess an aromatic m-phenylene D-ring and an alkyl chain replacing the C-ring. A key feature of the synthetic strategy is a stereoselective Pd-catalyzed construction of the triene system in aqueous medium that allows the rapid preparation of small amounts of VDR ligands for biological screening. Analogs with the shorter (2a) and longer (2d, 2e) side chains attached to the triene system have no calcemic activity. Compound 2a binds to VDR with the same order of magnitude than calcipotriol and oxacalcitriol. It also reduces proliferation in normal and tumor cells similarly to the natural hormone 1a,25-dihydroxyvitamin D3, calcipotriol and oxacalcitriol, suggesting preclinical studies related to hyperproliferative disorders such as psoriasis and cancer. | |||
