  • URB is expressed in human dermal papilla cells (PMID:15998583)
  • In conclusion, the expression pattern of URB suggests its role in obesity and the results suggest that URB is secreted, at least in part, from adipocytes. (PMID:18178152)
  • The CCDC80 protein has three P-DUDES structural domains. These domains have significant albeit remote sequence similarity to thioredoxin-like domains and are predicted to have an oxidoreductase function. (PMID:209648)
  • Results reveal DRO1 as an AIB1-targeted tumor suppressor, providing a novel mechanism for AIB1-dependent inhibition of apoptosis. (PMID:21871888)
  • Data suggest that CCDC80 expression is down-regulated in many thyroid carcinomas; loss of heterozygosity partially accounts for CCDC80 down-regulation in thyroid carcinoma; CCDC80 expression positively regulates expression of E-cadherin. (PMID:23666966)

  • Ccdc80 is a novel betacat-regulated gene in adrenocortical cells (PMID:25029241)
  • Our finding of upregulated CCDC80 expression in the visceral adipose tissue of obese patients indicates that it may be a component of the obesity-altered secretome in this depot. Furthermore, the presence of CCDC80 protein in human serum and its association with systemic metabolic dysfunction suggests that it may be linked to metabolic changes in other organs. (PMID:28850155)
