  • ARID1A, encoding a subunit of the SWI/SNF complex, is the most frequently mutated epigenetic regulator in human cancers and is mutated in more than 50% of ovarian clear cell carcinomas (OCCC), a disease that currently has no effective therapy. (aacrjournals.org)
  • 1, 2, 3] Approximately 20% of the genes expressed in human leukocytes are regulated positively or negatively by glucocorticoids. (medscape.com)
  • In the past biennium, working groups have concluded that there is sufficient evidence to classify infection with human immunodeficiency virus (HIV-1), human T-cell lymphotropic virus (HTLV-1), Epstein-Barr virus (EBV) and the Kaposi sarcoma-associated herpesvirus 8 as carcinogenic to humans (IARC 0RQRJUDSKV, Vol. 67 and 70).

  • Use a multiplex assay that targets multiple viral genes, or an assay that targets an essential viral gene which is unlikely to mutate, or an assay that detects non-variola Orthopoxvirus . (cdc.gov)
  • The human GR is a modular protein composed of distinct regions illustrated in panel B in the image below, as follows: (1) The amino-terminal A/B region, also called immunogenic or N-terminal domain (NTD) and (2) the C, D, and E regions, which correspond to the DNA-binding domain, the hinge region, and the ligand-binding domain, respectively.

  • The demonstration of what could happen was great, and they used mice because it's a more tractable system, but what we cared about were humans. (medscape.com)
  • C) Move terms significantly from the upregulated genes in organoids ectopically expressing organoids at chosen timepoints. (exposed-skin-care.net)
  • We have also examined the role of the DCC tumour-suppressor gene in the development of human soft-tissue tumours in a variety of histological types. (nih.gov)
  • For example, Zhang and Li found that housekeeping genes evolved more slowly than tissue-specific genes [ 10 ]. (biomedcentral.com)
