  • While studying the activity of BRCA2 gene promoter in breast cancer cells, we discovered that this promoter has bi-directional activity and the product of the reverse activity (a ZAR1-like protein, we named ZAR2) silences the forward promoter at the G0/G1 phase of the cell. (biomedcentral.com)
  • This promoter is 8-20 fold more active in the reverse orientation than in the forward orientation when the cells are in the non-dividing stage (G0/G1). (biomedcentral.com)
  • When the cells are in the dividing state (S/G 2 ), the forward activity of the promoter is 5-8 folds higher than the reverse activity. (biomedcentral.com)
  • We are a global provider of human and animal biospecimens: including frozen & FFPE tissue, DNA, RNA, total proteins, blood products and primary cells. (amsbio.com)
  • Second, OA exposure specifically represses the transcriptional activity of the human HER2 gene promoter in tumor-derived cell lines naturally exhibiting HER2 gene amplification and p185Her-2/neu protein overexpression but not in cancer cells expressing physiological levels of HER2. (eurekaselect.com)
  • Third, OA treatment induces the upregulation of the Ets protein PEA3 (a transcriptional repressor of the HER2 gene promoter) solely in cancer cells naturally displaying HER2 gene amplification. (eurekaselect.com)
  • In the first phase, sender cells grow and accumulate synthase protein. (github.io)
  • This propagation ends at the third phase, when cell growth and protein production slow down such that the amplifier cells cannot produce enough synthase protein to sustain signal transmission. (github.io)
  • Protein quantity is also diminished through dilution as cells grow and divide. (github.io)
  • The KRAB domain is a protein-protein interaction module which represses transcription through recruiting corepressors. (embl.de)
  • The key co-repressor complex components HDAC-2, Mi-2α/β and mSin3a are all critical to the regulation of gene transcription. (biomedcentral.com)
  • Furthermore, Akirin2 and IκB-ζ recruitment to the Il6 promoter depend upon the presence of IκB-ζ and Akirin2, respectively, for regulation of chromatin remodeling. (cnrs.fr)
  • This study characterized high-quality whole-genome sequences of a sentinel, surveillance-based collection of 1710 Neisseria gonorrhoeae (GC) isolates from 2019 collected in the USA as part of the Gonococcal Isolate Surveillance Project (GISP). (cdc.gov)
  • The 1710 isolates represented 164 multilocus sequence types and 21 predominant phylogenetic clades. (cdc.gov)
  • While the gene circuit parameters inferred from liquid-culture experiments are maintained, microscope data are used to determine parameters governing nutrient-dependent growth and protein production. (github.io)
  • The times below were that site-specific selection of self-esteemproblems has on the survival of the & of splines so that higher gene strains and larger promoter saponins show more adjacent biomarkers. (scoutconnection.com)
  • Temperature has a direct effect on fundamental biological systems, including enzyme activity and correct folding of proteins. (springer.com)
