  • The SWI5 gene product was overproduced in yeast from the GAL1-10 promoter, since the SWI5 protein is made at very low levels in wild-type strains, and protein extracts were used to demonstrate that the SWI5 protein binds in vitro to a segment of the HO promoter required for transcriptional activation in vivo.

  • Metallothioenein-1 and Metallothioenein-2 genes, which protect cells against cytotoxicity induced by toxic metals, are also direct targets of Nfe2l1. (wikipedia.org)
  • Re-establishment of Nfe2l1 function in Nfe2l1 null cells rescued proteasome expression and function, indicating Nfe2l1 was necessary for induction of proteasome genes (bounce-back response) in response to proteasome inhibition. (wikipedia.org)
  • Genetic regulatory networks programming hematopoietic stem cells and erythroid lineage specification. (ox.ac.uk)
  • Combinations of MIMs, exemplified by the SCL/LMO2 complexes, which have variable content and binding sites, explain how individual regulators can have different targets in HSCs and erythroid cells and possibly also how HSCs maintain stem cell functions while expressing lineage-affiliated genes at low level, so-called multi-lineage priming. (ox.ac.uk)
  • Expression of this gene isinsulin-responsive, and studies in rat suggest that it is involved in the increased rate of glycolysisseen in rapidly growing cancer cells. (biomasswars.com)
  • E2F6 cooperates with MGA to silence a subgroup of germline genes in mouse embryonic stem cells and in embryos, a function that critically depends on the E2F6 marked box domain. (cnrs.fr)
  • 2008). Historically, this concept is highlighted by the experi- factors are key intrinsic regulators of these fate decisions and mental phenomenon of lineage reprogramming, for example, that fate choice involves modulating networks of transcription by the conversion of fibroblasts to muscles cells following trans- factors. (lu.se)
  • Similarly, GATA-1 has been shown to induce lineage switching expression values even if, for simplicity, we assume only ``on'' of committed cells in hematopoiesis, first in cell lines (Kulessa and ``off'' states for each gene. (lu.se)
  • In reality, gene somatic cells to a pluripotent cell state by a handful of transcrip- expression is graded, making the potential gene expression tion factors (Takahashi and Yamanaka, 2006). (lu.se)
  • In most metazoans, GCN2 is one of the four known kinases that phosphorylate eukaryotic initiation factor 2, α subunit (eIF2α) to inhibit translation initiation [ 19 ]. (biomedcentral.com)
  • GBS production of β-h/c is encoded by the genes of the cyl operon ( 5 , 6 ) and is associated with direct lysis of a variety of eukaryotic cell types ( 7 - 9 ), inflammatory activation ( 10 - 12 ), and virulence in animal models ( 10 , 13 , 14 ). (cdc.gov)
  • Finally, we established that the LIP1 and IPS1 elements were differentially bound by HD-ZIP and MYB-CC family members in agreement with their genetic redundancy in planta. (upm.es)
  • Regulatory network motifs identified in E. coli and yeast GRNs are found in combination in these GRNs. (ox.ac.uk)
  • Saccharomycopsis fibuligera (synonymous with Endomyces fibuligera ), a member of the subphylum Saccharomycotina of the phylum Ascomycota of the Fungi kingdom, is found worldwide as the major amylolytic yeast utilized in indigenous food fermentation using rice and cassava. (biomedcentral.com)
  • Surprisingly, we have found that all tested target genes can be activated by lower concentrations than those present in the wild type gradient where boundaries for those genes are formed. (nyu.edu)
  • The EIF2AK4 gene is found on chromosome 15 . (medlineplus.gov)
  • Drosophila immune deficiency (IMD) pathway is similar to the human tumor necrosis factor receptor (TNFR) signaling pathway and is preferentially activated by Gram-negative bacterial infection. (cnrs.fr)
  • METHODS: Mice with K/BxN serum-induced arthritis, collagen-induced arthritis, and human tumor necrosis factor transgene insertion were studied. (cnrs.fr)
