  • ERBB is abbreviated from erythroblastic oncogene B, a gene isolated from avian genome. (iiab.me)
  • Expression of each cluster's gene signatures was validated using multiplex fluorescence in situ hybridization (FISH) co-stained with piwi-1 and largely confirmed the cell clusters revealed by scRNA-seq. (stowers.org)
  • Cluster identity was assigned based on the top 10 marker genes of each cluster ( Table S2 ), followed by inspection of RNA in situ hybridization patterns. (stowers.org)
  • The HER-2/neu gene was localized using the Oncor (Gaithersburg, MD) digoxigenin-labeled unique sequence probe. (nih.gov)
  • Sequence analysis of this genomic DNA fragment revealed that the 2.6-kb c-erbB transcript is produced by alternative processing. (elsevierpure.com)
  • Furthermore, we detected an association (P=0.04) between the expression of AP-2γ and the presence of an additional signal transduction molecule implicated in breast cancer, the insulin-like growth factor I receptor. (johnshopkins.edu)
  • Analysis of the proximal promoter of the insulin-like growth factor I receptor revealed a novel AP-2-binding site. (johnshopkins.edu)
  • Neuregulin 2 (NRG2) is a novel member of the neuregulin family of growth and differentiation factors. (wikipedia.org)
  • Taken together, these data strongly support a role for the AP-2 gene family in the control of cell growth and differentiation in breast cancer. (johnshopkins.edu)
