ATF3 (Activating Transcription Factor 3) is a 181-amino-acid stress-inducible bZIP transcription factor that binds DNA as homo- or heterodimer, recognized by the consensus TGACGTCA, and acts as a dual-function transcriptional regulator—repressing or activating target genes involved in apoptosis, inflammation, cell-cycle checkpoints, metabolic reprogramming and oncogenesis—rapidily up-regulated in response to hypoxia, DNA damage, cytokines, ER stress or mechanical strain, frequently overexpressed in cancers where it promotes survival, metastasis and chemoresistance yet can also function as a tumor suppressor depending on cellular context, and is subject to tight control via MAPK, NF-κB, p53 and multiple feedback loops, making it a critical node in integrating stress signals and determining cell fate.

免疫组化
IHC shows positive staining in paraffin-embedded human placenta. Anti-ATF3 antibody was used at 1/500 dilution, followed by a HRP Polymer for Mouse & Rabbit IgG (ready to use). Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with IHC staining protocol.

ICC analysis of THP-1 cells treated with Phorbol-myristate-acetate(80nM,16h), then LPS(1ug/ml,8h) (top panel) and untreated THP-1 cells (below panel). Anti- ATF3 antibody was used at 1/500 dilution (Green) and incubated overnight at 4°C. Goat polyclonal Antibody to Rabbit IgG - H&L (Alexa Fluor® 488) was used as secondary antibody at 1/1000 dilution. The cells were fixed with 4% PFA and permeabilized with 0.1% PBS-Triton X-100. Nuclei were counterstained with DAPI (Blue). Counterstain with tubulin (Red).
