Immunocytochemistry/ Immunofluorescence - Anti-CHOP antibody [9C8] (AB11419)
ab11419 staining DDIT3 in HeLa (Human epithelial cell line from cervix adenocarcinoma) cells +/- Tunicamycin 1.5μM, 6 hours (ab120296).
The cells were fixed with 4% PFA (10 min), permeabilized with 0.1% Triton-X for 5 mins and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1%PBS-Tween for 1h. The cells were then incubated overnight at +4°C with ab11419 at 5μg/ml and ab6046, Rabbit polyclonal to beta Tubulin - Loading Control, at 1/1000 dilution. Cells were then incubated with ab150117, Goat Anti-Mouse IgG H&L (Alexa Fluor® 488) at 1/1000 dilution (shown in green) and ab150084, Goat polyclonal Secondary Antibody to Rabbit IgG - H&L (Alexa Fluor® 594) at 1/1000 dilution (shown in pseudocolor red). Nuclear DNA was labeled with DAPI (shown in blue).

Immunocytochemistry/ Immunofluorescence - Anti-CHOP antibody [9C8] (AB11419)
ab11419 staining DDIT3 in SK-N-SH (human neuroblastoma cell line) cells treated with deltamethrin (ab141019), by ICC/IF. Increase of DDIT3 expression correlates with increased concentration of deltamethrin, as described in literature.
The cells were incubated at 37°C for 48 hours in media containing different concentrations of ab141019 (deltamethrin) in DMSO, fixed with 100% methanol for 5 minutes at -20°C and blocked with PBS containing 10% goat serum, 0.3 M glycine, 1% BSA and 0.1% tween for 2h at room temperature. Staining of the treated cells with ab11419 (10 μg/ml) was performed overnight at 4°C in PBS containing 1% BSA and 0.1% tween. A DyLight® 488 anti-mouse polyclonal antibody (ab96879) at 1/250 dilution was used as the secondary antibody. Nuclei were counterstained with DAPI and are shown in blue.

Biological function summary
DDIT3 plays a significant role in mediating cellular stress responses and promoting apoptosis when adaptive pathways fail. DDIT3 is not typically part of a multi-subunit complex but it acts in concert with other stress-related proteins to modulate gene expression. By inducing apoptosis DDIT3 helps remove severely damaged cells maintaining overall tissue health. However excessive DDIT3 activity under prolonged stress can lead to cell loss and tissue damage.
Pathways
DDIT3 is involved in the unfolded protein response (UPR) and endoplasmic reticulum stress pathways. It interacts with proteins such as ATF4 and PERK which are part of the mechanism that governs these pathways. DDIT3 induction contributes to the UPR pathway balancing the cell's fate between repair and apoptosis. This balance is important for cell survival under stress and avoids detrimental cellular damage.
