Stressor Overview
The stressor field is a structured data field that can be used to annotate an AOP with standardised terms identifying stressors known to trigger the MIE/AOP. Most often these are chemical names selected from established chemical ontologies. However, depending on the information available, this could also refer to chemical categories (i.e., groups of chemicals with defined structural features known to trigger the MIE). It can also include non-chemical stressors such as genetic or environmental factors.

Chemical Table
The Chemical Table lists chemicals associated with a stressor. This table contains information about the User’s term for a chemical, the DTXID, Preferred name, CAS number, JChem InChIKey, and Indigo InChIKey.To add a chemical associated with a particular stressor, next to the Chemical Table click ‘Add chemical.’ This will redirect you to a page entitled “New Stressor Chemical.’ The dialog box can be used to search for chemical by name, CAS number, JChem InChIKey, and Indigo InChIKey. Searching by these fields will bring forward a drop down list of existing stressor chemicals formatted as Preferred name, “CAS- preferred name,” “JChem InChIKey – preferred name,” or “Indigo InChIKey- preferred name,” depending on by which field you perform the search. It may take several moments for the drop down list to display. Select an entity from the drop down list and click ‘Add chemical.’ This will return you to the Stressor Page, where the new record should be in the ‘Chemical Table’ on the page.To remove a chemical associated with a particular stressor, in the Chemical Table next to the chemical you wish to delete, click ‘Remove’ and then click 'OK.' The chemical should no longer be visible in the Chemical table.

Increase of anti-DNA antibody from autoreactive B cell
BPA as well as E2 and diethylstilbestrol (DES) enhanced anti-Br-RBC autoantibody production by B1 cells in vivo. IgM production by B1 cells in the presence of ED was more prominent on aged BWF1 mice developing lupus nephritis. (Yurino H. 2004).
To examine a direct effect of endocrine disruptors on IgM antibody production by B1 or B2 cells, B1 cells were prepared from peritoneal cells and B2 cells from spleen, B1 or B2 cells were cultured in the presence of endocrine disruptors (E2: 100 nM, DES: 100 nM, BPA: 1 μM) for 4 days (Yurino H. 2004).
In both (NZB×NZW) F1 and MRL/lpr mice, estrogen treatment exacerbates the lupus disease, with augmented levels of autoantibodies against dsDNA and phospholipids as well as formation of circulating immune complexes (Grimaldi CM. 2002, Peeva E. 2000).
Reduced size of the ovarian follicle pool
Diethylstilbestrol (DES) exposure (0.2 an 20 µg/kg, s.c., 1, 3, 5, and 7 dpp, killed 8 dpp) reduced the number of primordial follicles in rats exposed postnatally (Rodríguez et al. 2010)
