   Finding BioAssay Data: Estrogen receptor binding hormones

Launch guide window Launch NCBI Home Page

Goals

  • Find BioAssays that target estrogen receptors
  • Find a population of analogs for estrogen, tamoxifen and testosterone in PubChem Compounds
  • Using the assays, display estrogen receptor binding activity for these compounds

Steps

  1. Find confirmatory BioAssays that target estrogen receptors
    • On the NCBI home page, select PubChem BioAssay from the Database menu, enter "estrogen receptor"[proteintargetname] in the search box and click Go.
    • Select PubChem BioActivity Summary from the Display menu.
    • Select the Confirmatory assays from the list (check the boxes to their left).
    • Click the Data Table tab at the top of the page.

  2. Retrieve PubChem Compound records for estrogen, tamoxifen and testosterone
    • Open a new tab or window in your web browser, and navigate to the NCBI home page.
    • Select PubChem Compound from the Database menu, enter estrogen OR tamoxifen OR testosterone in the search box and click Go.
    • Click the Limits tab, and select Synonym from the All Fields menu. Click Go.

  3. Retrieve assay data for these compounds
    • Go back to your browser tab/window that contains the assay data table you generated before.
    • Click the Select tab from the second row of tabs.
    • Scroll down to the Other Filters section, and click the + next to Compound Filter.
    • Select your estrogen OR tamoxifen OR testosterone query from the PubChem Compound Entrez History menu.
    • Click the Show button at the bottom of the page.

  4. Analyze the results
    • Which compounds were tested? (Click on their CID/SID to find out.) Which ones are active? Inactive?
    • In which assay(s) were these compounds studied?
    • To download the data table, click on the Download button and follow the directions.
