FoxO1/FKHR in LNCaP Human Cell Line. FoxO1/FKHR was detected in immersion fixed LNCaP human prostate cancer cell line using Human FoxO1/FKHR Monoclonal Antibody (Catalog # MAB5939) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red, upper panel; Catalog # NL007) and counterstained with DAPI (blue, lower panel). Specific staining was localized to nuclei. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

FoxO1, also called FKHR (forkhead in rhabdomyosarcoma), is a 655 amino acid (aa), 70 kDa, ubiquitously expressed member of the forkhead box O family of winged helix transcription factors. In neurons, it is activated in response to stress, translocating to the nucleus where it promotes apoptosis and blocks proliferation. In insulin-responsive tissues, nutrient abundance triggers phosphorylation by AKT that blocks nuclear translocation and activity. A 60 kDa form, cleaved at R537, has been found in androgen-treated prostate cancer cells. Over aa 353-655, human FoxO1 shares 93% aa identity with mouse and rat FoxO1.
