2ME2 increases p65 nucleolar localization in LNCaP cells. Double immunofluorescence showing localization of p65 to the nucleolus in LNCaP cells treated with 2ME2 for 24 h. In control LNCaP cells, p65 (green) is cytoplasmic, nucleolin (red) is in the nucleolus, DAPI (blue) stains the nucleus, and the merge of p65/nucleolin/DAPI shows no co-localization of p65 and nucleolin or DAPI. In 2ME2 treated LNCaP cells, p65 remains mostly cytoplasmic but some is localized within the nucleus; nucleolin is localized to the cytoplasm and some remains in the nucleolus or nucleus; DAPI shows mitotic cells. The merge of p65/nucleolin/DAPI shows some cells (arrows 1) with co-localized p65/nucleolin within the nucleolus (white) and within the cytoplasm (yellow). Also shown is a cell (arrow 2) with no co-localization of p65 and nucleolin. (×200).
