TRα1 co-localizes with ubiquitin upon T3 stimulation.

<p>BRCA1 competent MCF7 were co-stained for TRα1 (green signal) and ubiquitin (Ubq, red signal). TRα1 was located in the nucleus (DNA: blue signal) of untreated MCF7 (A, C). The red channel was slightly enhanced in B, C thus to show the faint Ubq signal of un-stimulated MCF7 (B, C). In BRCA1 competent MCF7 co-localization of TRα1 and Ubq was observed in samples stimulated with T3 (D-F, magnified in D’-F’). Scale bar in A equals 25 μm applies to A-F, scale bar in D’ equals 12.5 μm applies to D’-F’. Representative images are shown.
