Figure 2From: Stat3 is tyrosine-phosphorylated through the interleukin-6/glycoprotein 130/Janus kinase pathway in breast cancerDifferential signal transducer and activator of transcription 3 (Stat3) phosphorylation in breast cancer-derived cell lines. Nuclear extracts (20 μg) isolated from MCF10A, MCF7, BT474, MDA-MB-435, MDA-MB-MD-468, and MDA-MB-MD-231 cell lines were analyzed by Western blotting with tyrosine-phosphorylated Stat3 (pStat3) and Stat3 antibodies.Back to article page
