1 Emerging studies suggest that in addition to the nuclear localization of PELP1, it is predominantly localized in the cytoplasm in human breast tumors, leading to excessive nongenomic signaling and possibly to tamoxifen resistance. Tamoxifen proline, glutamate and leucine rich protein 1 Homo sapiens
2 We found that clones of MCF-7 human breast cancer cells overexpressing PELP1 in the cytoplasm were distinctly sensitive to TNF-alpha-induced apoptosis than were wild-type nuclear PELP1- and pcDNA vector-expressing clones as revealed by cell growth assay, cell cycle analysis, Annexin V staining, and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling assay. deoxyuridine triphosphate proline, glutamate and leucine rich protein 1 Homo sapiens
