1 Estradiol-Induced MMP-9 Expression via PELP1-Mediated Membrane-Initiated Signaling in ERalpha-Positive Breast Cancer Cells. Estradiol proline, glutamate and leucine rich protein 1 Homo sapiens
2 Proline-, glutamic acid-, leucine-rich protein 1 (PELP1) is a novel estrogen receptor (ER) coregulator, demonstrated distinctive characters from other ERalpha coregulators, and has been suggested to be involved in metastasis of several cancers. Proline proline, glutamate and leucine rich protein 1 Homo sapiens
3 Proline-, glutamic acid-, leucine-rich protein 1 (PELP1) is a novel estrogen receptor (ER) coregulator, demonstrated distinctive characters from other ERalpha coregulators, and has been suggested to be involved in metastasis of several cancers. Glutamic Acid proline, glutamate and leucine rich protein 1 Homo sapiens
4 Proline-, glutamic acid-, leucine-rich protein 1 (PELP1) is a novel estrogen receptor (ER) coregulator, demonstrated distinctive characters from other ERalpha coregulators, and has been suggested to be involved in metastasis of several cancers. Leucine proline, glutamate and leucine rich protein 1 Homo sapiens
5 In ERalpha-positive breast cancer, PELP1 overexpression enhanced ruffles and filopodium-like structure stimulated by estradiol (E2) through extranuclear cell signaling transduction hereby increased cell motility. Estradiol proline, glutamate and leucine rich protein 1 Homo sapiens
6 In ERalpha-positive breast cancer, PELP1 overexpression enhanced ruffles and filopodium-like structure stimulated by estradiol (E2) through extranuclear cell signaling transduction hereby increased cell motility. Estradiol proline, glutamate and leucine rich protein 1 Homo sapiens
7 In this study, we investigated the role of PELP1 in E2-induced MMP-9 expression and the underlined mechanism. Estradiol proline, glutamate and leucine rich protein 1 Homo sapiens
8 Knocked down PELP1 significantly suppressed E2-induced MMP-9 expression. Estradiol proline, glutamate and leucine rich protein 1 Homo sapiens
9 E2-bovine serum albumin (BSA), a large molecular membrane-impenetrable conjugate of E2, can also upregulate MMP-9 protein expression in MCF-7, and the action of E2-BSA can be abolished by PI3K inhibitor LY294002; treating MCF-7 simultaneously with PELP1-shRNA and LY294002 did not show synergetic inhibitory effect on E2-BSA-induced MMP-9 expression. Estradiol proline, glutamate and leucine rich protein 1 Homo sapiens
