The binding of WNT to its seven-pass membrane receptor Frizzled (FZD) transactivates EGFR. The mechanism seems to be similar to that described for GPCRs, as it is rapid and blocked by metalloproteinase inhibitors; however, the target ligand has not been identified. WNT?FZD-mediated transactivation has been observed in normal mammary cells43 and in breast cancer cells (T. Schlange and N.E.H., unpublished observations). Oestradiol (E2) bindingto plasma-membrane-associated oestrogen receptor (ER) has also been shown to rapidly transactivate ERBBs. According to one report, E2-stimulated activation of MMP2 and MMP9 leads to the release of HB-EGF. Tamoxifen, a selective ER modifier (SERM) was shown to transactivate EGFR and ERBB2, and in ERBB2-overexpressing breast cancer cells this reduced the antiproliferative activity of the SERM"; prov:wasQuotedFrom pubmed:15864276 . sub:_7 rdfs:label "Selventa" . sub:assertion prov:hadPrimarySource pubmed:15864276; prov:wasDerivedFrom beldoc:, sub:_6 . } sub:pubinfo { this: dct:created "2014-07-03T14:30:34.883+02:00"^^xsd:dateTime; pav:createdBy orcid:0000-0001-6818-334X, orcid:0000-0002-1267-0234 . }
