Oncology reports, 2007•spandidos-publications.comHuman breast cancer cell line SKBR3 expresses high level of the ErbB2 molecule, which
has been associated with poor prognosis of breast cancer. Elevated ErbB2 functions as a
transactivating co-receptor and promotes the formation of ErbB2 containing heterodimers,
which are more mitogenic and transforming, and have a higher ligand affinity and signaling
potency by virtue of the potent latent kinase activity of ErbB2. Interestingly, SKBR3 cells are
non-tumorigenic in nude mice. By ectopic overexpression of c-Jun in SKBR3 cells …

Human breast cancer cell line SKBR3 expresses high level of the ErbB2 molecule, which has been associated with poor prognosis of breast cancer. Elevated ErbB2 functions as a transactivating co-receptor and promotes the formation of ErbB2 containing heterodimers, which are more mitogenic and transforming, and have a higher ligand affinity and signaling potency by virtue of the potent latent kinase activity of ErbB2. Interestingly, SKBR3 cells are non-tumorigenic in nude mice. By ectopic overexpression of c-Jun in SKBR3 cells, involvement of c-Jun in invasiveness and metastasis in vivo was investigated in this study. The critical role of c-Jun in the tumorigenesis and metastasis is demonstrated in nude mice.
