MTSV1-7 CE1

Cell Line Origin

Breast cancer, morphogenesis, adhesion properties

Cell Line Description

MTSV1-7 CE1 is a clonal derivative of the human mammary luminal epithelial cell line MTSV1-7 transfected with ERBB2 expression vector, enabling the over-expression of ERBB2 proto-oncogene. Cultures of MTSV1-7 were transfected with the pSV2-erbB2 construct together with the pSV2neo plasmid. (See also 1-7HB2 Sigma catalog number 10081201).

The MTSV1-7 CE1 cell line is an ideal tool for investigation of the role of the ERBB2 receptor proto-oncogene in breast cancer morphogenesis and adhesion. MTSV1-7 CE1 cells over-express the ERBB2 receptor, inducing a reduced ability to undergo morphogenesis in vitro, and reduced expression of surface adhesion molecules E-Cadherin and alpha-2 integrin. Inhibition of morphogenesis and transcription of adhesion molecules in human mammary epithelial cells can be affected by signals generated by the ERBB2 receptor, suggesting a role for ERBB2 over-expression in tumour progression and metastasis.
