Abstract
An epithelial cell line, referred to as A163, was established from
breast carcinoma derived from a patient with a strong family history
of breast cancer but no known breast cancer susceptibility mutation.
A163 was propagated in a serum-free culture medium including the
epidermal growth factor. Immunophenotypic characterization
demonstrated a mixed luminal and basal-like phenotype. When epidermal
growth factor was excluded from the culture medium, A163 entered a
quiescent period followed by a period of increased cell proliferation
in a subpopulation of the cells. The epidermal growth factor-
independent subpopulation retained the basal-like phenotype of the
parental cell line. Karyotype and fluorescent in situ hybridization
analysis showed an amplification of epidermal growth factor receptor
on 7q in A163-S1 only, resulting in high expression of total and
phosphorylated epidermal growth factor receptor. The A163-S1 sub-line
piles up in culture, indicating a loss of contact inhibition. When
grown on transwell filters, A163 shows basal expression of P63 and
cytokeratin 14, whereas A163-S1 expresses P63 ubiquitously, and has
lost the basal specific expression of cytokeratin 14, indicating a
loss of polarity. Furthermore, when cultured in reconstituted basement
membrane matrix, A163 form polarized normal like acini. In contrast,
A163-S1 form large disorganized structures with lack of polarity.
These cell lines may prove useful to understand molecular changes in
breast cancer progression, in particular basal-like breast cancer
subtype with bad prognosis and no current treatment options.
