Figure 3

Comparison of the effect of antihormones on the RNA expression of the nine human LIV-1 family members. MCF-7 cells were treated with 4-hydroxytamoxifen (TAM), fulvestrant (FAS), or oestradiol (E2) for seven days in serum growth factor-free DCCM medium before total RNA was extracted, reverse transcribed to cDNA, and PCR performed for individual ZIPs. All data were normalized to individual β-actin levels. The upper panel shows representative agarose gels of pS2, LIV-1, HKE4, and ZIP8 in MCF-7 treated with oestradiol (lane 1), untreated (lane 2), treated with Tamoxifen (lane 3), or treated with Fulvestrant (lane 4). M represents size markers. Lower panel shows mean ± SEM densitometric values of 8 genes, comparing their expression levels in MCF-7 cells untreated (CON), or treated with oestradiol (E2), Tamoxifen (TAM), or Fulvestrant (FAS). Statistically significant results are indicated with asterisks, and the relevant P value is given. ZIP4 was undetectable.
