Dataset: Transcription profiling of human breast tumor epithelia cell types HMLER and BPLER compared to immortalized parent cells of origin - HME and BPE

The gene expression of two different tumorigenic human breast epithelial cell types (HMLER and BPLER) is compared with their immortalized parental cell-of-origin (HME and BPE). Experiment Overall Design: Two different normal primary human mammary epithelial cell populations (BPECs and HMECs) were isolated based on their differing in vitro growth requirements. These cells were immortalized by hTERT giving rise to BPE and HME cells. These hTERT immortalized cells (BPE and HME) were transformed by SV40-early region (LT+st) and H-Ras giving rise to transformed tumorigenic derivatives BPLER and HMLER. Biological replicates (4 - 6 samples) for each of 4 cell types were analyzed (untransformed hTERT immortalized cell populations (BPE&HME), and transformed tumorigenic derivatives (BPLER & HMLER).
