(Submitter supplied) Recent studies have identified clinical subtypes of breast tumors that arise from different cell types and have different outcomes in response to chemotherapy. Tumors derived from basal epithelium have a poorer prognosis than tumors derived from luminal epithelium. To gain insight into differences underlying this disparity, we treated cell lines derived from basal epithelium (immortalized human mammary epithelial cells) and those derived from luminal epithelium (MCF-7 and ZR-75-1) with two chemotherapeutics commonly used in the treatment of breast cancer. more...

(Submitter supplied) Global gene expression profiling has demonstrated that the predominant cellular response to a range of toxicants is a general stress response. This stereotyped environmental stress response commonly includes repression of protein synthesis and cell cycle regulated genes and induction of DNA damage and oxidative stress responsive genes. Our laboratory has recently characterized the general stress response of breast cell lines derived from basal-like and luminal epithelium following treatment with doxorubicin (DOX) or 5-fluorouracil (5FU) and showed that each cell type has a distinct response. more...

Analysis of 4 breast cell lines treated for up to 36 hrs with the chemotherapeutic agents 5-fluorouracil (5FU), doxorubicin (DOX), or etoposide (ETOP), a drug mechanistically similar to DOX. Expression profiles for DOX- and 5FU-treated cells were used to successfully predict the response to ETOP.

(Submitter supplied) Anti-estrogens and aromatase inhibitors are important drugs in the treatment of estrogen-dependent breast cancer. In order to investigate the effects of these drugs on gene expression in breast cancer cells, we treated estrogen receptor-positive MCF-7 cells, stably transfected with the aromatase gene (known as MCF-7aro cells), with testosterone, 17β-estradiol, two aromatase inhibitors (letrozole and anastrozole), and an anti-estrogen (tamoxifen). more...

(Submitter supplied) Breast cancer subtypes identified in genomic studies have different underlying genetic defects. Mutations in the tumor suppressor p53 occur more frequently in estrogen receptor (ER) negative, basal-like and HER2-amplified tumors than in luminal, ER positive tumors. Thus, because p53 mutation status is tightly linked to other characteristics of prognostic importance, it is difficult to identify p53's independent prognostic effects. more...

(Submitter supplied) Treatment-related morbidities have been linked to the large post-operative treatment volumes required for external beam partial breast irradiation (PBI). Alternative PBI techniques require equipment that is not readily available. To address these issues, we designed a phase I trial utilizing widely available technology to 1) evaluate the safety of a single radiation treatment delivered preoperatively to the small-volume, intact breast tumor and 2) identify imaging and genomic markers of radiation response.

(Submitter supplied) Introduction: Breast radiotherapy is currently “one size fits all” regardless of breast cancer subtype (eg. luminal, basal). However, recent clinical data suggests that radiation response may vary significantly among subtypes. Therefore, current practice leads to over- or under-treatment of women whose tumors are more or less radiation responsive. We hypothesized that this clinical variability may be due, in part, to differences in cellular radiation response. more...

(Submitter supplied) Doxorubicin is considered one of the most potent established chemotherapeutics in the treatment of liposarcoma; however, the response rates usually below 30%, are still disappointing. This study was performed to identify gene expression changes in liposarcoma after doxorubicin treatment. Cells of 19 primary human liposarcoma were harvested intraoperatively and brought into cell culture. Cells were incubated with doxorubicin for 24 h, RNA was isolated and differential gene expression was analysed by the microarray technique. more...
