Transcriptomic analysis of mammary tumor biospy from MMTV-ErbB2 transgenic mice [Doxorubicin]

Project description:The tyrosine kinase ErbB2 positive breast tumors have more aggressive tumor growth, poorer clinical outcome, and more resistance to radiotherapy, chemotherapy and hormone therapy. To identify the biomarkers for predicting the responses to chemotherapy, we treated genetically diverse F1 backcross (F1Bx) mice between C57BL/6J and FVB/N MMTV-Erbb2 transgenic mice with mammary tumor by doxorubicin. Biopsies were taken in sterile conditions and processed for RNA and histological analysis before treatment. This will help us to have a better understanding of the heterogeneous response to chemotherapy and permit us to design better and more individualized (personalized) treatment strategies for human ErbB2 positive breast cancer.

Transcriptomic analysis of mammary tumors from MMTV-ErbB2 transgenic mice

Project description:The tyrosine kinase ErbB2 positive breast tumors have more aggressive tumor growth, poorer clinical outcome, and more resistance to radiotherapy, chemotherapy and hormone therapy. A humanized anti-ErbB2 monoclonal antibody Herceptin and a small molecules inhibitor Lapatinib were developed and approved by FDA to treat patients with ErbB2 amplification and overexpression. Unfortunately, most ErbB2+ breast cancers do not respond to Herceptin and Lapatinib, and the majority of responders become resistant within 12 months of initial therapy (defined as secondary drug resistance). Such differences in response to Lapatinib treatment is contributed by substantial heterogeneity within ErbB2+ breast cancers. To address this possibility, we carried out transcriptomic analysis of mammary tumors from genetically diverse MMTV-ErbB2 mice. This will help us to have a better understanding of the heterogeneous response to ErbB2 targeted therapy and permit us to design better and more individualized (personalized) treatment strategies for human ErbB2 positive breast cancer. 214 MMTV-ErbB2 mammary tumors and 8 normal mammary glands were analyzed by Affymetrix microarrays.

Transcriptomic analysis of mammary tumor biospy from MMTV-ErbB2 transgenic mice [Docetaxlel]

Project description:The tyrosine kinase ErbB2 positive breast tumors have more aggressive tumor growth, poorer clinical outcome, and more resistance to radiotherapy, chemotherapy and hormone therapy. To identify the biomarkers for predicting the responses to chemotherapy, we treated genetically diverse F1 backcross (F1Bx) mice between C57BL/6J and FVB/N MMTV-Erbb2 transgenic mice with mammary tumor by docetaxel. Biopsies were taken in sterile conditions and processed for RNA and histological analysis before treatment. This will help us to have a better understanding of the heterogeneous response to chemotherapy and permit us to design better and more individualized (personalized) treatment strategies for human ErbB2 positive breast cancer.

Comparative Analysis of MMTV-neu tumors, preneoplastic MMTV-neu mammary gland, and Wild-type controls

Project description:To identify early events of erbB2-induced mammary tumorigenesis, we compared datasets from 14 genechip experiments including MMTV-neu tumors, preneoplastic neu mammary gland (adjacent neu), and age-matched, wild-type control mammary glands Keywords = transgenic mouse Keywords = MMTV-neu Keywords = erbB2 Keywords = HER2 Keywords = mammary tumor Keywords: ordered

Expression data from mammary macrophages isolated from MMTV-iFGFR1 transgenic mice

Project description:The goal of this experiment was to profile macrophages from mammary glands isolated from transgenic mice that express inducible FGFR1 in mammary epithelial cells (MMTV-iFGFR1 transgenic mice). The mice were treated with with dimerizer to activates iFGFR1 for 48 hours and 4 weeks to induce mammary hyperplasias. Control mice included non-transgenic littermates treated with dimerizer for the same amount of time. Macrophages were sorted from mammary glands of MMTV-iFGFR1 transgenic mice and non-transgenic mice following dimerizer treatment using Cd11b-PE. Macrophages from 3 mice were pooled for each sample. RNA was extracted and analyzed using the Affymetrix Mouse 2.0 chip.

Comparative analysis of 10 week and 5 week Bitransgenic mice (LH mouse crossed with MMTV-neu mouse)

Project description:To identify genes that may facilitate early steps of ErbB2/Neu-mediated mammary tumorigenesis, we performed comparative microarray analysis of 5- and 10-week bitransgenic mammary glands (LHxMMTV-neu) in triplicate. Keywords: transgenic mouse, erbB2, MMTV-neu, HER2, mammary tumor, breast cancer
