Altered Lipid Metabolism And Adipocyte Activity Support Her2+ Breast Cancer Progression, Jason Wong
Altered Lipid Metabolism And Adipocyte Activity Support Her2+ Breast Cancer Progression, Jason Wong
Legacy Theses & Dissertations (2009 - 2024)
Overexpression of HER2 (ERBB2/neu) in breast cancer is an established clinical marker for aggressive disease and increased mortality. HER2+ breast cancers have increased protein levels of Human Epidermal Growth Factor Receptor 2 and overexpression of its coding gene, ERBB2. Many HER2+ tumors feature concomitant co-expression of the Nuclear Receptor subfamily 1, Group D, Member 1 (NR1D1/RevERBα) which regulates adipogenesis and circadian rhythm; the dysregulation of these two processes are known risk factors for breast cancer. HER2+ breast cancer cells have increased lipid synthesis, with evidence suggesting that NR1D1 is responsible for the upregulation of several genes in the de novo …

The transcription factor NF-κB plays a central role in many aspects of biological processes and diseases, such as inflammation and cancer. Although it has been suggested thatNF-κB is critical in tumorigenesis and tumor progression, the molecular mechanism by which NF-κB is activated in solid tumor remains largely unknown. In the current work, we focus on growth factor receptor-induced NF-κB activation and tumor progression, including epidermal growth factor receptor (EGFR)-induced NF-κB in lung cancer and heregulin receptor (HER2)-induced NF-κB in breast cancer. We found that Mucosa-associated lymphoma translocation protein 1 (MALT1), also known as paracaspase, is required for EGFR-induced NF-κB activation …
An Rnai Screen Targeting The Protein Tyrosine Kinases Identifies Bruton's Tyrosine Kinase (Btk) As A Breast Cancer Cell Survival Factor, Cheryl Lynne Eifert
An Rnai Screen Targeting The Protein Tyrosine Kinases Identifies Bruton's Tyrosine Kinase (Btk) As A Breast Cancer Cell Survival Factor, Cheryl Lynne Eifert

The receptor protein tyrosine kinases (RPTKs) and the non- receptor protein tyrosine kinases (PTKs) are among the most commonly up-regulated genes found in all types of cancers. Although, a large body of data implicates a majority of tyrosine kinases (TKs) in cancer, few have been extensively evaluated for any potential therapeutic benefit in any of the many subtypes of breast cancer. We have used RNA interference (RNAi) to perform a large-scale loss-of-function analysis to facilitate the identification of individual factors necessary for the survival of an ErbB2 positive breast cancer cell line. We have found that 30% of the TKs …
