Erbb3 Signaling And Its Effect On Spheroid Formation In Ovarian Cancer, Muskan Bansal, Danielle Burke, Mara P. Steinkamp

AUCTUS: The Journal of Undergraduate Research and Creative Scholarship

ErbB3 is a receptor tyrosine kinase in the epidermal growth factor receptor (EGFR) family. Like other family members, it has an extracellular ligand-binding domain, a transmembrane domain, and an intracellular kinase domain. ErbB3 requires interactions with other receptors and dimerizes with ErbB2 and MET, to activate downstream signaling pathways. Mutations in the ErbB3 gene within the extracellular and kinase domains have been identified in many cancer types. To understand the impact of ErbB3 on cancer growth and metastasis, the human ovarian cancer cell line, OVCAR8, was used as a model. Parental OVCAR8 cells that express ErbB2 and ErbB3 were compared …

Inhibition Of Nuclear Factor-Kappa B Enhances The Tumor Growth Of Ovarian Cancer Cell Line Derived From A Low-Grade Papillary Serous Carcinoma In P53-Independent Pathway, Xue Xiao, Gong Yang, Peng Bai, Shunping Gui, Tri M. Bui Nguyen, +8 Additional Authors

Biochemistry and Molecular Medicine Faculty Publications

Background: NF-kB can function as an oncogene or tumor suppressor depending on cancer types. The role of NF-kB in low-grade serous ovarian cancer, however, has never been tested. We sought to elucidate the function of NF-kB in the low-grade serous ovarian cancer.

Methods: The ovarian cancer cell line, HOC-7, derived from a low-grade papillary serous carcinoma. Introduction of a dominant negative mutant, IkBαM, which resulted in decrease of NF-kB function in ovarian cancer cell lines. The transcription ability, tumorigenesis, cell proliferation and apoptosis were observed in derivative cell lines in comparison with parental cells.

Results: Western blot analysis indicated increased …

Intake Of Coffee And Tea And Risk Of Ovarian Cancer: A Prospective Cohort Study, Stephanie A. Navarro Silvera, Meera Jain, Geoffrey R. Howe, Anthony B. Miller, Thomas E. Rohan

Department of Public Health Scholarship and Creative Works

There is some evidence from case-control studies that coffee consumption might be positively associated with ovarian cancer risk, whereas the epidemiologic evidence regarding tea consumption and ovarian cancer is inconsistent. To date, there have been few prospective studies of these associations. Therefore, we examined ovarian cancer risk in association with both coffee and tea intake in a prospective cohort study of 49,613 Canadian women enrolled in the National Breast Screening Study (NBSS) who completed a self-administered food frequency questionnaire between 1980 and 1985. Linkages to national mortality and cancer databases yielded data on deaths and cancer incidence, with follow-up ending …

Outpatient Administration Of Paclitaxel, Siu Fun Wong

Pharmacy Faculty Articles and Research

Paclitaxel (Taxol®, Bristol-Meyers Squibb), anti neoplastic agent made from the bark of the Pacific yew tree, is undoubtedly one of the most exciting agents to be evaluated over the past decade. Paclitaxel has demonstrated significant promise against ovarian and metastatic breast cancer, and appears to be the most effective single agent to date for non-small-cell lung cancer in trials conducted by Eastern Cooperative Oncology Group (ECOG).
