Requirements Of Rab5 Activity In Highly Invasive Breast Cancer Cell Lines, Nicole Porther, M Alejandro Barbieri Dec 2013

Requirements Of Rab5 Activity In Highly Invasive Breast Cancer Cell Lines, Nicole Porther, M Alejandro Barbieri

Nicole Porther

Rab5 expression in cancer has been associated with the disease progression and prognosis. We have previously shown that growth factor-directed cell invasion and migration was dependent on Rab5 activation in non-invasive breast cancer cells. However, hardly any data is available regarding the role of Rab5 in invasive cells in the presence of growth factor.  In our present study, we report that the invasive and migratory properties of the highly invasive breast cancer cell line, MDAMB-231, were abrogated in cells expressing the inactive (GDP-bound) form of Rab5 irrespective of growth factor stimulation; while the invasive potential of breast cancer cell lines ...


Rab5 Function In Breast Cancer Cells, Nicole Porther, M Alejandro Barbieri Dec 2012

Rab5 Function In Breast Cancer Cells, Nicole Porther, M Alejandro Barbieri

Metastasis is characterized pathologically by cell invasion, proliferation, migration and angiogenesis. Growth factors, which include epithelial growth factor (EGF), insulin growth factors I and II (IGFI and IGFII); have been associated with most if not all of the features of metastasis.  Our study has highlighted the possible role growth factors may have in mediating cancer metastasis via Rab GTPses.  We determined that the invasive and migratory properties of breast cancer cells were abrogated in cell lines that only expressed the inactive (GDP-bound) form of Rab 5 irrespective of growth factor stimulation. Breast cancer cell lines expressing the wild type and ...

An Entrepreneurial Approach To Librarianship, Flora G. Shrode, Jennifer R. Duncan, Wendy Holliday Apr 2010

An Entrepreneurial Approach To Librarianship, Flora G. Shrode, Jennifer R. Duncan, Wendy Holliday

Librarians from Utah State University explain recent efforts to encourage subject librarians to take a more holistic view of their roles. We are shifting from a traditional emphasis primarily on collection development and refocusing on natural connections between collections, instruction, liaison, and reference service. The poster provides background about Utah State University’s situation and explains our approach to analyzing local needs and culture to inform development of a new organizational structure. We describe our vision of subject librarianship, the process by which we assessed librarians’ ideas and goals for performing as subject librarians, and the actions we are taking ...
