Cellular Uptake Of Neutrohpil Elastase Links Inflammation To Adaptive Immunity, Elizabeth A. Mittendorf Dec 2012

Cellular Uptake Of Neutrohpil Elastase Links Inflammation To Adaptive Immunity, Elizabeth A. Mittendorf

Dissertations & Theses (Open Access)

Many tumors arise from sites of inflammation providing evidence that innate immunity is a critical component in the development and progression of cancer. Neutrophils are primary mediators of the innate immune response. Upon activation, an important function of neutrophils is release of an assortment of proteins from their granules including the serine protease neutrophil elastase (NE). The effect of NE on cancer has been attributed primarily to its ability to degrade the extracellular matrix thereby promoting invasion and metastasis. Recently, it was shown that NE could be taken up by lung cancer cells leading to degradation of insulin receptor substrate-1 …


Regulation Of Net1a Subcellular Localization By The Small Gtpase Rac1, Christopher A. Morris May 2012

Regulation Of Net1a Subcellular Localization By The Small Gtpase Rac1, Christopher A. Morris

Dissertations & Theses (Open Access)

Activation of Rho family small G proteins is thought to be a critical event in breast cancer development and metastatic progression. Rho protein activation is stimulated by a family of enzymes known as guanine nucleotide exchange factors (Rho GEFs). The neuroepithelioma transforming gene 1 (Net1) is a Rho GEF specific for the RhoA subfamily that is overexpressed in primary breast tumors and breast cancer cell lines. Net1 isoform expression is also required for migration and invasion of breast cancer cells in vitro. These data indicate that Net1 may be a critical regulator of metastatic progression in breast cancer. Net1 activity …
