Gonadotropin Concentrations, Follicular Development, And Luteal Function In Pituitary Stalk-Transfected Ewes Treated With Bovine Follicular Fluid, G. Larson, David Mallory, R. Dailey, P. Lewis
Gonadotropin Concentrations, Follicular Development, And Luteal Function In Pituitary Stalk-Transfected Ewes Treated With Bovine Follicular Fluid, G. Larson, David Mallory, R. Dailey, P. Lewis
David S. Mallory
Two experiments, each arranged as a 2 x 2 factorial, were conducted in ewes to examine direct effects of bovine follicular fluid (bFF) on follicular development and luteal function and to further characterize follicular development and luteal function after pituitary stalk transection (SS). In Exp. 1, ewes were sham-operated or SS on d 6 of an estrous cycle and received 5 ml of saline or bFF three times daily on d 5 through 11 of the same cycle. In Exp. 2, all ewes were SS on d 6 of an estrous cycle and treated with saline or bFF three times …
Intracellular Expression Of An Ice Nucleation Protein Reduces Cryoinjury In Insect Cells, Avril M. Harder
Intracellular Expression Of An Ice Nucleation Protein Reduces Cryoinjury In Insect Cells, Avril M. Harder
Student Honors Theses
Exposure of insect cells to subzero temperatures typically leads to cell membrane disruption and lethal intracellular ice formation. This study seeks to examine the cryoprotective value of trangenically expressing a bacterial ice nucleation protein (INP) in Spodoptera frugiperda (Sf-21) cells. The bacterium Pseudomonas syringae naturally produces a membrane-bound INP (inaZ), capable of structuring water and initiating ice formation at temperatures as high as -2 °C. I hypothesized that intracellular expression of an altered form of inaZ (PsINP) in Sf-21 cells will mediate highly regulated ice nucleation when cells are cooled to -80 °C in a slow, controlled manner, …
Investigating The Mechanism Of Nur77-Induced Apoptosis In T Cells, Heather E. Fogarty
Investigating The Mechanism Of Nur77-Induced Apoptosis In T Cells, Heather E. Fogarty
Masters Theses 1911 - February 2014
Nur77 is a member of the orphan nuclear receptor family, where it is known to play an important role in apoptosis in both negative selection in T cells and in cancer cell lines. In the development of T cells, it is critical for the immune system to discriminate self from non-self by eliminating auto-reactive cells. It was originally thought that Nur77 initiated apoptosis by activating downstream gene targets. However, it is now clear that Nur77 has its own distinct role outside of the nucleus and the precise mechanisms by which Nur77 induces apoptosis in T cells still needs to be …
