Regulation Of C-Raf Stability By The Ranbpm/Ctlh Complex, Christina J. Mctavish
Regulation Of C-Raf Stability By The Ranbpm/Ctlh Complex, Christina J. Mctavish
Electronic Thesis and Dissertation Repository
RanBPM is an evolutionarily conserved multi-domain protein that has been implicated in the regulation of several cellular process, including protein stability, cell migration, gene transcription, and apoptosis. RanBPM is identified as a key member of the CTLH complex, an orthologous complex to a yeast E3 ubiquitin ligase complex, the exact function of which remains unknown. Previously, our laboratory identified RanBPM as an inhibitor of the ERK1/2 pathway through the modulation of C-RAF protein levels. This study shows that RanBPM-mediated degradation of C-RAF occurs through the proteasome and the entire CRA domain of RanBPM is necessary for direct interaction with C-RAF …
Building Muscle: The Role Of Insulin-Like Growth Factor Binding Protein-6 And Insulin-Like Growth Factors In The Differentiation Of Placental Mesenchymal Stem Cells Into Skeletal Muscle, Doaa Aboalola
Electronic Thesis and Dissertation Repository
Human placenta is a readily available source for isolation of adult mesenchymal stem cell (MSC), for potential use in regenerative therapies. MSC fate is influenced by the microenvironment in vivo, and insulin-like growth factors (IGFs) are critical components of the stem cell niche, as they regulate proliferation and differentiation into different lineages including bone, fat, and skeletal muscle. Insulin-like growth factor binding protein-6 (IGFBP-6), relative to other IGFBPs, has high affinity for IGF2 and is believed to be the main modulator of IGF-2 function. However, the role of IGFBP-6 in muscle development has not been clearly defined. In this …
Pulmonary Surfactant Fortified With Cath-2 As A Novel Therapy For Bacterial Pneumonia, Brandon J. Baer
Pulmonary Surfactant Fortified With Cath-2 As A Novel Therapy For Bacterial Pneumonia, Brandon J. Baer
Western Research Forum
Background: Bacterial pneumonia is a leading cause of death worldwide, with high mortality rates persisting even after antibiotic treatment. Current treatments for pneumonia involve administration of antibiotics, however after the bacteria are killed they release toxic substances that induce inflammation and lung dysfunction. Host defense peptides represent a potential solution to this problem through their ability to down regulate inflammation. However, effective delivery to the lung is difficult because of the complex branching structure of the airways. My study addresses this delivery problem by using exogenous surfactant, a pulmonary delivery vehicle capable of improving spreading of these peptides throughout the …
The Effects Of Acetylenic Tricyclic Bis-(Cyano Enone) On Cell Migration, Eddie Chan
The Effects Of Acetylenic Tricyclic Bis-(Cyano Enone) On Cell Migration, Eddie Chan
Electronic Thesis and Dissertation Repository
Although cancer survival rates have significantly improved over the past few decades, the improvements are primarily due to early diagnosis and inhibiting cancer growth. Limited progress has been made in the treatment of cancer metastasis, which contributes to 90% of cancer related deaths, and therapeutic agents targeting the various aspects of metastasis are lacking. One potential approach is to utilize small pharmacological compounds to inhibit tumour cell motility, as a strategy against tumour cell migration, invasion, and metastasis. The acetylenic tricyclic bis-(cyano enone), TBE-31, has been shown to be a promising chemopreventative compound. However, its effects on cell migration are …
