Regenerative Potential Of Mesenchymal Stem Cell Derived Exosomes, Andrew P. Wong
Regenerative Potential Of Mesenchymal Stem Cell Derived Exosomes, Andrew P. Wong
Theses and Dissertations
Bone defects are a pervasive complication arising from many clinical conditions, both mechanical and pathological. Current treatments for large bony defects focus on applying bone grafts or synthetic materials to the defect area. Cell-based—and especially stem-cell—therapies have advanced greatly thanks to increasing attention focused on their ability to generate new tissues in situ with biomechanical properties approaching that of native tissue, but they suffer from their own shortcomings as well. Exosomes have been shown to play critical roles in cell-signaling and tissue regeneration and are therefore potentially ideal therapeutic vehicles for treating bone defects. Exosomes are small microvesicles counted amongst …

Over 200,000 cases of breast cancer are diagnosed every year. Nearly 20% of these patients supplement their diets with some form of vitamin D. This high frequency of vitamin D supplement use may be due in part to research suggesting that cancer patients with higher serum vitamin D3 levels have better prognoses than patients with low serum vitamin D3. However, double-blind clinical trials on the efficacy of vitamin D3 supplementation in breast cancer have been inconclusive. A recent meta-analysis showed evidence of reduced cancer recurrence in patients taking vitamin D3 supplements who had ‘estrogen receptor positive’ …

Cancer involves the dysregulated proliferation and growth of cells throughout the body. C-terminal binding proteins (CtBP) 1 and 2 are transcriptional co-regulators upregulated in several cancers, including breast, colorectal, and ovarian tumors. CtBPs drive oncogenic properties, including migration, invasion, proliferation, and survival, in part through repression of tumor suppressor genes. CtBPs encode an intrinsic dehydrogenase activity, utilizing intracellular NADH concentrations and the substrate 4-methylthio-2-oxobutyric acid (MTOB), to regulate the recruitment of transcriptional regulatory complexes. High levels of MTOB inhibit CtBP dehydrogenase function and induce cytotoxicity among cancer cells in a CtBP-dependent manner. While encouraging, a good therapeutic would utilize >100-fold …
