Protease Oma1 Modulates Mitochondrial Bioenergetics And Ultrastructure Through Dynamic Association With Micos Complex, Martonio P. Viana
Protease Oma1 Modulates Mitochondrial Bioenergetics And Ultrastructure Through Dynamic Association With Micos Complex, Martonio P. Viana
Department of Biochemistry: Dissertations, Theses, and Student Research
Remodeling of mitochondrial ultrastructure is a complex dynamic process that is critical for a variety of mitochondrial functions and apoptosis. Although the key regulators of this process - mitochondrial contact site and cristae junction organizing system (MICOS) and GTPase Optic Atrophy 1 (OPA1) have been characterized, the mechanisms behind this regulation remain incompletely defined. Here, we found that in addition to its role in mitochondrial division, metallopeptidase OMA1 is required for maintenance of contacts between the inner and outer membranes through a dynamic association with MICOS. This association is independent of OPA1, appears to be mediated via the MIC60 MICOS …
Novel Regulatory Roles Of Endocytic Membrane Trafficking Proteins In Mitochondrial Homeostasis, Trey Farmer
Novel Regulatory Roles Of Endocytic Membrane Trafficking Proteins In Mitochondrial Homeostasis, Trey Farmer
Theses & Dissertations
Endocytic membrane trafficking is a basic cell process that is critical for regulating the transport of lipids and proteins. Our lab focuses on the cellular functions and mechanisms of the proteins that regulate these pathways. A key family of regulatory proteins is the C-terminal Eps15 Homology Domain (EHD) protein family. The EHD family includes EHD1-4, which are ubiquitously expressed in mammalian tissues. While these isoforms do have some overlapping functions, each protein also has distinct activities in regulating the shape and fission of membranes throughout the endocytic pathways. Specifically, EHD1 uses ATP hydrolysis to induce constriction and fission of endocytic …
Novel Cyanoximates As An Alternative In Cancer Chemotherapy, Kafayat Aderonke Yusuf
Novel Cyanoximates As An Alternative In Cancer Chemotherapy, Kafayat Aderonke Yusuf
MSU Graduate Theses
Chemotherapy is one of the most effective treatment plans for several cancer types. The recurrent side effects derived from chemotherapy agents have warranted the search for novel chemical compounds with better efficacy and minimal side effects. In line with this idea, I investigated effects of a group of newly synthesized metal based chemical compounds called cyanoximates on HeLa human cancer cells. Cyanoximates used were Pt(DECO)2, Pt(MCO)2, and Pd(DECO)2 along with the chemotherapy drug cisplatin as a positive control. I found that the metal cyanoximates reduced cell viability via apoptosis, and that Pt(DECO)2 was most …
Synthesized Tripodal Amine As Potential Anti-Cancer Therapeutic, Abigail G. Mcnamee
Synthesized Tripodal Amine As Potential Anti-Cancer Therapeutic, Abigail G. Mcnamee
Honors College Theses
Cancer remains a prevalent disease today. This disease may manifest itself in many different ways and affect a variety of tissues with everything from the brain to the blood. With this wide diversity of cancer types, treatment can be complicated since there is not a “one size fits all” treatment for the disease. Surgery, radiation, and chemotherapy are all options that must be weighed with their benefits and side effects. Ultimately though, there are not enough effective treatment options available for every type of cancer. This leaves many with the grim prognosis of never being cured. With this clear need …

Evaluating The Anti-Cancer Efficacy Of A Synthetic Curcumin Analog On Human Melanoma Cells And Its Interaction With Standard Chemotherapeutics, Krishan Parashar, Siddhartha Sood, Ali Mehaidli, Colin Curran, Caleb Vegh, Christopher Nguyen, Christopher Pignanelli, Jianzhang Wu, Guang Liang, Yi Wang, Siyaram Pandey
Medical Student Research Symposium
Melanoma is the leading cause of skin-cancer related deaths in North America. Metastatic melanoma is difficult to treat and chemotherapies have limited success. Furthermore, chemotherapies lead to toxic side effects due to nonselective targeting of normal cells. Curcumin is a natural product of Curcuma longa (turmeric) and has been shown to possess anti-cancer activity. However, due to its poor bioavailability and stability, natural curcumin is not an effective cancer treatment. We tested synthetic analogs of curcumin that are more stable. One of these derivatives, Compound A, has shown significant anti-cancer efficacy in colon, leukemia, and triple-negative inflammatory breast cancer cells. …
