Tnf-Like Weak Inducer Of Apoptosis (Tweak) : Not So Weak After All., Joseph Dekward Mcmillan Iv
Tnf-Like Weak Inducer Of Apoptosis (Tweak) : Not So Weak After All., Joseph Dekward Mcmillan Iv
Electronic Theses and Dissertations
Background: Tumor necrosis factor (TNF)-like weak inducer of apoptosis (TWEAK) is a proinflammatory cytokine belonging to the TNF super family. TWEAK produces a variety of cellular responses through the binding to fibroblast growth factor inducible 14 (Fn14), a member of TNF receptor superfamily. Although Fn14 lacks a death domain, TWEAK has been found to induce apoptosis in some cell types by perturbing the activity of certain pathways such as TNF-receptor signaling. TWEAK is also known to regulate proliferation and differentiation of myogenic cells. We have previously reported that the TWEAK-Fn14 system causes skeletal muscle wasting both in vitro and in …
Identification And Characterization Of The Anticancer Potential Of Indigenous Medicinal Plants Of The Arabian Peninsula, Sameera Omar Mohammed Saeed Balhamar
Identification And Characterization Of The Anticancer Potential Of Indigenous Medicinal Plants Of The Arabian Peninsula, Sameera Omar Mohammed Saeed Balhamar
Theses
Indigenous plant species historically used for their medicinal properties are a tremendous source for bringing newer and safer drugs to the market. A concerted effort is needed to characterize their medicinal potential and identify new molecules that could be exploited in modern medicine. The current study was undertaken to study the anticancer properties of several indigenous plants that are used by the local population of the Arabian Peninsula and beyond for various medicinal purposes. Towards this end, we acquired different plant extracts from five plants, namely Boswellia sacra (BS), Cleome droserifolia (CD), Teucrium muscatensis (TM), Orchadenus arabicus (OA), and Acredocarpus …
Investigation Of Novel Functions For Dna Damage Response And Repair Proteins In Escherichia Coli And Humans, Benjamin A. Hilton
Investigation Of Novel Functions For Dna Damage Response And Repair Proteins In Escherichia Coli And Humans, Benjamin A. Hilton
Electronic Theses and Dissertations
Endogenous and exogenous agents that can damage DNA are a constant threat to genome stability in all living cells. In response, cells have evolved an array of mechanisms to repair DNA damage or to eliminate the cells damaged beyond repair. One of these mechanisms is nucleotide excision repair (NER) which is the major repair pathway responsible for removing a wide variety of bulky DNA lesions. Deficiency, or mutation, in one or several of the NER repair proteins is responsible for many diseases, including cancer. Prokaryotic NER involves only three proteins to recognize and incise a damaged site, while eukaryotic NER …
Modulation Of Cell Death Signaling And Cell Proliferation By The Interaction Of Homoserine Lactones And Paraoxonase 2., Aaron Mackallan Neely
Modulation Of Cell Death Signaling And Cell Proliferation By The Interaction Of Homoserine Lactones And Paraoxonase 2., Aaron Mackallan Neely
Electronic Theses and Dissertations
Pseudomonas aeruginosa produces N-(3-oxododecanoyl)-homoserine lactone (C12) as a quorum-sensing molecule that functions to facilitate bacteria-bacteria communication. C12 has also been reported to affect many aspects of human host cell physiology, including evoking cell death in various types of cells. However, the signaling pathway(s) leading to C12-triggerred cell death remains unclear. To clarify cell death signaling induced by C12, we examined mouse embryonic fibroblasts (MEFs) deficient in one or more caspases. Our data indicate that, unlike most apoptotic inducers, C12 evokes a novel form of apoptosis in cells, probably through the direct induction of mitochondrial membrane permeabilization. Previous studies indicate that …
The Role Of The Intermembrane Domain Of Mulan In Mitophagy And Cell Death, Jared M. Herbert
The Role Of The Intermembrane Domain Of Mulan In Mitophagy And Cell Death, Jared M. Herbert
Honors Undergraduate Theses
Mulan is an E3 ubiquitin ligase and an E3 SUMO ligase embedded in the outer mitochondrial membrane. Mulan plays a major role in various cell processes including cell growth, mitophagy, apoptosis, and mitochondrial dynamics. In addition, its deregulation is involved in the development and progression of several human disorders such as neurodegeneration and heart disease. There are two main discernible domains in Mulan: a large cytoplasmic domain that encodes the RING-finger motif and carries out the catalytic activity of the protein; the second domain of Mulan is exposed to the intermembrane space of mitochondria, and its function remains unknown. This …
