A Literature Review On Thermogenesis As A Prospective Obesity Treatment, Kellyn Sheppard
A Literature Review On Thermogenesis As A Prospective Obesity Treatment, Kellyn Sheppard
Senior Honors Theses
The disease of obesity has quickly escalated from an epidemic to a worldwide pandemic in the last few decades, and viable treatment methods are being investigated with urgency. One such treatment method is increased induction of the thermogenesis pathway that is active in brown adipose tissue. This pathway is typically activated in mammals when they are exposed to cold temperatures for extended periods of time but can also be induced exogenously. Thermogenesis is a metabolically inefficient process that occurs in the mitochondria of a cell, meaning it uses substrate energy without generating ATP. The inefficiency of this process allows excess …
In Vitro Gametogenesis: A Research Timeline And Implications For The Future Of Assisted Reproductive Technology, Nicole Buckley
In Vitro Gametogenesis: A Research Timeline And Implications For The Future Of Assisted Reproductive Technology, Nicole Buckley
Senior Honors Theses
The novel reproductive technology, In Vitro Gametogenesis (IVG), includes the process of obtaining mature viable germ cells from pluripotent stem cells. To do so, embryonic stem cells and induced pluripotent stem cells are specified to primordial germ cells and differentiated to form gametes that undergo further maturation, which subsequently may undergo in vitro fertilization to form an embryo. With this capability, IVG holds the power to provide a novel treatment option for human infertility. As of now, research has been conducted on mice successfully, and with limited success in humans. Future research will likely focus on discovering the species-specific differences …
Investigation Of Oncogenic Ras And Endoplasmic Reticulum-Mitochondria Calcium Flux And Their Relationship In The Context Of Tumorigenesis, Emma Anderson
Senior Honors Theses
Intracellular calcium as a signaling molecule is a pervasive feature of cellular pathways, especially those that manage internal homeostasis and transitions through the cell cycle, so much so that regulated, responsive calcium flux between the endoplasmic reticulum (ER) and the mitochondria has been suggested to play a major role in cancer development. Another factor commonly implicated in tumorigenesis is RAS, an oncogene that controls signaling for many pathways that are also regulated by calcium. While both calcium and oncogenic RAS signaling are implicated in cancer development, possible links between them have yet to be determined. The identification of these links …
An Investigative Analysis Of Underlying Alzheimer’S Disease Pathology: Understanding The Pathology Of Neurofibril Tangles, William Barker
An Investigative Analysis Of Underlying Alzheimer’S Disease Pathology: Understanding The Pathology Of Neurofibril Tangles, William Barker
Senior Honors Theses
Researchers familiar with Alzheimer’s Disease (AD) refer to two common pathological hallmarks: β-amyloid plaques and Neurofibril Tangles (NFTs). The development of these pathologies are the leading theory to explain the cause of cognitive decline and dementia-like symptoms of individuals with AD. The literature supports the theory that NFTs are caused by the hyperphosphorylation of the precursor tau protein. However, the mechanism that causes this hyperphosphorylation is still unknown. This review seeks to evaluate the normal function of tau then analyze and expound upon the current research concerning the underlying mechanisms for the hyperphosphorylation of tau observed in Neurofibril Tangles pathologies. …
Dna Aptamer-Drug Targeting Chemotherapy: Investigation Of Cell Cycle Inhibition Via S15 Aptamer – Norcantharidin Complex, Shannon Fehr
Dna Aptamer-Drug Targeting Chemotherapy: Investigation Of Cell Cycle Inhibition Via S15 Aptamer – Norcantharidin Complex, Shannon Fehr
Senior Honors Theses
Lung Cancer is the leading cause of cancer related death in both men and women in the United States (Bray et al., 2018). Cancer treatments are often non-specific and kill many dividing cells within a patient causing unwanted side effects. Norcantharidin (NCTD) is a synthetic FDA approved treatment for cancers including non-small cell lung cancers (NSCLC). NCTD suppresses cell proliferation by inhibiting cells from exiting the G2 phase of the cell cycle. Aptamers are short single-stranded DNA or RNA molecules with ligand directed self-annealing capabilities allowing selective binding to specific targets. This paper will discuss the hypothesized effects of using …
Genetic Relationships And Therapeutic Options For Relapsed Acute Lymphoblastic Leukemia, Hailie Shertzer
Genetic Relationships And Therapeutic Options For Relapsed Acute Lymphoblastic Leukemia, Hailie Shertzer
Senior Honors Theses
Acute lymphoblastic leukemia (ALL) is the most common form of cancer among children and can be lethal to the adult population. Though 80% of patients with ALL reach complete remission after treatment, about 20% of those diagnosed fail to remain cancer-free. Genetic rearrangements are the hallmark of relapsed ALL, but the mechanism by which these rearrangements occur is still unclear. Recent research suggests these mutations may be detectable during initial diagnosis. If researchers are able to accurately assess the probability of relapse during diagnosis by analyzing the genome of the leukemic cells, the likelihood of administering effective therapy would increase. …
Alzheimer's And Amyloid Beta: Amyloidogenicity And Tauopathy Via Dyshomeostatic Interactions Of Amyloid Beta, Jordan Tillinghast
Alzheimer's And Amyloid Beta: Amyloidogenicity And Tauopathy Via Dyshomeostatic Interactions Of Amyloid Beta, Jordan Tillinghast
Senior Honors Theses
This paper reviews functions of Amyloid-β (Aβ) in healthy individuals compared to the consequences of aberrant Aβ in Alzheimer’s disease (AD). As extraneuronal Aβ accumulation and plaque formation are characteristics of AD, it is reasonable to infer a pivotal role for Aβ in AD pathogenesis. Establishing progress of the disease as well as the mechanism of neurodegeneration from AD have proven difficult (Selkoe, 1994). This thesis provides evidence suggesting the pathogenesis of AD is due to dysfunctional neuronal processes involving Aβ’s synaptic malfunction, abnormal interaction with tau, and disruption of neuronal homeostasis. Significant evidence demonstrates that AD symptoms are partially …
Spinal Cord Trauma: An Overview Of Normal Structure And Function, Primary And Secondary Mechanisms Of Injury, And Emerging Treatment Modalities, Daniel Morin
Senior Honors Theses
The structures of the spinal cord and vertebral column are designed to provide flexibility, while still providing ample protection for the spinal cord deep within. While it does offer remarkable protection against most routine trauma, the spinal cord is still vulnerable to high-force etiologies of trauma and may become damaged as a result. These events are referred to as primary injury. Following the initial injury, the body’s own physiological responses cause a cascade of deleterious effects, known as secondary injury. Secondary injury is a major therapeutic target in mitigating the effects of spinal cord injury (SCI), and much research is …
An Examination Into The Relationship Between Iron Deficiency And Postpartum Depression, Sara A. Burroughs
An Examination Into The Relationship Between Iron Deficiency And Postpartum Depression, Sara A. Burroughs
Senior Honors Theses
Postpartum depression is recognized as the most common complication of childbearing; however, its etiology remains fairly undetermined. Many different influences have been hypothesized as to what may cause postpartum depression, including changes in levels of various hormones (such as estrogen and progesterone), a decrease in serotonin, low levels of vitamin D, social factors, and iron deficiency. The lack of strong evidence for one specific cause makes it fairly clear that there are many factors that play a role in the development of postpartum depression. Iron deficiency is one issue that is thought to contribute to the development of postpartum depression …
Gene Expression And Alzheimer's Disease: Evaluation Of Gene Expression Patterns In Brain And Blood For An Alzheimer's Disease Mouse Model, Amanda Hazy
Senior Honors Theses
Previous studies have established a causative role for altered gene expression in development of Alzheimer’s disease (AD). These changes can be affected by methylation and miRNA regulation. In this study, expression of miRNA known to change methylation status in AD was assessed by qPCR. Genome-wide expression changes were determined by RNA-sequencing of mRNA from hippocampus and blood of control and AD mice. The qPCR data showed significantly increased expression of Mir 17 in AD, and sequencing data revealed 230 genes in hippocampus, 58 genes in blood, and 8 overlapping genes showing significant differential expression (p value ≤ 0.05). Expression data …
The Pluripotency Proposition: A Biological And Ethical Case For The Utilization Of Hipscs In Place Of Hescs, Drew Dickson
The Pluripotency Proposition: A Biological And Ethical Case For The Utilization Of Hipscs In Place Of Hescs, Drew Dickson
Senior Honors Theses
Human embryonic stem cell (hESC) research has spurred ethical controversy ever since it became feasible in 1998. The reason for this is due to the fact that hESC research requires the destruction of a human embryo, thereby causing the cessation of life for that developing human. Despite this unavoidable consequence, many advocates of hESC research hold to the belief that the embryo is not actually a human person, and therefore deem the destruction of the embryo as justifiable. Many advocates of hESC research also have pointed to the unprecedented medical potential of hESCs to argue in favor of their case. …
