The Snakeskin-Mesh Complex Of Smooth Septate Junction Restricts Yorkie To Regulate Intestinal Homeostasis In Drosophila, Hsi-Ju Chen, Qi Li, Niraj K. Nirala, Y. Tony Ip

Open Access Articles

Tight junctions in mammals and septate junctions in insects are essential for epithelial integrity. We show here that, in the Drosophila intestine, smooth septate junction proteins provide barrier and signaling functions. During an RNAi screen for genes that regulate adult midgut tissue growth, we found that loss of two smooth septate junction components, Snakeskin and Mesh, caused a hyperproliferation phenotype. By examining epitope-tagged endogenous Snakeskin and Mesh, we demonstrate that the two proteins are present in the cytoplasm of differentiating enteroblasts and in cytoplasm and septate junctions of mature enterocytes. In both enteroblasts and enterocytes, loss of Snakeskin and Mesh ...

Assessment Of Antebrachial And Carpal Muscle Activity During Smartphone Use: Is “Selfie Wrist” A Real Phenomenon?, Monica Stacy

Honors Theses

Reports in the media by celebrities have sparked an interest in a phenomenon being called “selfie-wrist,” in which smartphone users develop symptoms traditionally associated with carpal tunnel syndrome (CTS). There has been no research to date which investigates the claims of “selfie wrist.” The primary aim of this study was to address the validity of “selfie wrist” claims. The secondary aim of this study was to further investigate the effects of texting on musculoskeletal health, taking into account the differences between texting one-handed versus two-handed, and the effect of using a grip device while texting.

The experiment consisted of an ...


The Effects Of Acute Exercise And Psychological Stress On Episodic Memory, Lauren Koehler 2020 University of Mississippi

The Effects Of Acute Exercise And Psychological Stress On Episodic Memory, Lauren Koehler

Honors Theses

Research has suggested that exercise has an effect on memory function. Studies have also shown that exercise mitigates the effects of stress. The relationship between exercise and stress in regard to memory function is noteworthy. There has been little research on this relationship in young adults. This thesis discusses the effects of acute exercise on the episodic memory of young adults when they are exposed to a psychosocial stressor. The results of the research study show that acute aerobic exercise before memory encoding or consolidation was not associated with memory function after exposure to a stressor. Future research in this ...


The Current Neuroscientific Understanding Of Alzheimer's Disease, Rachel A. Brandes 2020 University of Tennessee, Knoxville

The Current Neuroscientific Understanding Of Alzheimer's Disease, Rachel A. Brandes

Pursuit - The Journal of Undergraduate Research at the University of Tennessee

Alzheimer’s disease is a degenerative neurological illness characterized by the deterioration of brain regions implicated in memory and cognitive function. While researchers have yet to find a cure or effective treatment, they have gained a better understanding of its pathology and development. Through years of neuroscience research, scientists have discovered much of what happens in the brain during Alzheimer’s disease onset and how this causes its symptoms; many hypotheses regarding this aspect of the illness involve temporal lobe atrophy, neurofibrillary tangles, and amyloid plaques. Although Alzheimer’s disease affects millions of people every day, it seems that most ...

Examining Permeability And Contractility Of Skeletal Muscle In Castrated Male Mice, Evan Scott 2020 Ursinus College

Examining Permeability And Contractility Of Skeletal Muscle In Castrated Male Mice, Evan Scott

Health and Exercise Physiology Honors Papers

A common method of treating skeletal muscle injury is temperature therapy. Temperature affects one of the initial aspects of skeletal muscle healing, the increasing of vascular permeability. Previous data accumulated from the Ursinus College Skeletal Muscle Lab suggests that vascular permeability following temperature therapy is different between the anatomically intact male and female mice. However, there have not been any studies to date that are able determine the cause of these permeability differences following temperature treatment. In addition, it is currently unclear how increased vascular permeability affects skeletal muscle healing. A possible cause for these differences is the increased presence ...

Costas T. Lambrew Research Retreat 2020

Multiple myeloma (MM) is the third most common blood cancer and is defined by the clonal expansion of malignant plasma cells in the bone marrow (BM). MM remains incurable due to the development of resistance to current chemotherapies; therefore, it is paramount to investigate novel treatments and the mechanisms of drug resistance in multiple myeloma cells. Recently, changes in both catabolic and anabolic lipid metabolism have been shown to support the proliferation, migration and the development of drug resistance in breast, prostate, and ovarian cancer. However, the role of lipid metabolism in myeloma cells has been understudied. Given the data ...

• Multiple myeloma (MM) is an incurable cancer of plasma cells. Myeloma cells grow primarily in the bone marrow (BM) and home throughout the body to extramedullary locations. MM causes aberrant IgG production, renal failure, hypercalcemia, anemia, and bone destruction. MM patients almost always relapse with the disease; finding new ways to target drug resistant MM clones is a major clinical need.

• Bone Marrow Adipocytes (BMAs) have been shown to be supportive of MM cells and are associated with the transitions of both MGUS to MM and remission to relapse, with a strong correlation between high BMI and poor treatment response ...

Atherosclerosis is an inflammatory disease characterized by arterial wall thickening and plaque accumulation, and is a major cause of death worldwide. Vascular smooth muscle cells (VSMC), which have the unique ability to transition from mature contractile cells to myofibroblasts and macrophagelike foam cells, and adopt a proinflammatory state contribute to atherogenic microenvironment (1). We aimed to investigate how Spry1, a regulator of receptor tyrosine kinase signaling, affects hypercholesterolemia induced plaque formation in mice by manipulating Spry1 expression specifically in VSMC.

Lean Phenotype Induced By Methionine Restriction In Mice Is Associated With Proteomic Changes In Perivascular Adipose Tissue, Bethany H. Fortier, Calvin Ph Vary, Robert A. Koza, Gene P. Ables, Lucy Liaw

Costas T. Lambrew Research Retreat 2020

Perivascular adipose tissue (PVAT) surrounds blood vessels, is thermogenic, and secretes adipokines that can be vasoprotective. During aging and obesity, PVAT loses its thermogenic capacity, shows increased inflammation, and secretes proatherogenic cytokines. Our collaborative research has previously shown that dietary methionine restriction (MetR) in mice can decrease adiposity, improve glucose sensitivity, and induce PVAT to become more thermogenic. To identify initiating signals from PVAT that correspond to thermogenic conversion, we challenged male C57BL/6 mice with a high fat diet (HFD, 60 kcal% fat, 0.86% methionine) until they weighed >45g (~12 weeks of age). Weight matched mice were then ...

Sclerostin Antibody Normalizes Decreased Trabecular Bone And Increased Bone Marrow Adipose Tissue Caused By Whole-Body Irradiation In Mice, Samantha Costa, Heather Fairfield, Mariah Farrell, Connor Murphy, Ashley Soucy, Gill Holdsworth, Michaela R. Reagan

Costas T. Lambrew Research Retreat 2020

Irradiation therapy continues to be an accepted medical treatment for many cancers, yet patients are at increased risk for bone deterioration and other skeletal-related events. Irradiation (IR) negatively affects trabecular architecture through increased osteoclast activity and decreased osteoblast activity. Additionally, IR induces increased bone marrow (BM) adipocyte expansion, which may compound IR-induced bone disease. Antibodies to sclerostin (Scl-Ab) increase bone mass and strength by increasing bone formation and reducing bone resorption. We hypothesized Scl-Ab treatment would reverse the adverse effects of IR by increasing bone volume and decreasing BM adipose tissue (BMAT), resulting in improved bone quality. In this study ...

Beyond The Brain: ?-Synuclein And Its Implications In Bone And Fat Metabolism, C A. Figueroa, P Bajgain, C J. Rosen

Costas T. Lambrew Research Retreat 2020

Introduction: Pathological form of α-synuclein is the major component of the Lewy body in the brain of Parkinson’s disease (PD) patients. Research efforts have been directed towards understanding the root and progression of the neurodegeneration and its association to symptoms. Physiological α-synuclein is ubiquitously present in the human body, however, its role outside the central nervous system has been poorly studied. PD seriously impairs life quality; symptoms comprehend from locomotor dysfunction including resting tremors, rigidity and bradykinesia to non-motor features such as autonomic dysfunction, cognitive/neurobehavioral abnormalities, sleep and sensory disorders. Additionally, PD patients often experiment weight loss, impaired ...

Notch Signaling Regulates Perivascular Adipose Tissue (Pvat) Function During Diet-Induced Obesity, Chenhao Yang, Joshua M. Boucher, Larisa M. Ryzhova, Lucy Liaw

Costas T. Lambrew Research Retreat 2020

Background: Obesity is an established risk factor for cardiovascular diseases (CVD) and possibly shares molecular and cellular disease mechanisms as CVD due to their comorbidity. As a component of vasculature, perivascular adipose tissue (PVAT) has been recognized as a critical regulator of vascular function due to its anatomical proximity to the vascular wall. Study in PVAT thus help us understand cross talks between adipose tissue and cardiovascular system to re-evaluate clinical strategies for prevention and treatment of type 2 diabetes and CVD. Recent studies have shown that in addition to development, Notch/Rbp-jk signaling plays a crucial role in regulating ...

Tranexamic Acid Preferentially Localizes In The Nuclei Of Endothelial Cells And Binds Proteins Involved In Gene Expression And Mitochondrial Metabolism, Igor Prudovsky, Doreen Kacer, Victoria Zucco, Keiran Wynne, Damien Carter, Monica Palmeri, Calvin Vary, Robert Kramer, Joseph Rappold

Costas T. Lambrew Research Retreat 2020

Purpose Tranexamic acid (TXA), an anti-fibrinolytic inhibitor of plasmin, is widely used in hemorrhagic trauma patients. We have previously demonstrated that the effects of TXA transcend its inhibition of fibrinolysis by suppressing the release of damage associated molecular patterns (DAMPS), specifically mitochondrial DNA, and decreasing inflammation in a mouse burn model . Additionally, we have demonstrated that TXA increases mitochondrial respiration in human endothelial cells in vitro. Collectively, these results prompted us to hypothesize that TXA has other biologically important molecular targets besides plasmin. Herein we present the initial results of our studies addressing this hypothesis.

Methods To assess the intracellular ...

Role Of Zfp467in Mediating The Anti-Adipogenic And Pro-Osteogenic Effects Of Pth: An In-Vitroanalysis, H Liu, I Leon Calle, P T. Le, R Baron, C J. Rosen

Costas T. Lambrew Research Retreat 2020

Parathyroid hormone (PTH) analogs are the main anabolic pharmacological agent for osteoporosis. PTH is an endogenous hormone. Its amino acids 1-34 bind the parathyroid hormone receptor (PTH1r), a G-coupled protein receptor expressed in kidney, fat, and bone. PTH increases trabecular bone mass by promoting the differentiation of the mesenchymal stem cell (MSC) into the osteogenic lineage. The Zinc Finger Protein 467 (Zfp467) is a potential downstream target of PTH1r and an important mediator of the MSC into the adipogenic lineage. Taken together, we ask whether Zfp467 knockout cells will show greater osteogenic potential and increased sensitivity to PTH treatment. We ...
