Role Of Atp1a1 In Skeletal Muscle Growth And Metabolism, 2020 Marshall University
Role Of Atp1a1 In Skeletal Muscle Growth And Metabolism, Laura C. Kutz
Theses, Dissertations and Capstones
Skeletal muscle comprises approximately 30% of total body mass, and loss of muscle mass and dysfunctional muscle metabolism are implicated in multiple disease states, including type 2 diabetes, heart failure, and septic shock. As such, understanding the mechanisms of skeletal muscle growth and atrophy, including pharmaceutical targets that may prove safe and effective, is therefore an important goal of current research on skeletal muscle physiology. One potential target in skeletal muscle development and function that has not been fully explored is the Na/KATPase (NKA), especially the α1 isoform. This isoform has a unique signaling function that has previously been ...
Oral Contraceptives As Possible Acl Injury Prevention Method, 2020 Arcadia University
Oral Contraceptives As Possible Acl Injury Prevention Method, Haley Schweizer
Introduction: Anterior Cruciate Ligament (ACL) injuries are an upsetting setback for many athletes that require a long and costly recovery process. The injury rates are four times greater in women than men. Preventative measures that help to prevent ACL injuries are limited to stretching and strengthening. Therefore, this review aims to investigate if oral contraceptive [I] usage provides a possible new avenue for prevention of ACL injury [O] in young female athletes (ages 18-30) [P] compared to those that do not take oral contraceptives [C].
Methods: A literature review was performed though PubMed, Google Scholar, SCOPUS Database, and ClinicalKey ...

Oligogenic Effects Of 16p11.2 Copy-Number Variation On Craniofacial Development, 2019 University of California - San Diego
Oligogenic Effects Of 16p11.2 Copy-Number Variation On Craniofacial Development, Yuqi Qiu, Curtis K. Deutsch, Jonathan Sebat
Open Access Articles
A copy-number variant (CNV) of 16p11.2 encompassing 30 genes is associated with developmental and psychiatric disorders, head size, and body mass. The genetic mechanisms that underlie these associations are not understood. To determine the influence of 16p11.2 genes on development, we investigated the effects of CNV on craniofacial structure in humans and model organisms. We show that deletion and duplication of 16p11.2 have "mirror" effects on specific craniofacial features that are conserved between human and rodent models of the CNV. By testing dosage effects of individual genes on the shape of the mandible in zebrafish, we identify ...

Protein turnover is one of the most essential mechanisms controlling circadian rhythms. F-Box and Leucine Rich Repeat Protein21 (FBXL21) is a circadian E3 ligase which shows oscillatory mRNA transcripts and protein levels. It was previously found to perform subcellular compartment-specific E3 ligase activities targeting the core clock proteins CRYPTOCHROME(CRY)1/2. Here we identified a new sarcomeric target substrate, Telethonin(TCAP), which also shows circadian oscillation in its mRNA transcript and protein expression and, importantly, interaction with FBXL21 in an anti-phasic manner. Via computational and pharmacological tests, we identified Glycogen Synthase Kinase-3β(GSK-3β) as a regulator of FBXL21. Biochemical ...

Differential Role Of Pontomedullary Glutamatergic Neuronal Populations In Sleep-Wake Control, Evelyn T. M. Erickson, Loris L. Ferrari, Heinrich S. Gompf, Christelle Anaclet
Parafacial zone (PZ) GABAergic neurons play a major role in slow-wave-sleep (SWS), also called non-rapid eye movement (NREM) sleep. The PZ also contains glutamatergic neurons expressing the vesicular transporter for glutamate, isoform 2 (Vglut2). We hypothesized that PZ Vglut2-expressing (PZ(Vglut2)) neurons are also involved in sleep control, playing a synergistic role with PZ GABAergic neurons. To test this hypothesis, we specifically activated PZ(Vglut2) neurons using the excitatory chemogenetic receptor hM3Dq. Anatomical inspection of the injection sites revealed hM3Dq transfection in PZ, parabrachial nucleus (PB), sublaterodorsal nucleus (SLD) or various combinations of these three brain areas. Consistent with the ...

Low Birth Weight And Post-Natal Diet Induced Alterations In Skeletal Muscle Oxygen Consumption And Fiber Type Composition, Megan Cedrone
Electronic Thesis and Dissertation Repository
Adverse in utero and postnatal conditions can increase susceptibility to metabolic syndrome (MS). Altered muscle respiration contributes to MS, but the effects of restricted oxygen and nutrients in utero on skeletal muscle mitochondria remain unknown. In this study guinea pig sows underwent uterine artery ablations mid-gestation, producing fetuses with low birth weight (LBW). Soleus muscle was collected near term or at four months of age, from LBW and control fetuses and offspring, where the offspring were fed either a Western Diet (WD) or a control diet (CD). Soleus muscles from LBW fetuses exhibit lower maximal respiration rates than normal birth ...
Altering Entry Angles In A Jump Landing Task Modifies Biomechanical Risk Factors Of Acl Injury, 2019 Iowa State University
Altering Entry Angles In A Jump Landing Task Modifies Biomechanical Risk Factors Of Acl Injury, Shekoofe Saadat, Mitchell L. Stephenson, Jason C. Gillette
Kinesiology Presentations, Posters and Proceedings
This study investigated the effects of changing the entry-angle of a jump landing movement on ACL injury risk factors. Eight female recreational athletes performed 21 trials of a jump landing task. The direction of the first jump varied from -90° to 90° from the anterior axis in 30-degree increments. As the entry angle increased to the left, peak knee flexion and valgus angles as well as external valgus moments remained the same. In conditions where participants jumped more to their right, knee flexion angles were smaller and knee external valgus moments were greater. It can be concluded that kinematic analyses ...
Efficacy Of Shoes And Boots In Preventing Motorcycle-Related Ankle Inversion., 2019 Des Moines University
Efficacy Of Shoes And Boots In Preventing Motorcycle-Related Ankle Inversion., Justin T. Wilder, Mitchell L. Stephenson, Jason C. Gillette
Kinesiology Presentations, Posters and Proceedings
The current investigation explored the potential prophylactic effects of shoes, work boots, and motorcycle boots in reducing ankle inversion associated with ankle sprain. While the majority of previous research has investigated the effects of protective equipment in crashes, rates of lower extremity loading in emergency stop contexts are comparable to jump landings and may induce frontal plane loading that could lead to ankle injury. Fifteen adults wore athletic shoes, work boots, and motorcycle boots in a motorcycle drop task. Motorcycle boots significantly (p = 0.03) decreased peak ankle inversion angles by 3.6 degrees, but also increased (p < 0.01) vertical ground reaction forces by 0.21 bodyweights compared to the other shod conditions. Overall, it is suggested that motorcycle boots can potentially protect motorcycle riders from both crash-based and emergency-stop injuries.

Calcineurin (Cn) is a calcium-activated serine/threonine protein phosphatase that is broadly implicated in diverse cellular processes, including the regulation of gene expression. During skeletal muscle differentiation, Cn activates the NFAT transcription factor but also promotes differentiation by counteracting the negative influences of protein kinase C beta (PKCbeta) via dephosphorylation and activation of BRG1, an enzymatic subunit of the mammalian SWI/SNF ATP-dependent chromatin remodeling enzyme. Here we identified four major temporal patterns of Cn-dependent gene expression in differentiating myoblasts and determined that Cn is broadly required for the activation of the myogenic gene expression program. Mechanistically, Cn promotes gene ...
Modulation Of Inflammation Driven Wound Healing After Glaucoma Surgery, 2019 The University of Western Ontario
Modulation Of Inflammation Driven Wound Healing After Glaucoma Surgery, James J. Armstrong
Electronic Thesis and Dissertation Repository
Dysregulated wound healing contributes to most currently unanswered ophthalmological morbidity. Opacification and structure altering contractures compromise the delicate ocular anatomy upon which ocular function and healthy vision are reliant. Glaucoma filtration surgery, corneal stromal injury, proliferative vitreoretinopathy and age-related macular degeneration are major contributors to ocular morbidity – all with myofibroblast transdifferentiation and pathognomonic scarring activity at their core.
This thesis aims to revaluate the means by which dysregulated ocular wound healing is combated with evidence describing a novel strategy to mitigate its effects. A translational approach was used. An initial retrospective analysis of over ten thousand glaucoma surgeries found that ...

Osteoporosis is associated with an increased risk of pathologic fractures; however, most patients do not receive diagnosis and adequate treatment. The aim of our study was to compare the yearly trends of osteoporosis and osteoporotic fragility fractures in the USA (US) inpatients. We used National (Nationwide) Inpatient Sample database to identify adults ≥18 years with diagnoses of osteoporosis and pathologic fractures and excluded pathologic fractures due to other etiologies. We then studied the annual trends, in terms of annual percentage change (APC), of osteoporosis and osteoporotic fractures. Among overall hospitalizations, osteoporosis was noted to have an increasing trend from 2000 ...

MTF1 is a conserved metal-binding transcription factor in eukaryotes that binds to conserved DNA sequence motifs, termed metal response elements (MREs). MTF1 responds to metal excess and deprivation, protects cells from oxidative and hypoxic stresses, and is required for embryonic development in vertebrates. We used multiple strategies to identify an unappreciated role for MTF1 and copper (Cu) in cell differentiation. Upon initiation of myogenesis from primary myoblasts, MTF1 expression increased, as did nuclear localization. Mtf1 knockdown impaired differentiation, while addition of non-toxic concentrations of Cu+ enhanced MTF1 expression and promoted myogenesis. Cu+ bound stoichiometrically to a C-terminus tetra-cysteine of MTF1 ...
