Bronchopulmonary Dysplasia: Pathophysiology And The Effects Of The Microbiome, Anjali Jacob May 2024

Bronchopulmonary Dysplasia: Pathophysiology And The Effects Of The Microbiome, Anjali Jacob

Senior Honors Theses

Bronchopulmonary dysplasia (BPD) is a chronic neonatal lung disease that occurs in over 50% of premature infants. BPD is characterized by damage to the alveoli and bronchioles and improper vasculature formation. It is primarily caused by overexposure to oxygen through mechanical ventilation, but there are other risk factors that make infants more susceptible to BPD. Microbial composition impacts risk for developing BPD, and research is ongoing about the effects of the microbiome on BPD pathogenesis; this information is also valuable for preventative treatment. This paper reviews the normal function of the lungs, pathogenesis of BPD and how it affects normal …


The Molecular Basis Of Maple Syrup Urine Disease, Chloe Jensen May 2024

The Molecular Basis Of Maple Syrup Urine Disease, Chloe Jensen

Senior Honors Theses

Maple syrup urine disease (MSUD) is a rare metabolic disorder that is caused by mutations in the branched chain alpha keto acid dehydrogenase enzyme complex (BCKDC). There are three main genes, the BCKDHA, BCKDHB, and DBT, that affect the BCKDC, all contributing to the onset of the disease. MSUD causes encephalopathy, neural deficits, maple syrup scented urine, coma, and even death if not treated due to the aggregation of branched-chain amino acids (BCAAs). There is currently no known cure for patients with MSUD, but the condition can be managed to improve quality of life. This review serves to examine MSUD …

Digital Clock Drawing As An Alzheimer's Disease Susceptibility Biomarker: Associations With Genetic Risk Score And Apoe In Older Adults, L I Thompson, M Cummings, S Emrani, David J. Libon, A Ang, C Karjadi, R Au, C Liu

Rowan-Virtua School of Osteopathic Medicine Faculty Scholarship

BACKGROUND: Alzheimer's disease (AD) is the leading cause of dementia in older adults, but most people are not diagnosed until significant neuronal loss has likely occurred along with a decline in cognition. Non-invasive and cost-effective digital biomarkers for AD have the potential to improve early detection.

OBJECTIVE: We examined the validity of DCTclockTM (a digitized clock drawing task) as an AD susceptibility biomarker.

DESIGN: We used two primary independent variables, Apolipoprotein E (APOE) ε4 allele carrier status and polygenic risk score (PRS). We examined APOE and PRS associations with DCTclockTM composite scores as dependent measures.

SETTING: We used existing data …

AMONDYS 45 (casimersen) is an antisense oligonucleotide therapy used to treat Duchenne muscular dystrophy (DMD), a rare genetic disorder characterized by a mutation in the DMD gene. Symptoms include progressive muscle weakness, respiratory and cardiac complications, and premature death. Casimersen targets a specific mutation in the DMD gene that results in the absence of dystrophin protein, a key structural component of muscle fibers. While there is currently no cure for DMD, exon-skipping therapy works by restoring the reading frame of the mutated gene, allowing the production of a partially functional dystrophin protein. Clinical trials of casimersen have shown promising results …

Department of Biochemistry and Molecular Biology Faculty Papers

Spinal and bulbar muscular atrophy (SBMA) is an X-linked disorder that affects males who inherit the androgen receptor (AR) gene with an abnormal CAG triplet repeat expansion. The resulting protein contains an elongated polyglutamine (polyQ) tract and causes motor neuron degeneration in an androgen-dependent manner. The precise molecular sequelae of SBMA are unclear. To assist with its investigation and the identification of therapeutic options, we report here a new model of SBMA in Drosophila melanogaster. We generated transgenic flies that express the full-length, human AR with a wild-type or pathogenic polyQ repeat. Each transgene is inserted into the same safe …

In 2022, a surge in cases of pediatric human parechovirus (HPeV) central nervous system infections in young infants was seen at our institution. Despite the dramatic increase in the number of cases seen that year, the clinical features of the illness were similar to prior years. The recent pediatric HPeV surge highlights the need to evaluate treatment options and standardize follow-up to better understand the long-term prognosis of infants with HPeV infection.

Repurposing Normal Chromosomal Microarray Data To Harbor Genetic Insights Into Congenital Heart Disease, Nephi Walton, Hoang Nguyen, Sara Procknow, Darren Johnson, Alexander Anzelmi, Patrick Jay

Department of Medicine Faculty Papers

About 15% of congenital heart disease (CHD) patients have a known pathogenic copy number variant. The majority of their chromosomal microarray (CMA) tests are deemed normal. Diagnostic interpretation typically ignores microdeletions smaller than 100 kb. We hypothesized that unreported microdeletions are enriched for CHD genes. We analyzed "normal" CMAs of 1762 patients who were evaluated at a pediatric referral center, of which 319 (18%) had CHD. Using CMAs from monozygotic twins or replicates from the same individual, we established a size threshold based on probe count for the reproducible detection of small microdeletions. Genes in the microdeletions were sequentially filtered …

ABSTRACT: Hemophilia B (HB) is caused by an inherited deficiency of plasma coagulation factor IX (FIX). Approximately 60% of pediatric patients with HB possess a severe form of FIX deficiency (< 1% FIX activity). Treatment typically requires replacement therapy through the administration of FIX. However, exogenous FIX has a limited functional half-life, and the natural anticoagulant protein S (PS) inhibits activated FIX (FIXa). PS ultimately limits thrombin formation, which limits plasma coagulation. This regulation of FIXa activity by PS led us to test whether inhibiting PS would extend the functional half-life of FIX and thereby prolong FIX-based HB therapy. We assayed clotting times and thrombin generation to measure the efficacy of a PS antibody for increasing FIX activity in commercially obtained plasma and plasma from pediatric patients with HB. We included 11 pediatric patients who lacked additional comorbidities and coagulopathies. In vivo, we assessed thrombus formation in HB mice in the presence of the FIXa ± PS antibody. We found an accelerated rate of clotting in the presence of PS antibody. Similarly, the peak thrombin formed was significantly greater in the presence of the PS antibody, even in plasma from patients with severe HB. Furthermore, HB mice injected with PS antibody and FIX had a 4.5-fold higher accumulation of fibrin at the thrombus induction site compared with mice injected with FIX alone. Our findings imply that a PS antibody would be a valuable adjunct to increase the effectiveness of FIX replacement therapy in pediatric patients who have mild, moderate, and severe HB.


A Cryptic Microdeletion Del(12)(P11.21p11.23) Within An Unbalanced Translocation T(7;12)(Q21.13;Q23.1) Implicates New Candidate Loci For Intellectual Disability And Kallmann Syndrome, Afif Ben-Mahmoud, Shotaro Kishikawa, Vijay Gupta, Natalia T.

In a patient diagnosed with both Kallmann syndrome (KS) and intellectual disability (ID), who carried an apparently balanced translocation t(7;12)(q22;q24)dn, array comparative genomic hybridization (aCGH) disclosed a cryptic heterozygous 4.7 Mb deletion del(12)(p11.21p11.23), unrelated to the translocation breakpoint. This novel discovery prompted us to consider the possibility that the combination of KS and neurological disorder in this patient could be attributed to gene(s) within this specific deletion at 12p11.21-12p11.23, rather than disrupted or dysregulated genes at the translocation breakpoints. To further support this hypothesis, we expanded our study by screening five candidate genes at both breakpoints of the chromosomal translocation …

Physical activity of a sufficient amount and intensity is essential to health and the prevention of a sedentary lifestyle in all children as they transition into adolescence and adulthood. While fostering a fit lifestyle in all children can be challenging, it may be even more so for those with cerebral palsy (CP). Evidence suggests that bone and muscle health can improve with targeted exercise programs for children with CP. Yet, it is not clear how musculoskeletal improvements are sustained into adulthood. In this perspective, we introduce key ingredients and guidelines to promote bone and muscle health in ambulatory children with …

Proximal spinal muscular atrophy (SMA) is a leading genetic cause for infant death in the world and results from the selective loss of motor neurons in the spinal cord. SMA is a consequence of low levels of SMN protein and small molecules that can increase SMN expression are of considerable interest as potential therapeutics. Previous studies have shown that both 4-phenylbutyrate (4PBA) and trichostatin A (TSA) increase SMN expression in dermal fibroblasts derived from SMA patients. AR42 is a 4PBA-tethered TSA derivative that is a very potent histone deacetylase inhibitor. SMA patient fibroblasts were treated with either AR42, AR19 (a …

Physical activity of at least moderate intensity in all children contributes to higher levels of physical and psychological health. While essential, children with cerebral palsy (CP) often lack the physical capacity, resources, and knowledge to engage in physical activity at a sufficient intensity to optimize health and well-being. Low levels of physical activity place them at risk for declining fitness and health, contributing to a sedentary lifestyle. From this perspective, we describe a framework to foster a lifelong trajectory of fitness in ambulatory children with CP (GMFCS I–III) as they progress into adolescence and adulthood, implemented in conjunction with a …

Genome Editing For Cystic Fibrosis, Guoshun Wang

School of Medicine Faculty Publications

Cystic fibrosis (CF) is a monogenic recessive genetic disorder caused by mutations in the CF Transmembrane-conductance Regulator gene (CFTR). Remarkable progress in basic research has led to the discovery of highly effective CFTR modulators. Now ~90% of CF patients are treatable. However, these modulator therapies are not curative and do not cover the full spectrum of CFTR mutations. Thus, there is a continued need to develop a complete and durable therapy that can treat all CF patients once and for all. As CF is a genetic disease, the ultimate therapy would be in-situ repair of the genetic lesions in the …

Kearns-Sayre syndrome (KSS) is a mitochondrial encephalopathic disorder. Because mitochondria are ubiquitous organelles that are present in almost every human tissue, their dysfunction can affect nearly any organ system and give rise to a wide range of clinical characteristics. 1: As is the case with most diseases associated with mitochondrial DNA (mtDNA) mutations, the clinical features of KSS were defined before modern molecular genetic classifications emerged. 2: The exact prevalence of KSS is unknown; however, estimates place it at about 1:100,000 people. Although it is a rather rare syndrome, the ability to recognize or consider KSS as part of a …

Hereditary angioedema (HAE) is an autosomal dominant disorder caused by a mutation in the C1 esterase inhibitor gene. HAE affects 1/50,000 people worldwide. Three main types of HAE exist: type I, type II, and type III. Type I is characterized by a deficiency in C1-INH. C1-INH is important in the coagulation complement, contact systems, and fibrinolysis. Most HAE cases are type I. Type I and II HAE result from a mutation in the SERPING1 gene, which encodes C1-INH. Formally known as type III HAE is typically an estrogen-dependent or hereditary angioedema with normal C1-INH activity. Current guidelines now recommend subdividing …

Children born with spina bifida, a neural tube defect, can have associated loss of bowel control resulting in bowel incontinence. The National Patient Spina Bifida Registry found that 87% of those living with spina bifida had bowel incontinence, and less than 30% were bowel continent (Sawin et al., 2015; Wiener et al., 2017). Unfortunately, providers may never start a child living with spina bifida on a bowel management program. Evidence suggests that children with spina bifida should begin a bowel management program early, using a stepwise approach. School nurses, who interact with children living with spinal bifida while attending school, …

While we often perceive disease as negative, there is potential to engineer seemingly negative biological phenomena into therapeutics to treat a variety of human illnesses. Fibrodysplasia ossificans progressiva (FOP) is a genetic disorder involving uncontrolled, widespread, extraskeletal bone growth, or heterotopic ossification (HO). In FOP patients, stem cells called fibro/adipogenic progenitors (FAPs) follow an abnormal, osteogenic pathway. In the present study, we investigate whether we can adapt these Acvr1 mutant FAPs, which are exceptional at producing bone, to repair bone fractures in otherwise normal patients. The primary aims of this study are (1) to devise and optimize a novel method …

Introduction: Packed cell transfusion is a lifesaving procedure in premature babies as they have more complications as compared to babies who are born at term. Complications related to prematurity increase as gestational age decreases and anemia is one of the complications of prematurity which needs packed cell transfusions. To date, when to transfuse preterm babies and what would be the threshold for hemoglobin and hematocrit is still a point of argument as well as liberal versus restrictive transfusion protocols have been developed but what should be followed still needs more data. In our study, we have observed frequencies of different …

Low birthweight due to intrauterine growth restriction is associated with metabolic disorders after birth. Our 1st study assessed deficits in skeletal muscle glucose metabolism and pancreatic β cell function in IUGR fetal sheep. We aimed to evaluate the effectiveness of daily intravenous infusions of the anti-inflammatory ω-3 polyunsaturated fatty acid (PUFA), eicosapentaenoic acid (EPA), as a means of improving deficits previously observed in the IUGR fetus by targeting fetal systemic inflammation. The presence of systemic inflammation in IUGR fetuses was evident by increased total circulating populations of total leukocytes, lymphocytes, and monocytes. However, these were …
