Mechanisms Of Smoothened Regulation In Hedgehog Signaling, Jie Zhang, Zulong Liu, Jianhang Jia

Markey Cancer Center Faculty Publications

The seven-transmembrane protein, Smoothened (SMO), has shown to be critical for the hedgehog (HH) signal transduction on the cell membrane (and the cilium in vertebrates). SMO is subjected to multiple types of post-translational regulations, including phosphorylation, ubiquitination, and sumoylation, which alter SMO intracellular trafficking and cell surface accumulation. Recently, SMO is also shown to be regulated by small molecules, such as oxysterol, cholesterol, and phospholipid. The activity of SMO must be very well balanced by these different mechanisms in vivo because the malfunction of SMO will not only cause developmental defects in early stages, but also induce cancers in late …

Dermatitis Herpetiformis: An Update On Diagnosis, Disease Monitoring, And Management, Christopher N Nguyen, Soo-Jung Kim

Faculty, Staff and Students Publications

Dermatitis herpetiformis (DH), Duhring disease, is caused by gluten sensitivity and affects 11.2 to 75.3 per 100,000 people in the United States and Europe with an incidence of 0.4 to 3.5 per 100,000 people per year. DH is characterized by a symmetrical blistering rash on the extensor surfaces with severe pruritus. The diagnosis continues to be made primarily by pathognomonic findings on histopathology, especially direct immunofluorescence (DIF). Recently, anti-epidermal transglutaminase (TG3) antibodies have shown to be a primary diagnostic serology, while anti-tissue transglutaminase (TG2) and other autoantibodies may be used to support the diagnosis and for disease monitoring. Newly diagnosed …

Moving Beyond Size: Vorticity And Energy Loss Are Correlated With Right Ventricular Dysfunction And Exercise Intolerance In Repaired Tetralogy Of Fallot., Yue-Hin Loke, Francesco Capuano, Vincent Cleveland, Jason G. Mandell, Elias Balaras, Laura J. Olivieri

Pediatrics Faculty Publications

BACKGROUND: The global effect of chronic pulmonary regurgitation (PR) on right ventricular (RV) dilation and dysfunction in repaired Tetralogy of Fallot (rTOF) patients is well studied by cardiovascular magnetic resonance (CMR). However, the links between PR in the RV outflow tract (RVOT), RV dysfunction and exercise intolerance are not clarified by conventional measurements. Not all patients with RV dilation share the same intracardiac flow characteristics, now measurable by time resolved three-dimensional phase contrast imaging (4D flow). In our study, we quantified regional vorticity and energy loss in rTOF patients and correlated these parameters with RV dysfunction and exercise capacity.

METHODS: …

Arisi, Lorenzo Gerratana, Jennifer S Winn, Michael Slifker, Jianming Pei, Kathy Q Cai, Zachary Hasse, Elias Obeid, Julio Noriega, Christopher Sebastiano, Eric Ross, Katherine Alpaugh, Massimo Cristofanilli, Sandra V Fernandez

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

To better understand the etiology of inflammatory breast cancer (IBC) and identify potential therapies, we studied genomic alterations in IBC patients. Targeted, next-generation sequencing (NGS) was performed on cell-free DNA (cfDNA) (n = 33) and paired DNA from tumor tissues (n = 29) from 32 IBC patients. We confirmed complementarity between cfDNA and tumor tissue genetic profiles. We found a high incidence of germline variants in IBC patients that could be associated with an increased risk of developing the disease. Furthermore, 31% of IBC patients showed deficiencies in the homologous recombination repair (HRR) pathway (BRCA1, BRCA2, PALB2, RAD51C, ATM, BARD1) …

Center for Environmental and Systems Biochemistry Faculty Publications

Although Pembrolizumab-based immunotherapy has significantly improved lung cancer patient survival, many patients show variable efficacy and resistance development. A better understanding of the drug’s action is needed to improve patient outcomes. Functional heterogeneity of the tumor microenvironment (TME) is crucial to modulating drug resistance; understanding of individual patients’ TME that impacts drug response is hampered by lack of appropriate models. Lung organotypic tissue slice cultures (OTC) with patients’ native TME procured from primary and brain-metastasized (BM) non-small cell lung cancer (NSCLC) patients were treated with Pembrolizumab and/or beta-glucan (WGP, an innate immune activator). Metabolic tracing with ¹³C₆-Glc/ …

Gross Hematuria: An Unusual Presenting Symptom Of Systemic Wild-Type Transthyretinamyloidosis., Sage A. Vincent, Daniel Christensen, Perry R. Weiner

Department of Urology Faculty Papers

Amyloidosis of the urinary bladder is a rare cause of gross hematuria. In patients with systemic amyloidosis, identification is nearly always related to cardiac complaints; urologic presenting symptoms are extremely uncommon. We present a 77-year-old male patient with painless gross hematuria ultimately found to be secondary to systemic wild-type transthyretin amyloidosis. He underwent transurethral resection of the bladder lesion and was initiated on transthyretin stabilizing medication. In the 6 months since starting treatment, the patient has had no further episodes of gross hematuria, but will require cystoscopic surveillance for evidence of recurrence or concomittment urothelial carcinoma.

Advances In The Diagnosis And Treatment Of Krabbe Disease, David A Wenger, Paola Luzi, Mohammad Rafi

Department of Neurology Faculty Papers

Krabbe disease is an autosomal recessive leukodystrophy caused by pathogenic variants in the galactocerebrosidase (GALC) gene. GALC activity is needed for the lysosomal hydrolysis of galactosylceramide, an important component of myelin. While most patients are infants, older patients are also diagnosed. Starting in 1970, a diagnosis could be made by measuring GALC activity in leukocytes and cultured cells. After the purification of GALC in 1993, the cDNA and genes were cloned. Over 260 disease-causing variants as well as activity lowering benign variants have been identified. While some pathogenic variants can be considered “severe,” others can be considered “mild.” The combination …

Correcting For Sparsity And Interdependence In Glycomics By Accounting For Glycan Biosynthesis, Bokan Bao, Benjamin P Kellman, Austin W T Chiang, Yujie Zhang, James T Sorrentino, Austin K York, Mahmoud A Mohammad, Morey W Haymond, Lars Bode, Nathan E Lewis

Children’s Nutrition Research Center Staff Publications

Glycans are fundamental cellular building blocks, involved in many organismal functions. Advances in glycomics are elucidating the essential roles of glycans. Still, it remains challenging to properly analyze large glycomics datasets, since the abundance of each glycan is dependent on many other glycans that share many intermediate biosynthetic steps. Furthermore, the overlap of measured glycans can be low across samples. We address these challenges with GlyCompare, a glycomic data analysis approach that accounts for shared biosynthetic steps for all measured glycans to correct for sparsity and non-independence in glycomics, which enables direct comparison of different glycoprofiles and increases statistical power. …

The Reel Deal: The Stacked Benefits Of A Reel Mower, John K. Hix, Simone Bailey

Advances in Clinical Medical Research and Healthcare Delivery

"Mow-lawning" is a colloquial term referred to actively cutting grass using a reel mower, typically at a faster than normal pace in order to maximize exercise benefit and minimize time, with the emphasis on the physical action of mowing and only secondarily on the resulting lawn care. While mow-lawning remains relatively uncommon in the United States, adoption of this practice by those healthy enough to engage in the level of exercise required can deliver a number of benefits that improve environmental, safety, and personal goals simultaneously. The stacking of so many benefits in one practice deserves more attention and promotion.

Omental Tuberculosis In A Patient With Alcoholic Liver Cirrhosis-The Diagnostic And Treatment Dilemma, Ekta Tirthani, Mina Said

Advances in Clinical Medical Research and Healthcare Delivery

Alcoholic cirrhosis is frequently complicated by spontaneous bacterial peritonitis (SBP) due to the translocation of gut bacteria. However, in immigrants to the USA from parts of the world with high tuberculosis burden, a high degree of clinical suspicion of tuberculous peritonitis should be maintained when a patient presents with symptoms similar to SBP. We describe a case of a 45-year-old Nepali man with a history of alcohol abuse who immigrated to the USA six years prior and presented to the hospital with abdominal pain, night sweats, fevers, and a 10 kg weight loss. A CT scan revealed abdominopelvic ascites, liver …

Preparing Internal Medicine Trainees For Independent Practice: A Pilot Simulation Program On Emotional Intelligence, Deborah Maier, Nagesh Jadhav, Christina Goodermote, Richard Alweis

Advances in Clinical Medical Research and Healthcare Delivery

Introduction: Emotional intelligence (EI) is the ability to monitor emotions and use this knowledge to guide one’s thinking and actions. EI shapes the physician’s bedside manner and leads to a better doctor-patient relationship. Higher physician EI is inversely proportional to feelings of burnout and increases resiliency to the stresses of the profession. Given the increasing levels of physician burnout, there has been a call to incorporate the development of emotional intelligence into medical education. However, little guidance exists on best practices in incorporating EI training into graduate medical education.

Purpose/Aim: Utilization of EI simulation as a pedagogical instrument to increase …

Obstetrics and Gynecology Faculty Publications

The development of patient-derived tumor organoids (TOs) from an epithelial ovarian cancer tumor obtained at the time of primary or interval debulking surgery has the potential to play an important role in precision medicine. Here, we utilized TOs to test front-line chemotherapy sensitivity and to investigate genomic drivers of carboplatin resistance. We developed six high-grade, serous epithelial ovarian cancer tumor organoid lines from tissue obtained during debulking surgery (two neoadjuvant-carboplatin-exposed and four chemo-naïve). Each organoid line was screened for sensitivity to carboplatin at four different doses (100, 10, 1, and 0.1 µM). Cell viability curves and resultant EC₅₀ values …

Management Of Fall Patients – What Should Be Done For Emergency Department Fall Patients?, Katherine Selman, Christine Binkley, Katherine Davenport, Shan W. Lliu, Maura Kennedy

Journal of Geriatric Emergency Medicine

Falls are the leading cause of injury-related emergency visits in older adults, translating into an estimated 3 million ED visits and 32,000 deaths from fall-related injuries annually in the United States. Falls subsequently result in diminished functional ability and higher risk for future falls and mortality. Despite this, ED clinicians focus primarily on injuries that result from a fall and often defer the modifiable causes of the fall and future fall prevention to outpatient providers. We review two articles that address the feasibility of performing interventions from the ED and the efficacy of a multifactorial fall intervention program.
