The Mechanism Of Β-N-Methylamino-L-Alanine Inhibition Of Trna Aminoacylation And Its Impact On Misincorporation, Nien-Ching Han, Tammy J. Bullwinkle, Kaeli F. Loeb, Kym F. Faull, Kyle Mohler, Jesse Rinehart, Michael Ibba

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

β-N-methylamino-l-alanine (BMAA) is a nonproteinogenic amino acid that has been associated with neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS) and Alzheimer's disease (AD). BMAA has been found in human protein extracts; however, the mechanism by which it enters the proteome is still unclear. It has been suggested that BMAA is misincorporated at serine codons during protein synthesis, but direct evidence of its cotranslational incorporation is currently lacking. Here, using LC-MS–purified BMAA and several biochemical assays, we sought to determine whether any aminoacyl-tRNA synthetase (aaRS) utilizes BMAA as a substrate for aminoacylation. Despite BMAA's previously predicted misincorporation at serine …

Use Of Prame Immunostaining To Distinguish Melanoma In Situ From Lentigo Senilis, Hailey Olds, Sarah Utz, Darius Mehregan

Medical Student Research Symposium

PRAME (PReferentially expressed Antigen in MElanoma) is an antigen that is expressed by malignant cells in melanoma, as well as other cancers such as breast carcinoma, renal cell carcinoma, and leukemia. PRAME immunohistochemistry has proved effective in identifying malignant melanocytes in melanoma lesions, but it is unclear if it may be used to distinguish melanoma from benign melanocytic conditions, such as lentigo senilis. In particular, melanoma in situ may be confused with lentigo senilis clinically and histologically, thus PRAME immunostaining is potentially useful for differentiating these two lesions. We evaluated 31 samples of lentigo senilis, 26 of melanoma in situ, …

Understanding M6a’S Role In The Myometrium During Gestation, Lindsay Jenkins, Arren Simpson, Jennifer Condon Phd, Jeyasuria Pancharatnam Phd

Medical Student Research Symposium

Epigenetic modifications, such as DNA methylation, mainly affects the function of genes through regulating the transcription or translation processes, without altering the DNA sequences. The regulation of m6A modification is dynamic and reversible and is established by m6A methyltransferases (“writers”), such as methyltransferase-like protein 3 (METTL3). It is removed by m6A demethylases (“erasers”), such as α-ketoglutarate-dependent dioxygenase alkB homolog 5 (ALKBH5). The effects of m6A modification on RNA metabolism depend on the recognition by different m6A -binding proteins (“readers”), including the YT521-B homology (YTH) domain family and the heterogeneous nuclear ribonucleoproteins (HNRNPs). We believe …

Same Day Transportation For Opioid Use Disorder: Impact Of The Crisis Addiction Recovery Transportation (Cart) Program, Katherine Palmer Loveluck, Andrew King

Medical Student Research Symposium

Patients with opioid use disorder (OUD) frequently present to the emergency department (ED). Delays or barriers in referral to recovery programs from the ED may decrease successful linkage to ongoing care. Immediately following discharge is a particularly high-risk time for OUD patients as studies have shown that immediately following a non-fatal overdose there is an increase in death rates1. To attempt to combat this gap in care The Detroit Medical Center (DMC) partnered with a community program, Team Wellness (TW), to offer direct transportation 18 hours per day to the TW facility. This crisis addiction recovery transportation (CART) …

Effect Of Trazodone On Upper Airway Resistance In Chronic Spinal Cord Injury, Geoffrey M. Ginter, Sean Carroll, Abdulghani Sankari, Safwan Badr

Medical Student Research Symposium

Background:

Spinal cord injury (SCI) is a known risk factor for sleep-disordered breathing. While device-based therapies such as CPAP are beneficial in these individuals, adherence to these treatments is often low; consequently, pharmacotherapies for sleep-disordered breathing in patients with SCI are in high demand. Trazodone is an atypical antidepressant with a complex mechanism of action, including alpha adrenergic agonist activity and inhibition of serotonin reuptake. Serotonin (5-HT) is a known modulator of respiratory circuitry, which has been shown to influence the ventilatory drive. Trazodone is commonly prescribed as a sleep aid, but its impact on breathing during sleep is still …

A Case Of Recurrent Breast Cancer Diagnosed From Symptomatic Metastasis To Bladder, Reagan M. Stafford, Andrew J. Weaver, Mary Legenza, Douglas Henson

Marshall Journal of Medicine

Abstract:

Women in the United States have an approximate 1 in 8 chance of developing breast cancer in their lifetime. The main cause of death from breast cancer is from metastatic spread of the disease; with the most frequent sites of spread being to the bone, brain, and lungs. The urinary bladder is a rare site of metastasis that has been rarely reported on in the literature. Here we present a case of recurrent metastatic breast cancer found in the urinary bladder without findings of any other sites of metastasis.

Department of Cancer Biology Faculty Papers

Breast cancer commonly metastasizes to bone, resulting in osteolytic lesions and poor patient quality of life. The bone extracellular matrix (ECM) plays a critical role in cancer cell metastasis by means of the physical and biochemical cues it provides to support cellular crosstalk. Current two-dimensional in-vitro models lack the spatial and biochemical complexities of the native ECM and do not fully recapitulate crosstalk that occurs between the tumor and endogenous stromal cells. Engineered models such as bone-on-a-chip, extramedullary bone, and bioreactors are presently used to model cellular crosstalk and bone-tumor cell interactions, but fall short of providing a bone-biomimetic microenvironment. …

Khan, Nisar Ahmed, Farah Yasmin, Rabail Yaseen, Maira Hassan

Section of Cardiothoracic Surgery

Background: Abdominal trauma and intra-abdominal sepsis are associated with significant morbidity and mortality. Microcirculation in the gut is disrupted in hemorrhagic and septic shock leading to tissue hypoxia, and the damaged gut acts as a reservoir rich in inflammatory mediators and provides a continual source of inflammation to the systemic circulation leading to sepsis. Sepsis is defined as the presence (probable or documented) of infection together with a systemic inflammatory response to infection. Blood culture is commonly considered to be the preferred approach for diagnosing sepsis, although it is time-consuming, that is, reports are normally available only after 12-48 hours. …

Neuroscience Faculty Publications

N-glycans and lipids are structural metabolites that play important roles in cellular processes. Both show unique regional distribution in tissues; therefore, spatial analyses of these metabolites are crucial to our understanding of cellular physiology. Matrix-assisted laser desorption/ionization-mass spectrometry imaging (MALDI-MSI) is an innovative technique that enables in situ detection of analytes with spatial distribution. This workflow details a MALDI-MSI protocol for the spatial profiling of N-glycans and lipids from tissues following application of enzyme and MALDI matrix.

For complete details on the use and execution of this protocol, please refer to Drake et al. (2018) and Andres et al. (2020).
