Inhibition Of The Heg1-Krit1 Interaction Increases Klf4 And Klf2 Expression In Endothelial Cells, Miguel Lopez-Ramirez, Wenqing Li, Mark Haynes, Preston Hale, Sara Mccurdy, Karol Francisco, Killian Oukoloff, Matthew H. Bautista, Chelsea Choi, Hao Sun, Brendan Gongol, John Shyy, Carlo Ballatore, Larry Sklar, Alexandre Gingras

Medical Student Research Symposium

The Kruppel-like Factors 2 and 4 (KLF2/4) are transcription factors and master regulators of endothelial cells (ECs) phenotype and homeostasis. KLF2/4 are important blood-flow-responsive genes within ECs that differentially regulate the expression of factors that confer anti-inflammatory, antithrombotic, and antiproliferative effects in ECs. We found that genetic inactivation of endothelial Krit1 (Krev interaction trapped protein 1) or Heg1 (Heart of glass) led to upregulation of KLF2/4 expression levels. We also observed that vasoprotective proteins, endothelial nitric oxide synthase (eNOS) and thrombomodulin (TM), are upregulated by the increase of KLF2/4 as a result of loss of endothelial KRIT1. Here, we developed …

Mental Health Impact Of The Covid-19 Pandemic On Parents In High-Risk, Low Income Communities, Dana Alonzo, Marciana Popescu, Pinar Zubaroglu Ioannides

Covid-19 Digital Research

COVID-19 has spread across the globe, resulting in significant changes in virtually every aspect of life. Mitigation efforts, like shelter-in-place orders, have taken a particular toll on parents who have had to navigate disruptions in work and/or school schedules. Research from high-income countries demonstrates increased parental anxiety, stress, depression, and burnout resulting from the pandemic. It is unclear if these outcomes are the same for parents in high-risk communities in low-income countries where pre-pandemic conditions were deleterious. This study addresses this gap and examines the mental health impact of the pandemic on parents in high-risk communities in Guatemala.

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 …

The Reflection On The Management Of Toxic Epidermal Necrolysis In The Community Setting: An Internist's Perspective, Qian Zhang, Ali Raza Shaikh, Thomas Yoon, Shreeja Shah Shah, James W. Mahoney

Abington Jefferson Health Papers

Toxic epidermal necrolysis (TEN) is a dermatological emergency that is often associated with high mortality. It is differentiated from Stevens-Johnson syndrome (SJS) based on the percentage of the total body surface area affected. There has been an established correlation with certain medications that could trigger the development of such a devastating disease. Despite numerous research studies conducted on aspects of this disease entity, TEN remains foreign to many general Internists situated in a community setting due to the extremely low disease prevalence that leads to a lack of overall experience and medical resources in dealing with this medical condition.

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, …

Characterization Of Abin-1 In The Traumatically Injured Brain, Aaron Orellana, Alana C. Conti

Medical Student Research Symposium

Traumatic brain injury (TBI) is associated with chronic pain and persistent neuroinflammation. Opioids are often prescribed in order to relieve pain symptoms, but recent evidence suggests that their use negatively impacts the neuropathology of TBI leading to behavioral impairments and exacerbated neuroinflammation. The de-ubiquinating enzyme tumor necrosis factor alpha-induced protein (TNFAIP)3 or A20, inhibits the inflammatory signaling transcription factor nuclear factor (NF)-kB leading to attenuation of the inflammatory response. A20-binding inhibitor of nuclear factor kB (ABIN-1), which physically interacts with A20, also plays a role in the inhibition of NF-kB and is poorly researched in the central nervous system (CNS). …

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 …
