Mll3 And Mll4 Sustain Hematopoietic Stem Cell Multipotency By Opposing A B-Cell Default State, Helen C Wang, Ran Chen, Wei Yang, Rohini Muthukumar, Tingting Hu, Riddhi M Patel, Emily B Casey, Elisabeth Denby, Run Zhang, Guojia Xie, Kai Ge, Grant A Challen, Jeffrey J Bednarski, Jeffrey A Magee

2020-Current year OA Pubs

Hematopoietic stem cells (HSCs) and multipotent progenitors (MPPs) are sustained by networks of transcription factors and epigenetic regulators that prime lineage-specific programs yet maintain multipotency. Two epigenetic regulators, MLL3 and MLL4, play important but distinct roles in maintaining this balance. MLL3 promotes HSC differentiation, whereas MLL4 opposes differentiation. These activities are essential for both normal homeostasis and leukemia suppression, yet it is not clear how MLL3 and MLL4 regulate HSC and MPP gene expression to control HSC/MPP fate decisions. To resolve these mechanisms, we performed an extensive series of single-cell genomic studies after conditionally deleting Mll3, Mll4 or both genes …

Loss Of Pleasure (Anhedonia): A Sex-Dependent, Cross-Species Consequence Of Unpredictable Signals To The Perinatal Brain, Anna M. Zhou, Madison R. Tetzlaff, Laura M. Glynn, Curt A. Sandman, Hal S. Stern, Tallie Z. Baram, Elysia Poggi Davis

Psychology Faculty Articles and Research

Reward seeking is an essential component of human behavior. Anhedonia (reduced motivation for and pleasure in reward) is a core feature of several mental illnesses. Early life adversity associates with later impairments in reward behaviors and related psychopathology; however, specific aspects of early adversity that lead to disrupted reward behaviors are unknown. Capitalizing on evidence that unpredictable signals to the developing brain constitute adversity and influence neurodevelopment, we examined whether exposure to perinatal unpredictable maternal signals associated with diminished reward responsivity, and probed causality using experiments in mice. We analyzed a longitudinal human study (N=158 mother/child dyads) and a …

Intermembrane Coupling Between Bcl-Xl And The Ip3 Receptor Supports Local Ca2+ Transfer At Er-Mitochondrial Contacts, Arijita Ghosh, David Weaver, Chi Li, György Hajnóczky

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Bcl-xL, an anti-apoptotic Bcl-2 family protein, engages laterally with Bak/Bax in the outer mitochondrial membrane (OMM) to inhibit apoptosis and interacts with the IP₃ receptor Ca²⁺ channels (IP3Rs) in the endoplasmic reticulum (ER) membrane to control Ca²⁺ release. It is unknown if OMM-localized Bcl-xL can also interact in trans with IP3Rs at ER-mitochondrial contacts to form a tethering complex that supports IP3R-mediated local Ca²⁺ transfer from ER to mitochondria. We establish that IP3R-mitochondria Ca²⁺ signal propagation depends on Bcl-xL. By targeting Bcl-xL specifically to different subcellular compartments, we find that OMM-localized Bcl-xL increases the efficacy …

Cracking The Code: The Systematic Development Of A Coding Matrix For Qualitative Data Analysis, Greta Gray, Marie-Christine Potvin

Department of Occupational Therapy Faculty Papers

A systematic approach was used to develop a coding matrix for a qualitative study with the intent to strengthen the credibility and dependability of the findings. Coding matrixes are commonly used in qualitative studies to organize data into meaningful units of text to be interpreted by the researchers. Current methods of coding matrix development can be problematic as they may introduce biases in the results and have limited reproducibility. A novel approach was employed to address this need with the “a priori” development of a coding matrix using a multi-step deductive and inductive process with multi-coders (n=5).  The coders who …

Dosimetric Impact Of Eclipse’S Entrance Avoidance Tool On Salivary Gland Sparing In Head And Neck Vmat Plans, Shannon Diederichs

Masters Projects

Medical dosimetry is constantly evolving as new techniques emerge to improve plan quality. The Eclipse treatment planning system (TPS) is equipped with the entrance and exit dose avoidance tool commonly used to prevent beam interaction with implanted metals or steer the beam away from anatomical regions. Current literature shows this tool has not been thoroughly investigated for more fundamental applications such as routine organ at risk (OAR) sparing. Xerostomia remains a lasting side effect for head-and-neck cancer (HNC) patients after the salivary glands receive substantial radiation. This study takes a more detailed look at the tool’s effectiveness when applied to …

Environmental Exposure Risk Education To Enhance Chronic Kidney Disease Prevention And Screening For Nurse Practitioners, Kelsea J. Carrier

Doctor of Nursing Practice Scholarly Projects

Chronic kidney disease (CKD) affects approximately 36 million adults in the United States, with nearly 90% of individuals unaware of their diagnosis until advanced stages. While diabetes and hypertension remain the primary causes, increasing evidence highlights environmental exposures as significant and underrecognized contributors to CKD onset and progression. Exposures such as heavy metals, per- and polyfluoroalkyl substances (PFAS), air and water pollution, microplastics, and heat exposure have been linked to impaired renal function. Despite this growing body of evidence, environmental health content remains limited in nursing education, resulting in gaps in environmental health literacy (EHL) among nurse practitioners (NPs) and …

Research outputs 2022 to 2026

Introduction – Pain assessment remains challenging in healthcare settings in patients who are unable to self-report their pain. More than 50% of individuals with dementia and other forms of cognitive impairment (CI) experience pain daily. However, pain is frequently overlooked and inadequately assessed by healthcare professionals due to their lack of knowledge and guidelines to inform pain assessment. Pain is also a leading cause of hospital presentation and inappropriate pain assessment can impact on pain management and compromise safe and quality care. Evidence-based guidelines that inform appropriate pain assessment and management are therefore essential. This scoping review aimed to explore …

Myeloid Mmp14 Couples Extracellular Proteolysis To Inflammatory And Metabolic Remodeling During Obesity, Long J Shao, Fathima Elizondo, Feng Gao, Elizabeth L Lieu, Bharati Reddi, Maryam Elizondo, Iqbal Mahmud, Kristin Eckel-Mahan, Philipp E Scherer, Xin Ge, Huaizhu Wu, Sean Hartig, Kai Sun

The Brown Foundation: Institute of Molecular Medicine

Macrophages orchestrate tissue remodeling, inflammation, and metabolic dysfunction in obesity, but the role of macrophage-intrinsic extracellular proteolysis in immunometabolic regulation remains unclear. Matrix metalloproteinase-14 (MMP14), a membrane-bound protease, is strongly induced during monocyte-to-macrophage differentiation and further elevated in adipose tissue macrophages from high-fat diet (HFD)-fed mice. Pharmacological inhibition or myeloid-specific deletion of Mmp14 impaired macrophage differentiation, proliferation, migration, phagocytosis, and inflammatory activation in response to obesity-associated adipose tissue signals. Mechanistically, MMP14 promoted inflammatory programming by increasing endotrophin generation and enhancing TLR4-NFκB signaling. MMP14 also reprogrammed macrophage lipid metabolism by suppressing lipolysis and promoting lipid accumulation, altering metabolic communication with neighboring …

PCOM Scholarly Works

Cancer therapy-related cognitive impairment (CTRCI) is a debilitating neurotoxic condition adversely impacting cancer patients during and post-cancer treatments. The cancer treatments linked to CTRCI include chemotherapy, hormone therapy, targeted therapy, and immunotherapy. Despite CTRCI severely affecting the psychological and social, cognitive functions, and the overall quality of life of cancer survivors, no effective medications are available currently. Our prior studies have indicated hippocampal tyrosine phosphatase protein tyrosine phosphatase receptor type O (PTPRO) as a putative target for CTRCI. However, phosphatase is historically considered undruggable, and delivering drugs across the blood-brain barrier (BBB) is challenging. Here, we developed a novel delivery …
