Cohesin gene mutations occur in many malignancies, including acute myeloid leukemia (AML). Loss-of-function mutations in the four major cohesin complex genes (RAD21, SMC3, SMC1a, and STAG2) occur across most major genetic subtypes of AML but are notably absent in AML harboring CBFB::MYH11, suggesting that cohesin mutations yield distinct biological outcomes dependent on the genetic AML driver. We hypothesized that CBFB::MYH11-expressing leukemias would be dependent on intact cohesin genes given their near-mutual exclusivity. To investigate this, we combined either germline or inducible heterozygous deletions in cohesin genes Smc3 or Rad21, respectively, with an inducible murine model of Cbfb::MYH11 AML. This approach …

Nasal colonization by Staphylococcus aureus or Streptococcus pneumoniae is associated with an increased risk of infection by these pathobionts, whereas nasal colonization by Dolosigranulum species is associated with health. Human nasal epithelial organoids (HNOs) differentiated at air-liquid interface (ALI) physiologically recapitulate human nasal respiratory epithelium with a robust mucociliary blanket. Due to their natural stem-like properties, HNO lines are a long-term experimental resource that offers genetic diversity based on the different donors. To develop HNOs as a new model system for bacterial nasal colonization, we reproducibly monocolonized HNOs differentiated at ALI with S. aureus, S. pneumoniae, or Dolosigranulum …

Stem cell niches are essential for regulating stem cell self-renewal and differentiation during tissue repair and regeneration. However, the mechanisms supporting stem cell function in highly regenerative organisms, such as the freshwater planarian Schmidtea mediterranea, remain unclear. Using spatial transcriptomics, we identified two cell types associated with planarian stem cells: secretory cells we term "hecatonoblasts" and intestinal cells. Surprisingly, while hecatonoblasts were in close physical proximity to stem cells in the mesenchyme, they were dispensable for regeneration. In contrast, intestinal cells, despite lacking direct contact with stem cells, regulated both their position and function during regeneration. Electron microscopy revealed diverse …

Compromised Pressure-Generating Capacity Of Diaphragmatic Muscle And Its Interaction With The Lower Rib Cage At High Lung Volume During Airway Occlusion, Aladin M Boriek, Noralis Rodriguez-Santiago, Sanghyun Kim, Aubri Ford, Shari Wynd, Rolf D Hubmayr

Faculty, Staff and Students Publications

The pressure generating capacity of the diaphragm is generally thought to be compromised at high lung volume either due to loss of curvature or loss of its membrane tension. At a state of hyperinflation during airway occlusion at total lung capacity, the diaphragmatic muscle is forced to contract from an initial shorter length, the zone of apposition narrows, insertional force on the chest wall is reduced and abdominal compliance falls. We hypothesize that these altered mechanical conditions at high lung volume lead to a loss of the pressure generating capacity that is mediated by excessive muscle shortening rather than loss …

Implicit Bias Training Standards In Health Care: Did Michigan Get It Right? A Policy And Ethical Framework Analysis, Megan Gailliard, Kieran Fogarty, Mary Lagerwey

The Open Journal of Occupational Therapy

In 2022, Michigan joined a handful of states requiring implicit bias training for its health care professionals. In its ideal application, implicit bias training of health care professionals will result in a reduction of the implicit biases held by health care providers. This bias reduction will, in theory, contribute to improved equity in the delivery of health care services. Ultimately, the less biased health professional, now delivering health care services with a more equitable hand, will help reduce health disparities in the State of Michigan.

This analysis of Mich. Admin. Code R.338.7004 - Implicit bias training standards for licensed and …

Teaching Swimming To Children With Disabilities: A Qualitative Analysis Of Swim Instructorstea, Stephanie S. Garcia-Hidalgo, Martin E. Block

International Journal of Aquatic Research and Education

When teaching children with disabilities, swim instructors need to be able to assess the unique strengths and needs of each child to determine modifications needed to instruction, equipment, and the setting and then be flexible enough to make changes in real-time to ensure success for the child. Unfortunately, many swim instructors only work seasonally and have the occasional child with a disability, and as a result are likely to have limited training and experiences with children with disabilities. The purpose of this pilot qualitative study is to examine backgrounds, training, and experiences of six swim instructors who work with children …

Promising Practices For Increasing The Number Of Equity-Owed Lifeguards In Canada And The United States Of America, Sofia Pantano, Audrey R. Giles

International Journal of Aquatic Research and Education

Currently a shortage of lifeguards exists in Canada and the United States (US) (Frommer, 2023; Santucci, 2024), and those who are working as lifeguards often do not reflect the diversity of the communities they serve (Martinez, 2020). Increasing the number of lifeguards from equity-owed groups is a potential way of increasing the lifeguard workforce and decreasing the shortage of workers in these important roles, as well as a moral imperative.

Faculty, Staff and Students Publications

Purpose: Purine metabolism is a promising therapeutic target in cancer; however, how cancer cells respond to purine shortage, particularly their adaptation and vulnerabilities, remains unclear.

Experimental design: Using the recently developed purine shortage-inducing prodrug DRP-104 and genetic approaches, we investigated the responses in prostate, lung, and glioma cancer models.

Results: We demonstrate that when de novo purine biosynthesis is compromised, cancer cells employ microtubules to assemble purinosomes, multiprotein complexes of de novo purine biosynthesis enzymes that enhance purine biosynthesis efficiency. Although this process enables tumor cells to adapt to purine shortage stress, it also renders them more susceptible to the …

Stereoelectroencephalography Reveals Neural Signatures Of Multisensory Integration In The Human Superior Temporal Sulcus During Audiovisual Speech Perception, Yue Zhang, John F Magnotti, Xiang Zhang, Zhengjia Wang, Yingjia Yu, Kathryn A Davis, Sameer A Sheth, H Isaac Chen, Daniel Yoshor, Michael S Beauchamp

Faculty, Staff and Students Publications

Human speech perception is multisensory, integrating auditory information from the talker's voice with visual information from the talker's face. BOLD fMRI studies have implicated the superior temporal gyrus (STG) in processing auditory speech and the superior temporal sulcus (STS) in integrating auditory and visual speech, but as an indirect hemodynamic measure, fMRI is limited in its ability to track the rapid neural computations underlying speech perception. Using stereoelectroencephalography (sEEG) electrodes, we directly recorded from the STG and STS in 42 epilepsy patients (25F, 17M). Participants identified single words presented in auditory, visual, and audiovisual formats with and without added auditory …

B cells express many protein ligands, yet their regulatory functions are incompletely understood. We profiled ligand expression across murine B sublineage cells, including those activated by defined receptor signals, and assessed their regulatory capacities and specificities through in silico analysis of ligand-receptor interactions. Consequently, we identified a B cell subset that expressed cytokine interleukin-27 (IL-27) and chemokine CXCL10. Through the IL-27–IL-27 receptor interaction, these IL-27/CXCL10-producing B cells targeted CD40-activated B cells in vitro and, upon induction by immunization and viral infection, optimized antibody responses and antiviral immunity in vivo. Also present in breast cancer tumors and retained there through CXCL10-CXCR3 …
