Lasalocid A Selectively Induces The Degradation Of Myd88 In Lymphomas Harboring The Myd88 L265p Mutation, Dafei Chai, Xiaohui Xie, Ken H Young, Ya Cao, Yong Li, Xinfang Yu

Faculty, Staff and Students Publications

Myeloid differentiation primary response protein 88 (MYD88) is a key adaptor molecule in the signaling pathways of toll-like receptor and interleukin-1 receptor. A somatic mutation resulting in a leucine-to-proline change at position 265 of the MYD88 protein (MYD88 L265P) is one of the most prevalent oncogenic mutations found in patients with hematological malignancies. In this study, we used high-throughput screening to identify lasalocid A as a potent small molecule that selectively inhibited the viability of lymphoma cells expressing MYD88 L265P and the associated activation of NF-κB. Further investigations using CRISPR-CRISPR-associated protein 9 genetic screening, proteomics, and biochemical assays revealed that …

Transcriptome-wide association studies (TWASs) have the potential to identify susceptibility genes associated with testicular germ cell tumors (TGCTs). We conducted a comprehensive TGCT TWAS by integrating genome-wide association study (GWAS) summary data with predicted expression models from normal testis, TGCT tissues, and a cross-tissue panel that encompasses shared regulatory features across 22 normal tissues, including the testis. Gene associations were evaluated while accounting for variant-level effects from GWASs, followed by fine-mapping analyses in regions exhibiting multiple TWAS signals, and finally supplemented by colocalization analysis. Expression and protein patterns of identified TWAS genes were further examined in relevant tissues. Our analysis …

The histone H3K36-specific methyltransferase ASH1L plays a critical role in development and is frequently dysregulated in human diseases, particularly cancer. Here, we report on the biological functions of the C-terminal region of ASH1L encompassing a bromodomain (ASH1LBD), a plant homeodomain (ASH1LPHD) finger, and a bromo-adjacent homology (ASH1LBAH) domain, structurally characterize these domains, describe their mechanisms of action, and explore functional crosstalk between them. We find that ASH1LPHD recognizes H3K4me2/3, whereas the neighboring ASH1LBD and ASH1LBAH have DNA binding activities. The DNA binding function of ASH1LBAH is a driving force for the association of ASH1L with the linker DNA in the …

Acute myeloid leukemia (AML) is an aggressive hematopoietic malignancy characterized by the blockage of myeloid cell differentiation and uncontrolled proliferation of immature myeloid cells. Here, we show that paraspeckle component 1 (PSPC1) is aberrantly overexpressed and associated with poor survival in AML patients. Using human AML cells and mouse models, we demonstrate that PSPC1 is not required for normal hematopoiesis, but it is critical and essential for AML cells to maintain their leukemic characteristics. PSPC1 loss induces robust differentiation, suppresses proliferation, and abolishes leukemogenesis in diverse AML cells. Mechanistically, PSPC1 exerts a pro-leukemia effect by regulating a unique leukemic transcription …

Currently, little guidance exists on how to best tailor the implementation strategies to a specific context. This study protocol describes the comprehensive …

Factors Driving Adolescent Tuberculosis Incidence By Age And Sex In 30 High-Tuberculosis Burden Countries: A Mathematical Modelling Study, Peter J Dodd

Faculty, Staff and Students Publications

INTRODUCTION: During adolescence, tuberculosis incidence rises, with a greater increase in males compared with females. Tuberculosis notifications and estimates infrequently disaggregate adolescent age groups. Moreover, the factors that drive the increases in overall incidence and the male-to-female (MF) ratio remain unclear.

METHODS: We constructed a mechanistic model to estimate cumulative Mycobacterium tuberculosis infection and tuberculosis disease incidence in the WHO’s 30 high-tuberculosis burden countries (HBCs), which represent 86%–90% of global tuberculosis incidence. We derived infection risk from tuberculosis prevalence and assortative social mixing based on sex and age (10–14 years vs 15–19 years old). We adjusted age subgroup-specific risks of …

Gene therapy with adeno-associated virus (AAV) vectors requires knowledge of their tropism within the body. Here we analyze the tropism of 10 naturally occurring AAV serotypes (AAV3B, AAV4, AAV5, AAV6, AAV7, AAV8, AAV9, AAVrh8, AAVrh10, and AAVrh74) following systemic delivery into male and female mice. A transgene-expressing ZsGreen and Cre recombinase was used to identify transduction in a cell-dependent manner based on fluorescence. Cre-driven activation of tdTomato fluorescence offered superior sensitivity for transduced cells. All serotypes except AAV3B and AAV4 had high liver tropism. Fluorescence activation revealed transduction of unexpected tissues, including adrenals, testes, and ovaries. Rare transduced cells within …

2020-Current year OA Pubs

INTRODUCTION: Endometriosis affects 10-15% of people assigned female at birth and can cause chronic pelvic pain and impair many domains of quality of life, such as fertility, mood and bladder, bowel and sexual function. Current treatments often fail, leading to recurrent pain and the need for reintervention. As endometriosis negatively affects many domains of life, a variety of non-pharmacological treatments modestly improve symptoms. To bundle these interventions into accessible packaging, our interdisciplinary team developed a novel endometriosis intervention titled 'Peer-Empowered Endometriosis Pain Support (PEEPS)', an 8-week integrative group care intervention. Here, we present the protocol for a pilot randomised controlled …

Carm1 Regulates Tubulin Autoregulation Through Pi3kc2Α R175 Methylation, Yena Cho, Jee Won Hwang, Mark T Bedford, Dae-Geun Song, Su-Nam Kim

Faculty, Staff and Student Publications

Tubulin is crucial in several cellular processes, including intracellular organization, organelle transport, motility, and chromosome segregation. Intracellular tubulin concentration is tightly regulated by an autoregulation mechanism, in which excess free tubulin promotes tubulin mRNA degradation. However, the details of how changes in free tubulin levels initiate this autoregulation remain unclear. In this study, we identified coactivator-associated arginine methyltransferase 1 (CARM1)-phosphatidylinositol 3-kinase class 2α (PI3KC2α) axis as a novel regulator of tubulin autoregulation. CARM1 stabilizes PI3KC2α by methylating its R175 residue. Once PI3KC2α is not methylated, it becomes unstable, leading to decreased cellular levels. Loss of PI3KC2α results in the release …

Photoacoustic Imaging For Image-Guided Gastric Tube Placement: Ex Vivo Characterization, Samuel John, Yeidi Yuja Vaquiz, Nikhila Nyayapathi, Loay Kabbani, Anoop Nilam, Nicole A Wilson, Mohammad Mehrmohammadi

Faculty, Staff and Student Publications

Over 250,000 gastrostomy tubes (G-tubes) are placed annually in the United States. Percutaneous endoscopic gastrostomy (PEG) is the most widely used clinical method for placing G-tubes within the stomach. However, endoscope detectability is limited due to the scattering of light by tissues. Poor organ visibility and low sensitivity of the palpation techniques cause blind needle insertions, which cause colon/liver perforations, abdominal bleeding, and gastric resections. Additionally, imaging artifacts and the poor distinguishability between water-filled tissues make ultrasound (US) imaging-based techniques incompatible with G-tube placement. The risk of ionizing radiation exposure and the confinement of fluoroscopy to radiology suites limits its …

Privacy-Preserving Framework For Genomic Computations Via Multi-Key Homomorphic Encryption

Faculty, Staff and Student Publications

Motivation: The affordability of genome sequencing and the widespread availability of genomic data have opened up new medical possibilities. Nevertheless, they also raise significant concerns regarding privacy due to the sensitive information they encompass. These privacy implications act as barriers to medical research and data availability. Researchers have proposed privacy-preserving techniques to address this, with cryptography-based methods showing the most promise. However, existing cryptography-based designs lack (i) interoperability, (ii) scalability, (iii) a high degree of privacy (i.e. compromise one to have the other), or (iv) multiparty analyses support (as most existing schemes process genomic information of each party individually). Overcoming …

Learning Directed Acyclic Graphs For Ligands And Receptors Based On Spatially Resolved Transcriptomic Data Of Ovarian Cancer, Shrabanti Chowdhury, Sammy Ferri-Borgogno, Peng Yang, Wenyi Wang, Jie Peng, Pei Wang

Faculty, Staff and Student Publications

To unravel the mechanism of immune activation and suppression within tumors, a critical step is to identify transcriptional signals governing cell-cell communication between tumor and immune/stromal cells in the tumor microenvironment. Central to this communication are interactions between secreted ligands and cell-surface receptors, creating a highly connected signaling network among cells. Recent advancements in in situ-omics profiling, particularly spatial transcriptomic (ST) technology, provide unique opportunities to directly characterize ligand-receptor signaling networks that power cell-cell communication. In this paper, we propose a novel statistical method, LRnetST, to characterize the ligand-receptor interaction networks between adjacent tumor and immune/stroma cells based on ST …
