Cookie-Pro: Covalent Inhibitor Binding Kinetics Profiling On The Proteome Scale, Hanfeng Lin, Bin Yang, Lang Ding, Yen-Yu Yang, Matthew V Holt, Sung Yun Jung, Bing Zhang, Meng C Wang, Jin Wang

Faculty, Staff and Students Publications

Covalent inhibitors are an emerging class of therapeutics, but methods to comprehensively profile their binding kinetics and selectivity across the proteome have been limited. Here we introduce COOKIE-Pro (COvalent Occupancy KInetic Enrichment via Proteomics), an unbiased method for quantifying irreversible covalent inhibitor binding kinetics on a proteome-wide scale. COOKIE-Pro uses a two-step incubation process with mass spectrometry-based proteomics to determine kinact and KI values for covalent inhibitors against both on-target and off-target proteins. We validated COOKIE-Pro using BTK inhibitors spebrutinib and ibrutinib, accurately reproducing known kinetic parameters and identifying both expected and unreported off-targets. The method revealed that …

Acinetobacter baumannii is recognized as the paradigm of multidrug-resistant superbug, topping the WHO priority list of critical human pathogens. Interestingly, it senses and responds to blue light, which modulates global aspects of its physiology, including pathogenicity. We hypothesized that light could serve as a signal to synchronize the bacterial physiology to the host's behavior and/or to the environment. At environmental temperatures, light regulation is mainly governed by the photoreceptor BlsA. In this work, we identified the existence of daily rhythms in blsA promoter activity displaying a robust response to light, as well as endogenous circadian rhythms in A. baumannii. In …

Current States In Understanding Oligodendroglia-Mediated Neurological Issues In Neurofibromatosis Type 1 (Nf1), Benjamin E Aghoghovwia, Cheng-En Shen, Sabiha Bano, Nandini Shyamala, Alesandra Echeandia Marrero, Khushboo Irshad, Samer Sharafaldin, Nicole M Brossier, Yuan Pan

Faculty, Staff and Student Publications

Neurofibromatosis type 1 (NF1) is among the most common neurogenetic disorders and is associated with an increased risk of developing tumors in the nervous system. Additionally, up to 80% of patients with NF1 experience neurological complications, including deficits in attention, memory, and executive function. Significant effort has been dedicated to studying how NF1 mutations autonomously dysregulate neuronal function. Increasing evidence indicates that NF1 mutations also dysregulate the oligodendroglial lineage that contributes to neurological issues in NF1. Here, we summarize our current understanding of how NF1 mutations impact the oligodendroglial lineage homeostasis and plasticity. We also discuss gaps in knowledge, potential …

In-scanner head motion introduces systematic bias to resting-state fMRI functional connectivity (FC) not completely removed by denoising algorithms. Researchers studying traits associated with motion (e.g. psychiatric disorders) need to know if their trait-FC relationships are impacted by residual motion to avoid reporting false positive results. We devised Split Half Analysis of Motion Associated Networks (SHAMAN) to assign a motion impact score to specific trait-FC relationships. SHAMAN distinguishes between motion causing overestimation or underestimation of trait-FC effects. We assessed 45 traits from n = 7270 participants in the Adolescent Brain Cognitive Development (ABCD) Study. After standard denoising with ABCD-BIDS and without …

Imaging-based spatial transcriptomics (ST) is evolving as a pivotal technology in studying tumor biology and associated microenvironments. However, the strengths of the commercially available ST platforms in studying spatial biology have not been systematically evaluated using rigorously controlled experiments. We use serial 5 μm sections of formalin-fixed, paraffin-embedded surgically resected lung adenocarcinoma and pleural mesothelioma samples in tissue microarrays to compare the performance of the ST platforms (CosMx, MERFISH, and Xenium (uni/multi-modal)) in reference to bulk RNA sequencing, multiplex immunofluorescence, GeoMx, and hematoxylin and eosin staining data. In addition to an objective assessment of automatic cell segmentation and phenotyping, we …

The interaction of host and Ebola virus (EBOV) proteins is required for establishing infection. In this study, we use proximity-dependent biotinylation to identify cellular proteins that bind to EBOV proteins encoded by six of the seven viral genes. Hits are computationally mapped onto a human protein-protein interactome and annotated with viral proteins, confirming known EBOV-host protein interactions and revealing previously undescribed interactions and processes. This approach efficiently arranges proteins into functional complexes associated with single viral proteins. Focused characterization of interactions between EBOV VP35 and the mRNA decapping complex shows that VP35 binds the scaffold protein EDC4 through the C-terminal …

Antibiotic resistance is a threat to human health, yet recent work highlights how loss of resistance may drive pathogenesis in some bacteria. In two recent studies, we found that β-lactam antibiotics and nutrient stresses faced during infection selected for genetic inactivation of the Pseudomonas aeruginosa antibiotic efflux pump mexEFoprN. Unexpectedly, efflux pump mutations increased P. aeruginosa virulence during infection; however, neither the prevalence of mexEFoprN inactivating mutations in real human infections, nor the mechanisms driving increased virulence of efflux pump mutants are known. We hypothesized that human infection would select for virulence enhancing mutations. Using genome sequencing of clinical isolates, …

EGFRex20 insertions (EGFRex20ins) can be classified as near- and far-loop based on the insertion location, however, the impact of location on responses to various EGFR tyrosine kinase inhibitors (TKIs) is poorly understood. In vitro studies show that afatinib, poziotinib, and zipalertinib more potently inhibited near-loop than far-loop insertions, whereas mobocertinib has similar IC50 in both groups. Molecular dynamics simulations reveal that near-loop insertions have multiple conformational states and lower transitional energy than far-loop insertions. ZENITH20 trial cohort 1 (NCT03318939) evaluates poziotinib in EGFRex20 NSCLC patients (n = 115) and demonstrates an objective response rate of 14.8% (95% Confidence …

To better characterize the potential biological mechanisms underlying insulin resistance (IR) and dementia, we derive cross-population and population specific polygenic scores [PSs] for fasting insulin and IR-related partitioned PSs [pPSs]. We conduct a cross-sectional study of the associations of these genetic scores with neurological outcomes in >17k participants (36% men, mean age 55 yrs) from the Trans-Omics for Precision Medicine (TOPMed) program (50% Non-Hispanic White, 23% Black/African American, 21% Hispanic/Latino American, and 4% Asian American). We report significant negative associations (P <  0.002) of the cross-population (P = 1.3 × 10-5) and European (PEA = 3.0 × 10-8) fasting insulin PSs with total cranial volume, and of a metabolic syndrome European PS with general cognitive function (BEA = -0.13, PEA = 0.0002) and lateral ventricular volume (BEA = 0.09, PEA = 0.002). We identify suggestive negative associations (P <  0.007) of metabolic syndrome and obesity pPSs with general cognitive function, and of lipodystrophy pPSs with total cranial volume. A higher genetic predisposition to IR is associated with lower brain size, and a genetic predisposition to specific IR-related type 2 diabetes subtypes, such as metabolic syndrome and mechanisms of IR mediated through obesity and lipodystrophy, is potentially involved in cognitive decline.

Site-1 Protease Is A Negative Regulator Of Sarcolipin Promoter Activity, Isha Sharma, Meredith O Kelly, Katelyn Hanners, Ella S Shin, Muhammad G Mousa, Shelby Ek, Gretchen A Meyer, Rita T Brookheart

2020-Current year OA Pubs

The timed contraction and relaxation of myofibers in tissues such as the heart and skeletal muscle occur via the tightly regulated movement of calcium ions into and out of the sarcoplasmic reticulum (SR). In skeletal muscle, this phenomenon enables humans to exercise, perform day-to-day tasks, and to breathe. Sarcolipin, a small regulatory protein, prevents calcium ions from entering the SR by binding to and inhibiting SERCA, contributing to myofiber contraction. Disruptions in sarcolipin (SLN) expression are implicated in the pathophysiology of obesity and musculoskeletal disease. However, the mechanisms regulating sarcolipin expression are not clearly understood. We recently showed that site-1 …

What Is Known About The Fish Intake Of People Living In Disadvantaged Communities In The Uk? A Scoping Review, Sarah Gale, Roseline Aboluwade, Louise Hunt, Clare Pettinger

School of Health Professions

Fish provides essential nutrients, including protein, omega-3 fatty acids (oily fish) and other micronutrients, and may be seen to have a prominent role in protecting against non-communicable diseases, especially cardiovascular disease. Recent UK National Diet and Nutrition Survey analysis suggests people are not meeting their weekly fish intake recommendation of at least two portions per week, of which one should be oily. Lower socioeconomic groups are more likely to eat poor-quality diets, with low fish intake, resulting in poor health outcomes. The aim of this scoping review was to examine the factors influencing fish consumption in people living within ‘disadvantaged …

More than 20 genes expressed in the male reproductive tract have been identified as essential factors for sperm migration to and through the utero-tubal junction (UTJ), and they are divided into ADAM3-dependent and ADAM3-independent pathways. In parallel, sperm having UTJ migration defects also show impaired binding to the zona pellucida (ZP). Herein, we demonstrate that knockout of Galntl5, encoding a sperm surface protein, causes impaired sperm binding with the UTJ and ZP, and null males have severe infertility. GALNTL5 appreciably disappears in sperm lacking Adam3 or Lypd4, required for ADAM3-dependent and ADAM3-independent pathways, and GALNTL5 binds to N …

Faculty, Staff and Student Publications

Histone H3 trimethylation at lysine 36 (H3K36me3) is a key chromatin modification that regulates fundamental physiological and pathological processes. In humans, SETD2 is the only known enzyme that catalyzes H3K36me3 in somatic cells and is implicated in tumor suppression across multiple cancer types. While there is considerable crosstalk between the SETD2-H3K36me3 axis and other epigenetic modifications, much remains to be understood. Here, we show that Setd2 functions as a potent tumor suppressor in a KRASG12C-driven lung adenocarcinoma (LUAD) mouse model, and that acetylation enhances SETD2 in vitro methylation of H3K36 on nucleosome substrates. In vivo, Setd2 ablation accelerates lethality in …
