The Tudor-Knot Domain Of Kat5 Regulates Nucleosomal Substrate Acetylation, Fan Xuan, Hongwen Xuan, Mengying Huang, Wei He, Han Xu, Hong Wen

Faculty, Staff and Student Publications

The lysine acetyltransferase KAT5 is a pivotal enzyme responsible for catalyzing histone H4 acetylation in cells. In addition to its indispensable HAT domain, KAT5 also encompasses a conserved Tudor-knot domain at its N-terminus. However, the function of this domain remains elusive, with conflicting findings regarding its role as a histone reader. In our study, we have employed a CRISPR tiling array approach and unveiled the Tudor-knot motif as an essential domain for cell survival. The Tudor-knot domain does not bind to histone tails and is not required for KAT5's chromatin occupancy. However, its absence leads to a global reduction in …

Intraprocedural Versus Initial Follow-Up Minimal Ablative Margin Assessment After Colorectal Liver Metastasis Thermal Ablation: Which One Better Predicts Local Outcomes?, Yuan-Mao Lin, Iwan Paolucci, Jessica Albuquerque Marques Silva, Caleb S O'Connor, Bryan M Fellman, Joshua D Kuban, Zeyad A Metwalli, Kristy K Brock, Bruno C Odisio

E-Cadherin Loss Drives Diffuse-Type Gastric Tumorigenesis Via Ezh2-Mediated Reprogramming, Gengyi Zou, Yuanjian Huang, Shengzhe Zhang, Kyung-Pil Ko, Bongjun Kim, Vishwa Venkatesan, Yibo Fan, Sohee Jun, Na Niu, Huamin Wang, Shumei Song, Jaffer A Ajani, Jae-Il Park

Faculty, Staff and Student Publications

Diffuse-type gastric adenocarcinoma (DGAC) is a deadly cancer often diagnosed late and resistant to treatment. While hereditary DGAC is linked to CDH1 mutations, the role of CDH1/E-cadherin inactivation in sporadic DGAC tumorigenesis remains elusive. We discovered CDH1 inactivation in a subset of DGAC patient tumors. Analyzing single-cell transcriptomes in malignant ascites, we identified two DGAC subtypes: DGAC1 (CDH1 loss) and DGAC2 (lacking immune response). DGAC1 displayed distinct molecular signatures, activated DGAC-related pathways, and an abundance of exhausted T cells in ascites. Genetically engineered murine gastric organoids showed that Cdh1 knock-out (KO), KrasG12D, Trp53 KO (EKP) accelerates tumorigenesis with immune evasion …

Genome-Wide Crispr Screen Reveals The Synthetic Lethality Between Bcl2l1 Inhibition And Radiotherapy, Ling Yin, Xiaoding Hu, Guangsheng Pei, Mengfan Tang, You Zhou, Min Huang, Jie Zhang, Citu Citu, Zhongming Zhao, Bisrat G Debeb, Xu Feng, Junjie Chen

Faculty, Staff and Student Publications

Radiation therapy (RT) is one of the most commonly used anticancer therapies. However, the landscape of cellular response to irradiation, especially to a single high-dose irradiation, remains largely unknown. In this study, we performed a whole-genome CRISPR loss-of-function screen and revealed temporal inherent and acquired responses to RT. Specifically, we found that loss of the IL1R1 pathway led to cellular resistance to RT. This is in part because of the involvement of radiation-induced IL1R1-dependent transcriptional regulation, which relies on the NF-κB pathway. Moreover, the mitochondrial anti-apoptotic pathway, particularly the BCL2L1 gene, is crucially important for cell survival after radiation. BCL2L1 …

Population Coding Of Strategic Variables During Foraging In Freely Moving Macaques, Neda Shahidi, Melissa Franch, Arun Parajuli, Paul Schrater, Anthony Wright, Valentin Dragoi

Faculty, Staff and Student Publications

Until now, it has been difficult to examine the neural bases of foraging in naturalistic environments because previous approaches have relied on restrained animals performing trial-based foraging tasks. Here we allowed unrestrained monkeys to freely interact with concurrent reward options while we wirelessly recorded population activity in the dorsolateral prefrontal cortex. The animals decided when and where to forage based on whether their prediction of reward was fulfilled or violated. This prediction was not solely based on a history of reward delivery, but also on the understanding that waiting longer improves the chance of reward. The task variables were continuously …

BACKGROUND: Single-agent immune checkpoint inhibitors (ICIs) have demonstrated limited responses in recurrent ovarian cancer; however, 30%-40% of patients achieve stable disease. The primary objective was to estimate progression-free survival (PFS) after sequential versus combination cytotoxic T-lymphocyte antigen 4 and programmed death ligand 1 ICIs in patients with platinum-resistant high-grade serous ovarian cancer (HGSOC).

METHODS: Patients were randomized to a sequential arm (tremelimumab followed by durvalumab on progression) or a combination arm (tremelimumab plus durvalumab, followed by durvalumab) via a Bayesian adaptive design that made it more likely for patients to be randomized to the more effective arm. The primary end …

Exercise-Induced Myc As An Epigenetic Reprogramming Factor That Combats Skeletal Muscle Aging, Ronald G. Jones Iii, Ferdinand Von Walden, Kevin A. Murach

Health, Human Performance and Recreation Faculty Publications and Presentations

Of the “Yamanaka factors” Oct3/4, Sox2, Klf4, and c-Myc (OSKM), the transcription factor c-Myc (Myc) is the most responsive to exercise in skeletal muscle and is enriched within the muscle fiber. We hypothesize that the pulsatile induction of MYC protein after bouts of exercise can serve to epigenetically reprogram skeletal muscle toward a more resilient and functional state.

Calcific aortic stenosis can be considered a model for geriatric cardiovascular conditions due to a confluence of factors. The remarkable technological development of transcatheter aortic valve replacement was studied initially on older adult populations with prohibitive or high-risk for surgical valve replacement. Through these trials, the cardiovascular community has recognized that stratification of these chronologically older adults can be improved incrementally by invoking the concept of frailty and other geriatric risks. Given the complexity of the aging process, stratification by chronological age should only be the initial step but is no longer sufficient to optimally quantify cardiovascular and noncardiovascular risk. …

How Territoriality And Sociality Influence The Habitat Selection And Movements Of A Large Carnivore, J Weldon Mcnutt

Faculty, Staff and Student Publications

While territoriality is one of the key mechanisms influencing carnivore space use, most studies quantify resource selection and movement in the absence of conspecific influence or territorial structure. Our analysis incorporated social information in a resource selection framework to investigate mechanisms of territoriality and intra‐specific competition on the habitat selection of a large, social carnivore. We fit integrated step selection functions to 3‐h GPS data from 12 collared African wild dog packs in the Okavango Delta and estimated selection coefficients using a conditional Poisson likelihood with random effects. Packs selected for their neighbors' 30‐day boundary (defined as their 95% kernel …

Combined Ion Beam Irradiation Platform And 3d Fluorescence Microscope For Cellular Cancer Research, Guy Garty, Wenze Li, Gary W Johnson, Sally A Amundson, Peter W Grabham, Elizabeth M C Hillman, David J Brenner

Faculty, Staff and Student Publications

To improve particle radiotherapy, we need a better understanding of the biology of radiation effects, particularly in heavy ion radiation therapy, where global responses are observed despite energy deposition in only a subset of cells. Here, we integrated a high-speed swept confocally-aligned planar excitation (SCAPE) microscope into a focused ion beam irradiation platform to allow real-time 3D structural and functional imaging of living biological samples during and after irradiation. We demonstrate dynamic imaging of the acute effects of irradiation on 3D cultures of U87 human glioblastoma cells, revealing characteristic changes in cellular movement and intracellular calcium signaling following ionizing irradiation.

Recurrent Nontraumatic Subgaleal Hematomas In A Pediatric Patient With Sickle Cell Disease, Monica Kodakandla

Faculty, Staff and Student Publications

Spontaneous subgaleal hematoma in pediatric patients with sickle cell disease (SCD) is a rare occurrence that can present with symptoms mimicking ischemic stroke, a known complication of SCD. However, unlike ischemic stroke, subgaleal hematoma is nonlethal and can be managed conservatively without major sequelae. Here, we present the case of an adolescent with SCD who presented with 2 episodes of subgaleal and epidural hematomas, 2 years apart. The latter episode occurred while on crizanlizumab, an anti-P-selectin antibody, approved for use in SCD in 2019 to reduce the number of acute pain crises. We demonstrate the diagnosis of subgaleal hematoma and …

Congenital Disseminated Malignant Rhabdoid Tumor Mimicking A Vascular Lesion

Faculty, Staff and Student Publications

A congenital disseminated malignant rhabdoid tumor (MRT) is an exceedingly rare and aggressive pediatric cancer marked by the presence of malignant rhabdoid cells in various organs, including the brain, kidneys, and soft tissues, at birth. It is often detected prenatally or shortly post-birth. The malignancy's aggressiveness results in a bleak prognosis, offering limited treatment options and low survival rates. Early diagnosis and comprehensive medical intervention are crucial, but managing this condition is complicated by its rarity. We herein presented a case of a 37 and 1/7 week gestation male infant with a rapidly growing arm soft tissue mass within two …

Faculty, Staff and Student Publications

Patients with both BRAF V600E mutations and microsatellite instability-high (MSI-H)/mismatch repair-deficient (dMMR) metastatic colorectal cancer (mCRC) have poor prognosis. Currently, there are no specifically targeted first-line treatment options indicated for patients with mCRC whose tumors harbor both molecular aberrations. Pembrolizumab is a checkpoint inhibitor approved for the treatment of MSI-H/dMMR mCRC, and the BRAF inhibitor encorafenib, in combination with cetuximab, is approved for previously treated BRAF V600E-mutant mCRC. Combination of pembrolizumab with encorafenib and cetuximab may synergistically enhance antitumor activity in patients with BRAF V600E-mutant, MSI-H/dMMR mCRC. SEAMARK is a randomized phase II study comparing the efficacy of the combination …

Cytoplasmic Redox Imbalance In The Thioredoxin System Activates Hsf1 And Results In Hyperaccumulation Of The Sequestrase Hsp42 With Misfolded Proteins

Faculty, Staff and Student Publications

Cells employ multiple systems to maintain homeostasis when experiencing environmental stress. For example, the folding of nascent polypeptides is exquisitely sensitive to proteotoxic stressors including heat, pH, and oxidative stress, and is safeguarded by a network of protein chaperones that concentrate potentially toxic misfolded proteins into transient assemblies to promote folding or degradation. The redox environment itself is buffered by both cytosolic and organellar thioredoxin and glutathione pathways. How these systems are linked is poorly understood. Here, we determine that specific disruption of the cytosolic thioredoxin system resulted in constitutive activation of the heat shock response in Saccharomyces cerevisiae and …

Pediatric glioma therapy has evolved to delay or eliminate radiation for low-grade tumors. This study examined these temporal changes in therapy with long-term outcomes in adult survivors of childhood glioma. Among 2,501 5-year survivors of glioma in the Childhood Cancer Survivor Study diagnosed 1970-1999, exposure to radiation decreased over time. Survivors from more recent eras were at lower risk of late mortality (≥5 years from diagnosis), severe/disabling/life-threatening chronic health conditions (CHCs) and subsequent neoplasms (SNs). Adjusting for treatment exposure (surgery only, chemotherapy, or any cranial radiation) attenuated this risk (for example, CHCs (1990s versus 1970s), relative risk (95% confidence interval), …
