Leveraging Ancestral Recombination Graphs For Scalable Mixed-Model Analysis Of Complex Traits, Jiazheng Zhu, Georgios Kalantzis, Ali Pazokitoroudi, Árni Freyr Gunnarsson, Hrushikesh Loya, Han Chen, Sriram Sankararaman, Pier Francesco Palamara

Faculty, Staff and Student Publications

Recent algorithmic advances have enabled the inference of genome-wide ancestral recombination graphs (ARGs) from large genomic cohorts, providing detailed models of genealogical relatedness along the genome. These inferred ARGs can complement genotype imputation by capturing the effects of unobserved variants, but their use in large-scale linear mixed-model analyses has been computationally prohibitive. Here, we develop methods that leverage the ARG to perform genotype-matrix multiplications in sublinear time and implement scalable randomized algorithms for mixed-model analyses. We introduce ARG-RHE, a randomized Haseman-Elston approach for estimating narrow-sense heritability and performing region-based association testing using ARGs, enabling parallel analysis of multiple quantitative traits. …

Third-Party Effects On Intergroup Trust: The Role Of Punishment/Compensation And Group Regulatory Focus, Xiaowei Geng, Jie Cui, Jie Wang, Feng Zhang, Wei Wang

Faculty, Staff and Student Publications

Intergroup trust refers to a collective prediction and belief among members of one group regarding those of another in intergroup interactions. It plays an important role in avoiding intergroup conflicts, and thereby sustaining social development. This study was designed to investigate the effects of third-party punishment and compensation, as well as group regulatory focus, on intergroup trust. The findings revealed that, at both individual and group levels, prevention-focused groups exhibited higher levels of intergroup trust than promotion-focused groups under third-party compensation conditions. In contrast, under the third-party punishment conditions, promotion-focused groups displayed greater trust than prevention-focused groups, although this difference …

Hyperdensity On Head Ct—An Imaging Review, Ramsis Benjamin, Christian Menard, Erik Larson

School of Medicine Publications

The 3D images derived from non-contrast Computed Tomography (NCCT) scans provide a glimpse into the intra- and extracranial structures, based on the ability of electromagnetic X-rays to penetrate through various tissue densities. The gray matter, for example, possesses a higher density than the white matter, absorbs more X-rays, allows less penetration (attenuation), and thus has larger Hounsfield units (HU), the mathematical value of attenuation coefficient. The CT scanner’s wide availability and ease of use allow for quick assessment of acute neurosurgical abnormalities, such as hemorrhages, mass effect, hydrocephalus, and traumatic injuries. An attenuation value of +60 to +90 HU generally …

A Framework For Assessing The Trustworthiness Of Scientific Research Findings, Brian A Nosek, David B Allison, Kathleen Hall Jamieson, Marcia Mcnutt, A Beau Nielsen, Susan M Wolf

Children’s Nutrition Research Center Staff Publications

Vigorous debate has erupted over the trustworthiness of scientific research findings in a number of domains. The question "what makes research findings trustworthy?" elicits different answers depending on whether the emphasis is on research integrity and ethics, research methods, transparency, inclusion, assessment and peer review, or scholarly communication. Each provides partial insight. We offer a systems approach that focuses on whether the research is accountable, evaluable, well-formulated, has been evaluated, controls for bias, reduces error, and whether the claims are warranted by the evidence. We tie each of these components to measurable indicators of trustworthiness for evaluating the research itself, …

Channel Gating In Bacteriorhodopsin-Like Channelrhodopsins With Contrasting K+ And Na+ Selectivity, Oleg A Sineshchekov, Elena G Govorunova, Hai Li, Yumei Wang, John L Spudich

Faculty, Staff and Student Publications

Two closely homologous channelrhodopsins from Hyphochytrium catenoides, known as HcKCR1 (kalium channelrhodopsin 1) and HcCCR (cation channelrhodopsin), exhibit >100 times different K+/Na+ relative permeabilities and are emerging optogenetic tools for controlling neurons and cardiomyocytes. Key residue motifs and trimeric organization relate them structurally to bacteriorhodopsin-like cation channelrhodopsins (BCCRs). Here, we demonstrate that they utilize a specific gating mechanism previously suggested for the earlier-discovered BCCR from cryptophytes. Using a comparative analysis of transient absorption changes and photocurrents under single-turnover conditions, we identified an early, far-UV-absorbing photocycle intermediate that precedes channel opening in wild-type HcKCR1 and HcCCR. The UV-absorbing product is a …

Faculty, Staff and Students Publications

Mechanisms responsible for skeletal muscle kidney crosstalk have not been defined. We have determined that a circulating mediator, signal regulatory protein α (SIRPα), impairs intracellular insulin-mediated functions. To elucidate the effect of myokine SIRPα on diabetic kidney disease (DKD), flox mice and muscle-specific (m-specific) SIRPα-KO mice were subjected to an obesity-induced model of diabetes, high-fat diet (HFD; 60%) or insulin-deficient hyperglycemia model, streptozotocin (STZ), and were subsequently exposed to anti-SIRPα monoclonal antibodies. In the obesity-induced diabetic mice, serum SIRPα increased. Genetic deletion of muscle SIRPα protected against obesity and improved intracellular insulin signaling in muscle and adipose tissue, with reduced …

Methods

We analyzed 1452 patients with WHO-2 from our international, multicenter database (followed between 1989 and 2019). Outcomes were recurrence (10-year follow-up) and death (5-year follow-up). Risk estimates were obtained using competing risks and survival analysis. Average treatment effects were estimated by G-computation, adjusted for potential confounding by age, sex, Simpson grade, Ki-67 proliferation index, location, country group (universal healthcare or not), …

Ubiquitination-Directed Cytosolic Dna Degradation Governs Cgas-Sting-Mediated Immune Response To Dna Damage, Lei Li, Qi Ye, Jinlu Ma, Zixi Wang, Tianjie Liu, Yuzeshi Lei, Mingming Lu, Jialu Kang, Haohan Xiang, Buyun Li, Shan Xu, Ke Wang, Yule Chen, Jiaqi Chen, Bohan Ma, Wenyue Huang, Mengjiao Cai, Nan Wu, Yanqiang Li, Jiale An, Chongming Jiang, Rui Ye, Jing Liu, Steven H Lin, Yang Gao, Jian Ma, Lei Li

Faculty, Staff and Student Publications

Activation of cGAS-STING signaling in cancer cells requires cytosolic DNA produced by intrinsic or treatment-induced DNA damage. However, clinical efforts to exploit this pathway to improve immunotherapy have yielded limited success, highlighting gaps in understanding the link between DNA damage and immunotherapy. Here, we identify ubiquitination-directed cytosolic DNA degradation as a critical determinant for cGAS-STING activation following DNA damage. Mechanistically, the cytosolic DNA exonuclease TREX1 is degraded by the E3 ubiquitin ligase SPOP but is reversely stabilized by the deubiquitinase USP7. Cancer-associated SPOP mutations or USP7 overexpression elevate TREX1 levels, promoting cytosolic DNA degradation and impairing cGAS-STING-mediated immune activation. Notably, …

The co-evolution of different cell subsets in the progression of precursor lesions to lung adenocarcinoma (LUAD) is incompletely understood. We generated spatial transcriptomic maps of 56 human precursor lesions and LUADs from 25 patients and of an independent cohort of 36 lesions from 19 patients, analyzing a total of 486,519 spots and 5.4 million cells. We identify region-specific programs that distinguish precursors from LUADs. Spatially resolved clonal architectures reveal patient-specific heterogeneity in evolution of precursors to LUADs. We find epithelial alveolar progenitors expressing tumor-associated meta-programs and residing in niches enriched with proinflammatory subsets including IL1B high macrophages. Epithelial-proinflammatory niches are …

Proper regulation of ribosome biogenesis is essential for stem cell function and tissue homeostasis, yet its upstream control in adult intestinal stem cells (ISCs) remains unclear. Here, we identify the WD repeat protein Wdr4 as a key regulator of ISC homeostasis in the Drosophila midgut. Wdr4 cooperates with the methyltransferase Mettl1 to catalyze N⁷-methylguanosine (m⁷G) modification of let-7 miRNA. Wdr4 or Mettl1 depletion disrupts this modification, reducing let-7 levels and aberrantly activating TOR-JNK-dMyc signaling. This drives elevated ribosome biogenesis, ISC overproliferation, misdifferentiation, and intestinal dysplasia. Overexpression of let-7, inhibition of TOR, or suppression of JNK rescues these defects. Importantly, expression …

Faculty, Staff and Student Publications

HER2-low breast cancer (IHC 1+ or 2+ without HER2 gene amplification) is a distinct and understudied subtype. In a cohort of 14,593 early-stage breast cancer patients treated at MD Anderson from 2006 to 2019, 60.4% were HER2-low. Multivariable analysis showed HER2-low status was independently associated with race, histologic subtype, higher nuclear grade and stage, and estrogen receptor (ER) positivity. Among 2464 patients receiving neoadjuvant chemotherapy, HER2-low status was not linked to pathologic complete response (pCR), overall survival (OS), or disease-free survival (DFS) compared to HER2-0 tumors. Factors predicting pCR included nuclear grade III, stage I, invasive ductal carcinoma, lower ER/PR …
