The Association Between The Gnb3 Rs5443 C/C Genotype And Obesity Phenotypes In Taiwanese Individuals, Ling-Yi Xiao, Zi-Lun Lai, Yang-Di Su, Szu-Yun Wang, Nia-Jia Zheng, Po- Ren Hsueh

BioMedicine

Background: The prevalence of obesity has increased significantly over the

years, and its health concerns cannot be underestimated. Obesity not only

causes potential mobility limitations in daily life but also increases the risk of

developing cardiovascular diseases, diabetes, cancer and other health

conditions. While an imbalanced diet and lack of exercise are well-known

causes of obesity, genetic patterns also influence its development. Although the GNB3 gene is known to be involved in lipid metabolism and fat cell

differentiation, studies have shown inconsistent associations between a

common single nucleotide polymorphism of GNB3 (c.825C>T, rs5443) and

obesity across different populations. Therefore, …

Chinese Herbal Medicine Treatment And The Association With Long-Term Major Adverse Cardiac Events In Patients With Chronic Kidney Disease: A Propensity-Score Matched Cohort Study, Yuan-Ching Liao, Mei-Yao Wu, Cheng-Li Lin, Chiz-Tzung Chang, Peter Mayer, Hung-Rong Yen

BioMedicine

Background: Cardiovascular disease (CVD) represents the leading cause of

mortality among idividuals with chronic kidney disease (CKD). While Chinese herbal

medicine (CHM) is commonly used by CKD patients in Taiwan, the impact of CHM

use on cardiovascular outcomes in this population remains insufficiently understood.

Aims: This study aimed to evaluate the association between CHM use and the long-

term risk of major adverse cardiac events (MACEs) in patients with CKD.

Methods: Data were obtained from the Taiwan National Health Insurance Research Database to identify patients aged over 20 years with newly diagnosed CKD. A 1:1 propensity score matching was performed …

Increased Dairy Product Consumption Is Associated With Shorter Telomere Length In Buccal Cells Among Normotensive Adults, Hsin-Hwa Tsai, Yang-Di Su, Zi-Lun Lai, Chia-Yu Lin, Shu-Fan Lin, Hsiu-Ching Hsu, Wen-Yuan Lin, Po-Ren Hsueh

BioMedicine

Background: Telomere length (TL) is a biomarker of biological aging and a predictor of age-related diseases. Dietary patterns, including dairy consumption, may influence telomere dynamics, but the evidence remains limited, particularly in Asian populations. This study investigates the association between dairy consumption and relative telomere length (RTL) in Taiwanese adults, with results analyzed by hypertension status.

Methods: A cross-sectional survey was conducted among 259 adults in Taipei, Taiwan. RTL was measured using quantitative PCR from buccal cells. Dietary intake was assessed through self-reported questionnaires, with a focus on dairy frequency and fat content. Multiple linear regression models were used to …

Mounting evidence is revealing an increasing complexity of gene regulation at the level of messenger RNA (mRNA) translation. Within mammalian cells, canonical cap-dependent mRNA translation depends on the eIF4F complex, consisting of the m7G mRNA cap-binding protein eukaryotic initiation factor 4E (eIF4E), the helicase eIF4A (eIF4A), and the eIF4G (eIF4G1) scaffolding protein. eIF4G1 additionally binds poly(A) binding protein (PABPC1) to facilitate mRNA circularization and nucleates pre-translation initiation complex assembly to initiate ribosomal scanning. In breast epithelial cells, the CELF1 RNA-binding protein specifically promotes the translation of select epithelial-to-mesenchymal transition (EMT) effector mRNAs by binding GU-rich elements (GREs) within their 3' …

Novel Csf Biomarkers For Facilitating Diagnosis Of Cns-Hlh From Other Neuroinflammatory Disorders, Sharat Chandra, Kenneth D Greis, Somchai Chutipongtanate, Nathan Luebbering, Aaron Webster, Kelsey E Poisson, Kristen S Fisher, Kristi Smiley, Rebecca A Marsh, Michael B Jordan, Stella M Davies

Faculty, Staff and Students Publications

Central nervous system (CNS)-hemophagocytic lymphohistiocytosis (HLH) can mimic other neuroinflammatory disorders (ONID), often leading to misdiagnosis. Current diagnostic studies do not reliably distinguish CNS-HLH from ONID. We hypothesized that novel cerebrospinal fluid (CSF) biomarkers identified using unbiased proteomic analysis can facilitate diagnosis of CNS-HLH from ONID. Banked CSF samples were categorized into 3 groups, CNS-HLH, ONID, and controls without CNS inflammation. Proteomic analysis was performed on 25 samples per group (total N = 75). Proteins demonstrating significant changes (>1.5-fold higher and P< .05) in the CNS-HLH compared with ONID and associated with HLH pathophysiology were selected as candidate biomarkers. Cross-platform validation of candidate biomarkers, along with known biomarkers CXCL9 and osteopontin, was performed using enzyme-linked immunosorbent assay (ELISA). One hundred twenty-two proteins were identified on CSF proteomic analysis at 99% confidence. Of these, 10 proteins demonstrated a >1.5-fold change with a P< .05 in CNS-HLH compared with ONID. SerpinG1, lysozyme, and CD14 were selected as candidate biomarkers. ELISA confirmed significant elevation of all 5 biomarkers in CNS-HLH relative to ONID. Median SerpinG1 levels were1242.9 ng/mL in CNS-HLH vs 292.2 ng/mL in ONID (P ≤ .001), lysozyme 222.2 ng/mL vs 65.6 ng/mL (P = .001), and CD14 180.3 ng/mL vs 64.5 ng/mL (P ≤ .001). Median CXCL9 levels were 223.7 ng/mL in CNS-HLH vs 15.5 ng/mL in ONID (P ≤ .001), and osteopontin levels were 356.5 ng/mL vs 92.9 ng/mL (P = .001). These findings demonstrate that novel CSF biomarkers SerpinG1, lysozyme, CD14, and CXCL9 can facilitate diagnosis of CNS-HLH from ONID.

Winner's Curse Free Robust Mendelian Randomization With Summary Data, Zhongming Xie, Wanheng Zhang, Jingshen Wang, Chong Wu

Faculty, Staff and Student Publications

In the past decade, the increased availability of genome-wide association studies summary data has popularized Mendelian Randomization (MR) for conducting causal inference. MR analyses, incorporating genetic variants as instrumental variables, are known for their robustness against reverse causation bias and unmeasured confounders. Nevertheless, classical MR analyses using summary data may still produce biased causal effect estimates due to the winner’s curse and pleiotropy issues. To address these two issues and establish valid causal conclusions, we propose a unified robust Mendelian Randomization framework with summary data, which systematically removes the winner’s curse and screens out invalid genetic instruments with pleiotropic effects. …

Risk Stratification Of Low-Dose Cytarabine And Venetoclax In Patients With Aml Ineligible For Intensive Chemotherapy, Andrew H Wei, Panayiotis Panayiotidis, Pau Montesinos, Kamel Laribi, Vladimir Ivanov, Inho Kim, Jan Novak, Rebecca Champion, Walter Fiedler, Maria Pagoni, Julie Bergeron, Stephen B Ting, Jing-Zhou Hou, Takahiro Yamauchi, Jianxiang Wang, Stephen A Strickland, Michael R Savona, Tara L Lin, Anoop Enjeti, Ing Soo Tiong, Sangmin Lee, Gail J Roboz, Relja Popovic, Qi Jiang, Zihuan Liu, Yan Sun, Wellington Mendes, Brenda Chyla, Courtney D Dinardo

Prognostic risk categorization aids treatment selection for patients with acute myeloid leukemia (AML). Although the European LeukemiaNet (ELN) classifications (2017 and 2022) for AML have been used to stratify outcomes for patients receiving intensive chemotherapy, their application to patients receiving less intensive therapy, such as azacitidine plus venetoclax, has been less satisfactory. In response, a 4-gene classifier that stratifies older patients with AML unfit for intensive chemotherapy into those with higher benefit (wild type), intermediate benefit (FLT3-internal tandem duplication [ITD] or NRAS/KRAS mutation), or lower benefit (TP53 mutation) after azacitidine plus venetoclax treatment was developed. We hypothesized that this 4-gene …

Exonuclease/endonuclease/phosphatase (EEP)-fold hydrolases are canonically monomeric phosphodiesterases exemplified by APE1, DNase I, and TDP2 nucleases. While EEP family domain containing protein 1 (EEPD1) acts in DNA stress responses, its proposed nuclease activities are enigmatic. Here, we integrate hybrid structural methods, evolution, biochemistry, cancer genomics, plus molecular and cell biology to define EEPD1 structure, assembly, and function at stalled DNA replication forks. Results imply EEPD1 surprisingly requires both unique EEP domain dimer and distinctive tandem Helix-hairpin-Helix [(HhH)2] domains to clamp double-stranded (ds) DNA at reversed DNA replication forks for fork protection. Small-angle X-ray Scattering (SAXS), crystal, and cryo-EM structures unveil an …

The Path Forward For T Cell Engagers In Patients With Prostate Cancer, Sumit K. Subudhi, Bilal A. Siddiqui, Kevin K. Zarrabi, William K. Kelly, Charles G. Drake

Department of Medical Oncology Faculty Papers

T cell engagers (TCEs) recruit T cells to the tumor microenvironment (TME) to induce antitumor immune responses. TCEs have demonstrated promising clinical responses in patients with metastatic castration-resistant prostate cancer and have advanced into phase 3 clinical trials. Here we provide an overview of the mechanisms of action of TCEs, including both CD3-targeted and CD28-targeted agents, and review the clinical development of these agents for prostate cancer. We propose a path forward for TCEs in prostate cancer, in which innovative clinical trials will facilitate a biological understanding of mechanisms of efficacy and toxicity to inform: (1) development of predictive biomarkers …

SUPT16H encodes a subunit of the FACT (FAcilitates Chromatin Transcription) complex, a histone chaperone essential for maintaining chromatin integrity during transcription, replication, and DNA repair. Pathogenic de novo SUPT16H missense variants have previously been linked to neurodevelopmental disorders in eight individuals. Here, we expand the genotypic and phenotypic spectrum by identifying 24 additional individuals harboring ultrarare heterozygous missense or truncating variants, who share overlapping clinical features including intellectual disability, autism spectrum disorder, hypotonia, and characteristic craniofacial dysmorphism. To elucidate the underlying mechanisms, we generated a supt16h knockout zebrafish model using CRISPR/Cas9. The supt16h loss-of-function (LOF) model recapitulated key patient phenotypes …

Direct Synthesis Of Bicyclo[1.1.1]Pentane (Bcp) Boronates From Carboxylic Acids, Yongchen Wang, Jess C Tang, Gang Wu, Julian G West

Faculty, Staff and Student Publications

Bicyclo[1.1.1]pentane (BCP) boronic esters are crucial intermediates for accessing BCP-containing drugs with improved pharmacokinetic profiles, yet their synthesis typically relies on pre-formed redox-active esters derived from carboxylic acids. Here we report a general, single-step method for the direct conversion of carboxylic acids into BCP boronic esters. Upon irradiation of carboxylic acids with [1.1.1]propellane and bis(pinacolato)diboron (B2pin2) in dimethyl sulfoxide (DMSO), BCP boronates are obtained in good yields, which are further enhanced by the addition of an iron catalyst. Mechanistic studies suggest that photolytic cleavage of a B2pin2–DMSO complex initiates decarboxylation via hydrogen atom transfer (HAT), while iron catalysis enables a …

Gradual reduction of cerebral blood flow occurs with aging, and it is a major cause of vascular dementia, a group of dementias with a cerebrovascular component. Interestingly, patients who have suffered a vascular insult may develop retinopathy, which may occur as an early symptom of vascular dementia. Several rodent models using young animals have been generated to mimic retinopathy caused by cerebral hypoperfusion; however, given that aging is an important factor in developing vascular dementia and hypoperfusion retinopathy, we propose to use aged (17-month-old) mice in a model of cerebral hypoperfusion. In this model, we implant two metallic micro-coils (0.16 …

Lung cancer remains the leading cause of cancer-related deaths worldwide, partly because many patients are diagnosed at late stages, highlighting the urgent need for effective early detection and intervention strategies. Low-dose computed tomography (LDCT)-based screening reduces lung cancer mortality in high-risk populations defined by age and smoking history; however, the uptake of LDCT remains low among eligible individuals. Compounding this issue, modelling studies estimate that nearly half of lung cancers occur in individuals who do not meet eligibility criteria for LDCT-based lung cancer screening under current guidelines. Moreover, LDCT-based screening has inherent limitations, including a high rate of false-positive results …

Advances In Hpv Vaccination In People Living With Hiv: A Review, Megan Mooberry, J Brooks Jackson, Mary B Rysavy

Faculty, Staff and Student Publications

Human papillomavirus (HPV) is the most common sexually transmitted infection worldwide and is a leading cause of cervical, anal, penile, and oropharyngeal cancers. This review summarizes the epidemiology of HPV and the immunogenicity, clinical efficacy, and current HPV vaccination recommendations among people living with HIV (PLWH). PLWH experience a disproportionate burden of HPV-related infection and HPV-related malignancies. Although HPV vaccines have been shown to be highly effective, vaccination coverage among PLWH remains suboptimal, particularly in low- and middle-income countries. Barriers to vaccination include extended dosing schedules, limited awareness of the vaccine, and misinformation. Evidence indicates HPV vaccines are safe and …

Steroid Receptor Coactivators - From Basic Research To Translational Opportunities, Yosef Gilad, Sang Jun Han, David M Lonard

Faculty, Staff and Students Publications

The concept of nuclear receptor (NR) coregulation was proposed nearly two decades before it was experimentally validated. According to this model, NRs - executors of a vast array of transcriptional programs - do not act independently but are governed by a network of regulatory proteins that either activate or repress their biological function. NRs identify the genes to be regulated. However, coregulators ultimately serve as the true controllers of transcriptional outcomes. They recruit cofactors and coordinate the activity of transcriptional complexes, thereby shaping NR-mediated gene expression beyond NRs' intrinsic functionality. The Steroid Receptor Coactivator (SRC) family is the most extensively …

Efficient DNA double-strand break (DSB) repair by homologous recombination (HR), as initiated by BRCA1 recruitment orchestrated by histone and non-histone proteins, is critical to genome stability, replication, transcription, and cancer avoidance. Here we reveal Heterochromatin Protein1 beta (HP1β) promotes BRCA1 enrichment at DNA DSB sites in gene-rich regions, and this is impaired by HP1β depletion. We find that HP1β is specifically enriched at DSBs within gene-rich regions via its Chromo Shadow Domain (CSD) that interacts with both Chromatin Assembly Factor 1 and the RING1A ubiquitinase component of Polycomb Repressor Complex 1. The resulting protein complex facilitates BRCA1 recruitment by promoting …
