Background: Hodgkin lymphoma has excellent survival rates in adolescents and young adults (AYA, diagnosed between ages 15 and 39 years). However, survivors are at risk of treatment-related late effects. Whereas radiotherapy (RT) de-escalation/omission has emerged as an approach to minimize late effects, no prior studies have evaluated RT use over time in AYAs with Hodgkin lymphoma.

Methods: Using the National Cancer Database, we identified 40,717 AYAs diagnosed with Hodgkin lymphoma between 2004 and 2020. Differences in sociodemographic and clinical variables were assessed using a two-sample two-sided t test or χ2 test. RT use was summarized per year by frequency with …

Targeting Aldh16a1 Mediated Thioredoxin Lysosomal Degradation To Enhance Ferroptosis Susceptibility In Smarca4-Deficient Nsclc, Guoshu Bi, Jiaqi Liang, Yunyi Bian, Guangyao Shan, Shencheng Ren, Haochun Shi, Xiaolong Huang, Junkan Zhu, Qun Wang, Wei Jiang, Boyi Gan, Cheng Zhan

Faculty, Staff and Student Publications

Ferroptosis, an iron-dependent form of cell death, holds promise for cancer therapy. However, the intricate link between ferroptosis and oncogenic mutations remains unclear. Here we show that SMARCA4, a well-established tumour suppressor whose deficiency is associated with poor prognosis and resistance to treatments, sensitizes non-small cell lung cancer (NSCLC) cells to ferroptosis. Mechanistically, SMARCA4 promotes chromatin accessibility and expression of ALDH16A1. Surprisingly, ALDH16A1 lacks ALDH enzymatic activity, but binds to the anti-ferroptotic oxidoreductase thioredoxin (TXN), facilitating its translocation to the lysosome and subsequent degradation. Meanwhile, ALDH16A1 directly inhibits TXN's oxidoreductase function by occluding its active site. We also show that …

Immunosuppressive myeloid cells are important in a variety of physiological and pathological contexts, including tumor development, but how hormones might regulate their activity is unclear. Secretogranins, a family of secretory proteins in endocrine and neuronal cells, are proposed to function as prohormones or hormones, but their specific receptors are unknown. Here we show that secretogranin 2 (SCG2), a granin family member, functionally interacts with leukocyte immunoglobulin-like receptor B4 (LILRB4) on monocytic cells. Tumor-derived SCG2 promotes tumor growth in myeloid-specific LILRB4 transgenic mice in a T cell-dependent manner, whereas SCG2 deficiency in host mice impairs tumor progression and reduces infiltration of …

Computational Analysis Of Dna Methylation From Long-Read Sequencing, Yilei Fu, Winston Timp, Fritz J Sedlazeck

Faculty, Staff and Students Publications

DNA methylation is a critical epigenetic mechanism in numerous biological processes, including gene regulation, development, ageing and the onset of various diseases such as cancer. Studies of methylation are increasingly using single-molecule long-read sequencing technologies to simultaneously measure epigenetic states such as DNA methylation with genomic variation. These long-read data sets have spurred the continuous development of advanced computational methods to gain insights into the roles of methylation in regulating chromatin structure and gene regulation. In this Review, we discuss the computational methods for calling methylation signals, contrasting methylation between samples, analysing cell-type diversity and gaining additional genomic insights, and …

The mammalian kidney contains numerous nephrons connected to the collecting ducts, and each nephron consists of a glomerulus, a proximal tubule, the loop of Henle (LoH), and a distal tubule. Folliculin (FLCN) is a causative gene for Birt-Hogg-Dubé syndrome, which is characterized by a variety of manifestations, including renal cysts and cancer. Although deletion of Flcn in the mouse collecting duct and distal nephron leads to cyst formation, its precise role in the entire nephron remains unclear. Herein, nephron-specific Flcn knockout mice exhibited cystogenesis along the entire nephron segments, most prominent in the LoH, preceded by an irregularly shaped lumen …

Current Controversies In Prenatal Diagnosis 2: Conventional Postmortem Examination Remains The Gold Standard For The Anatomical Examination Of Fetal Loss, J Ciaran Hutchinson, Lorraine Potocki, Ignatia B Van Den Veyver

Duncan NRI Faculty and Staff Publications

A comprehensive postmortem examination is an essential component of a work-up after stillbirth. Its findings can support accurate counseling of parents about causes and risk of recurrence. It also supports providers' decisions about most appropriate testing and management plans for future pregnancy to prevent recurrence. Informing parents about fetal autopsy and obtaining their consent is challenging, and conducting a fetal autopsy requires expertise that is, not universally available. Newer non-invasive or minimally invasive methods such as postmortem MRI and targeted biopsies can replace or supplement autopsies, but one must recognize that expertise in these methods is likewise not broadly available. …

Duncan NRI Faculty and Staff Publications

The evolution of prenatal genetic testing has transformed prenatal diagnosis into a more precise and individualized approach. Advanced tools such as chromosomal microarray analysis and exome sequencing have enabled the prenatal diagnosis of more genetic conditions, including anomalies and disorders eligible for fetal therapy. When in utero therapy is considered, accurate genetic diagnosis is essential for guiding providers' and patients' decisions regarding management and outcomes. This chapter reviews available prenatal genetic screens and tests, their indications, and counseling strategies. It also explores genetic abnormalities associated with fetal structural anomalies and their implications for decision-making in fetal interventions.

Decreased brain levels of coenzyme Q10 (CoQ10), an endogenously synthesized lipophilic antioxidant1,2, underpin encephalopathy in primary CoQ10 deficiencies3,4 and are associated with common neurodegenerative diseases and the ageing process5,6. CoQ10 supplementation does not increase CoQ10 pools in the brain or in other tissues. The recent discovery of the mammalian CoQ10 headgroup synthesis pathway, in which 4-hydroxyphenylpyruvate dioxygenase-like protein (HPDL) makes 4-hydroxymandelate (4-HMA) to synthesize the CoQ10 headgroup precursor 4-hydroxybenzoate (4-HB)7, offers an opportunity to pharmacologically restore CoQ10 synthesis and mechanistically treat CoQ10 deficiencies. To test whether 4-HMA …

Developmental domains, such as cognitive, language, and motor, are key concepts of interest in longitudinal studies of intellectual and developmental disabilities (IDD). Normative scores (e.g., IQ) are often used to operationalize performance on standardized tests of these concepts, but it is the interval-distributed person-ability scores that are intended for the assessment of within-individual change. Here we illustrate the use and interpretation of several Stanford Binet, 5th Edition score types (IQ, extended IQ, Z-normalized raw score, developmental quotient, raw sum score, age equivalent, and ability score) using data from two longitudinal studies of rare genetic conditions associated with IDD. We found …

Recent studies have highlighted the pivotal role of the cGAS‐STING pathway in cancer immunotherapy. However, clinical trials with cGAS‐STING pathway agonists have faced setbacks thanks to their short biological half‐life, lack of tumor specificity, and potential to promote tumor immune evasion. To address these challenges, a novel exosome‐based drug delivery platform, termed cmExoaCD11b is developed, designed to precisely target and reprogram the tumor microenvironment (TME) in situ for pancreatic cancer immunotherapy. cmExoaCD11b is engineered to encapsulate high copy numbers of IL‐12 mRNA and 2′3’‐cGAMP (cGAMP) and is functionalized with CD11b antibodies for targeted delivery to macrophages. Notably, cmExoaCD11b facilitated the …

Polydrug Abuse: Choice Between Drugs As A Function Of Concurrent Nonindependent Ratio Sizes, Richard A Meisch, Thomas H Gomez, Scott D Lane

Faculty, Staff and Student Publications

Polydrug abuse is the persistent self-administration of more than one reinforcing drug. The present study provided rhesus monkeys concurrent access to two drugs: 8% alcohol and solutions of either cocaine or methadone. The liquids were available under concurrent nonindependent fixed-ratio (FR) schedules across increasing and then decreasing ratio sizes. These schedules generate high rates of changeover responses and yield a dependent variable of responses per delivery that is not rigidly tied to the ratio-schedule value. The programmed schedule size was equal for both liquids and increased in the sequence 8, 16, 32, and so on until responding decreased, whereupon the …

Aberrant DNA methylation has been described in nearly all human cancers, yet its interplay with genomic alterations during tumor evolution is poorly understood. To explore this, we performed reduced representation bisulfite sequencing on 217 tumor and matched normal regions from 59 patients with non-small cell lung cancer from the TRACERx study to deconvolve tumor methylation. We developed two metrics for integrative evolutionary analysis with DNA and RNA sequencing data. Intratumoral methylation distance quantifies intratumor DNA methylation heterogeneity. MR/MN classifies genes based on the rate of hypermethylation at regulatory (MR) versus nonregulatory (MN) CpGs to identify driver genes exhibiting recurrent functional …

Lymph node metastasis (LNM) is a critical prognostic factor for patients with oral squamous cell carcinoma (OSCC). Previous research has implicated the partial epithelial-to-mesenchymal transition of tumor cells and myofibroblastic cancer-associated fibroblasts (myCAFs) in the LNM process. However, the underlying molecular mechanisms remain poorly understood. Here, we conducted a comprehensive molecular analysis integrating original and publicly available OSCC data from bulk genome and transcriptome, single-cell transcriptome, and spatial transcriptome analyses. We found that myCAFs were quantitatively and functionally activated in LNM-positive samples and spatially colocalized with OSCC cells within the invasive tumor front (ITF), providing a niche that may facilitate …

Peripartum Depression Pharmacotherapies Targeting Gaba-Glutamate Neurotransmission, Alan C Courtes, Louisa Smitherman, Lokesh Shahani, Jair C Soares, Laura Goetzl, Rodrigo Machado-Vieira

Faculty, Staff and Student Publications

Peripartum depression (PPD) represents a significant public health concern, affecting 10-17% of women globally. Traditional monoaminergic treatments demonstrate limited efficacy and delayed onset of action. The glutamate-GABA imbalance hypothesis provides a novel theoretical framework for understanding depression pathophysiology and developing targeted therapeutic interventions. This review examines emerging pharmacotherapeutic approaches targeting glutamatergic and GABAergic neurotransmitter systems for PPD treatment. Search criteria targeted randomized clinical trials investigating GABA-A-positive allosteric modulators (brexanolone, zuranolone, and ganaxolone) and NMDA receptor antagonists (ketamine and esketamine) in PPD patients. Brexanolone was the first neurosteroid to receive FDA approval for PPD, while zuranolone also shows promise. Ketamine and …

Nonsyndromic orofacial clefts (OFCs) are common, heritable birth defects caused by both genetic and environmental risk factors. Despite the identification of many genetic loci harboring OFC-risk variants, there are many unknown genetic determinants of OFC. Furthermore, while the process of embryonic facial development is well characterized, the molecular mechanisms that underly it are not. This represents a major hurdle in understanding how disruptions in these biological processes result in OFC. Thus, we sought to identify novel OFC-risk loci through a genome-wide multi-ancestry study of five nested OFC phenotypes (isolated cleft lip [CLO], isolated cleft palate [CPO], cleft lip and palate …
