Histone post-translational modifications (PTMs) are crucial to eukaryotic genome regulation, with a range of reported functions and mechanisms of action. Though often studied individually, it has long been recognized that the modifications function by combinatorial synergy or antagonism. Interplay may involve PTMs on the same histone, within the same nucleosome (containing a histone octamer), or between nucleosomes in higher-order chromatin. Given this, the field must distinguish ever greater complexity, and the context in which it is studied, with brevity and precision. The proteoform was introduced to define individual forms of a protein by sequence and PTMs, followed by the nucleoform …

Faculty, Staff and Students Publications

Tumor associated macrophages (TAMs) directly contribute to the dismal prognosis of glioblastoma by preventing anti-tumor immunity and promoting tumor invasion and angiogenesis. Inhibiting TAM infiltration is a potential therapeutic strategy in glioblastoma, with several chemokine antagonists in early clinical development. Hydrogen sulfide, a gasotransmitter that regulates microglial accumulation in a wide range of CNS diseases, may be a novel therapeutic target to prevent TAM recruitment in glioblastoma. In this study, hydrogen sulfide concentrations were directly measured from 14 isocitrate dehydrogenase (IDH)-wildtype glioblastoma surgical samples and compared against overall survival as well as expression of TAM markers and chemokines. Effects of …

Neck Pain In Migraine: A Narrative Review And Steps To Correct Evaluation And Treatment, Tayla A. Rees, Diana Doukhi, Victor S. Wang, Anita Balcerbula, Michelle Bravo, Haniyeh Fathi, Bahtigul Holmuratova, Michalis Kodounis, Seblewongel A. Seyoum, Semih Tasdelen, Hasmik Vekilyan, Edoardo Caronna, Patricia Pozo-Rosich

Department of Neurology Faculty Papers

Background: Neck pain is common in migraine patients, occurring during all migraine phases and between attacks. It can be a migraine symptom, trigger or a coexisting condition, and is associated with greater disability and poorer treatment response. There is evidence that neck pain associated with headaches can be frequently incorrectly diagnosed as a cervical disorder rather than migraine, resulting in a lack of appropriate treatment. Accurately assessing the connection between neck pain and migraine is crucial for effective treatment. Methods: This narrative review aims to summarise existing research on the role and contribution of neck pain in migraine, both as …

Children’s Nutrition Research Center Staff Publications

Aim: To assess the risk for impaired insulin homeostasis as a function of menopause-related factors and gut microbiota dysbiosis in non-diabetic, post-menopausal women.

Materials and methods: Baseline data (n = 175 women) from the Microbiome and Insulin Longitudinal Evaluation Study (MILES) were used, including insulin and dysglycaemia indices calculated from a 2-h oral glucose tolerance test, untargeted peripheral metabolomics, targeted peripheral short chain fatty-acid levels and faecal bacterial microbiota surveyed by whole-metagenomic sequencing.

Results: After adjustment for covariates, menopause age < 50 years and use of hormone replacement therapy (HRT) were associated with lower Matsuda et al. insulin sensitivity index levels (β = -0.232, confidence interval (CI) = [-0.450, -0.014] and β = -0.275, CI = [-0.444, -0.107], respectively) but not pre-menopausal gynaecologic surgery. Pre-menopausal gynaecologic surgery was significantly associated with faecal microbiota beta diversity driven by a relative increase in diabetogenic Ruminococcus gnavus and Clostridium species and a decrease in protective Alistipes species and Akkermansia muciniphila relative abundances. A reduction in two glycerophospholipids in the plasmalogen class significantly statistically mediated an inverse association between gynaecologic surgery before menopause and insulin sensitivity.

Conclusions: Menopause age and history of HRT are more strongly associated with insulin resistance than gynaecologic surgery before menopause. However, …

Three-Dimensional Human Mucopolysaccharidosis Iva Chondrocyte Culture Reveals Significant Impairments In The Lysosomal-Mitochondrial Crosstalk, Andrés Felipe Leal, Sampurna Saikia, Shaukat A. Khan, Shunji Tomatsu

Department of Pediatrics Faculty Papers

Mucopolysaccharidosis IVA (MPS IVA) is a lysosomal storage disorder (LSD) caused by a deficiency of N-acetylgalactosamine-6-sulfate sulfatase enzyme. MPS IVA patients suffer from skeletal dysplasia due to the abnormal function of chondrocytes. Given the interactions of lysosomes with various intracellular organelles, it is not surprising that lysosomal dysfunction can lead to improper functioning of lysosome-interacting organelles such as mitochondria. Mitochondrial alterations have been evaluated in several LSDs; nevertheless, they have not been fully addressed in MPS IVA. In this study, we assessed the mitochondrial alterations in MPS IVA chondrocytes using a three-dimensional culture approach. Our findings revealed that MPS IVA …

Recapitulating The Immune Microenvironment In Pediatric Brain Cancer: Preclinical Modeling Strategies., Adip G. Bhargav, Joseph S. Domino, David Akhavan, Jo Ling Goh

Manuscripts, Articles, Book Chapters and Other Papers

Primary brain and CNS tumors comprise the most common tumors in children and are the most common cause of cancer deaths in this population. Pediatric primary malignant brain tumors including high-grade glioma and medulloblastoma account for a significant proportion of these cancer deaths. Advances in the surgical management and adjuvant treatment paradigms have improved the prognosis of many patients with these tumors, but there remains a subset of treatment-resistant tumors or tumors with unique genetics aberrations and aggressive phenotypes that confer a poor prognosis. Immunotherapeutic strategies have demonstrated promise in pre-clinical studies and early clinical trials. However, high-fidelity evaluation of …

Isoform-Level Analyses Of 6 Cancers Uncover Extensive Genetic Risk Mechanisms Undetected At The Gene-Level, Yung-Han Chang, Sean T Bresnahan, S Taylor Head, Tabitha A Harrison, Yao Yu, Chad D Huff, Bogdan Pasaniuc, Sara Lindström, Arjun Bhattacharya

Faculty, Staff and Student Publications

Background: Integrating genome-wide association study (GWAS) and transcriptomic datasets can identify mediators for genetic risk of cancer. Traditional methods often are insufficient as they rely on total gene expression measures and overlook alternative splicing, which generates different transcript-isoforms with potentially distinct effects.

Methods: We integrate multi-tissue isoform expression data from the Genotype Tissue-Expression Project with GWAS summary statistics (all N > ~20,000 cases) to identify isoform- and gene-level associations with six cancers (breast, endometrial, colorectal, lung, ovarian, prostate) and six related cancer subtype classifications (N = 12 total).

Results: Directly modeling isoforms using transcriptome-wide association studies (isoTWAS) significantly improves discovery of …

Faculty, Staff and Student Publications

Adult-type granulosa cell tumors (AGCT) are rare ovarian tumors with few effective treatments for recurrent disease. To elucidate spatial features and cellular interactions within the AGCT tumor microenvironment, we applied imaging mass cytometry using a 34-marker panel on 130 regions from 24 AGCT samples, profiling more than 900,000 single cells. Analysis confirmed the immune “cold” phenotype of AGCTs and showed higher macrophage abundance in recurrent compared with primary tumors. We observed substantial heterogeneity in tissue architecture across samples, including variable presence of FOXL2+ cells embedded in collagen-rich regions (FOXL2+COL1A1+ cells). Based on tumor microenvironment composition, we defined two AGCT subtypes: …

Transfer Learning Via Distributed Brain Recordings Enables Reliable Speech Decoding, Aditya Singh, Tessy Thomas, Jinlong Li, Greg Hickok, Xaq Pitkow, Nitin Tandon

Faculty, Staff and Student Publications

Speech brain-computer interfaces (BCIs) combine neural recordings with large language models to achieve real-time intelligible speech. However, these decoders rely on dense, intact cortical coverage and are challenging to scale across individuals with heterogeneous brain organization. To derive scalable transfer learning strategies for neural speech decoding, we used minimally invasive stereo-electroencephalography recordings in a large cohort performing a demanding speech motor task. A sequence-to-sequence model enabled decoding of variable-length phonemic sequences prior to and during articulation. This enabled development of a cross-subject transfer learning framework to isolate shared latent manifolds while enabling individual model initialization. The group-derived decoder significantly outperformed …
