Obsessive-compulsive disorder (OCD) affects ~1% of children and adults and is partly caused by genetic factors. We conducted a genome-wide association study (GWAS) meta-analysis combining 53,660 OCD cases and 2,044,417 controls and identified 30 independent genome-wide significant loci. Gene-based approaches identified 249 potential effector genes for OCD, with 25 of these classified as the most likely causal candidates, including WDR6, DALRD3 and CTNND1 and multiple genes in the major histocompatibility complex (MHC) region. We estimated that ~11,500 genetic variants explained 90% of OCD genetic heritability. OCD genetic risk was associated with excitatory neurons in the hippocampus and the cortex, along …

Preimplantation genetic testing for polygenic disorders (PGT-P) has been commercially available since 2019. PGT-P makes use of polygenic risk scores for conditions which are multifactorial and are significantly influenced by environmental and lifestyle factors. If current predictions are accurate, then absolute risk reductions range from about 0.02% to 10.1%, meaning that between 10 and 5,000 in vitro fertilization patients would need to be tested with PGT-P to prevent one offspring from becoming affected in the future, depending on the condition and the number of embryos available. Survey and interview data reveal that patients and the public have largely favorable views …

Irnet: Immunotherapy Response Prediction Using Pathway Knowledge-Informed Graph Neural Network, Yuexu Jiang, Manish Sridhar Immadia, Duolin Wang, Shuai Zeng, Yen On Chan, Jing Zhou, Dong Xu, Trupti Joshi

Biomedical Sciences

Introduction: Immune checkpoint inhibitors (ICIs) are potent and precise therapies for various cancer types, significantly improving survival rates in patients who respond positively to them. However, only a minority of patients benefit from ICI treatments.

Objectives: Identifying ICI responders before treatment could greatly conserve medical resources, minimize potential drug side effects, and expedite the search for alternative therapies. Our goal is to introduce a novel deep-learning method to predict ICI treatment responses in cancer patients.

Methods: The proposed deep-learning framework leverages graph neural network and biological pathway knowledge. We trained and tested our method using ICI-treated patients’ data from several …

The origins of immunosuppression, neutropenia, and anemia in patients with chronic lymphocytic leukemia (CLL) are not fully understood. Because in patients with CLL, circulating exosomes, which participate in cell-to-cell interactions, are CLL cell-derived, we examined whether those exosomes contribute to abnormal features of this disease. Our data revealed that CLL cell-derived exosomes engulfed by healthy donors’ monocytes, fibrocytes, and lymphocytes altered target-cell gene and protein expression and suppressed normal hematopoiesis. CLL cell-derived exosomes increased normal monocytes’ CD14 and CD16 expression such that it mimicked the accessory cell profile and upregulated T cells’ checkpoint PD-1 and CD160 protein levels, potentially reducing …

While monoclonal antibody-based targeted therapies have substantially improved progression-free survival in cancer patients, the variability in individual responses poses a significant challenge in patient care. Therefore, identifying cancer subtypes and their associated biomarkers is required for assigning effective treatment. In this study, we integrated genotype and pre-treatment tissue RNA-seq data and identified biomarkers causally associated with the overall survival (OS) of colorectal cancer (CRC) patients treated with either cetuximab or bevacizumab. We performed enrichment analysis for specific consensus molecular subtypes (CMS) of CRC and evaluated differential expression of identified genes using paired tumor and normal tissue from an external cohort. …

Despite the fact that human adenovirus (HAdV) causes severe infections in immunosuppressed and immunocompetent individuals, especially in children, there is currently no specific treatment for these infections. Previously we reported a new salicylamide analogue, JMX0312, as a potent inhibitor of HAdV infection with low cytotoxicity in vitro. Here we evaluate the in vivo efficacy and safety of this molecule in the immunosuppressed Syrian hamster model of HAdV infection. JMX0312 administration at a dose of 6.25 mg/kg did not affect the body weight of the animals, and reduced the viral load in liver and blood in a similar way than cidofovir. …

Thoracic tumours represent a significant proportion of malignant cancers. While radiotherapy (RT) improves prognosis, it can also lead to side effects such as radiation-induced pneumonitis (RP). Since SIRT6 is involved in DNA repair, energy metabolism and inflammation, this study aims to investigate the expression of SIRT6 in lymphocytes as a potential biomarker and therapeutic target for RP. This study included 170 patients diagnosed with thoracic tumours, all of whom underwent thoracic RT. RP was evaluated and classified as severe RP (SRP) and lower as non-severe RP (NSRP). Analyses were performed using SPSS version 26.0 and the R. Among 170 patients …

Purpose: Osteoradionecrosis of the jaw (ORNJ) is a severe iatrogenic disease characterized by bone death after radiation therapy to the head and neck. With >9 published definitions and at least 16 classification systems, the true incidence and severity of ORNJ are obscured by lack of a standard for disease definition and severity assessment, leading to inaccurate estimation of incidence, reporting ambiguity, and likely underdiagnosis worldwide. This study aimed to achieve consensus on an explicit definition and phenotype of ORNJ and related precursor states through data standardization to facilitate effective diagnosis, monitoring, and multidisciplinary management of ORNJ.

Each session was 30 min, with active stimulation at 2 mA and sham at 0 mA, incorporating brief ramp-up and ramp-down phased. Following the 10-week RCT, all participants were …

Emerging Technologies Of Single-Cell Multi-Omics, Yi June Kim, Koichi Takahashi

Faculty, Staff and Student Publications

The heterogeneity of the hematopoietic system was largely veiled by traditional bulk sequencing methods, which measure the averaged signals from mixed cellular populations. In contrast, single-cell sequencing has enabled the direct measurement of individual signals from each cell, significantly enhancing our ability to unveil such heterogeneity. Building on these advances, numerous single-cell multi-omics techniques have been developed into high-throughput, routinely accessible platforms, delineating the precise relationships among different layers of the central dogma in molecular biology. These technologies have uncovered the intricate landscape of genetic clonality and transcriptional heterogeneity in both normal and malignant hematopoietic systems, highlighting their roles in …

Encoding 3d Information In 2d Feature Maps For Brain Ct-Angiography, Uma M Lal-Trehan Estrada, Sunil Sheth, Arnau Oliver, Xavier Lladó, Luca Giancardo

Faculty, Staff and Student Publications

We propose learnable 3D pooling (L3P), a CNN module designed to compress 3D information into 2D feature maps using anisotropic convolutions and unidirectional max pooling. Specifically, we used L3P followed by a 2D network to generate predictions from 3D brain CT-Angiography (CTA) in the context of large vessel occlusion (LVO). To further demonstrate its versatility, we extended its application to 3D brain MRI analysis for brain age prediction. First, we designed an experiment to classify the LVO-affected hemisphere (left or right), projecting the input CTA into the sagittal plane, which allowed to assess the ability of L3P to encode the …

Multicancer Early Detection Tests At A Crossroads: Commercial Availability Ahead Of Definitive Evidence, Carmen E Guerra, Jennifer Keating Litton, Carolina E Viswanath, A Mark Fendrick

Faculty, Staff and Student Publications

Multicancer early detection tests (MCEDs), sometimes referred to as liquid biopsies, are tests that can screen for multiple cancers by analyzing blood, urine, and other bodily fluids for biomarkers released by cancer cells. These tests have the potential to change the cancer screening paradigm if they are shown to reduce cancer mortality. However, it is not yet known whether MCEDs reduce mortality. Randomized controlled trials, the gold standard for evaluating cancer screening programs, are currently evaluating the effectiveness of MCEDs. However, because cancer-specific and all-cause mortality are end points that can take years to reach, trials are being designed with …
