The DAVID Gene Functional Classification Tool http://david.abcc.ncifcrf.gov uses a novel agglomeration algorithm to condense a list of genes or associated biological terms into organized classes of related genes or biology, called biological modules. This organization is accomplished by mining the complex biological co-occurrences found in multiple sources of functional annotation. It is a powerful method to group functionally related genes and terms into a manageable number of biological modules for efficient interpretation of gene lists in a network context.

Background: Hereditary transthyretin (ATTRv) amyloidosis is a rare, adult-onset autosomal-dominant disorder caused by pathogenic variants in the transthyretin (TTR) gene. Data about relevant variants in specific populations and typical initial manifestations may facilitate early diagnosis and treatment. We here describe the genetic landscape of ATTRv amyloidosis in Israel.

Background: Primary hyperoxaluria type 1 (PH1) is an autosomal recessive disorder with dysregulated glyoxylate metabolism in the liver. Oxalate over-production leads to renal stones, progressive kidney damage and renal failure, with potentially life-threatening systemic oxalosis. Nedosiran is a synthetic RNA interference therapy, designed to reduce hepatic lactate dehydrogenase (LDH) to decrease oxalate burden in PH.

Bioinformatics Analysis of Programmed Death-1-Trastuzumab Resistance Regulatory Networks in Breast Cancer Cells.

Asian Pac J Cancer Prev

January 2025

Cancer Chemoprevention Research Center, Faculty of Pharmacy, Universitas Gadjah Mada Sekip Utara II, 55281 Yogyakarta, Indonesia.

Objective: Programmed cell death-1 (PD-1, encoded by PDCD1) regulatory network participates in glioblastoma multiforme development. However, such a network in trastuzumab-resistant human epidermal growth factor receptor 2-positive (HER2+) breast cancer remains to be determined. Accordingly, this study was aimed to explore the PD-1 regulatory network responsible for the resistance of breast cancer cells to trastuzumab through a bioinformatics approach.

Introduction: Alterations in multiple subregions of the human prefrontal cortex (PFC) have been heavily implicated in psychiatric diseases. Moreover, emerging evidence suggests that circadian rhythms in gene expression are present across the brain, including in the PFC, and that these rhythms are altered in disease. However, investigation into the potential circadian mechanisms underlying these diseases in animal models must contend with the fact that the human PFC is highly evolved and specialized relative to that of rodents.

Racial Disparities in Time to Huntington Disease Diagnosis in North America: An ENROLL-HD Analysis.

Neurol Clin Pract

October 2024

Department of Neurology (AM, YB, SLP), David Geffen School of Medicine; Institute for Society and Genetics (AM); Interdepartmental Undergraduate Neuroscience Program (AM), UCLA; Division of General Internal Medicine (ACO), Department of Medicine, University of Colorado Anschutz Medical Campus, Aurora, CO; Department of Neurology (YB), Cedars Sinai Health Center, Los Angeles, CA; and Division of General Internal Medicine and Health Services Research (AB), Department of Medicine, David Geffen School of Medicine, UCLA.

Background And Objectives: There are well-documented racial and ethnic disparities in access to neurologic care and disease-specific outcomes. Although contemporary clinical and neurogenetic understanding of Huntington disease (HD) is thanks to a decades-long study of a Venezuelan cohort, there are a limited number of studies that have evaluated racial and ethnic disparities in HD. The goal of this study was to evaluate disparities in time from symptom onset to time of diagnosis of HD.
