Identifying Gene Predictors of Chemicals Linked With Breast Cancer: A Machine Learning Analysis of MCF7 Cellular Transcriptomic Screening Data

open access: yesEnvironmental and Molecular Mutagenesis, Volume 66, Issue 8, Page 425-441, October 2025.
ABSTRACT Breast cancer is the most prevalent cancer in women and has been linked to exposure to environmental chemicals. However, many chemicals have not been evaluated for relationships with this outcome. In this study, we analyzed RNA sequencing data from human breast cancer‐derived MCF7 cells exposed to hundreds of individual chemicals.

Metabolic factors determining the effectiveness of hypouricemic treatment of gouty arthritis

open access: yesBolʹ, Sustavy, Pozvonočnik, 2018
Background. The treatment of some forms of arti­cular pathology with gout remains insufficiently effective, and often it’s impossible to achieve normal indicators of uricemia on the background of uric acid-normalizing medicines.

A Patient‐Derived 3D Cyst Model of Polycystic Kidney Disease That Mimics Disease Development and Responds to Repurposing Candidates

open access: yesClinical and Translational Science, Volume 18, Issue 4, April 2025.
ABSTRACT Autosomal dominant polycystic kidney disease (ADPKD) is the most common hereditary kidney disease. Its progressively expanding, fluid‐filled renal cysts eventually lead to end‐stage renal disease. Despite the relatively high prevalence, treatment options are currently limited to a single drug approved by the FDA and EMA.

Disproportionate enhancement of myocardial contractility by the xanthine oxidase inhibitor oxypurinol in failing rat myocardium

open access: yes, 2003
Objective: Xanthine oxidase (XO) inhibitors enhance myofilament Ca2+ responsiveness of normal rat myocardium. We examined whether this inotropic action is preserved or magnified in failing rat myocardium and whether the magnitude of this effect ...
