Long-term environmental exposure to metals leads to epigenetic changes and may increase risks to human health. The human epidemiologic and the toxicologic animal model studies provide strong evidence of metal exposure related DNA methylation changes, and, consequently alterations in gene expression, in metabolic, genetic and signal transduction pathways and their functions. The current study is designed to investigate genome wide DNA methylation and transcriptomic changes induced by human chronic ...

Space radiation (IR) from Solar Particle Events (SPE) and Galactic Cosmic Rays (GCR), also known as high charge and energy (HZE) IR, is a primary risk associated with deep-space missions. There are limited animal and human studies on the risk of cardiovascular disease (CVD) development due to space-IR. The cardiac effects induced by space-type IR, specifically simplified GCR simulated (simGCRsim)-IR, are yet to be discovered. We hypothesized that gamma (γ) and simGCRsim IR-induced biological ...

Sequencing raw data.

This dataset provides data necessary to replicate the results of the time-perturbation analysis of gene expression in health and mental disorders. The corresponding code is available in the GitHub repository under the https://github.com/susieavagyan/BrainExp-TemporalDynamics link.

The Pathway Signal Flow (PSF) toolkit is an R package designed for pathway editing and signal flow analysis. It enables users to perform PSF analysis on functional -omics data, facilitating the study of signaling pathways in various biological contexts.

Key Features:

• Pathway Editing: Allows customization and editing of biological pathways to suit specific research needs.

• Signal Flow Calculation: Computes signal flow within pathways based on gene expression data, aiding in the ...

KEGG pathway database is a collection of manually drawn pathway maps representing current knowledge on molecular interaction and reaction networks, accompanied with KGML (KEGG pathway xml format) files for automatic computational analyses and modeling of metabolic and signaling networks. In a KGML file the pathway is represented as a graph object with entry elements (gene products, compounds, pathways) as its nodes, and relations between elements as edges. However, in most cases there is a lack ...

Patient-specific induced pluripotent stem cells (iPSCs) are reprogrammed somatic cells derived from individual patients through the expression of key transcription factors (e.g., OCT4, SOX2, KLF4, and c-MYC). These cells exhibit pluripotency, allowing them to differentiate into various cell types and serve as in vitro models for studying disease mechanisms, drug screening, and regenerative medicine.
