A new knowledge graph, ReproTox-KG, identifies potential teratogens by analyzing drug and gene associations with birth defects. This resource aids in predicting risks from preclinical small molecules and understanding molecular mechanisms.
Area of Science:
- Biomedical Informatics
- Toxicology
- Genetics
Background:
- Birth defects affect approximately 1 in 33 US births, with many having unknown causes.
- Potential contributing factors include genetic elements, environmental pollutants, and drug exposure during pregnancy.
Purpose of the Study:
- To develop a comprehensive knowledge graph (ReproTox-KG) to characterize associations between small molecules, genes, and birth defects.
- To identify molecular mechanisms underlying drug-induced birth defects.
Main Methods:
- Constructed ReproTox-KG by integrating data on drug/birth-defect co-mentions, gene/birth-defect associations, gene expression changes, drug targets, genetic burden scores, and placental crossing.
- Applied semi-supervised learning (SSL) to score preclinical small molecules for teratogenic potential.
Main Results:
- Scored over 30,000 preclinical small molecules for placental crossing and birth defect induction potential.
- Identified over 500 birth-defect/gene/drug cliques to elucidate drug-induced birth defect mechanisms.
- Launched a web-based interface for ReproTox-KG: https://maayanlab.cloud/reprotox-kg.
Conclusions:
- ReproTox-KG serves as a valuable resource for understanding birth defect molecular mechanisms.
- The platform can predict the teratogenic potential of genes and preclinical small molecules.

Toxic Reactions: Overview
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...

The ER provides optimal conditions for synthesizing steroid hormones and lipids, such as phospholipids and triglycerides. Traditionally, lipid metabolism was considered to be a smooth ER function. However, there is no direct evidence to prove that rough ER is completely excluded from lipid...
