Glucocorticoid regulation of the human noncoding genome.

Glucocorticoids regulate over 2000 noncoding transcripts in a cell type-specific manner across nine human primary cell types.

• Why it matters: Understanding GC effects on noncoding RNAs is crucial because these transcripts may influence tissue-specific responses, resistance, or sensitivity to GC therapy, yet remain poorly characterized.
• What they did: The study applied in vitro GC treatment to nine human primary cell types, performing transcriptomic profiling at 2 and 6 hours to identify GC-responsive noncoding RNAs, including lncRNAs and miRNAs.
• The result: More than 2000 GC-responsive noncoding transcripts were identified, with 80% of lncRNAs and 97% of miRNAs being unique to a single cell type, providing a resource for exploring noncoding RNA roles in GC responses.
