Transcriptional and epigenomic analysis of insulin sensitivity in human adipocytes.
CRISPRi analysis reveals two key enhancer regions regulating IRS1 expression linked to human insulin sensitivity and resistance.
- Why it matters: Understanding the molecular basis of insulin resistance in adipocytes is crucial for developing targeted therapies for type 2 diabetes and related diseases.
- What they did: The study involved transcriptional and epigenomic profiling of adipocytes from individuals with and without insulin resistance, focusing on regions near IRS1, and used CRISPRi to identify regulatory elements.
- The result: Findings pinpoint specific enhancer regions and transcription factors that control IRS1 expression, advancing knowledge of the molecular mechanisms underlying insulin sensitivity and resistance.
