Repressing Gene Transcription by Redirecting Cellular Machinery with Chemical Epigenetic Modifiers
Published on: September 20, 2018
Abstract:
A new class of designer drugs can reprogram gene expression by linking a transcription factor that silences genes involved in cell death with an epigenetic regulator that stimulates gene activity. A prototype molecule showed robust potency in flipping the function of BCL6, a protein that supports lymphoma cell proliferation, offering a promising therapeutic approach to combat cancer cell growth.
Insights
Scientists developed designer drugs to control gene expression, reprogramming cell death pathways. A prototype molecule effectively targeted BCL6, showing potential for cancer therapy by inhibiting lymphoma cell growth.
Area of Science:
- Molecular Biology
- Epigenetics
