The PGC-1/ERR network and its role in precision oncology

Area of Science:

• Molecular Biology
• Genetics
• Oncology

Background:

• Nuclear receptors (NRs) and their co-regulators control gene expression and are implicated in various pathologies.
• The Nuclear Receptor Signaling Atlas (NURSA) has identified over 600 potential molecules involved in NR signaling.
• Co-regulators are crucial in hormone signaling pathways, suggesting their role in diseases.

Purpose of the Study:

• To discuss the emerging data on the structure, function, and molecular biology of the PGC-1/ERR network.
• To explore the therapeutic potential of NRs/co-activators in precision oncology.
• To highlight new biological insights into PGC-1/ERR for improving cancer outcomes and overcoming therapeutic resistance.

Main Methods:

• Review of existing literature on PGC-1/ERR network.
• Analysis of functional and structural biology of nuclear complexes.
• Discussion of novel technologies like cryo-electron microscopy (cryo-EM) for structural determination.

Main Results:

• PGC-1/ERR network regulates mitochondrial and metabolic genes, making it a promising drug target for cancer.
• Studies have advanced the understanding of NR/co-activator complexes.
• New insights into PGC-1/ERR biology can improve cancer treatment strategies.

Conclusions:

• The PGC-1/ERR network is pivotal in regulating metabolic genes and presents therapeutic opportunities in oncology.
• Further research into NR/co-activator complexes can lead to more effective precision oncology treatments.
• High-resolution structural studies using cryo-EM are essential for novel drug discovery targeting the PGC-1/ERR network.
