Peroxisome proliferator-activated receptor beta/delta (PPARβ/δ) regulates genes involved in metabolism and cancer. Its complex role in cancer processes is partly understood, but it shows potential as an anti-cancer drug target.
Area of Science:
- Molecular Biology
- Cancer Research
- Endocrinology
Background:
- The nuclear receptor peroxisome proliferator-activated receptor beta/delta (PPARβ/δ) regulates target genes via transcriptional mechanisms.
- PPARβ/δ is crucial for intermediary metabolism, inflammation, differentiation, and apoptosis.
- Clinical data suggest a link between PPARβ/δ expression and poor outcomes in several human cancers.
Purpose of the Study:
- To review the multifaceted role of PPARβ/δ in cancer.
- To discuss the complex transcriptional regulation mechanisms of PPARβ/δ.
- To explore the potential of PPARβ/δ as a druggable anti-cancer target.
Main Methods:
- Literature review of research on PPARβ/δ in cancer.
- Analysis of transcriptional regulation mechanisms (ligand-dependent/independent, co-factor interactions).
- Discussion of clinical associations and controversial findings regarding PPARβ/δ in cancer.
Main Results:
- PPARβ/δ's role in cancer is mechanistically complex and not fully understood.
- Existing data present a controversial picture of PPARβ/δ's involvement in cancer.
- PPARβ/δ influences critical cellular processes relevant to cancer development and progression.
Conclusions:
- PPARβ/δ has a significant, albeit complex and partly controversial, role in human cancers.
- Understanding PPARβ/δ's intricate regulatory mechanisms is key to elucidating its function in cancer.
- PPARβ/δ represents a promising, druggable target for anti-cancer therapies.

The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
