Abstract:
The androgen receptor (AR) is a key regulator of prostate growth and the principal drug target for the treatment of prostate cancer. Previous studies have mapped AR targets and identified some candidates which may contribute to cancer progression, but did not characterize AR biology in an integrated manner. In this study, we took an interdisciplinary approach, integrating detailed genomic studies with metabolomic profiling and identify an anabolic transcriptional network involving AR as the core regulator. Restricting flux through anabolic pathways is an attractive approach to deprive tumours of the building blocks needed to sustain tumour growth. Therefore, we searched for targets of the AR that may contribute to these anabolic processes and could be amenable to therapeutic intervention by virtue of differential expression in prostate tumours. This highlighted calcium/calmodulin-dependent protein kinase kinase 2, which we show is overexpressed in prostate cancer and regulates cancer cell growth via its unexpected role as a hormone-dependent modulator of anabolic metabolism. In conclusion, it is possible to progress from transcriptional studies to a promising therapeutic target by taking an unbiased interdisciplinary approach.
Insights
Researchers identified a new anabolic pathway regulated by the androgen receptor (AR) in prostate cancer. Targeting calcium/calmodulin-dependent protein kinase kinase 2 shows promise for inhibiting tumor growth by modulating metabolism.
Area of Science:
- Oncology
- Molecular Biology
- Metabolomics
Background:
- The androgen receptor (AR) is crucial for prostate growth and a primary target in prostate cancer therapy.
- Previous research identified AR targets but lacked integrated AR biology characterization.
- Understanding AR's role in anabolic pathways is key for developing new cancer treatments.
Purpose of the Study:
- To identify and characterize an anabolic transcriptional network regulated by the AR in prostate cancer.
- To find AR targets involved in anabolic processes that could be therapeutically targeted.
- To explore novel therapeutic strategies by restricting tumor cell metabolism.
Main Methods:
- Integrated genomic studies and metabolomic profiling.
- Analysis of AR targets involved in anabolic pathways.
- Investigating the role of calcium/calmodulin-dependent protein kinase kinase 2 in prostate cancer.
Main Results:
- Anabolic transcriptional network with AR as the core regulator was identified.
- Calcium/calmodulin-dependent protein kinase kinase 2 (CaMKK2) was found to be overexpressed in prostate cancer.
- CaMKK2 acts as a hormone-dependent modulator of anabolic metabolism, regulating cancer cell growth.
Conclusions:
- An interdisciplinary approach can identify promising therapeutic targets from transcriptional studies.
- CaMKK2 is a potential therapeutic target for prostate cancer due to its role in anabolic metabolism.
- Restricting flux through anabolic pathways is a viable strategy for depriving tumors of essential building blocks.
