Abstract:
Nuclear receptors play an important role in prostate cancer and the androgen receptor is a key transcription factor in regulation of cellular events. Androgen receptor-associated coregulators may be upregulated or downregulated in prostate cancer. Altered expression of regulators may potentiate androgen-induced proliferation, migration, and invasion. Therapies aimed to modulate the function of coregulators in prostate cancer may be based on the use of small molecule inhibitors. Expression and function of AR-associated proteins could be investigated after overexpression and gene silencing followed by hormonal treatment, real-time RT-PCR and ChIP.
Insights
Prostate cancer progression involves altered androgen receptor (AR) coregulators. Modulating these AR-associated proteins with small molecules offers a potential therapeutic strategy for prostate cancer.
Area of Science:
- Oncology
- Molecular Biology
- Endocrinology
Background:
- Nuclear receptors are crucial in prostate cancer.
- The androgen receptor (AR) is a key transcription factor regulating cellular events.
- AR-associated coregulators can be up- or down-regulated in prostate cancer.
Purpose of the Study:
- To investigate the role of AR-associated coregulators in prostate cancer.
- To explore the potential of modulating AR-associated proteins for cancer therapy.
Main Methods:
- Gene silencing and overexpression techniques.
- Hormonal treatment.
- Real-time RT-PCR and Chromatin Immunoprecipitation (ChIP) assays.
Main Results:
