Abstract:
The androgen receptor (AR) signaling pathway regulates the progression of prostate cancer (PC). Metastatic castration-resistant prostate cancer (mCRPC) patients generally receive AR-targeted therapies (ART) or androgen-deprivation therapies (ADT) with the initial response; however, resistance is inevitably observed. Prior studies have shown activity and upregulation of a family of androgen production, uptake, and conversion - APUC genes - based on genomic analyses of patient germlines. Genetic variants of some APUC genes, such as the conversion gene, HSD3B1, predict response to second-generation androgen-targeted therapies. Studies have begun to elucidate the overall role of APUC genes, each with unique actionable enzymatic activity, in mCRPC patient outcomes. The current role and knowledge of the genetic and genomic features of APUC genes in advanced prostate cancer and beyond are discussed in this review. These studies inform of how interpreting behavior of APUC genes through genomic tools will impact the treatment of advanced prostate cancer.
Insights
Androgen production, uptake, and conversion (APUC) genes impact prostate cancer (PC) treatment. Understanding APUC gene variants through genomic analysis can improve outcomes for metastatic castration-resistant prostate cancer (mCRPC) patients.
Area of Science:
- Oncology
- Genetics
- Molecular Biology
Background:
- Androgen receptor (AR) signaling drives prostate cancer (PC) progression.
- Metastatic castration-resistant prostate cancer (mCRPC) patients often develop resistance to standard therapies like androgen-deprivation therapy (ADT) and AR-targeted therapies (ART).
- Genomic analyses reveal the importance of androgen production, uptake, and conversion (APUC) genes in PC.
Purpose of the Study:
- To review the current role and genetic/genomic features of APUC genes in advanced prostate cancer.
- To discuss how understanding APUC gene behavior impacts mCRPC treatment.
- To highlight the actionable enzymatic activities of APUC genes.
Main Methods:
- Genomic analyses of patient germlines.
- Review of existing literature on APUC genes in prostate cancer.
- Elucidation of APUC gene roles in mCRPC patient outcomes.
Main Results:
- APUC genes are active and upregulated in mCRPC.
- Specific genetic variants, like HSD3B1, predict response to second-generation ART.
- APUC genes possess unique, actionable enzymatic activities.
Conclusions:
- Interpreting APUC gene behavior via genomic tools is crucial for advancing mCRPC treatment.
- Further research into APUC genes can personalize and optimize therapy for advanced prostate cancer.
- Understanding genetic variations in APUC genes offers new therapeutic strategies.
