Abstract:
Despite aggressive treatment and androgen-deprivation therapy, most prostate cancer patients ultimately develop castration-resistant prostate cancer (CRPC), which is associated with high mortality rates. However, the mechanisms governing the development of CRPC are poorly understood, and androgen receptor (AR) signaling has been shown to be important in CRPC through AR gene mutations, gene overexpression, co-regulatory factors, AR shear variants, and androgen resynthesis. A growing number of non-AR pathways have also been shown to influence the CRPC progression, including the Wnt and Hh pathways. Moreover, non-coding RNAs have been identified as important regulators of the CRPC pathogenesis. The present review provides an overview of the relevant literature pertaining to the mechanisms governing the molecular acquisition of castration resistance in prostate cancer, providing a foundation for future, targeted therapeutic efforts.
Insights
Castration-resistant prostate cancer (CRPC) develops despite treatment due to complex molecular changes. Understanding these mechanisms, including androgen receptor (AR) signaling and other pathways, is crucial for developing new therapies.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Prostate cancer frequently progresses to castration-resistant prostate cancer (CRPC) despite androgen-deprivation therapy.
- CRPC is linked to high mortality rates, and its underlying mechanisms remain incompletely understood.
- Androgen receptor (AR) signaling plays a critical role in CRPC development through various alterations.
Purpose of the Study:
- To review the molecular mechanisms driving the development of castration resistance in prostate cancer.
- To consolidate current knowledge on AR-dependent and independent pathways involved in CRPC pathogenesis.
- To provide a foundation for future therapeutic strategies targeting CRPC.
Main Methods:
- Literature review of relevant scientific publications.
- Analysis of studies investigating molecular alterations in prostate cancer progression.
- Synthesis of findings on AR signaling, non-AR pathways, and non-coding RNAs in CRPC.
Main Results:
- AR signaling is implicated in CRPC via gene mutations, overexpression, co-regulatory factors, splice variants, and androgen resynthesis.
- Non-AR pathways, such as Wnt and Hedgehog (Hh), significantly influence CRPC progression.
- Non-coding RNAs are emerging as key regulators in the pathogenesis of CRPC.
Conclusions:
- The acquisition of castration resistance in prostate cancer is a multifactorial process involving AR signaling, alternative pathways, and non-coding RNAs.
- A comprehensive understanding of these molecular mechanisms is essential for advancing CRPC treatment.
- This review highlights the need for targeted therapeutic efforts based on the identified molecular drivers of CRPC.
