Insights

Prostate cancer research focuses on androgens and the androgen receptor (AR). Despite therapies, castration-recurrent prostate cancer persists, driving research into AR mechanisms for new drug development.

Area of Science:

  • Oncology
  • Molecular Biology
  • Urology

Background:

  • Prostate cancer remains a leading cause of cancer death in men globally.
  • Androgen deprivation therapy (ADT) is a primary treatment, but castration-recurrent prostate cancer (CRPC) emerges.
  • The androgen receptor (AR) remains central to CRPC, despite decades of research.

Purpose of the Study:

  • To review the persistent role of the androgen receptor (AR) in advanced prostate cancer, particularly in castration-recurrent disease.
  • To explore the mechanisms by which prostate cancer cells evade ADT.
  • To highlight current research directions and the potential for novel therapeutic strategies targeting the AR.

Main Methods:

  • Review of historical and current research on androgens and the androgen receptor in prostate cancer.
  • Analysis of mechanisms driving castration-recurrent prostate cancer (CRPC).
  • Incorporation of findings from genome-wide association studies (GWAS).

Main Results:

  • Prostate cancer remains a significant cause of male mortality despite extensive research and ADT development.
  • CRPC develops in patients who fail ADT, with the AR playing a critical role.
  • Mechanisms of AR reactivation include amplification, mutation, splice variants, alternative pathways, coregulator activity, and intratumoral androgen synthesis.

Conclusions:

  • Understanding AR function under castrate conditions is crucial for overcoming treatment resistance.
  • Emerging knowledge from GWAS and mechanistic studies offers new avenues for drug development.
  • Targeting the AR and its associated pathways holds promise for eradicating advanced prostate cancer.

Intracellular Hormone Receptors

Lipid-soluble hormones diffuse across the plasma and nuclear membrane of target cells to bind to their specific intracellular receptors. These receptors act as transcription factors that regulate gene expression and protein synthesis in the target cell

Testosterone: Functions and Regulation

The intricate hormonal interplay essential for male reproductive health begins with the release of gonadotropin-releasing hormone (GnRH) by the hypothalamus. This hormone prompts the pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). LH targets the Leydig cells in the testes, stimulating them to produce and release testosterone. In concert with testosterone, FSH acts on the Sertoli cells within the seminiferous tubules to facilitate the release of...
Signal Transduction: Overview01:26

Signal Transduction: Overview

Cells respond to many types of information, often through receptor proteins positioned on the membrane. They respond to chemical signals, such as hormones, neurotransmitters, and other signaling molecules, initiating a series of molecular reactions to produce an appropriate response. This is called signal transduction. Cells also coordinate different responses elicited by the same signaling molecule via mediators, allowing molecular cross-talk.
Typically, signal transduction involves three...
