Androgen receptor in hepatocarcinogenesis: Recent developments and perspectives

Area of Science:

• Oncology
• Molecular Biology
• Endocrinology

Background:

• Males exhibit a higher incidence of hepatocellular carcinoma (HCC) than females.
• Understanding the molecular mechanisms behind this gender disparity is crucial for hepatocarcinogenesis research.
• The androgen receptor (AR) has emerged as a key factor in HCC gender differences.

Purpose of the Study:

• To review the role of androgen receptor (AR) signaling in hepatocellular carcinoma (HCC).
• To explore the dual function of AR in promoting HCC initiation and suppressing metastasis.
• To discuss novel therapeutic strategies targeting AR for HCC treatment.

Main Methods:

• Literature review of genetic and molecular studies on AR in HCC.
• Analysis of direct AR transcriptional target genes implicated in HCC.
• Examination of current theories on AR signaling in hepatocarcinogenesis.

Main Results:

• Genetic studies confirm the androgen receptor (AR) contributes to gender disparity in HCC.
• AR plays a dual role: promoting HCC initiation and development, while suppressing metastasis.
• Specific AR transcriptional targets involved in HCC have been identified.

Conclusions:

• Targeting the androgen receptor (AR) may offer a more effective therapeutic strategy for HCC than targeting androgens.
• Further research into AR signaling pathways can elucidate novel treatment approaches for hepatocellular carcinoma.
• The review highlights the complex role of AR in HCC, impacting both tumor progression and metastatic potential.
