Aggressive prostate cancer is driven by androgen receptor signaling, tumor cell adaptability, and genetic mutations. Understanding these factors is key to improving treatment strategies for advanced prostate cancer.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Prostate cancer progression and aggressiveness are complex processes.
- Key molecular pathways and genetic alterations influence tumor behavior.
Purpose of the Study:
- To identify the critical molecular factors contributing to aggressive prostate cancer.
- To understand the role of androgen receptor signaling and genetic defects in tumor cell behavior.
Main Methods:
- Review of current literature on prostate cancer molecular mechanisms.
- Analysis of genetic alterations and signaling pathway dysregulation in aggressive prostate cancer.
Main Results:
- Androgen receptor (AR) function is central to prostate cancer development and progression.
- Tumor cell plasticity, including neuroendocrine differentiation, promotes aggressiveness.
- Loss of tumor suppressor genes and DNA repair defects significantly impact prostate cancer cell behavior and treatment resistance.
Conclusions:
- AR signaling, tumor cell plasticity, tumor suppressor loss, and DNA repair defects are key drivers of aggressive prostate cancer.
- Targeting these pathways and understanding genetic vulnerabilities are crucial for developing effective therapies for advanced disease.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
Cancer-Critical Genes I: Proto-oncogenes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
