Abstract:
Androgen receptor (AR) signaling have been frequently targeted for treating prostate cancer (PCa). Even though primarily patients receive a good therapeutic outcome by targeting AR signaling axis, eventually it emerges resistance by altering the genetic makeup of prostate cells. However, to develop an effective therapeutic regime, it is essential to recognize key genetic alterations in PCa. The most common genetic alterations that give rise to distinct androgen different differentiation states are gene fusion of TMPRSS2 with ETS family genes, deletion, or mutation of tumor suppressor PTEN and TP53 gene, amplification or splicing of AR, altered DNA repair genes. In this review, we describe key genes and genetic changes that have been recognized to contribute to altered prostate environment.
Insights
Understanding prostate cancer (PCa) genetic alterations is key to overcoming treatment resistance. This review highlights common genetic changes impacting androgen receptor (AR) signaling in PCa.
Area of Science:
- Oncology
- Genetics
- Molecular Biology
Background:
- Androgen receptor (AR) signaling is a primary target for prostate cancer (PCa) therapy.
- Therapeutic resistance frequently emerges due to genetic alterations in prostate cells.
- Identifying these key genetic changes is crucial for developing effective treatment strategies.
Purpose of the Study:
- To review the critical genes and genetic alterations driving altered prostate cancer environments.
- To provide insights into the genetic basis of treatment resistance in PCa.
Main Methods:
- Literature review of genetic alterations in prostate cancer.
- Analysis of common genetic changes affecting AR signaling and tumor suppression.
Main Results:
- Common genetic alterations include TMPRSS2-ETS gene fusions, PTEN and TP53 mutations/deletions, and AR amplification/splicing.
- Altered DNA repair genes also contribute to the evolving prostate cancer landscape.
- These changes lead to distinct androgen differentiation states and treatment resistance.
Conclusions:
- Recognizing key genetic alterations is essential for advancing PCa therapeutic regimes.
- Understanding these genetic drivers can help predict and overcome treatment resistance.
- Further research into these genetic changes will improve PCa management.

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.

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...
