Background:
The p160 steroid receptor coactivator (SRC) family is critical to the transcriptional activation function of nuclear hormone receptors. A key member of this family is SRC-3, initially found to be amplified and expressed in breast cancer it has subsequent been shown to be expressed in malignant disease arising from a wide range of other organs. An understanding of the potential role of SRC-3 in the pathogenesis and its possible prognostic role in a broad range of tumours will improve our general understanding of carcinogenesis as well as potentially leading to a new prognostic marker as well as new therapeutic targets.
Methods:
Relevant papers were identified by searching the PubMed and MEDLINE databases for article published until 28th February 2009. Only articles published in English were considered. The search terms included "SRC-3", "AIB1" in association with the following terms: "human", "cancer" and "malignant disease". The search focused on malignant disease arising outside of the mammary gland. Full articles were obtained and references were checked for additional material when appropriate.
Results:
SRC-3 is amplified and expressed in a wide spectrum of human malignant diseases and appears to be a potential prognostic marker in a number of different tumours.
Conclusion:
SRC-3 appears to be implicated in the possible risk of developing prostate and ovarian cancer. Its presence appears to be a marker of aggressive disease. Further research is required to determine its predictive and prognostic utility given the relative paucity of studies for each specific malignant disease.
Insights
Steroid receptor coactivator-3 (SRC-3) is overexpressed in many cancers and may serve as a prognostic marker for aggressive disease, particularly in prostate and ovarian cancers.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- The p160 steroid receptor coactivator (SRC) family, including SRC-3, plays a crucial role in nuclear hormone receptor transcriptional activity.
- SRC-3 amplification and expression are observed in breast cancer and other malignant diseases.
- Understanding SRC-3's role in carcinogenesis may yield new prognostic markers and therapeutic targets.
Purpose of the Study:
- To review the literature on SRC-3 expression in human malignant diseases outside the breast.
- To assess the potential prognostic and predictive value of SRC-3 in various cancers.
- To identify potential therapeutic implications of SRC-3 in oncology.
Main Methods:
- A comprehensive literature search of PubMed and MEDLINE databases was conducted up to February 28, 2009.
- English-language articles were included, using search terms "SRC-3", "AIB1", "human", "cancer", and "malignant disease".
- The focus was on malignant diseases originating outside the breast, with full article retrieval and reference checking.
Main Results:
- SRC-3 is amplified and expressed across a broad spectrum of human cancers.
- SRC-3 expression shows potential as a prognostic marker in diverse tumor types.
- Evidence suggests SRC-3 involvement in the risk of developing prostate and ovarian cancers.
Conclusions:
- SRC-3 is implicated in the pathogenesis of prostate and ovarian cancers.
- SRC-3 presence correlates with aggressive disease characteristics.
- Further research is needed to fully establish SRC-3's predictive and prognostic utility due to limited studies per cancer type.
