Abstract

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.

Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...

Induced Pluripotent Stem Cells01:06

Induced Pluripotent Stem Cells

Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).
Somatic cells are...
