Emerging roles for the pro-oncogenic anterior gradient-2 in cancer development
Oncogene
|September 5, 2012
Summary
Anterior gradient 2 (AGR2) protein, overexpressed in many cancers, drives metastatic growth by regulating protein folding and secretion. Targeting AGR2 pathways offers potential for novel cancer drug discovery and therapy response prediction.
Area of Science:
- Oncology
- Molecular Biology
- Biochemistry
Background:
- Cancer phenotype is not fully predicted by genetic blueprints alone.
- Signaling hubs mediating cancer phenotype are identified using OMICS platforms.
- Anterior gradient 2 (AGR2) is a pro-oncogenic protein implicated in various diseases, including cancer.
Purpose of the Study:
- To review the molecular biology of AGR2.
- To explore AGR2's role in cancer progression and metastasis.
- To discuss AGR2's potential as a biomarker and therapeutic target.
Main Methods:
- Literature review of AGR2 molecular biology.
- Analysis of AGR2 expression in human cancers.
- Examination of AGR2's role in protein folding, maturation, and secretion.
Main Results:
- AGR2 is overexpressed in diverse human cancers and secreted.
- AGR2, an endoplasmic reticulum-resident protein, influences protein folding and secretion.
- AGR2 overexpression is linked to metastatic growth and drug resistance.
Conclusions:
- AGR2 is a significant pro-oncogenic signaling intermediate.
- AGR2's role in secretion and metastasis makes it a target for drug discovery.
- AGR2 may serve as a predictive biomarker for therapy response.

01:33Cancer-Critical Genes I: Proto-oncogenes
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
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.

02:53Adaptive Mechanisms in Cancer Cells
Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...
