Summary
The WW domain-containing oxidoreductase (WWOX) gene acts as a tumor suppressor. High WWOX expression correlates with better survival, suggesting its potential for cancer gene therapy.
Area of Science:
- Genetics
- Molecular Biology
- Oncology
Background:
- The WW domain-containing oxidoreductase (WWOX) gene, located on chromosome 16q 23.3-24.1, is implicated as a tumor suppressor in various cancers.
- WWOX is associated with the common fragile site FRA16D.
Purpose of the Study:
- To elucidate WWOX's protein interactions and molecular mechanisms of tumor suppression.
- To review WWOX's role in the nervous system and in breast, prostate, and ovarian cancers.
Main Methods:
- Literature review and analysis of WWOX gene expression patterns.
- Correlation of WWOX expression levels with cancer prognosis.
Main Results:
- WWOX expression is elevated in endocrine organs.
- Down-regulation of WWOX is observed in many cancers, linked to poorer patient outcomes.
Conclusions:
- WWOX functions as a tumor suppressor gene.
- Elevated WWOX expression is associated with improved disease-free survival, positioning it as a potential target for gene therapy.

01:12Loss of Tumor Suppressor Gene Functions
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

01:05Cancer-Critical Genes II: Tumor Suppressor Genes
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.

01:33Pleiotropy
Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...
02:54Canonical Wnt Signaling Pathway
The gene encoding the main signaling molecules of the Wnt signaling pathways (the Wnt proteins) was discovered almost four decades ago by Nüsslein-Volhard and Wieschaus. They identified and originally named the gene "wingless" (wg) after a phenotype discovered during their landmark genetic screen in Drosophila for body pattern defects. At around the same time, another researcher named Harold Varmus found that a murine tumor virus activates the mammalian wg homolog, Int-1, which results in tumor...
