Tumor suppressor genes play a role in acute myelogenous leukemia (AML) development. While mutations in p53 and Retinoblastoma (Rb) genes are uncommon in AML, expression abnormalities in several related genes are observed.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Acute myelogenous leukemia (AML) is a complex blood cancer.
- Cancer development often involves the disruption of tumor suppressor genes.
- Understanding these disruptions is key to comprehending AML pathogenesis.
Purpose of the Study:
- To review the current literature on tumor suppressor genes in AML.
- To explore the potential involvement of these genes in AML development.
Main Methods:
- Literature review of studies on tumor suppressor genes in AML.
- Analysis of mutation and expression data for key genes.
Main Results:
- Mutations in p53 and Retinoblastoma (Rb) genes are infrequent in AML compared to solid tumors.
- Expression abnormalities are noted in several tumor suppressor genes and related genes, including MDM2, p73, Rb, p14(ARF), p15(INK4B), and p16(INK4A).
Conclusions:
- Despite uncommon mutations in p53 and Rb, altered expression of other tumor suppressor genes is significant in AML.
- These genetic alterations likely contribute to the evasion of normal regulatory controls in AML pathogenesis.

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.

Loss of Tumor Suppressor Gene Functions
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...

The Retinoblastoma Gene
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
