Insights

Malignant gliomas, aggressive brain tumors, harbor gene fusions that drive cancer. Targeting these oncogenic gene fusions offers promising new therapeutic strategies for high-grade gliomas.

Area of Science:

  • Neuro-oncology
  • Cancer Genomics
  • Molecular Biology

Background:

  • Malignant gliomas are molecularly diverse brain tumors with poor patient prognosis.
  • Gene fusions are increasingly recognized as key drivers in gliomagenesis.
  • Current understanding and therapeutic targeting of gene fusions in gliomas remain limited.

Purpose of the Study:

  • To comprehensively review reported gene fusions in high-grade gliomas.
  • To characterize prominent gene fusions and their roles in tumorigenesis.
  • To discuss the clinical implications of these gene fusions as therapeutic targets.

Main Methods:

  • Literature review of studies reporting gene fusions in high-grade gliomas.
  • Analysis of the functional roles of specific gene fusions in oncogenesis.
  • Evaluation of clinical trial data for fusion-targeted therapies.

Main Results:

  • Summary of identified gene fusions in high-grade gliomas.
  • Detailed characterization of frequently observed gene fusions and their oncogenic functions.
  • Preliminary positive outcomes from ongoing clinical trials targeting fusion genes.

Conclusions:

  • Gene fusions represent critical oncogenic drivers in malignant gliomas.
  • Targeting specific gene fusions holds significant potential for personalized glioma treatment.
  • Further research into glioma gene fusions is crucial for developing novel therapies.

Cancer-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.

Loss 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...

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...

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.
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,...

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).
