Insights

Runt-related transcription factor 3 (RUNX3) typically suppresses tumors but can act as an oncogene when overexpressed. In head and neck cancer, RUNX3 overexpression promotes malignancy by increasing cell growth and inhibiting apoptosis.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cancer Research

Background:

  • Runt-related transcription factor 3 (RUNX3) is recognized for its tumor-suppressive functions in various cancers.
  • RUNX3 is a key player in the transforming growth factor-β (TGF-β)-mediated tumor suppression pathway.
  • However, RUNX3 can exhibit oncogenic properties when its expression is elevated.

Purpose of the Study:

  • To review the dual role of RUNX3 in cancer, focusing on its oncogenic function.
  • To highlight the specific role of RUNX3 overexpression in head and neck cancer.
  • To discuss the implications of RUNX3 as an oncogene in malignant behaviors.

Main Methods:

  • Literature review of studies investigating RUNX3 in cancer.
  • Analysis of evidence linking RUNX3 expression levels to tumor behavior.
  • Examination of molecular mechanisms underlying RUNX3's oncogenic activity.

Main Results:

  • RUNX3 overexpression is frequently observed in head and neck cancer.
  • Elevated RUNX3 levels correlate with malignant characteristics in these tumors.
  • RUNX3 overexpression enhances cell proliferation and suppresses apoptosis in head and neck cancer cells.

Conclusions:

  • RUNX3 can function as an oncogene, particularly in head and neck cancer.
  • RUNX3 overexpression contributes to tumor progression by promoting cell growth and inhibiting cell death.
  • Understanding RUNX3's oncogenic role is crucial for developing targeted cancer therapies.

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.

The Retinoblastoma Gene

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,...

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...

Small GTPases - Ras and Rho

Ras and Rho are small monomeric GTPases that act downstream of receptor tyrosine kinase (RTK) and regulate various cellular processes. These GTPases switch between active and inactive states by binding to guanine nucleotides.
