Insights

Tumour suppressor genes (TSGs) play a crucial role in preventing cancer by regulating cell functions. Loss of TSGs contributes to oncogenesis, offering new insights into basic cell biology and cancer development.

Area of Science:

  • Molecular Biology
  • Cancer Genetics
  • Cellular Biology

Background:

  • Tumour development often involves proto-oncogene activation.
  • Emerging evidence highlights the role of tumour suppressor genes (TSGs) inactivation in oncogenesis.
  • TSGs are critical regulators of cellular processes.

Purpose of the Study:

  • To explore the functions of tumour suppressor gene products.
  • To understand the contribution of TSG inactivation to oncogenesis.
  • To investigate the role of TSG products in basic cell biology.

Main Methods:

  • Molecular analysis of tumour suppressor genes.
  • Examination of protein products of TSGs.
  • Comparative studies with normal cell investigations.

Main Results:

  • TSG protein products are involved in diverse cellular functions including cell adhesion, signal transduction, transcription, translation, and cell cycle control.
  • Many TSG products were novel findings, not previously identified in normal cells.
  • Analysis of TSGs significantly advances understanding of both oncogenesis and fundamental cell biology.

Conclusions:

  • Inactivation of tumour suppressor genes is a key mechanism in cancer development.
  • TSG products are integral to fundamental cellular processes.
  • Research into TSGs offers dual benefits for cancer research and basic cell biology.

Loss of Tumor Suppressor Gene Functions01:12

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...

Cancer-Critical Genes II: Tumor Suppressor Genes01:05

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.
Such genes that act...

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...
mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...
