Insights

Tumor suppressor genes (TSGs) link cancer to other diseases. A network analysis reveals TSGs

Area of Science:

  • Genetics
  • Systems Biology
  • Oncology

Background:

  • Cancer often arises from disruptions in tumor suppressor genes (TSGs).
  • TSG functions extend beyond cancer, implicating them in other human disorders.
  • The human interactome's complexity suggests interconnectedness between diseases via genes.

Purpose of the Study:

  • To construct a comprehensive disease-gene association network for TSGs (TSDN).
  • To explore the role of TSGs in linking cancer with other human diseases.
  • To investigate potential disease-disease associations mediated by TSGs.

Main Methods:

  • Integrated protein-protein interaction networks of TSGs (TSN) with the Online Mendelian Inheritance in Man (OMIM) Morbid Map.
  • Constructed a TSDN to identify disease-gene and disease-disease associations.
  • Analyzed functional protein clusters within the TSN for cohesive disease associations.

Main Results:

  • The TSDN identified links between TSGs and 22 distinct human disorders, including cancer.
  • Revealed significant disease-disease associations mediated by TSGs.
  • High-density functional protein clusters in TSN demonstrated overlapping disease-TSG associations, highlighting TSGs' broad role.

Conclusions:

  • TSGs play a prevalent role in various human diseases, not exclusively cancer.
  • Identified overlapping disease modules and disease-disease associations suggest other conditions may precede cancer.
  • A TSG-based disease association map is a valuable tool for understanding cancer etiology and early prediction.

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 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...

Association Areas of the Cortex01:21

Association Areas of the Cortex

Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

Associative Learning01:27

Associative Learning

Associative learning is a fundamental concept in behavioral psychology, wherein a connection is established between two stimuli or events, leading to a learned response. This process is critical in understanding how behaviors are acquired and modified. Conditioning, the mechanism through which associations are formed, can be divided into two main types: classical conditioning and operant conditioning, each elucidating different aspects of associative learning.
Classical conditioning, also known...

Chromatin Position Affects Gene Expression02:35

Chromatin Position Affects Gene Expression

Chromatin is the massive complex of DNA and proteins packaged inside the nucleus. The complexity of chromatin folding and how it is packaged inside the nucleus greatly influences  access to genetic information. Generally, the nucleus' periphery is considered transcriptionally repressive, while the cell's interior is considered a transcriptionally active area. 
Topologically Associated Domains (TADs)
The 3-dimensional positioning of chromatin in the nucleus influences the...
