Cancer-Critical Genes II: Tumor Suppressor Genes

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...

TGF - β Signaling Pathway

TGF - β Signaling Pathway

The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors are of three kinds RI, RII, and RIII. The RI...

Loss of Tumor Suppressor Gene Functions

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...

The Retinoblastoma Gene

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,...

Area of Science:

Oncology
Molecular Biology
Cancer Signaling

Background:

The transforming growth factor-beta (TGF-beta) signaling pathway plays a dual role in cancer, with some functions suppressing tumor formation and others promoting progression.
The TGF-beta/Smad signaling axis is a key component of this pathway, influencing various cellular processes relevant to cancer.

Purpose of the Study:

To present evidence supporting a tumor-suppressive role for the TGF-beta/Smad signaling axis.
To explore therapeutic strategies for cancer treatment that modulate TGF-beta pathway activities.

Main Methods:

Compilation of data from cell culture studies.
Analysis of animal models of cancer.
Examination of human tumor samples.
Investigation of genetic polymorphisms in TGF-beta pathway components and their association with cancer risk.

Main Results:

Evidence from multiple research avenues supports a tumor-suppressive role for the TGF-beta/Smad pathway.
Polymorphisms in TGF-beta pathway components are linked to cancer risk, further underscoring the pathway's significance.

Conclusions:

The TGF-beta/Smad signaling axis demonstrates significant tumor-suppressive activities.
Therapeutic strategies could involve enhancing TGF-beta's tumor-suppressive functions or inhibiting its pro-tumorigenic roles in cancer treatment.
