Insights

Targeted therapies inhibiting receptor tyrosine kinases (RTKs) are revolutionizing cancer treatment. Blocking RET proto-oncogene activity shows promise for thyroid cancer, reverting neoplastic characteristics in preclinical models.

Area of Science:

  • Oncology
  • Molecular Biology
  • Pharmacology

Background:

  • Receptor tyrosine kinases (RTKs) are crucial in cancer development.
  • Gain-of-function alterations in the RET proto-oncogene drive thyroid carcinomas.
  • Targeted inhibition of RTKs represents a significant advance in cancer therapy.

Purpose of the Study:

  • To evaluate the RET proto-oncogene as a therapeutic target for thyroid cancer.
  • To explore strategies for blocking RET activity in preclinical cancer models.

Main Methods:

  • Review of existing literature on RTK inhibitors and RET proto-oncogene.
  • Analysis of preclinical models targeting RET activity.
  • Assessment of the impact of RET inhibition on neoplastic characteristics.

Main Results:

  • RET alterations are implicated in medullary and papillary thyroid carcinoma.
  • Inhibition of RET activity demonstrated potential in preclinical models.
  • Blocking RET reverted key neoplastic characteristics.

Conclusions:

  • The RET proto-oncogene is a viable target for selective cancer therapies, particularly for thyroid cancer.
  • Further development of RET inhibitors is warranted, building on successes with other tyrosine kinase inhibitors.

Cancer-Critical Genes I: Proto-oncogenes

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...

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,...

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against specific...
