Insights

Kinases were thought to drive cancer, but new research reveals they also act as tumor suppressors. Genomics studies are identifying these crucial tumor-suppressing kinases, changing our understanding of cancer development.

Area of Science:

  • Molecular Biology
  • Oncology
  • Genomics

Background:

  • Kinases are often viewed as oncogenes due to frequent activating mutations in cancer.
  • Kinase inhibitors are established cancer therapeutics, targeting oncogenic kinase functions.
  • Recent cancer genomics studies reveal a significant role for kinases as tumor suppressors.

Purpose of the Study:

  • To review the evolving understanding of kinases in cancer.
  • To highlight the discovery and identification of tumor-suppressing kinases.
  • To discuss historical and modern approaches for identifying these kinases.

Main Methods:

  • Review of existing literature on kinase functions in cancer.
  • Analysis of cancer genomics data, particularly loss-of-function mutation screens.
  • Bioinformatic approaches for identifying tumor-suppressing kinases.

Main Results:

  • Kinases play a dual role in cancer, acting as both oncogenes and tumor suppressors.
  • Examples of tumor-suppressing kinases include Protein Kinase C (PKC) family, MKK4, and DAPK3.
  • Modern bioinformatic and genomic approaches facilitate the identification of novel tumor-suppressing kinases.

Conclusions:

  • The characterization of kinases as tumor suppressors is a significant shift in cancer research.
  • Understanding the tumor-suppressive functions of kinases opens new avenues for cancer therapy.
  • Continued research and advanced methodologies are crucial for uncovering the full spectrum of kinase roles in tumorigenesis.

Master Transcription Regulators02:23

Master Transcription Regulators

Master transcription regulators are regulatory proteins that are predominantly responsible for regulating the expression of multiple genes. Often these genes work in concert to drive a  complex process. Activation of a master transcription regulator can lead to a cascade of transcriptional activation necessary for that outcome. These regulators can directly bind to the regulatory sequences of the various genes involved, or they can indirectly regulate transcription by binding to regulatory...

Protein Kinases and Phosphatases

Proteins undergo chemical modifications that trigger changes in the charge, structure, and conformation of the proteins. Phosphorylation, acetylation, glycosylation, nitrosylation, ubiquitination, lipidation, methylation, and proteolysis are various protein modifications that regulate protein activity. Such modifications are usually enzyme-driven.
Protein kinases
Many proteins in the cell are regulated by phosphorylation, the addition of a phosphate group. A family of enzymes called kinases...

Regulated Protein Degradation02:58

Regulated Protein Degradation

It is vital to regulate the activity of enzymatic as well as non-enzymatic proteins inside the cell. This can be achieved either through creating a balance between their rate of synthesis and degradation or regulating the intrinsic activity of the protein. Both these regulation mechanisms play an essential role in the normal functioning of cells.
Protein degradation plays two important roles in the cells. It helps to protect cells from misfolded or damaged proteins before they lead to a...

Detection of Black Holes

Although black holes were theoretically postulated in the 1920s, they remained outside the domain of observational astronomy until the 1970s.
Their closest cousins are neutron stars, which are composed almost entirely of neutrons packed against each other, making them extremely dense. A neutron star has the same mass as the Sun but its diameter is only a few kilometers. Therefore, the escape velocity from their surface is close to the speed of light.
Not until the 1960s, when the first neutron...
