Insights

The Hippo pathway, a cancer suppressor, is regulated by the ubiquitin system. Its deregulation promotes cancer by increasing YAP/TAZ activity, offering new therapeutic targets.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cell Signaling

Background:

  • The Hippo pathway is a critical regulator of cell proliferation and organ size, acting as a tumor suppressor.
  • Yeast and TAZ are key downstream effectors of the Hippo pathway; their aberrant activation drives oncogenesis.
  • Dysregulation of the Hippo pathway is a common feature in various human cancers.

Purpose of the Study:

  • To review the role of the ubiquitin system in regulating the mammalian Hippo pathway.
  • To explore the implications of Hippo pathway deregulation in cancer.
  • To discuss potential strategies for targeting the Hippo pathway via the ubiquitin system for cancer therapy.

Main Methods:

  • Literature review of recent studies on ubiquitin-mediated Hippo pathway regulation.
  • Analysis of the role of ubiquitin ligases and deubiquitinating enzymes in Hippo signaling.
  • Examination of cancer-related studies involving Hippo pathway components.

Main Results:

  • The ubiquitin system extensively modulates Hippo pathway components, including LATS kinases and YAP/TAZ.
  • Specific ubiquitin ligases and deubiquitinating enzymes have been identified as key regulators of YAP/TAZ activity.
  • Aberrant ubiquitination of Hippo pathway proteins contributes to oncogenic transformation and tumor progression.

Conclusions:

  • Ubiquitin-mediated regulation is crucial for maintaining Hippo pathway homeostasis.
  • Targeting ubiquitin system components offers a promising avenue for developing novel cancer therapeutics.
  • Further research into the ubiquitin-Hippo pathway interplay is warranted for clinical applications.

NF-κB-dependent Signaling Pathway02:26

NF-κB-dependent Signaling Pathway

The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

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...

cAMP-dependent Protein Kinase Pathways01:25

cAMP-dependent Protein Kinase Pathways

Cyclic Adenosine Monophosphate (cAMP) is an essential second messenger that activates protein kinase A (PKA) and regulates various biological processes. A single epinephrine molecule binds to GPCR and activates several heterotrimeric G proteins, each stimulating multiple adenylyl cyclase, amplifying the signal, and synthesizing large numbers of cAMP molecules. Small changes in cAMP concentration affect PKA activity. The binding of four cAMP molecules induces a conformational change in PKA,...

Covalently Linked Protein Regulators02:04

Covalently Linked Protein Regulators

Proteins can undergo many types of post-translational modifications, often in response to changes in their environment. These modifications play an important role in the function and stability of these proteins. Covalently linked molecules include functional groups, such as methyl, acetyl, and phosphate groups, and also small proteins, such as ubiquitin. There are around 200 different types of covalent regulators that have been identified.
These groups modify specific amino acids in a protein....

Regulation of Expression Occurs at Multiple Steps02:24

Regulation of Expression Occurs at Multiple Steps

Gene expression can be regulated at almost every step from gene to protein. Transcription is the step that is most commonly regulated. This involves the binding of proteins to short regulatory sequences on the DNA. This association can either promote or inhibit the transcription of a gene associated with the respective sequence.
Transcription results in the generation of precursor (pre-mRNA) that consists of both exons and introns, which needs further processing before being translated to a...

GTPases and their Regulation02:14

GTPases and their Regulation

Guanine nucleotide-binding proteins (G-proteins), also known as GTPases, are a superfamily of proteins that regulate many cellular processes, such as cell signaling, vesicular transport, and the regulation of cell shape and motility. Mutation or dysfunction of these proteins can lead to disease. There are around 40,000 known G-proteins that can broadly be classified into two groups ‒  small G-proteins consisting of a single domain and large multi-domain G-proteins.
Large G-proteins,...
