Insights

E3 ligases are crucial enzymes regulating protein degradation and cellular balance. This review explores their role in cancer and highlights bioactive compounds targeting E3 ligases for potential anticancer therapies.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Oncology

Background:

  • E3 ligases are enzymes essential for cellular homeostasis through ubiquitin-mediated protein degradation.
  • The ubiquitin-proteasome system (UPS) regulates oncogenic and tumor-suppressive proteins, making E3 ligases significant targets.
  • E3 ligases are classified into HECT, RING, and RBR types based on structure and function.

Purpose of the Study:

  • To review the critical roles of E3 ligases in cancer development.
  • To discuss existing bioactive compounds that target E3 ligases for anticancer activity.
  • To emphasize the need for developing novel E3 ligase-targeting therapeutics.

Main Methods:

  • Literature review of E3 ligase functions in cancer.
  • Analysis of the ubiquitin-proteasome system (UPS) in oncogenesis.
  • Survey of bioactive compounds targeting E3 ligases.

Main Results:

  • E3 ligases play pivotal roles in cancer by regulating key proteins.
  • Several classes of E3 ligases (HECT, RING, RBR) are implicated in tumorigenesis.
  • Various small molecules targeting E3 ligases show promise for anticancer drug development.

Conclusions:

  • E3 ligases are vital targets for anticancer drug discovery.
  • Targeting E3 ligases offers a promising strategy for cancer therapy.
  • Further development of bioactive compounds against E3 ligases is warranted.

Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

Targeted Cancer Therapies02:57

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...

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....

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

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...

Receptor Downregulation in MVBs01:15

Receptor Downregulation in MVBs

Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that  lead to cell proliferation, migration, and differentiation. Overexpression of EGFR  stimulates cells to proliferate. Excessive  EGFR...
