Insights

E3 ubiquitin ligases are highly expressed in gastric cancer, promoting its development. Targeting these ligases offers potential new treatments for gastric cancer patients.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Oncology

Background:

  • E3 ubiquitin ligases are crucial for protein degradation via the 26S proteasome.
  • These ligases regulate vital cellular processes such as cell cycle, proliferation, and apoptosis.
  • Aberrant E3 ubiquitin ligase expression is implicated in various cancers, including gastric cancer.

Purpose of the Study:

  • To review the clinical significance of E3 ubiquitin ligases in gastric cancer (GC).
  • To discuss the potential of targeting E3 ubiquitin ligases for novel GC therapies.

Main Methods:

  • Literature review of current knowledge on E3 ubiquitin ligases in GC.
  • Analysis of the role of E3 ubiquitin ligases in gastric carcinogenesis.
  • Evaluation of pharmaceutical intervention strategies targeting the ubiquitin-proteasome system.

Main Results:

  • E3 ubiquitin ligases are frequently overexpressed in GC tissues.
  • These ligases contribute significantly to the development and progression of gastric cancer.
  • The proteasome inhibitor Bortezomib highlights the therapeutic potential of targeting the ubiquitin-proteasome system.

Conclusions:

  • E3 ubiquitin ligases represent important targets for gastric cancer treatment.
  • Novel therapeutic strategies focusing on aberrant E3 ubiquitin ligases show promise for GC intervention.

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...

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...

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...

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal

Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.

Gastritis II: Pathophysiology

The pathophysiology of gastritis begins with the colonization of the stomach lining by Helicobacter pylori (H. pylori). This bacterium spreads mainly via the oral-oral route through saliva or shared utensils, and can also be transmitted in overcrowded or unhygienic environments through contaminated water, despite its brief survival outside the body.ColonizationOnce ingested, H. pylori enters the stomach and begins colonization by navigating through the mucus layer lining the stomach wall.

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...
