Insights

Environmental agents can disrupt the epidermal growth factor receptor (EGFR) pathway, influencing cell behavior and potentially leading to cancer. This review explores how these disruptions contribute to cellular stress and carcinogenesis.

Area of Science:

  • Molecular Biology
  • Cell Biology
  • Environmental Health

Background:

  • Epidermal growth factor receptor (EGFR) is a key protein tyrosine kinase receptor involved in crucial cellular processes like proliferation, survival, and apoptosis.
  • Aberrant EGFR signaling is strongly linked to the initiation and progression of various cancers.
  • Environmental factors can significantly impact EGFR function and signaling pathways.

Purpose of the Study:

  • To review recent advancements in understanding how environmental agents affect EGFR signaling.
  • To elucidate the epigenetic mechanisms underlying cellular stress and carcinogenesis induced by environmental exposures.
  • To provide a comprehensive overview of EGFR's role in environmental carcinogenesis.

Main Methods:

  • Literature review of recent scientific publications.
  • Analysis of studies investigating environmental agents' effects on EGFR.
  • Synthesis of data on EGFR phosphorylation, conformation, function, and membrane distribution.

Main Results:

  • Environmental physical and chemical agents can interfere with EGFR signaling through various mechanisms.
  • These interferences affect EGFR phosphorylation, conformation, function, and cellular localization.
  • Altered EGFR signaling by environmental agents can lead to changes in gene expression and cell fate, promoting carcinogenesis.

Conclusions:

  • Understanding the interplay between environmental agents and EGFR signaling is crucial for comprehending carcinogenesis.
  • Epigenetic modifications induced by environmental factors play a significant role in EGFR-related cancers.
  • Further research into these mechanisms can inform strategies for cancer prevention and treatment.

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...
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 activation may...
Clinical Applications of Epidermal Stem Cells01:19

Clinical Applications of Epidermal Stem Cells

Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own EpiSCs...
Enzyme-linked Receptors01:00

Enzyme-linked Receptors

Enzyme-linked receptors are proteins that act as both receptor and enzyme, activating multiple intracellular signals. This is a large group of receptors that include the receptor tyrosine kinase (RTK) family. Many growth factors and hormones bind to and activate the RTKs.
Neurotrophin (NT) receptors are a family of RTKs, including trkA, trkB, and trkC (tropomyosin-related kinase) receptors. TrkA is specific for nerve growth factor (NGF), neurotrophin-6, and neurotrophin-7. TrkB binds...

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.
