Insights

Epidermal growth factor receptor (EGFR) inhibitors offer targeted cancer treatment but can cause skin toxicities due to EGFR signalling in the skin. Understanding these side effects is crucial for patient quality of life and consistent cancer therapy.

Area of Science:

  • Oncology
  • Dermatology
  • Pharmacology

Background:

  • Epidermal growth factor receptor (EGFR) inhibitors (EGFRIs) demonstrate increased target specificity, reducing some side effects.
  • However, inhibiting EGFR signalling in essential tissues leads to adverse events.
  • Dermatological toxicities are common with EGFRIs due to EGFR's role in skin.

Purpose of the Study:

  • To highlight the need for better understanding of EGFR inhibitor-induced dermatological toxicities.
  • To emphasize the impact of these toxicities on patient well-being and treatment adherence.
  • To advocate for improved management strategies for EGFRI-related skin side effects.

Main Methods:

  • Review of existing literature on EGFRIs and their dermatological side effects.
  • Analysis of the role of EGFR signalling in skin physiology.
  • Discussion of the clinical implications of EGFRI-induced skin toxicities.

Main Results:

  • EGFRIs can cause significant physical and psycho-social discomfort.
  • These toxicities may necessitate interruption or dose modification of anticancer treatments.
  • Current understanding of these toxicities requires enhancement for effective management.

Conclusions:

  • Improved understanding of EGFRI-related dermatological toxicities is urgently needed.
  • Development of adequate staging systems and mechanistically driven therapies is essential.
  • Addressing these toxicities is key to ensuring patient quality of life and consistent antineoplastic therapy.

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...

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...

Transducer Mechanism: Enzyme-Linked Receptors

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:

DNA Distortion and Damage
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...

Allergic Drug Reactions01:27

Allergic Drug Reactions

Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing...
