Insights

Epidermal growth factor receptor inhibitors (EGFRIs) offer targeted cancer therapy with fewer systemic side effects. However, prolonged use can cause unique skin toxicities, including eyelash trichomegaly, requiring specific management strategies.

Area of Science:

  • Oncology
  • Dermatology
  • Pharmacology

Background:

  • Targeted therapies like epidermal growth factor receptor inhibitors (EGFRIs) have revolutionized cancer treatment by inhibiting oncogenic pathways.
  • EGFRIs offer improved tolerability and reduced systemic adverse effects compared to traditional chemotherapy.

Observation:

  • EGFRIs commonly cause toxicities affecting the skin and adnexal structures in a majority of patients.
  • Trichomegaly of the eyelashes is a distinctive side effect observed with prolonged EGFRI treatment.

Findings:

  • Understanding the mechanisms of oncogenesis has enabled the development of targeted therapies.
  • EGFRIs, while effective, present unique dermatological side effects like eyelash changes.

Implications:

  • Familiarity with EGFRI-induced trichomegaly is crucial for effective patient management.
  • Knowledge of potential complications and treatment strategies for this unique side effect is essential for clinicians.

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...

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...

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:

Accessory Structures of the Skin: Hair Growth and Types01:20

Accessory Structures of the Skin: Hair Growth and Types

Hair growth begins with the production of keratinocytes by the basal cells of the hair bulb. As new cells are deposited at the hair bulb, the hair shaft is pushed through the follicle toward the surface. Keratinization is completed as the cells are pushed to the skin surface to form the shaft of hair that is externally visible. The external hair is completely dead and composed entirely of keratin. Hair can be cut or shaven without damaging the hair structure because the cut is superficial. Most...

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...
