Insights

Drug-induced acne, a known dermatological issue, can be triggered by epidermal growth factor receptor inhibitors used in cancer therapy. Understanding the mechanism aids in targeted dermatological treatments for these adverse effects.

Area of Science:

  • Dermatology
  • Oncology
  • Pharmacology

Background:

  • Paroxysmal drug-induced acne is a recognized dermatological condition.
  • Various medications can trigger this acneiform eruption.
  • Epidermal growth factor receptor (EGFR) inhibitors, used in cancer treatment, are increasingly associated with this side effect.

Purpose of the Study:

  • To review the occurrence and pathogenic mechanisms of drug-induced acne.
  • To highlight the role of anti-EGFR drugs in causing acneiform eruptions.
  • To discuss the dermatological management of these adverse events.

Main Methods:

  • Literature review of drug-induced acne, focusing on EGFR inhibitors.
  • Analysis of the proposed pathogenic mechanisms involving epidermal growth factor (EGF).
  • Summary of reported cutaneous side effects associated with anti-EGFR therapy.

Main Results:

  • Anti-EGFR drugs can induce acneiform eruptions, paronychia, and xerosis.
  • The mechanism involves EGF's role in microcomedo rupture and subsequent inflammation.
  • These drug-induced skin conditions require specific dermatological interventions.

Conclusions:

  • Drug-induced acne, particularly from anti-EGFR agents, is a significant adverse effect in oncology.
  • The pathogenesis is linked to EGF pathway dysregulation.
  • Targeted dermatological treatments are essential for managing these side effects.

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...
Acne Infection01:27

Acne Infection

Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...

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:
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...
Receptor Tyrosine Kinases01:26

Receptor Tyrosine Kinases

Receptor tyrosine kinases or RTKs are membrane-bound receptors that phosphorylate specific tyrosine on protein substrates. RTKs regulate cellular growth, differentiation, survival, and migration. They contain an extracellular ligand binding domain, a transmembrane domain, and a cytosolic tail with intrinsic kinase activity. Several extracellular signaling molecules activate RTKs in one or more ways and relay the signal downstream. Ligands such as platelet-derived growth factor (PDGF) or...
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 specific...
