Insights

Notch inhibitors, used for cancer therapy, can cause skin issues. This study highlights these side effects and their link to skin diseases, improving awareness for better patient care.

Area of Science:

  • Oncology and Dermatology
  • Molecular Biology
  • Translational Medicine

Background:

  • Aberrant Notch signaling is implicated in various cancers, making Notch inhibitors a promising targeted oncological therapy.
  • Notch signaling is crucial for normal skin differentiation and homeostasis; its disruption is linked to dermatological conditions like psoriasis and atopic dermatitis.

Observation:

  • Two cases of cutaneous side effects in patients treated with Notch inhibitors for adenoid cyst carcinoma (ACC) are presented.
  • These side effects suggest a complex interplay between Notch inhibition and skin biology.

Findings:

  • Notch inhibitor treatment can lead to adverse skin reactions, impacting healthy skin homeostasis.
  • The study reviews the role of Notch signaling in skin disease pathogenesis and its connection to treatment side effects.

Implications:

  • Increased awareness of Notch inhibitor-induced cutaneous side effects is crucial for oncologists and dermatologists.
  • Understanding these connections can inform clinical management and potentially lead to strategies to mitigate skin toxicity.
  • This research bridges oncology and dermatology, offering insights into targeted therapy side effects and skin disease mechanisms.

Notch Signaling Pathway03:14

Notch Signaling Pathway

The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not...

Role Of Notch Signalling In Intestinal Stem Cell Renewal01:12

Role Of Notch Signalling In Intestinal Stem Cell Renewal

Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...

Skin Cancer01:30

Skin Cancer

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

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...

Papillary Dermis01:11

Papillary Dermis

Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...
