Insights

Squamous cell carcinoma (SCC) is a growing skin cancer concern. Targeted therapies blocking epidermal growth factor receptor (EGFR) offer a key non-surgical treatment for advanced cases.

Area of Science:

  • Dermatology
  • Oncology
  • Molecular Biology

Background:

  • Squamous cell carcinoma (SCC) is a prevalent skin cancer with significant morbidity.
  • Advanced SCC can be metastatic and treatment-resistant.
  • Epidermal growth factor receptor (EGFR) inhibitors are crucial non-surgical options for advanced SCC.

Purpose of the Study:

  • To describe the role of EGFR in skin cancer.
  • To summarize outcomes of anti-EGFR targeted therapies.
  • To discuss the future of anti-EGFR therapies in skin cancer treatment.

Main Methods:

  • Literature review of published outcomes for anti-EGFR therapies.
  • Analysis of EGFR's role in skin carcinogenesis.
  • Discussion of current and future therapeutic strategies.

Main Results:

  • EGFR plays a significant role in skin cancer development.
  • Targeted anti-EGFR therapies show promise for advanced SCC.
  • Understanding the evidence and side effect profiles is essential.

Conclusions:

  • Anti-EGFR therapies represent a significant advancement in treating advanced skin SCC.
  • Informed patient advice requires knowledge of treatment efficacy and adverse effects.
  • Targeted molecular therapies are increasingly important in oncology.

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...
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...

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:
Pharmacogenetics of Drug Targets: β₂-Adrenergic Receptors, Apo E, Thymidylate Synthase01:11

Pharmacogenetics of Drug Targets: β₂-Adrenergic Receptors, Apo E, Thymidylate Synthase

Genetic polymorphisms in drug targets have emerged as critical determinants of interindividual variability in drug response and toxicity. Pharmacogenomic investigations increasingly focus on identifying these variations to personalize and optimize therapeutic interventions. A drug target may be a receptor, enzyme, or signaling protein involved in pharmacologic responses or disease-related pathways. While early pharmacogenetic studies focused primarily on drug metabolism, current research...
Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
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...
