Insights

Epidermal growth factor receptor (EGFR) inhibitors, used for cancer, show promise for treating Alzheimer's disease (AD). These drugs may reduce amyloid-beta pathology and improve cognition in AD mouse models.

Area of Science:

  • Neuroscience
  • Oncology
  • Pharmacology

Background:

  • Alzheimer's disease (AD) lacks effective treatments, prompting research into drug repurposing.
  • Epidermal growth factor receptor (EGFR) inhibitors, established anti-cancer drugs, are emerging as potential AD therapeutics.
  • EGFR plays roles in both cancer and neurodegenerative processes relevant to AD.

Purpose of the Study:

  • To review the dual functions of EGFR in cancer and Alzheimer's disease.
  • To evaluate the potential of EGFR as a molecular target for AD therapy.
  • To discuss the therapeutic prospects of anti-cancer EGFR tyrosine kinase inhibitors (TKIs) for AD.

Main Methods:

  • Literature review of studies on EGFR function in cancer and AD.
  • Analysis of research on EGFR inhibitors in AD mouse models.
  • Synthesis of findings on the effects of EGFR TKIs on AD pathology and cognition.

Main Results:

  • EGFR inhibitors approved for cancer treatment demonstrate potential for AD therapy.
  • Studies in AD mouse models indicate EGFR inhibitors can reduce amyloid-beta pathology.
  • EGFR inhibitors have shown to improve cognitive function in AD models.

Conclusions:

  • EGFR is a significant molecular target for both cancer and Alzheimer's disease.
  • EGFR tyrosine kinase inhibitors (TKIs) represent a promising therapeutic strategy for AD.
  • Repurposing anti-cancer EGFR inhibitors offers a viable avenue for novel AD treatments.

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...

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...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

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...

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:
