Abstract

Insights

The epidermal growth factor receptor 4 (ErbB4) exhibits tumor suppressor properties, inhibiting cancer growth. This review explores ErbB4

Area of Science:

  • Oncology
  • Molecular Biology
  • Cell Signaling

Background:

  • The epidermal growth factor receptor (EGFR) family includes ErbB1-4, crucial in tumor development.
  • ErbB4 uniquely possesses tumor-suppressive, growth-inhibiting properties.
  • ErbB4 is vital in normal development of the heart, nervous, and mammary systems.

Purpose of the Study:

  • To review the multifaceted role of ErbB4 in various cancers.
  • To clarify conflicting data regarding ErbB4's function in tumorigenesis.
  • To highlight ErbB4's significance beyond oncology, including cardiovascular disease.

Main Methods:

  • Literature review of existing studies on ErbB4.
  • Analysis of ErbB4's function in normal physiology.
  • Examination of ErbB4's role in diverse tumor types.

Main Results:

  • ErbB4 generally acts as a tumor suppressor.
  • Evidence suggests ErbB4 involvement in breast, lung, and brain cancers, among others.
  • Conflicting reports necessitate further investigation into ErbB4's complex roles.

Conclusions:

  • ErbB4 plays a significant role in normal tissue development and cancer.
  • Understanding ErbB4 is critical for treating various cancers.
  • ErbB4's role extends to other conditions like cardiovascular disease.

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...

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...

The Retinoblastoma Gene01:20

The Retinoblastoma Gene

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal

Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.

Negative Regulator Molecules

Positive regulators allow a cell to advance through cell cycle checkpoints. Negative regulators have an equally important role as they terminate a cell’s progression through the cell cycle—or pause it—until the cell meets specific criteria.

Inhibition of Cdk Activity02:34

Inhibition of Cdk Activity

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...
