Insights

Dependence receptors (DRs) trigger cell survival pathways with ligands but induce apoptosis without them. This highlights DRs

Area of Science:

  • Molecular Biology
  • Cell Biology
  • Cancer Research

Background:

  • Dependence receptors (DRs) are a family of membrane receptors characterized by a unique dual signaling capacity.
  • These receptors activate pro-survival pathways in the presence of their ligand and initiate apoptosis in its absence.
  • Cells expressing DRs are critically dependent on extracellular ligand availability for survival.

Purpose of the Study:

  • To review the molecular mechanisms governing Dependence Receptor (DR) signaling.
  • To explore the role of DRs in developmental processes.
  • To discuss the implications of DR deregulation in tumorigenesis and their potential as cancer therapeutic targets.

Main Methods:

  • Literature review of existing data on Dependence Receptors (DRs).
  • Analysis of molecular mechanisms, developmental roles, and involvement in cancer.
  • Evaluation of DRs as potential therapeutic targets.

Main Results:

  • DRs exhibit context-dependent signaling, activating survival or apoptotic pathways based on ligand presence.
  • DRs play significant roles during development.
  • Dysregulation of DRs is implicated in various cancers, presenting them as novel therapeutic targets.

Conclusions:

  • Dependence receptors (DRs) are crucial regulators of cell fate, linking ligand availability to survival or apoptosis.
  • Understanding DRs' molecular mechanisms and roles in development and cancer is vital.
  • DRs represent promising targets for future cancer therapies.

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...

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:
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...
Cell Signaling in Plants01:25

Cell Signaling in Plants

Plant cells communicate to coordinate their cycle of growth, flowering and fruiting, and activities in roots, shoots, and leaves in response to the changing environmental conditions. Plant signaling is distinct from animal signaling. Plants primarily utilize enzyme-linked receptors, whereas the largest class of cell-surface receptors in animals are G-protein coupled receptors (GPCRs). Unlike animals, receptor tyrosine kinases are rare in plants. Instead, plants have a diverse class of...
Types of Receptors: Cell Surface Receptors01:28

Types of Receptors: Cell Surface Receptors

Cell-surface receptors, also known as transmembrane receptors, are cell surface, membrane-anchored (integral) proteins that bind to external ligand molecules. This type of receptor spans the plasma membrane and performs signal transduction, converting an extracellular signal into an intracellular signal. Ligands that interact with cell-surface receptors do not have to enter the cell that they affect. Cell-surface receptors are also called cell-specific proteins or markers because they are...
Signal Transduction: Overview01:26

Signal Transduction: Overview

Cells respond to many types of information, often through receptor proteins positioned on the membrane. They respond to chemical signals, such as hormones, neurotransmitters, and other signaling molecules, initiating a series of molecular reactions to produce an appropriate response. This is called signal transduction. Cells also coordinate different responses elicited by the same signaling molecule via mediators, allowing molecular cross-talk.
Typically, signal transduction involves three...
