Abstract

Insights

TNF-related apoptosis-inducing ligand (TRAIL) therapies show promise for targeted cancer treatment by inducing apoptosis. Combination strategies can overcome TRAIL resistance, enhancing therapeutic potential.

Area of Science:

  • Oncology
  • Molecular Biology
  • Immunology

Background:

  • TNF-related apoptosis-inducing ligand (TRAIL) induces apoptosis in tumor cells via TRAIL-R1/R2, with low normal cell toxicity.
  • Development focuses on receptor-specific TRAIL variants and agonistic antibodies to activate death-receptor pathways, avoiding decoy receptor interference.
  • TRAIL-based therapies are advancing in clinical trials for cancer treatment.

Purpose of the Study:

  • To review recent advances in TRAIL-based cancer therapies, including receptor-specific variants and agonistic antibodies.
  • To discuss combination therapies aimed at overcoming TRAIL resistance in cancer cells.
  • To provide insights into current clinical trials and future prospects of TRAIL signaling pathway-targeting therapies.

Main Methods:

  • Review of recent advancements in TRAIL and agonistic antibody development for cancer therapy.
  • Discussion of combination strategies to enhance TRAIL efficacy and overcome resistance.
  • Analysis of data from ongoing clinical trials involving TRAIL-targeting agents.

Main Results:

  • Several TRAIL variants and agonistic antibodies targeting TRAIL-R1/R2 are in clinical trials.
  • Combination therapies involving TRAIL or antibodies with chemotherapy, targeted agents, or irradiation can sensitize resistant tumors.
  • Understanding of TRAIL signaling pathways is crucial for overcoming therapeutic obstacles.

Conclusions:

  • Targeting the TRAIL/TRAIL receptor pathway offers a promising strategy for molecularly targeted, pro-apoptotic cancer therapy.
  • Further research and clinical trials are essential to fully realize the potential of TRAIL-based treatments.
  • Combination approaches are key to overcoming resistance and improving outcomes in TRAIL-targeted cancer therapy.

Receptor Tyrosine Kinases01:26

Receptor Tyrosine Kinases

Receptor tyrosine kinases or RTKs are membrane-bound receptors that phosphorylate specific tyrosine on protein substrates. RTKs regulate cellular growth, differentiation, survival, and migration. They contain an extracellular ligand binding domain, a transmembrane domain, and a cytosolic tail with intrinsic kinase activity. Several extracellular signaling molecules activate RTKs in one or more ways and relay the signal downstream. Ligands such as platelet-derived growth factor (PDGF) or...

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:
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...
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...
Amplifying Signals via Enzymatic Cascade01:22

Amplifying Signals via Enzymatic Cascade

When a ligand binds to a cell-surface receptor, the receptor's intracellular domain changes shape, which may either activate its enzyme function or allow its binding to other molecules. The initial signal is amplified by most signal transduction pathways. This means that a single ligand molecule can activate multiple molecules of a downstream target. Proteins that relay a signal are most commonly phosphorylated at one or more sites, activating or inactivating the protein. Kinases catalyze the...
The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as  SH2...
