Tension Response at Adherens Junctions

2.9K
The adherens junctions that anchor cells together are multi-protein complexes that dynamically adapt to mechanical stimuli such as tensile forces and shear stress. Mechanosensory proteins in these junctions can sense such mechanical stimuli and undergo a shift in their conformation, resulting in an altered function — a process called mechanotransduction.
α-Catenin as a Mechanosensory Protein
The α-catenin of adherens junctions is an allosteric protein with three VH (vinculin...

mTOR Signaling and Cancer Progression

3.9K
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...

Area of Science:

  • Biomedical Engineering
  • Oncology
  • Cell Biology

Background:

  • Osteosarcoma (OS) is a primary bone cancer common in adolescents.
  • The bone microenvironment significantly influences OS initiation and progression.
  • OS cells convert mechanical signals into biochemical responses, affecting cellular behavior.

Purpose of the Study:

  • To comprehensively review mechanotransduction in OS.
  • To integrate biomechanical cues with epigenetic regulation in OS pathogenesis.
  • To identify therapeutic strategies targeting OS mechanotransduction.

Main Methods:

  • Literature review focusing on mechanotransduction in osteosarcoma.
  • Analysis of aberrant mechanotransduction pathways in OS compared to bone remodeling.
  • Identification of key signaling molecules involved in OS mechanotransduction.

Main Results:

  • Mechanotransduction is significantly altered in osteosarcoma cells.
  • Key signaling molecules mediating these aberrant pathways have been identified.
  • Potential therapeutic targets within these pathways are highlighted.

Conclusions:

  • Understanding aberrant mechanotransduction in OS is crucial for elucidating pathogenesis.
  • Targeting mechanotransduction pathways offers promising therapeutic avenues for osteosarcoma.
  • This review provides a framework for developing novel, targeted OS therapies.
