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.

Area of Science:

  • Mathematical biology
  • Computational oncology
  • Biophysics

Background:

  • Avascular tumor growth is a complex process influenced by cellular and biochemical factors.
  • Understanding tumor cell cycle, signaling, and mechanics is crucial for effective treatment.
  • The role of glucose transporter GLUT1 in tumor progression requires further investigation.

Purpose of the Study:

  • To develop a multiscale mathematical model for avascular tumor growth.
  • To investigate the influence of the biochemical environment and cellular energetics on tumor development.
  • To analyze the role of glucose transporter GLUT1 in tumor cell mitosis and disease progression.

Main Methods:

  • A multiscale mathematical model incorporating cellular and biochemical aspects of tumor growth.
  • A 'health function' to represent cellular biochemical energy relative to extracellular matrix (ECM) carrying capacity and metabolic processes.
  • Investigation of glucose transporter GLUT1's role in mitosis across different tumor cell populations.

Main Results:

  • Simulations were performed to scale up and estimate the evolution of tumor cell populations.
  • The model successfully integrated biochemical processes into multiscale tumor growth analysis.
  • Overexpression of GLUT1 in malignant cells was linked to disease development.

Conclusions:

  • The developed multiscale model provides a framework for understanding avascular tumor growth.
  • Incorporating biochemical processes enhances the assessment of targeted therapeutic strategies.
  • The model offers insights into the significance of GLUT1 in tumor cell proliferation and disease progression.
