Insights

Low oxygen (hypoxia) impacts the mammalian target of rapamycin complex 1 (mTORC1) pathway, a key stress regulator. This review explores how hypoxia dysregulates mTORC1 signaling in pediatric solid tumors.

Area of Science:

  • Cellular Biology
  • Oncology
  • Biochemistry

Background:

  • Tissue homeostasis relies on integrating cellular and extracellular signals.
  • The mammalian target of rapamycin (mTOR) pathway is crucial for stress response regulation.
  • Enhanced mTOR complex 1 (mTORC1) signaling is observed in many cancers, even under stress.

Purpose of the Study:

  • To review emerging details on how hypoxia regulates mTORC1 signaling.
  • To explore the consequences of hypoxia-induced mTORC1 dysregulation in pediatric solid tumors.

Main Methods:

  • Literature review of studies on hypoxia and mTORC1 signaling.
  • Analysis of mTORC1 pathway regulation under low oxygen conditions.
  • Examination of pediatric solid tumor data related to mTORC1 dysregulation.

Main Results:

  • Hypoxia significantly impacts mTORC1 signaling pathways.
  • Dysregulated mTORC1 signaling due to hypoxia is implicated in pediatric solid tumor development.
  • Specific mechanisms linking hypoxia to mTORC1 activation in cancer are being elucidated.

Conclusions:

  • Understanding hypoxia's role in mTORC1 regulation is vital for pediatric cancer research.
  • Targeting the hypoxia-mTORC1 axis may offer new therapeutic strategies for pediatric solid tumors.
  • Further research is needed to fully elucidate these complex interactions.

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.

PI3K/mTOR/AKT Signaling Pathway

The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a rapamycin-insensitive companion...
Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl hydroxylase and factor...
Regulation of the Unfolded Protein Response01:31

Regulation of the Unfolded Protein Response

Inositol-requiring kinase one or IRE1 is the most conserved eukaryotic unfolded protein response (UPR) receptor. It is a type I transmembrane protein kinase receptor with a distinctive site-specific RNase activity. As the binding mechanics of the misfolded proteins with the N-terminal domain of IRE-1 are unclear, three binding models — direct, indirect, and allosteric -- are proposed for receptor activation. Nevertheless, it is known that once a misfolded protein associates with IRE1, it...
Adaptive Mechanisms in Cancer Cells02:53

Adaptive Mechanisms in Cancer Cells

Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...
