Insights

Aberrant mTOR signaling in the developing brain causes cortical malformations, epilepsy, and neurobehavioral issues. Targeting mTOR offers future therapeutic potential for these developmental disorders.

Area of Science:

  • Neuroscience
  • Molecular Biology
  • Genetics

Background:

  • The mechanistic target of rapamycin (mTOR) signaling pathway is crucial for cerebral cortex development.
  • Loss-of-function mutations in mTOR inhibitor genes (TSC1, TSC2, PTEN, STRADα) lead to mTOR hyperactivation.
  • This hyperactivation is associated with developmental cortical malformations, epilepsy, and neurobehavioral disabilities.

Purpose of the Study:

  • To investigate the role of mTOR signaling in developmental brain disorders.
  • To explore the potential of targeting mTOR for therapeutic interventions.
  • To identify avenues for biomarker assessment, patient stratification, and prognostic measures.

Main Methods:

  • The abstract does not specify methods, focusing on the implications of mTOR signaling.
  • This section would typically detail experimental approaches used to study mTOR signaling in relevant models or patient data.

Main Results:

  • Aberrant mTOR hyperactivation due to specific gene mutations is linked to cortical malformations and associated neurological deficits.
  • Understanding mTOR signaling provides a basis for developing targeted therapies.

Conclusions:

  • Investigating mTOR signaling in developmental brain disorders opens new possibilities for clinical applications.
  • Future research is needed to overcome challenges before widespread clinical therapeutics targeting mTOR can be implemented.

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...
Notch Signaling Pathway03:14

Notch Signaling Pathway

The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not until 1985...

Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
