Insights

The mammalian target of rapamycin (mTOR) pathway interacts with epigenetic modifications, influencing cell growth and potentially impacting cancer and immunosuppression therapies. Understanding this link is crucial for developing new treatments.

Area of Science:

  • Molecular Biology
  • Cell Biology
  • Epigenetics

Background:

  • The mammalian target of rapamycin (mTOR) pathway connects growth factor signaling to protein translation control via PI3K/Akt.
  • mTOR pathway dysregulation is implicated in cell cycle progression and diseases like cancer.
  • Epigenetic modifications, including DNA methylation and histone modification, regulate gene expression and chromatin structure.

Purpose of the Study:

  • To review research on the relationship between the PI3K/Akt/mTOR pathway and epigenetic modifications.
  • To explore how mTOR pathway activation or inhibition influences epigenetic processes.
  • To highlight the therapeutic potential of targeting this interplay in cancer and immunosuppression.

Main Methods:

  • Literature review of scientific research advances.
  • Analysis of studies investigating PI3K/Akt/mTOR signaling.
  • Examination of research on DNA methylation, histone modification, and chromatin remodeling.

Main Results:

  • The PI3K/Akt/mTOR pathway is intricately linked to epigenetic mechanisms.
  • Persistent activation or inhibition of mTOR can alter epigenetic landscapes.
  • Epigenetic modifications play a role in the formation of silenced chromatin.

Conclusions:

  • The interplay between the mTOR pathway and epigenetic modification is a significant area of research.
  • Further investigation is needed to fully elucidate these interactions for therapeutic applications.
  • Targeting the PI3K/Akt/mTOR-epigenetic axis may offer novel therapeutic strategies.

PI3K/mTOR/AKT Signaling Pathway01:22

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...
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.

Epigenetic Regulation01:37

Epigenetic Regulation

Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.
