Insights

The phosphatidylinositol 3-kinase (PI3K)/Akt/mammalian target of rapamycin (mTOR) pathway drives gastric carcinoma growth and metastasis. Understanding this pathway is crucial for developing new targeted therapies for gastric cancer.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cell Signaling

Background:

  • The phosphatidylinositol 3-kinase (PI3K)/Akt/mammalian target of rapamycin (mTOR) pathway is frequently altered in gastric carcinoma.
  • This pathway regulates critical cellular processes including growth, metabolism, survival, and metastasis.

Purpose of the Study:

  • To review current knowledge on the role of the PI3K/Akt/mTOR pathway in gastric carcinoma pathogenesis.
  • To identify potential therapeutic targets within this pathway for gastric cancer treatment.

Main Methods:

  • Literature review of studies on PI3K/Akt/mTOR signaling in gastric carcinoma.
  • Analysis of genetic alterations and therapeutic strategies targeting this pathway.

Main Results:

  • The PI3K/Akt/mTOR pathway is a significant promoter of gastric cancer progression and chemoresistance.
  • Despite its importance, PI3K/Akt/mTOR inhibitors are not yet approved for gastric carcinoma treatment, except for ErbB2-targeting agents.

Conclusions:

  • Further understanding of PI3K/Akt/mTOR signaling in gastric carcinoma is essential for elucidating tumor development mechanisms.
  • Identifying optimal therapeutic targets within this pathway holds promise for future gastric cancer therapies.

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...

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.

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...

Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as  SH2...
