Summary
The PI3K/AKT/mTOR pathway regulates cell growth. Rapamycin analogs like temsirolimus show promise in cancer therapy, with ongoing trials exploring their use in various tumors.
Area of Science:
- Oncology
- Molecular Biology
- Pharmacology
Background:
- The PI3K/AKT/mTOR pathway is crucial for cell growth, proliferation, survival, and angiogenesis.
- Mutations in this pathway can lead to cancer development.
- Rapamycin and its analogs are mTOR inhibitors with demonstrated anti-tumor activity.
Purpose of the Study:
- To review the role of the PI3K/AKT/mTOR pathway in cancer.
- To discuss the therapeutic potential of rapamycin analogs in oncology.
- To highlight ongoing clinical trials and future research directions.
Main Methods:
- Literature review of PI3K/AKT/mTOR pathway signaling.
- Analysis of preclinical and clinical data for rapamycin analogs (temsirolimus, everolimus, deforolimus).
- Review of ongoing clinical trials in various cancer types.
Main Results:
- Rapamycin analogs have shown anti-tumor activity in renal cancer and mantle cell lymphoma.
- Clinical trials are evaluating these agents in multiple other tumor types.

01:22PI3K/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...
03:03mTOR 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.

01:20The 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...
01:19Interactions 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...

01:33Cancer-Critical Genes I: Proto-oncogenes
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
