Summary
This retrospective celebrates 25 years of target of rapamycin (TOR) discovery. It highlights TOR
Area of Science:
- Cell Biology
- Molecular Biology
- Biochemistry
Background:
- The target of rapamycin (TOR) pathway is a crucial regulator of cell growth.
- TOR's central role in controlling cellular processes is well-established.
- This year commemorates the 25th anniversary of TOR discovery.
Purpose of the Study:
- To provide a retrospective on the discovery of the target of rapamycin (TOR) kinase.
- To elucidate the cellular functions of TOR.
- To emphasize the seminal 1996 findings linking TOR to nutrient-responsive cell growth.
Main Methods:
- Literature review and historical analysis of key publications.
- Focus on the 1996 study by Barbet et al. detailing TOR's role in nutrient sensing.
- Retrospective analysis of the elucidation of TOR's cellular functions.
Main Results:
- TOR was discovered 25 years ago as a highly conserved kinase.
- Subsequent research elucidated TOR's central role in controlling cell growth.
- The 1996 study provided the first evidence for TOR mediating nutrient-dependent growth control.
Conclusions:
- The discovery of TOR has been pivotal in understanding cell growth regulation.
- TOR's role in sensing nutrients and controlling cell growth remains a key area of research.
- Continued study of TOR pathways is essential for advancing cell biology and medicine.

mTOR Signaling and Cancer Progression
5.0K
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
6.1K
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...

Mitogens and the Cell Cycle
8.3K
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...

Cells Coordinate Growth and Proliferation
5.2K
Cell size is a significant factor impacting cellular design, function, and fitness. There exists some internal coordination by which cells double their masses before division, thus, achieving homeostasis. Coordination between cell growth and proliferation depends on the checkpoints in between cell cycle phases. Loss of coordination or failure in the checkpoint mechanism can drive the cell to uncontrolled growth and loss of cellular function. Like dividing cells that coordinate cellular growth,...
