Summary
The target of rapamycin (TOR) pathway regulates cell growth and its dysregulation is linked to diseases like cancer. Recent research has uncovered new regulatory mechanisms and cellular functions of TOR complexes.
Area of Science:
- Molecular Biology
- Cell Biology
- Biochemistry
Background:
- The target of rapamycin (TOR) is a conserved protein kinase crucial for cell growth regulation.
- TOR functions through two distinct complexes, TORC1 and TORC2.
- Dysregulated TORC1 and TORC2 activity is implicated in diseases such as cancer, diabetes, and neurodegenerative disorders.
Purpose of the Study:
- To review the current understanding of TOR signaling pathways.
- To highlight recent discoveries in TORC1 and TORC2 regulation.
- To discuss the implications of TOR pathway dysregulation in disease.
Main Methods:
- Literature review of recent studies on TOR signaling.
- Analysis of upstream regulators and downstream effectors of TOR.
- Examination of TOR inhibitors and their cellular functions.
Main Results:
- Elucidation of novel regulatory mechanisms for TORC1 and TORC2.
- Identification of previously unrecognized cellular functions of TORC1.
- Summary of the conserved TOR signaling cascade from upstream to downstream.
Conclusions:
- TOR signaling is a fundamental process in cell growth control.
- Understanding TOR regulation is vital for developing therapies for TOR-associated diseases.
- Continued research into TOR pathways promises new therapeutic strategies.

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.

01:22PI3K/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...
01:23Regulation of Expression at Multiple Steps
The gene expression in cells is regulated at different stages: (i) transcription, (ii) RNA processing, (iii) RNA localization, and (iv) translation. Transcriptional regulation is mediated by regulatory proteins such as transcription factors, activators, or repressors—these control gene expression by initiating or inhibiting the transcription of genes. Once a precursor or pre-mRNA is produced, it undergoes post-transcriptional modification, including 5' capping, splicing, and the addition of a...
03:14Notch 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...
