Insights

The mammalian target of rapamycin (mTOR) pathway is implicated in cancer. Inhibitors like rapamycin and rapalogs show promise in treating certain cancers by affecting tumor growth.

Area of Science:

  • Oncology
  • Molecular Biology
  • Pharmacology

Background:

  • The mammalian target of rapamycin (mTOR) pathway plays a crucial role in cell growth and proliferation.
  • Aberrant mTOR signaling, through overexpression or mutation of key proteins, is frequently observed in various cancers.

Purpose of the Study:

  • To review preclinical and clinical data on the function of mTOR in cancer.
  • To summarize recent discoveries regarding mTOR's role in tumor growth regulation.

Main Methods:

  • Review of preclinical studies investigating mTOR inhibitors in cancer cell lines and tumor models.
  • Analysis of clinical trial data evaluating the efficacy of rapamycin analogs (rapalogs) in cancer patients.

Main Results:

  • Rapamycin and rapalogs demonstrate in vitro and in vivo inhibition of cancer cell growth.
  • Clinical trials suggest potential therapeutic benefits of rapalogs for specific cancer subsets.

Conclusions:

  • Understanding mTOR regulation dynamics and its role in the tumor microenvironment is key to interpreting clinical responses.
  • mTOR inhibitors represent a promising therapeutic strategy for subsets of cancers, warranting further investigation.

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.

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against specific...

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...

Cancer Therapies

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
