Abstract

Insights

Breast cancer, a leading cause of cancer death in women, involves the PI3K/mTOR pathway. Inhibitors targeting this pathway show promise for new breast cancer treatments.

Area of Science:

  • Oncology
  • Molecular Biology

Background:

  • Breast cancer is a major cause of cancer-related deaths in women globally.
  • Early detection and treatment remain critical challenges.
  • The phosphoinositide 3 kinase (PI3K)/Akt/mammalian target of rapamycin (mTOR) signaling pathway is frequently activated in breast cancers, driving cell growth and tumor development.

Purpose of the Study:

  • To review the role of the PI3K/mTOR pathway in breast cancer.
  • To explore inhibitors of the PI3K/mTOR pathway as potential therapeutic agents.
  • To provide insights into the structure and regulation of mTOR.

Main Methods:

  • Literature review of preclinical and clinical trials.
  • Analysis of studies on targeted therapies for breast cancer.
  • Examination of the PI3K/mTOR pathway and its inhibitors.

Main Results:

  • The PI3K/mTOR pathway is implicated in breast cancer cell growth and tumor development.
  • Inhibitors of the PI3K/mTOR pathway, including first and second-generation agents, are being investigated.
  • These inhibitors may be effective alone or in combination with other therapies.

Conclusions:

  • Targeted therapies, particularly those inhibiting the PI3K/mTOR pathway, offer potential for improved breast cancer treatment.
  • Understanding mTOR's precise role and its inhibitors is crucial for developing effective endocrine therapies.

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...

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...

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...

The Intrinsic Apoptotic Pathway01:31

The Intrinsic Apoptotic Pathway

Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...
