Insights

The phosphatidyl inositol 3-kinase (PI3K)/Akt pathway is frequently altered in breast cancer (BC), driving tumor growth. Understanding PI3K/Akt signaling is crucial for developing targeted BC therapies.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cell Signaling

Background:

  • The phosphatidyl inositol 3-kinase (PI3K)/Akt pathway regulates critical cellular functions like growth, proliferation, and survival.
  • Alterations in PI3K/Akt pathway components can lead to cellular transformation and are frequently observed in breast cancer (BC).

Purpose of the Study:

  • To review experimental evidence on the contribution of PI3K/Akt pathway alterations in human breast cancer.
  • To provide an updated overview of the effects of modulating this pathway in breast cancer treatment.

Main Methods:

  • Literature review of experimental studies.
  • Analysis of signaling pathway alterations and their impact on breast cancer.

Main Results:

  • The PI3K/Akt pathway is a significant mediator in various cellular processes relevant to tumorigenesis.
  • Dysregulation of this pathway is common in breast cancer, highlighting its role in the pathology.

Conclusions:

  • A comprehensive understanding of PI3K/Akt signaling intricacies is essential for clinical applications in breast cancer.
  • Targeting the PI3K/Akt pathway holds potential for novel therapeutic strategies in breast cancer management.

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...

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.

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...
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...
IP3/DAG Signaling Pathway01:11

IP3/DAG Signaling Pathway

Membrane lipids such as phosphatidylinositol (PI) are precursors for several membrane-bound and soluble second messengers. Specific kinases phosphorylate PI and produce phosphorylated inositol phospholipids. One such inositol phospholipids are the  phosphatidylinositol-4,5 bisphosphate [PI(4,5)P2], present in the inner half of the lipid bilayer. Upon ligand binding, GPCR stimulates Gq proteins to turn on phospholipase Cꞵ. Activated phospholipase Cꞵ cleaves PI(4,5)P2 and produces two-second...
