Insights

The phosphatidyl inositol 3-kinase (PI3K)/Akt pathway regulates cell growth and survival. Its dysregulation is common in cancer, making it a therapeutic target, but more research is needed for effective drug development.

Area of Science:

  • Molecular Biology
  • Cellular Signaling
  • Oncology

Background:

  • The phosphatidyl inositol 3-kinase (PI3K)/Akt pathway is crucial for cellular processes like growth, proliferation, and survival.
  • Dysregulation of this pathway, via oncogene activation or tumor suppressor inactivation, contributes to cellular transformation and cancer development.

Purpose of the Study:

  • To review experimental findings on key molecules within the PI3K/Akt signaling network.
  • To explore the significance of these molecules in human breast cancer.

Main Methods:

  • Review of experimental studies focusing on PI3K, PTEN, ILK, and Akt.
  • Analysis of the role of these components in cancer signaling.

Main Results:

  • The PI3K/Akt pathway is frequently altered in human cancers.
  • Specific components like PI3K, PTEN, ILK, and Akt play significant roles in cancer progression.

Conclusions:

  • Understanding the intricacies of the PI3K/Akt pathway is essential for developing targeted cancer therapies.
  • Further research is needed to translate this knowledge into effective pharmacological agents for breast cancer treatment.

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.

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...
Phosphoinositides and PIPs01:42

Phosphoinositides and PIPs

Phosphoinositides are a group of phospholipids containing a glycerol backbone with two fatty acid chains and a phosphate attached to a myoinositol sugar ring. The inositol head group extends into the cytoplasm, where it is modified by adding phosphate groups to form phosphatidylinositol phosphates or PIPs.
Different phosphoinositides are synthesized and recruited on the cytosolic face of the plasma membrane. The localization of specific phosphoinositides concentrated in separate membrane...
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...
