Insights

Non-small cell lung cancer (NSCLC) has a poor prognosis. Targeting the PI3K/Akt/mTOR pathway, crucial for cell survival and proliferation, offers potential new therapies for NSCLC.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cell Signaling

Background:

  • Non-small cell lung cancer (NSCLC) is a leading cause of cancer mortality worldwide, with limited treatment options and a low 5-year survival rate.
  • NSCLC is often diagnosed at advanced stages, making surgical intervention impractical, and conventional therapies like chemotherapy and radiotherapy show inadequate efficacy.

Purpose of the Study:

  • To review recent advancements in understanding the PI3K/Akt/mTOR signaling pathway's role in NSCLC.
  • To explore the pathway's components, its involvement in anti-apoptosis and pro-proliferation mechanisms in NSCLC.
  • To discuss potential therapeutic targets within the PI3K/Akt/mTOR pathway for NSCLC treatment.

Main Methods:

  • Literature review of recent scientific publications.
  • Analysis of the PI3K/Akt/mTOR signaling pathway's molecular composition.
  • Examination of the pathway's influence on apoptosis and cell proliferation in NSCLC.

Main Results:

  • The PI3K/Akt/mTOR pathway is a critical intracellular signaling cascade implicated in NSCLC development and progression.
  • This pathway regulates key cellular processes including apoptosis and proliferation, contributing to tumor growth.
  • Specific components and mechanisms within the pathway present viable targets for novel NSCLC therapies.

Conclusions:

  • The PI3K/Akt/mTOR signaling pathway is a significant factor in NSCLC pathogenesis.
  • Targeting this pathway holds promise for developing more effective therapeutic strategies against NSCLC.
  • Further research into PI3K/Akt/mTOR pathway inhibitors could improve outcomes for NSCLC patients.

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 Progression03:03

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...
Non-Canonical Wnt Signaling Pathways01:41

Non-Canonical Wnt Signaling Pathways

Wnt is a zygotic effect gene that is expressed during very early embryonic development. It regulates various processes in animals starting from early development through the adult stage, such as organogenesis in the embryo and maintenance of neuronal and blood stem cells. Wnt proteins can induce a wide variety of intracellular pathways depending upon the specific abilities of different Wnt ligands to form a complex with shared and cognate receptors in the presence of different co-receptors. The...
