Insights

The PI3K pathway is crucial in brain cancers like gliomas. Understanding PI3K

Area of Science:

  • Oncology
  • Molecular Biology
  • Cancer Signaling

Background:

  • The phosphoinositide 3-kinase (PI3K) pathway is frequently dysregulated in human cancers, particularly gliomas.
  • Aberrant PI3K signaling, driven by mutations or altered inhibitors, promotes cancer cell survival, proliferation, migration, and differentiation.
  • The specific transcription factors regulated by PI3K in tumor cells are not fully understood.

Purpose of the Study:

  • To review the role of PI3K signaling-regulated transcription in brain cancer cells.
  • To highlight recent investigations into PI3K-mediated transcriptional regulation in gliomas.
  • To explore the therapeutic potential of targeting PI3K pathway components in brain tumors.

Main Methods:

  • Literature review of recent investigations.
  • Analysis of PI3K-responsive signaling factors and their downstream transcription factors.
  • Focus on gene expression networks regulated by PI3K in brain cancer.

Main Results:

  • PI3K signaling influences numerous transcription factors via intermediate kinases.
  • These transcription factors control gene expression networks essential for cancer cell phenotypes.
  • Recent studies provide insights into PI3K-regulated transcription in gliomas.

Conclusions:

  • Targeting PI3K signaling-regulated transcription offers a promising avenue for brain cancer therapy.
  • Developing sophisticated anti-cancer strategies may involve targeting both upstream and downstream PI3K pathway components.
  • Further understanding of PI3K-mediated transcriptional control can lead to novel therapeutic approaches.

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 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.
The mTOR pathway or the...

Targeted Cancer Therapies02:57

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...

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...

Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...
