Insights

The phosphoinositide 3-kinase (PI3K) pathway is crucial for cell growth and survival. Understanding its role in cancer is key to developing targeted therapies and overcoming drug resistance.

Area of Science:

  • Oncology
  • Molecular Biology
  • Biochemistry

Background:

  • The phosphoinositide 3-kinase (PI3K) pathway regulates fundamental cellular processes including growth, proliferation, and survival.
  • Aberrant activation of the PI3K pathway, driven by genetic and epigenetic changes, is prevalent in numerous cancer types.
  • This pathway's status influences tumor progression, prognosis, and response to therapy.

Purpose of the Study:

  • To provide a comprehensive overview of the PI3K pathway.
  • To highlight the PI3K pathway's significance in cancer biology and treatment.
  • To discuss the therapeutic potential of targeting the PI3K pathway in oncology.

Main Methods:

  • Literature review of PI3K pathway research.
  • Analysis of genetic and epigenetic alterations in PI3K pathway components.

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...
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 specific...

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 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...
