Insights

The phosphatidylinositol 3-kinase (PI3K)/AKT pathway influences cancer development by altering epigenetic mechanisms like DNA methylation and histone modifications. This review explores how PI3K/AKT signaling impacts cancer epigenetics.

Area of Science:

  • Oncology
  • Molecular Biology
  • Epigenetics

Background:

  • Epigenetic alterations are crucial in cancer initiation and progression, alongside genetic changes.
  • Key epigenetic mechanisms include DNA methylation, histone modifications, and RNA-mediated regulation.
  • These processes are controlled by chromatin-associated proteins and influenced by signaling pathways.

Purpose of the Study:

  • To review how the phosphatidylinositol 3-kinase (PI3K)/AKT signaling pathway modulates epigenetic reprogramming in cancer.
  • To establish the link between the PI3K/AKT cascade and the cancer epigenome.

Main Methods:

  • Literature review of studies on PI3K/AKT signaling and epigenetic modifiers in cancer.
  • Analysis of mechanisms by which PI3K/AKT influences DNA methylation, histone modifications, and RNA regulation.
  • Examination of the role of these interactions in cancer initiation and progression.

Main Results:

  • The PI3K/AKT pathway is frequently activated in human cancers and regulates multiple biological processes.
  • Evidence shows PI3K/AKT signaling directly or indirectly modulates critical epigenetic modifiers.
  • These modulations contribute to the oncogenic functions of the PI3K/AKT pathway in various cancers.

Conclusions:

  • The PI3K/AKT pathway plays a significant role in cancer development through epigenetic reprogramming.
  • Understanding the interplay between PI3K/AKT signaling and the epigenome is vital for cancer research.
  • Targeting this crosstalk may offer novel therapeutic strategies for cancer treatment.

Epigenetic Regulation

Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

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...

Emerging Adulthood

Jeffrey Arnett's concept of emerging adulthood offers a framework to understand the unique developmental stage between adolescence and full-fledged adulthood, generally from ages 18 to 25. This period is marked by extensive exploration and shifts in identity, relationships, and career choices, a process known in psychology as role experimentation. Emerging adulthood reflects the evolving cultural expectations surrounding adulthood and the dynamic process of personal transformation during...

Regulated Protein Degradation

It is vital to regulate the activity of enzymatic as well as non-enzymatic proteins inside the cell. This can be achieved either through creating a balance between their rate of synthesis and degradation or regulating the intrinsic activity of the protein. Both these regulation mechanisms play an essential role in the normal functioning of cells.
Protein degradation plays two important roles in the cells. It helps to protect cells from misfolded or damaged proteins before they lead to a...

Covalently Linked Protein Regulators

Proteins can undergo many types of post-translational modifications, often in response to changes in their environment. These modifications play an important role in the function and stability of these proteins. Covalently linked molecules include functional groups, such as methyl, acetyl, and phosphate groups, and also small proteins, such as ubiquitin. There are around 200 different types of covalent regulators that have been identified.
These groups modify specific amino acids in a protein....
