Insights

The phosphatidylinositol-3 kinase (PI3K)-AKT pathway is frequently altered in cancer, disrupting cell division and growth. Targeting AKT, a key player in this pathway, shows promise for novel cancer therapies.

Area of Science:

  • Oncology
  • Molecular Biology
  • Biochemistry

Background:

  • The phosphatidylinositol-3 kinase (PI3K)-AKT pathway is a critical regulator of cell survival, growth, and metabolism.
  • This pathway is frequently dysregulated in various human cancers through genetic mutations, copy number alterations, and epigenetic changes.
  • Dysregulation of the PI3K-AKT pathway disrupts the balance between cell proliferation and programmed cell death, contributing to tumorigenesis.

Purpose of the Study:

  • To review the key features of the PI3K-AKT pathway.
  • To summarize the evidence linking PI3K-AKT pathway dysregulation to cancer development.
  • To discuss recent advancements in developing therapeutic agents targeting AKT for cancer treatment.

Main Methods:

  • Literature review of the PI3K-AKT pathway.
  • Analysis of evidence for the pathway's role in tumorigenesis.
  • Survey of current therapeutic strategies targeting AKT.

Main Results:

  • The PI3K-AKT pathway is a central regulator of cell homeostasis.
  • Aberrant PI3K-AKT signaling is a hallmark of many cancers.
  • AKT's downstream effectors are crucial for cancer cell survival and proliferation.
  • Targeting AKT presents a promising therapeutic avenue.

Conclusions:

  • The PI3K-AKT pathway is a significant driver of cancer.
  • AKT is an attractive, albeit challenging, therapeutic target.
  • Ongoing research focuses on developing effective AKT-targeting agents for cancer therapy.

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...

Cancer

Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.

Adaptive Mechanisms in Cancer Cells

Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

Cancer Therapies

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
