Insights

Aurora kinase A (AURKA) is crucial in cancer, but targeted drugs face challenges. Targeting AURKA

Area of Science:

  • Molecular Biology
  • Cancer Biology
  • Biochemistry

Background:

  • Aurora kinase A (AURKA) is a key mitotic kinase implicated in various cellular processes beyond mitosis, including DNA replication and cell cycle progression.
  • Overexpression of AURKA is frequently observed in many cancers, correlating with poor patient prognosis and survival.
  • Current AURKA-targeted therapies are limited by toxicity and efficacy issues, with no approved drugs available.

Purpose of the Study:

  • To review recent advances in understanding AURKA regulation and its direct cancer-specific targets.
  • To identify novel therapeutic strategies by exploring the feedback loops between AURKA and its substrates.
  • To investigate the potential of targeting AURKA substrates and combination therapies for cancer treatment.

Main Methods:

  • Review of recent scientific literature on AURKA regulation and function.
  • Analysis of 33 direct cancer-specific AURKA targets and their associated oncogenic signaling pathways.
  • Examination of feedback mechanisms between AURKA and its substrates in cancer cells.

Main Results:

  • AURKA plays critical roles in ciliogenesis, mitochondrial dynamics, and neuronal outgrowth, in addition to its mitotic functions.
  • AURKA overexpression promotes aggressive oncogenic phenotypes through phosphorylation of numerous pathological substrates.
  • A common theme identified is the involvement of AURKA in feedback loops with its substrates, contributing to its sustained hyperactivation in cancer.

Conclusions:

  • The dynamic interplay between AURKA and its substrates presents a potential therapeutic vulnerability.
  • Targeting these substrates could disrupt feedback loops, leading to reduced AURKA levels and safer therapeutics.
  • Combination therapies involving AURKA inhibition and targeting its substrates may offer effective treatment strategies for AURKA-driven cancers.

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...

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

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...

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...

M-Cdk Drives Transition Into Mitosis02:15

M-Cdk Drives Transition Into Mitosis

Checkpoints throughout the cell cycle serve as safeguards and gatekeepers, allowing the cell cycle to progress in favorable conditions and slow or halt it in problematic ones. This regulation is known as the cell cycle control system.
Cyclin-dependent kinases, or Cdks, work in concert with cyclins to control cell cycle transitions. M-Cdk, a complex of Cdk1 bound to M cyclin, is a well-known example of this coordinated control that drives the transition from the G2 to the M phase.
M cyclin...
