Insights

AMP-activated protein kinase (AMPK) is a key regulator of cellular energy. This review explores its complex, paradoxical roles in diseases like cancer and diabetes, highlighting therapeutic challenges.

Area of Science:

  • Biochemistry
  • Cellular Metabolism
  • Molecular Biology

Background:

  • AMP-activated protein kinase (AMPK) acts as a central sensor of cellular energy status.
  • It integrates signals controlling anabolic and catabolic metabolic pathways.
  • AMPK is recognized as a significant therapeutic target for numerous human diseases.

Purpose of the Study:

  • To review and update the paradoxical roles of AMPK in various human diseases.
  • To identify challenges in targeting AMPK therapeutically.
  • To provide insights for developing rational intervention strategies.

Main Methods:

  • Literature review and synthesis of existing research on AMPK.
  • Analysis of genetic methods and AMPK agonists.
  • Discussion of AMPK's involvement in disease pathogenesis.

Main Results:

  • AMPK plays a complex and often contradictory role in diseases including cancer, type 2 diabetes, atherosclerosis, myocardial ischemia/reperfusion injury, and neurodegenerative disorders.
  • Significant progress has been made in identifying AMPK as a therapeutic target.
  • Challenges remain in fully understanding and exploiting AMPK's functions for treatment.

Conclusions:

  • AMPK's multifaceted role in energy balance presents both opportunities and challenges for therapeutic intervention.
  • Further research is needed to elucidate the precise mechanisms underlying AMPK's paradoxical effects in disease.
  • Understanding these complexities is crucial for designing effective AMPK-targeted therapies.

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...

cAMP-dependent Protein Kinase Pathways

Cyclic Adenosine Monophosphate (cAMP) is an essential second messenger that activates protein kinase A (PKA) and regulates various biological processes. A single epinephrine molecule binds to GPCR and activates several heterotrimeric G proteins, each stimulating multiple adenylyl cyclase, amplifying the signal, and synthesizing large numbers of cAMP molecules. Small changes in cAMP concentration affect PKA activity. The binding of four cAMP molecules induces a conformational change in PKA,...

MAPK Signaling Cascades01:07

MAPK Signaling Cascades

Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...

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...

Protein Kinases and Phosphatases02:54

Protein Kinases and Phosphatases

Proteins undergo chemical modifications that trigger changes in the charge, structure, and conformation of the proteins. Phosphorylation, acetylation, glycosylation, nitrosylation, ubiquitination, lipidation, methylation, and proteolysis are various protein modifications that regulate protein activity. Such modifications are usually enzyme-driven.
Protein kinases
Many proteins in the cell are regulated by phosphorylation, the addition of a phosphate group. A family of enzymes called kinases...
