Insights

AMP-activated protein kinase (AMPK) acts as a cellular energy sensor. Activating AMPK helps regulate metabolism for treating obesity, type 2 diabetes, and cancer.

Area of Science:

  • Biochemistry
  • Cellular Metabolism
  • Molecular Biology

Background:

  • AMP-activated protein kinase (AMPK) is a key cellular energy sensor.
  • It responds to metabolic stress by modulating ATP production and consumption.
  • AMPK plays a critical role in maintaining cellular energy homeostasis.

Purpose of the Study:

  • To explore the role of AMPK in regulating metabolic processes.
  • To investigate the potential of AMPK as a therapeutic target for metabolic disorders and cancer.

Main Methods:

  • The study focuses on the regulatory functions of AMPK in response to changes in the cellular AMP:ATP ratio.
  • It examines the impact of AMPK activation on ATP-consuming and ATP-generating pathways.
  • The research reviews the implications of AMPK in cellular growth and proliferation.

Main Results:

  • AMPK activation inhibits ATP-consuming processes like gluconeogenesis and fatty acid synthesis.
  • AMPK activation stimulates ATP-generating processes, such as fatty acid oxidation.
  • AMPK functions as an energy checkpoint, regulating cell growth and proliferation based on energy reserves.

Conclusions:

  • AMPK activation can ameliorate the pathogenesis of obesity and type 2 diabetes by altering lipid and glucose metabolism.
  • AMPK is a promising therapeutic target for cancer prevention and treatment due to its role as an energy checkpoint.
  • Targeting AMPK offers a potential strategy for treating both metabolic disorders and 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 rapamycin-insensitive companion...

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.

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...
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...
