Insights

AMP-activated protein kinase (AMPK) is crucial for cellular metabolism and energy balance, impacting diseases like diabetes and cancer. This study explores AMPK

Area of Science:

  • Biochemistry
  • Cellular Metabolism
  • Molecular Biology

Background:

  • Cellular metabolism impairments drive disease progression.
  • AMP-activated protein kinase (AMPK) regulates anabolic-catabolic processes and energy metabolism.
  • AMPK's role in fat, carbohydrate, protein metabolism, growth, and autophagy makes it a target for chronic diseases.

Purpose of the Study:

  • To provide information on the AMPK enzyme.
  • To elucidate the role of AMPK in cancer and metabolic disorders.
  • To discuss developed AMPK activators.

Main Methods:

  • Literature review of AMPK's function in metabolic pathways.
  • Analysis of AMPK's involvement in cancer development and progression.
  • Review of current AMPK activators and their therapeutic potential.

Main Results:

  • AMPK is central to energy metabolism, influencing fat, carbohydrate, and protein pathways.
  • AMPK dysregulation is implicated in Type 2 diabetes, metabolic syndrome, obesity, inflammation, and cancer.
  • AMPK may exert anticancer effects beyond cell cycle suppression, potentially by influencing glycolysis and the Warburg effect.

Conclusions:

  • AMPK is a key regulator of cellular metabolism with significant implications for various diseases.
  • Targeting AMPK offers potential therapeutic strategies for metabolic disorders and cancer.
  • Further research into AMPK activators is warranted for clinical applications.

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.

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 Pathways01:25

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,...

Adaptive Mechanisms in Cancer Cells02:53

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,...

Electron Transport Chain: Complex I and II

The mitochondrial electron transport chain (ETC) is the main energy generation system in the eukaryotic cells. However, mitochondria also produce cytotoxic reactive oxygen species (ROS) due to the large electron flow during oxidative phosphorylation. While Complex I is one of the primary sources of superoxide radicals, ROS production by Complex II is uncommon and may only be observed in cancer cells with mutated complexes.
ROS generation is regulated and maintained at moderate levels necessary...

Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
