Insights

AMP-activated protein kinase (AMPK) is crucial for cellular energy balance. Emerging research highlights AMPK

Area of Science:

  • Cellular Biology
  • Metabolic Regulation
  • Oncology

Background:

  • AMP-activated protein kinase (AMPK) is a key regulator of cellular energy homeostasis, activated by energy deprivation.
  • AMPK plays a role in promoting ATP production and managing metabolic energy.
  • AMPK is a known therapeutic target for metabolic syndrome and type-2 diabetes.

Purpose of the Study:

  • To review the multifaceted role of AMPK in regulating inflammation, metabolism, and other processes, with a focus on cancer.
  • To discuss the potential of targeting AMPK for cancer prevention and treatment.
  • To evaluate the evidence linking AMPK to tumor suppressor functions and analyze underlying molecular mechanisms.

Main Methods:

  • Review of recent epidemiological studies on metformin and cancer incidence.
  • Analysis of scientific literature on AMPK's role in various cancer types.
  • Evaluation of molecular mechanisms underlying AMPK's tumor suppressor activity.

Main Results:

  • AMPK activation is associated with reduced cancer incidence, as suggested by epidemiological studies on metformin.
  • AMPK activation has been observed to oppose tumor progression in several cancer types.
  • AMPK's tumor-suppressive function is partly mediated through the regulation of inflammation and metabolism.

Conclusions:

  • AMPK is emerging as a significant metabolic tumor suppressor and a potential therapeutic target for cancer.
  • Targeting AMPK offers a promising strategy for various cancer therapies.
  • AMPK activity counteracts tumor development and progression through its regulatory effects on inflammation and metabolism.

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.

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...

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...

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...
