Insights

Dietary virgin olive oil and its phytochemicals may target stress-activated mitogen-activated protein kinases (MAPKs) involved in cancer. Olive-derived compounds show potential as cancer prevention agents and chemotherapy adjuvants.

Area of Science:

  • Molecular Biology
  • Oncology
  • Nutritional Science

Background:

  • Mitogen-activated protein kinases (MAPKs) are crucial in inflammation and cancer, regulating proliferation, apoptosis, and immune escape.
  • Current MAPK-targeting therapies face challenges like adverse effects and paradoxical pathway activation.
  • Dietary factors can modulate cancer initiation and progression by interacting with MAPKs.

Purpose of the Study:

  • To review studies on the effects of olive-derived foodstuffs and nutraceuticals on MAPK signaling cascades.
  • To explore the potential of virgin olive oil (VOO) and its components in cancer prevention and therapy.

Main Methods:

  • Literature review of experimental studies investigating olive-derived compounds and MAPK pathways.
  • Analysis of the role of virgin olive oil's squalene content in drug delivery and phytochemical interaction.

Main Results:

  • Experimental studies suggest stress-activated JNK and p38 MAPKs are potential targets of olive-derived nutraceuticals.
  • Phytochemicals from olive cultivation and processing wastes may act as adjuvants in chemotherapy.
  • Virgin olive oil, rich in squalene, shows potential as a natural delivery system for bioactive phytochemicals.

Conclusions:

  • Olive-derived nutraceuticals, including phytochemicals, may modulate MAPK signaling, offering therapeutic potential in cancer.
  • Virgin olive oil serves as a natural delivery system for bioactive compounds, supporting cancer prevention and treatment strategies.

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...

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...

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...

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...

Inhibition of Cdk Activity02:34

Inhibition of Cdk Activity

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...

The Intrinsic Apoptotic Pathway01:31

The Intrinsic Apoptotic Pathway

Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...
