Insights

Natural products can modify cancer cell signalling pathways, including MAPK, PI3K/AKT/mTOR, and Wnt/β-catenin. This review explores how phytochemicals target cancer by inhibiting these pathways, inducing apoptosis, and reducing tumor growth.

Area of Science:

  • Oncology
  • Molecular Biology
  • Pharmacology

Background:

  • Cancer development involves genetic/epigenetic alterations in key cell signalling pathways like MAPK, PI3K/AKT/mTOR, and Wnt/β-catenin.
  • These pathways regulate crucial cellular processes including growth, division, and apoptosis, making their dysregulation a hallmark of oncogenesis.
  • Aberrant signalling in these pathways presents therapeutic targets for cancer treatment.

Purpose of the Study:

  • To review the role of natural products in modulating cancer-related molecular signalling pathways.
  • To highlight the mechanisms by which phytochemicals from natural products exert anti-cancer effects in preclinical models.
  • To discuss the potential of phytopharmaceuticals in evidence-based oncology.

Main Methods:

  • Literature review of preclinical studies on natural products and cancer signalling pathways.
  • Analysis of data demonstrating phytochemicals' effects on molecular targets.
  • Examination of mechanisms including pathway inhibition, apoptosis induction, and tumor growth reduction.

Main Results:

  • Natural products contain bioactive phytochemicals that target cancer cells by inhibiting specific signalling pathways.
  • These compounds demonstrate efficacy in preclinical models by inducing apoptosis, inhibiting tumor growth, and altering oncogenic crosstalk.
  • Evidence shows natural products can modify MAPK, PI3K/AKT/mTOR, and Wnt/β-catenin signalling cascades.

Conclusions:

  • Natural compounds offer a promising avenue for developing targeted cancer therapies by modulating key signalling pathways.
  • A pathway-centered approach is crucial for understanding the therapeutic mechanisms of natural products.
  • Further research is needed to address study variability, bioavailability, and robustness to integrate phytopharmaceuticals into clinical oncology.

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...
Targeted Cancer Therapies02:57

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 specific...
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.

Non-Canonical Wnt Signaling Pathways

Wnt is a zygotic effect gene that is expressed during very early embryonic development. It regulates various processes in animals starting from early development through the adult stage, such as organogenesis in the embryo and maintenance of neuronal and blood stem cells. Wnt proteins can induce a wide variety of intracellular pathways depending upon the specific abilities of different Wnt ligands to form a complex with shared and cognate receptors in the presence of different co-receptors. The...

Canonical Wnt Signaling Pathway

The gene encoding the main signaling molecules of the Wnt signaling pathways (the Wnt proteins) was discovered almost four decades ago by Nüsslein-Volhard and Wieschaus. They identified and originally named the gene "wingless" (wg) after a phenotype discovered during their landmark genetic screen in Drosophila for body pattern defects. At around the same time, another researcher named Harold Varmus found that a murine tumor virus activates the mammalian wg homolog, Int-1, which results in tumor...
