Insights

Ginkgetin (GK) shows promise in treating non-small cell lung cancer (NSCLC). This study reveals GK inhibits cancer cell growth and metastasis, potentially via the HSP90-AKT pathway.

Area of Science:

  • Pharmacology
  • Oncology
  • Computational Biology

Background:

  • Lung cancer (LC) is a leading cause of cancer mortality worldwide.
  • Ginkgetin (GK), a flavonoid from Ginkgo biloba, possesses known anti-tumor activities.
  • Non-small cell lung cancer (NSCLC) remains a significant therapeutic challenge.

Purpose of the Study:

  • To investigate the molecular targets and mechanisms of Ginkgetin (GK) in non-small cell lung cancer (NSCLC) therapy.
  • To integrate network pharmacology with in vitro cellular experiments.
  • To provide a scientific basis for GK as a potential NSCLC therapeutic agent.

Main Methods:

  • Network pharmacology analysis to identify potential targets and pathways.
  • Molecular docking and molecular dynamics (MD) simulations for binding affinity assessment.
  • In vitro cellular experiments to evaluate GK's effect on NSCLC cell lines (A549 and LLC).

Main Results:

  • Network pharmacology identified 52 potential targets, 5 key proteins, and 113 signaling pathways for GK against NSCLC.
  • Molecular simulations confirmed tight binding between GK and key proteins, notably EGFR.
  • Cellular experiments demonstrated that GK significantly suppresses proliferation and metastasis in A549 and LLC cells.
  • Elevated HSP90AA1 levels were observed in NSCLC, suggesting its role in the disease.

Conclusions:

  • Ginkgetin (GK) exhibits significant anti-NSCLC effects by inhibiting cell proliferation and metastasis.
  • The anti-cancer mechanism of GK likely involves the HSP90-AKT signaling pathway.
  • These findings support further research into GK as a novel therapeutic strategy for NSCLC.

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...

Notch Signaling Pathway03:14

Notch Signaling Pathway

The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not...

Hedgehog Signaling Pathway02:33

Hedgehog Signaling Pathway

The Hedgehog gene (Hh) was first discovered due to its control of the growth of disorganized, hair-like bristles phenotype in Drosophila, much like hedgehog spines. Hh plays a crucial role in the development of organs and the maintenance of homeostasis in both invertebrates and vertebrates. However, while Drosophila has only one Hh protein, mammals have multiple functional Hedgehog proteins - Sonic (Shh), Desert (Dhh), and Indian Hedgehog (Ihh). All of these homologous proteins have adapted to...

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...

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...
