Summary
Cananginone, a plant-derived compound, effectively combats cancer stem cell renewal and Epithelial-Mesenchymal Transition (EMT) by inhibiting the Hh-Gli pathway. This research reveals its potential as a novel anti-cancer therapeutic agent.
Area of Science:
- Natural Products Chemistry
- Cancer Biology
- Pharmacology
Background:
- Cananginones are linear acetogenins from plants with known anti-cancer properties.
- Cancer stem cell renewal and Epithelial-Mesenchymal Transition (EMT) are critical processes in cancer progression and drug resistance.
Purpose of the Study:
- To investigate the anti-cancer efficacy and mechanism of cananginone.
- To explore cananginone's effects on cancer stem cell renewal, EMT, and the Hh-Gli pathway.
Main Methods:
- In vitro screening of cananginone against various cancer cell lines (HepG2, PC3, A549, MCF7).
- Cell-based assays to assess cancer stem cell renewal, EMT, reactive oxygen species (ROS) levels, and cell viability.
- Investigation of cananginone's effect on the Hh-Gli pathway, specifically Gli1 inhibition.
Main Results:
- Cananginone demonstrated anti-cancer activity, with higher potency against MCF7 cells.
- Cananginone abrogated cancer stem cell renewal and inhibited EMT.
- Increased ROS levels were observed, leading to reduced cancer cell viability.
- Cananginone inhibited Gli1 in a non-canonical Hh pathway, distinct from known antagonists.
Conclusions:
- Cananginone exhibits significant anti-cancer properties by targeting cancer stem cell renewal and EMT.
- The compound's novel mechanism involves non-canonical inhibition of the Hh-Gli pathway.
- Cananginone represents a promising candidate for further development as an anti-cancer therapeutic.

02:33Hedgehog Signaling Pathway
7.6K
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...

01:12Role Of Notch Signalling In Intestinal Stem Cell Renewal
2.2K
Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...

9.1K
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...

7.5K
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...

01:24Regulation of Angiogenesis and Blood Supply
2.8K
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

03:14Notch Signaling Pathway
4.5K
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...
