    Insights

    Aberrant activation of Wnt, Notch, and Hedgehog pathways drives cancer initiation and stem cell maintenance. Targeting these embryonic pathways presents therapeutic opportunities but faces challenges due to complex signaling cross-talk.

    Area of Science:

    • Oncology
    • Developmental Biology
    • Molecular Biology

    Context:

    • Aberrant activation of Wnt, Notch, and Hedgehog signaling pathways is implicated in numerous cancers.
    • These pathways are crucial for tumor initiation, cancer stem cell (CSC) maintenance, and angiogenesis.
    • Targeting agents for these pathways have advanced to clinical trials, with Vismodegib approved for advanced basal cell carcinoma.

    Purpose:

    • To explore the role of embryonic signaling pathways in CSC function.
    • To investigate the development of novel anti-CSC therapeutic agents.
    • To understand the complexity of signaling cross-talk between these pathways in cancer.

    Summary:

    • Mutations or overexpression of Wnt, Notch, and Hedgehog pathways contribute to cancer development and progression.
    • The study examines the therapeutic potential of targeting these pathways, acknowledging the complication of signaling cross-talk.
    • Early phase I clinical studies are underway to explore these therapeutic strategies and their associated complexities.

    Impact:

    • Advances understanding of cancer stem cell biology and therapeutic vulnerabilities.
    • Highlights the potential for novel anti-cancer therapies targeting key developmental pathways.
    • Addresses the critical challenge of pathway cross-talk in the development of effective cancer treatments.

    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...

    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...

    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...

    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...

    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...

    NF-κB-dependent Signaling Pathway

    The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.
