    Insights

    Epigenetic silencing of WNT pathway regulators promotes cancer. Identifying and reversing these epigenetic changes offers potential new cancer therapies targeting WNT/ß-catenin signaling.

    Area of Science:

    • Molecular Oncology
    • Epigenetics
    • Cancer Biology

    Background:

    • Aberrant WNT/ß-catenin signaling is a hallmark of many human cancers.
    • Epigenetic mechanisms, including DNA methylation and histone modification, can inactivate tumor suppressors.
    • This pathway's dysregulation is crucial for tumorigenesis.

    Purpose of the Study:

    • To review the role of epigenetic dysregulation in WNT/ß-catenin signaling in cancer.
    • To highlight negative WNT regulators as potential tumor suppressors.
    • To explore therapeutic strategies targeting epigenetic silencing.

    Main Methods:

    • Literature review of epigenetic mechanisms affecting WNT signaling.
    • Analysis of studies linking epigenetic modifications to WNT pathway activation.
    • Identification of key negative WNT regulators implicated in cancer.

    Main Results:

    • Epigenetic inactivation of WNT negative regulators contributes to cancer development.
    • DNA methylation and histone modifications are key mechanisms of silencing.
    • These silenced regulators act as tumor suppressors.

    Conclusions:

    • Epigenetic dysregulation of the WNT/ß-catenin pathway is a significant driver of human malignancies.
    • Epigenetic identification of silenced WNT regulators is crucial for understanding tumorigenesis.
    • Reversing epigenetic silencing presents a promising therapeutic avenue for cancer treatment.

    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...

    Catenins01:23

    Catenins

    Catenins are characterized by multiple binding domains and dynamic structures that allow them to function as linker proteins in cell junction complexes. All catenins, except α-catenin, contain a characteristic protein sequence called the armadillo repeat and are therefore also called armadillo proteins.
    Catenins in Cell Junctions
    Catenins bind to cell adhesion molecules such as cadherins and link them to different cytoskeletal proteins depending on the type of cell junction. At the...

    Cadherins in Tissue Organization

    The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of cadherin types. Cadherins generally exhibit homophilic binding; i.e., cadherins on one cell bind to cadherins of the same or closely related type on another cell. Thus, cells of the same type have a specific affinity to bind to each other and sort themselves into clusters to form tissues.

    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...

    Cancer-Critical Genes II: Tumor Suppressor Genes

    Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
    When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
    Such genes that act...
