    Insights

    Leukemia inhibitory factor receptor (LIFR) signaling acts upstream of the Hippo-YAP pathway, impacting breast cancer metastasis. LIFR functions as a breast tumor suppressor, offering new research and treatment avenues.

    Area of Science:

    • Oncology
    • Molecular Biology
    • Cell Signaling

    Background:

    • Yeast and TAZ are key downstream effectors of the Hippo tumor suppressor pathway.
    • MST/LATS kinases regulate YAP/TAZ, but upstream factors remain unclear.
    • The Hippo pathway is crucial in regulating organ size and suppressing tumors.

    Purpose of the Study:

    • To elucidate the upstream regulators of the Hippo-YAP pathway.
    • To define the role of leukemia inhibitory factor receptor (LIFR) signaling in breast cancer metastasis.
    • To investigate LIFR as a potential breast tumor suppressor.

    Main Methods:

    • In vivo RNA interference screening.
    • Analysis of signaling pathways in breast cancer models.
    • Literature review and discussion of recent findings.

    Main Results:

    • LIFR signaling identified upstream of the Hippo-YAP pathway.
    • LIFR demonstrated a role in suppressing breast cancer metastasis.
    • Whole genome screening identified LIFR as a breast tumor suppressor.

    Conclusions:

    • LIFR is a novel regulator upstream of the Hippo-YAP pathway.
    • LIFR has significant implications for understanding and treating breast cancer metastasis.
    • Targeting LIFR may offer new therapeutic strategies for breast cancer.

    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...

    Regulation of Angiogenesis and Blood Supply

    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 hydroxylase and factor...

    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...

    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 rapamycin-insensitive companion...
    The JAK-STAT Signaling Pathway01:20

    The JAK-STAT Signaling Pathway

    Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as  SH2...
