    Insights

    Tumours develop resistance to targeted therapies by rewiring signaling networks. Quantitative studies reveal how feedback loops in MAPK/PI3K pathways impact drug sensitivity, offering insights for improved cancer treatments.

    Area of Science:

    • Oncology
    • Molecular Biology
    • Systems Biology

    Background:

    • Over 20 FDA-approved kinase inhibitors are used clinically for cancer treatment.
    • Tumor resistance to targeted therapies is a significant clinical challenge.
    • Mechanisms of resistance include the rewiring of cellular signaling networks.

    Purpose of the Study:

    • To review insights from quantitative signaling studies on drug resistance.
    • To explain how feedback mechanisms rewire signaling pathways.
    • To elucidate the impact of rewiring on drug sensitivity.

    Main Methods:

    • Review of recent quantitative signaling studies.
    • Integration of mathematical modeling with experimental data.
    • Analysis of feedback loops in MAPK/PI3K signaling pathways.

    Main Results:

    • Feedback mechanisms can reactivate or reroute signaling pathways in tumors.
    • Rewiring of MAPK/PI3K signaling networks occurs upon treatment.
    • Altered signaling networks affect the sensitivity of tumors to kinase inhibitors.

    Conclusions:

    • Understanding feedback-driven signaling rewiring is crucial for overcoming drug resistance.
    • Quantitative signaling studies provide valuable insights into complex cellular behaviors.
    • This knowledge can inform the development of more effective targeted cancer therapies.

    Targeted Cancer Therapies

    The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
    There are several types of targeted therapies against...

    Cell Signaling Feedback Loops

    Positive and negative feedback loops are crucial for regulating biological signaling systems. These feedback loops are processes that connect output signals to their inputs.
    Negative feedback loops
    Most signaling systems have negative feedback loops that can perform different functions such as output limiter, and adaptation.
    Output limiter
    Upon receiving an input signal, the cellular response rapidly increases until a threshold is reached. Beyond this threshold, a negative feedback loop...

    Amplifying Signals via Enzymatic Cascade

    When a ligand binds to a cell-surface receptor, the receptor's intracellular domain changes shape, which may either activate its enzyme function or allow its binding to other molecules. The initial signal is amplified by most signal transduction pathways. This means that a single ligand molecule can activate multiple molecules of a downstream target. Proteins that relay a signal are most commonly phosphorylated at one or more sites, activating or inactivating the protein. Kinases catalyze...

    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...

    Transducer Mechanism: Enzyme-Linked Receptors

    Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
    Major types that are helpful drug targets include:
