    Insights

    Steroid hormones regulate gene expression via cell receptors, influencing biological responses. Disruptions in this pathway, from hormone production to receptor function, lead to impaired cellular signaling and loss of normal biological responses.

    Area of Science:

    • Molecular Biology
    • Endocrinology
    • Genetics

    Background:

    • Steroid hormones are crucial signaling molecules.
    • Their biological effects are mediated by specific cellular mechanisms.
    • Understanding this process is key to comprehending various physiological functions.

    Purpose of the Study:

    • To elucidate the detailed molecular mechanism of steroid hormone action.
    • To highlight the role of gene expression regulation in steroid hormone signaling.
    • To identify critical steps and potential points of failure in the steroid hormone pathway.

    Main Methods:

    • The study describes the pathway of steroid hormone action.
    • It involves hormone entry into target cells, receptor binding, and nuclear translocation.
    • Gene transcription, RNA processing, and protein synthesis are detailed.

    Main Results:

    • Steroid hormones bind to cytoplasmic receptors, forming complexes.
    • These complexes translocate to the nucleus, interacting with DNA to initiate transcription.
    • This process leads to the synthesis of specific proteins that mediate biological responses.

    Conclusions:

    • Steroid hormone action is a multi-step process centered on gene expression regulation.
    • The integrity of each step, including hormone production and receptor function, is essential for normal biological responses.
    • Impairments at any stage can result in significant physiological disturbances.

    Intracellular Hormone Receptors01:08

    Intracellular Hormone Receptors

    Lipid-soluble hormones diffuse across the plasma and nuclear membrane of target cells to bind to their specific intracellular receptors. These receptors act as transcription factors that regulate gene expression and protein synthesis in the target cell
    Internal Receptors01:31

    Internal Receptors

    Many cellular signals are hydrophilic and therefore cannot pass through the plasma membrane. However, small or hydrophobic signaling molecules can cross the hydrophobic core of the plasma membrane and bind to internal, or intracellular, receptors that reside within the cell. Many mammalian steroid hormones use this mechanism of cell signaling, as does nitric oxide (NO) gas.

    Signal Transduction: Overview

    Cells respond to many types of information, often through receptor proteins positioned on the membrane. They respond to chemical signals, such as hormones, neurotransmitters, and other signaling molecules, initiating a series of molecular reactions to produce an appropriate response. This is called signal transduction. Cells also coordinate different responses elicited by the same signaling molecule via mediators, allowing molecular cross-talk.
    Typically, signal transduction involves three...

    Secondary Messengers in Hormone Action

    Water-soluble hormones cannot cross the plasma membrane, so they rely on protein receptors that span the membrane to trigger intracellular signaling pathways. These pathways then activate second messengers inside the cell, including cAMP or calcium ions.
    Many hormones bind to transmembrane G protein-coupled receptors that connect to regulatory G proteins. These G proteins can then activate enzymes such as adenylyl cyclase or phospholipase C. Adenylyl cyclase converts ATP to cAMP, activating...
    Target Cell Response to Hormones01:22

    Target Cell Response to Hormones

    Hormones intricately bind to receptors on the surface or within target cells, initiating a cascade of cellular responses.
    Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...
