What is the Origin of Low-Dose Effects?

This concept is central to modern toxicology and pharmacology, challenging the traditional monotonic assumption that "the dose makes the poison." It gained significant attention with the study of endocrine disruptors, where compounds at minute concentrations can mimic the body's own potent hormones. The observed non-linear effects highlight the exquisite sensitivity of cellular signaling pathways to trace amounts of active substances.

What is the Mechanism of Low-Dose Effects?

The mechanism is frequently mediated by high-affinity hormone receptors, which are designed to be activated by the low, nanomolar concentrations of endogenous hormones. At low external doses, the substance can effectively bind to and modulate these receptors, triggering subtle but profound changes in gene expression or signal transduction. This targeted modulation operates by mimicking or antagonizing physiological hormonal action, a process distinct from the generalized toxicity observed at high concentrations.

Low-Dose Effects

Meaning

Low-Dose Effects refer to the specific biological or physiological responses that are elicited by an exogenous substance, such as a drug or an environmental chemical, when administered at concentrations significantly below the level that causes a maximal or toxicological effect. These effects often manifest as non-monotonic dose-response curves, where the response at a low dose is qualitatively or quantitatively different from the response at a high dose. Understanding these low-dose actions is paramount in evaluating the safety of endocrine-disrupting chemicals.
