What is the Origin of Non-Monotonic Dose Response?

The concept originated in the field of toxicology, specifically in studies investigating the effects of endocrine-disrupting chemicals (EDCs) and hormones at low, environmentally relevant concentrations. The term non-monotonic describes the deviation from the expected monotonic relationship, where the effect continuously changes in one direction with increasing dose. This discovery necessitated a re-evaluation of safety testing protocols for hormonal agents.

What is the Mechanism of Non-Monotonic Dose Response?

The mechanism is often explained by the presence of multiple receptor types with different affinities, or by the involvement of distinct signaling pathways that are activated sequentially or competitively. For example, a low dose might activate a high-affinity receptor to produce a beneficial effect, while a higher dose might saturate that receptor and simultaneously activate a lower-affinity, counter-regulatory pathway, thereby attenuating or reversing the initial response.

Non-Monotonic Dose Response

Meaning

A Non-Monotonic Dose Response (NMDR) describes a biological relationship where the magnitude of the response to a substance does not increase or decrease consistently with an increase in the dose. Instead, the response curve may be U-shaped or inverted U-shaped, meaning a substance may have a greater effect at very low doses than at higher doses. This pattern is particularly important in endocrinology and toxicology, challenging the traditional assumption that “the dose makes the poison.”
