Low oxygen (O2) conditions profoundly affect animals’ behavior and physiology, and underlie the pathogenesis of various human disorders. However, the fundamental mechanisms underlying a variety of hypoxia-induced responses remains elusive.

We leverage the powerful genetics in C. elegans to address the challenges associated with studying hypoxia-evoked adaptations, focusing primarily on acute hypoxia sensing, hypoxia-evoked appetite inhibition, and anoxia tolerance.

Our approach involves thoroughly dissecting these processes in C. elegans and actively translating the findings to mammals. A doctoral student and a senior staff scientist will be engaged to implement the proposed research.

Building upon substantial preliminary data, the proposed research presents a feasible strategy to delineate the signal transduction upon acute hypoxia stimulation and elucidate the mechanism of hypoxia-induced appetite inhibition within 2-3-years.

Moreover, we aim to illuminate the roles of a voltage-gated potassium channel and IL-17 in anoxia tolerance within this funding window.

Our ultimate goal is to derive conserved principles underlying hypoxia-evoked adaptation, thereby enhancing our understanding of the etiology of hypoxia-related disorders and inspiring the development of innovative treatments.

Additionally, our findings could shed light on how parasitic nematodes survive in hypoxic or anoxic host niches, informing novel therapeutic targets against parasitic infections.
