Metallothionein induction attenuates the progression of lung injury in mice exposed to long-term intermittent hypoxia

Background Intermittent hypoxia (IH), a hallmark of obstructive sleep apnea (OSA), is prevalent in older adults and associated with inflammation. We previously showed that IH induces renal fibrosis and cardiomyopathy and hypothesized that lung inflammatory changes may underlie deficits in pulmonary function in OSA.
