Abstract
Purpose of the review
This review will provide an updated perspective of the relationship between obstructive sleep apnea (OSA) based on the latest experimental research carried out on animal models subjected to chronic intermittent hypoxia (IH) as a subrogate of OSA.
Recent findings
During the last years, new research linking IH and cancer has emerged. The most recent studies have (1) increased the number of types of tumor investigated in response to IH and (2) explored some of the potential mechanisms modulated by IH which could participate in the increased cancer incidence and malignancy reported under this challenge.
Summary
There are increasing evidences showing that IH mimicking OSA increases tumor incidence, malignancy, and mortality in mice. The mechanisms explored to date are related to the induction of hypoxia-inducible factors, inflammatory and oxidative stress markers, angiogenesis, and IH-induced alterations on the immune system (macrophages and lymphocytes).
