BECN1 and obstructive sleep apnea syndrome: Beclin1 immune-positive cells were rarely seen in the SO group; compared with the SO group, the I/R group showed an increased number of beclin1 immune-positive cells at each time point (P<0.05); compared with the I/R group, each of the OSAHS hypoxia groups showed an increased number of beclin1 immune-positive cells at each time point (P<0.05); compared with the IH+I/R group, the inhibitor group also showed an increased number of beclin1 immune-positive cells at each time point (P<0.05).
