Effect of IH on the expression of inflammatory cytokines in the liver (H and E, original magnification, ×100). (a and b) H and E staining of liver tissues harvested from the control and IH groups. (c-e) The mRNA expression levels of IL-1β, IL-6, and TNF-α were determined in the control and IH groups by quantitative reverse transcription polymerase chain reaction, using Gapdh as the housekeeping gene. The data are presented as the mean ± standard error. *P < 0.05, compared with the control group. IH: Intermittent hypoxia; mRNA: messenger RNA; IL-1β: Interleukin-1beta; TNF-α: Tumor necrosis factor-alpha.
