Figure 2 Sensory nerves but not motor nerves were decreased in CIH exposed soft palate. (A) qPCR analysis quantified the mRNA levels of agrin and annexin V in the soft palate of the control group and the CIH group. (B) Western blot showing expression of annexin V in the control group and the CIH group. (C) The bar was quantitation of protein levels. The relative protein expression was calculated based on control group which was considered equal to 1. (D) Immunohistochemistry staining of annexin V on the soft palate of the control group and the CIH group. The right panel is the magnification of the white box. All values are expressed as mean±standard deviation. ** Significantly different from the control group, P<0.01. Scale bar is 100 μm.
