Figure 4. Western blot analysis of decreasing expression of LF and increasing expression of VMO1 homolog in camel tears in the summer compared to the winter. A, B: Comparison of expression of LF (A) and VMO1 homolog (B) between the summer group (Cs) and the winter group (Cw) by western blotting. C, D: Relative quantitative analysis of each corresponding band of LF (C) and VMO1 homolog (D) in two groups, based on the volume intensity of the band in Cw as 1.0. The paired student’s t test was performed and showed a significant difference (*p=0.042, **p=0.002) between two groups.
