Figure 4: Calcium-Activated Chloride Channel Regulator (CLCAI) levels increase over pregnancy (early vs. late) in mice cervix, as revealed by proteomics (A), and verified by Western blot (B) and real time PCR (C). However, CLCAI mRNA levels in non-pregnant state were higher than early pregnancy and no difference was noted in Western blot analysis. (n=3; and 5 for proteomic and Western blot/real time PCR analyses, respectively; p<0.05 for Figure 3B, C: NP/day 11 vs. day 17and 3A: NP vs. day 11/17 and day 11 vs. day 17).
