Figure 6: Collagen Type Vi, alpha-3 (COL6A3) mRNA and protein were up regulated in mice cervix during late pregnancy, as revealed by proteomics (A) and confirmed by real time PCR (B). Levels of mRNA in early pregnancy were also found to be higher than non-pregnancy (B). However, no difference was observed in protein expression (A). (n=3 and 5 for proteomic and real time PCR analyses, respectively; p<0.05 for Figure 5A: NP/day 11 vs. day 17; Figure 5B: NP vs. day 11/17 and day 11 vs. day 17).
