Increase in uterine at-RA level and decrease in its synthase levels during mice peri-implantation following pCR3.1-cyp26a1 immunization, especially on D5 of mice pregnancy. (A) high performance liquid chromatography (HPLC) chromatographs of RA. 1 for 13-cis-RA; 2 for 9-cis-RA; 3 for at-RA. (B) The HPLC chromatograms of D5 uterine at-RA. (C) Uterine at-RA concentration (ng/g) increased in uterus based on uterine at-RA concentration (ng/g) trend graph, under the influence of recombinant plasmid. The uterine at-RA concentration (ng/g) was evaluated by HPLC analysis. Pairwise comparisons were taken between each treatment group, *P < 0.05. At least, five independent experiments were repeated for each time-point. A total of 74 mice were assessed. (D) RALDH1A1 and RALDH1A2 levels were significantly reduced at uterine implantation sites based on Western blotting of pregnancy D5. β-actin was used as a loading control.
