Supplementary MaterialsAdditional document 1: Shape S1. GREB1 [21] qRT-PCR: Forwards-5-GCCAAATGGAAGAAGGACAG-3; Change-5-ACCACCTACCTCCAGTCACC-3 were utilized. Primer for TFF1 [39, 40]: Forwards-5-GGCAGGCTCTGTTTGCTTAAAGAGCG-3; Change-5-GGCCATCTCTCACTATGAATCACTTCTGC-3. Statistical analysis Two-tailed Students tests were performed to determine the difference between averaged mean value. A value of ?0.05 was considered statistically significant.
