Figure 7. Increased expression of AGR2 is associated with Tgfbr1 deletion.
(A) Immunohistochemistry of AGR2 in tongue of the wild type (WT) mice, the tumor of Pten conditional knock out mice, Tgfbr1 conditional knock out mice and Pten/Tgfbr1 conditional knock out mice (Scale bar+25μm); (B) Quantitative of histoscore of AGR2 in wild type mice, Pten conditional knock out mice, Tgfbr1 conditional knock out mice and Pten/Tgfbr1 conditional knock out mice. Expression of AGR2 in Tgfbr1 conditional knock out mice and Pten/Tgfbr1 conditional knock out mice was significantly higher than the wild type mice (P < 0.001); (C) Quantitative Real-time PCR revealed the mRNA level of AGR2 in Tgfbr1 conditional knock out mice and Pten/Tgfbr1 conditional knock out mice was significantly increased when compared with the wild type mice; (D) Western blot analysis of AGR2 48h after knocking down PTEN, TGFBR1, and combined TGFBR1/PTEN by using siRNA; (E) Quantitative analysis showed the protein level of AGR2 in TGFBR1 siRNA group and TGFBR1/PTEN combined siRNA group were significantly higher than the control group (P < 0.001). Mean±SEM, ***, P<0.001.
