GJA1 and neoplasm: The results demonstrated that the relative expression of GJA1 was 7.3553 (6.6179, 8.002) in the age ≤ 60 group and 7.0655 (6.2779, 7.7754) in the age > 60 group with p value ≤ 0.05 (Figure 4A), and the expression of GJA1 decreased with increasing tumor pathologic and histologic stage (Figure 4B,C).
