Interestingly, the levels of expression of In1-ghrelin variant and GOAT levels showed a trend to or were positively correlated with the expression of Ki67 (p = 0.069 and p = 0.109, respectively) and cyclin-D3 (p = 0.009 and p = 0.059, respectively) in breast cancer samples (Fig. 3D). This evidence concerns the gene GHRL and breast carcinoma.
