In1-ghrelin variant in human breast samples.
Figures are generally photos, graphs and static images that would be represented in traditional pdf publications.
(A) Quantitative expression levels of the ghrelin-axis in normal (n = 4) and breast cancer samples (n = 40). (B) Correlations between In1-ghrelin and ghrelin, GOAT, GHSR1a/1b expression in breast cancer samples. (C) Quantitative expression levels of Ki67 and cyclin-D3 in normal and breast cancer samples. (D) Correlation values between In1-ghrelin and GOAT with Ki67 or cyclin-D3 expression in breast cancer samples. Values are shown as the mean ± S.E.M (** P<0.01; indicate differences from controls).
