Figure 4: ((a), (b), and (c)) Western blot of paired normal/malignant TNBC samples (1–48). Total number of samples () analyzed per group was as follows: Heterozygous (Het; ), Homozygous with SNP (Hom SNP; ), and Homozygous (Hom; ). Bar graphs (a–c) of free proIGF-II (17.5 kDa) and Survivin (16.5 kDa). Ponceau red staining was used to normalize for sample loading. Bars represent the mean ± SE of all normalized samples per group. Asterisks indicate values statistically significant () using the Wilcoxon paired -test.
