Differential miRNA expression in tumor cells. A) AA patients compared to EA TNBC tumor cells that were preserved using FFPE. B) TNBC tumor cells preserved using formalin fixed, paraffin embedded sections were compared to frozen sections. Data compares method of fixation and contains both AA and EA samples. Selected miRNAs are listed from top to bottom: let7g, 19a, 30a-3p, 95, 192, 206, 211, 302a, 302b, 302c, 335, 367, 367c, 372, 275, 520b, 520f, 548d, 601 and 645. The length of the bar represents increased quantity of difference in miRNA expression.
