Figure 1. Time course of miRNA expression (miR-200 family) during long-term culturing of authentic UROtsa-4 cells.

Normalized levels of miR-141 (yellow), miR-200a (red), miR-200b (green), miR-200c (blue), and miR-429 (orange) are shown as determined by Real-Time PCR. RNU44 and RNU48 were used for normalization.
