miRNA expression profile in human breast cancer cell line MCF-7. A total of 871 human miRNAs present in Sanger miRBase Release 13.0 was analyzed by microRNA microarray. A: The expression profile of 871 miRNAs in MCF-7. The image was displayed in pseudo colors so as to expand visual dynamic range, in which, as signal intensity increases from 1 to 57600 the corresponding color changes from blue to green, to yellow, and to red. B: miRNA distribution based on their signal intensity in microarray analysis. The stronger the signal, the higher expression a specific miRNAs. The expression level is significantly different among the 871 analyzed microRNAs.
