The Expression of MiRNAs Was Compared in Normal Cells and Cancer

The expression of miRNAs was compared in normal cells and cancer cells using a microarray. miRNAs from cancer cells were labeled with green fluorescent tags, and miRNAs from normal cells were labeled with red fluorescent tags. miRNA #1 was overexpressed in cancer cells, miRNA #2 was not expressed in either cell type, miRNA #3 was underexpressed in cancer cells, and miRNA #4 was equally expressed in both cell types. Which of the following microarrays illustrate these findings?

A)

B)

C)

D)

E)
