Fig. 4

The secondary structure of microRNAs is visualized using a Force Directed Graph Layout. This figure presents the secondary structure of specific miRNAs (miR-21, miR-34a, miR-155, miR-200, miR-92, miR-221, miR-143, miR-126, miR-222, miR-10a, miR-31, miR-29a, miR-210, and miR145) as visualized through interactive graph layout software. The diagram displays the folding pattern of the miRNA molecule, highlighting key structural features such as hairpins, loops, and stems. These structural elements are crucial for miRNA function and its interaction with target mRNAs (http://mirwalk.umm.uni-heidelberg.de/human/mirna/MIMAT0000437/)
