Kang M, et al. - Experts explored down- and upregulated miRNAs and mRNA which could be used as potential biomarkers and/or therapeutic targets for lung cancer. In finding the novel target in cancer research, the data mining based on online databases was an effective method. They noticed important role paled by miR-33a and cullin-associated NEDD8-dissociated protein 1 (CAND1) in lung cancer proliferation and cell migration.
