Figure 1. Summary of Hydbring et al.
Through several screens, it was determined that a subset of miRNAs target cyclins and CDKs, which are positive drivers of the cell cycle. These “cell-cycle-targeting miRNAs” were found to be inversely correlated with cyclins/CDKs in The Cancer Genome Atlas (TCGA) data, as well as either reduced or deleted in several tumor types. Therapeutic efficacy of these cell-cycle-targeting miRNAs was enriched in TNBC and gastric cancer cell lines, which was validated in chemotherapy-resistant PDX models.
