Figure 1: The modulation of hsa-let-7-family miRNA in various cell lines. The analysis time indicates the period of time that had elapsed after exposure to ionizing radiation. The green color indicates upregulation and red color shows downregulation of a miRNA. The yellow color signifies no change, and the gray color indicates that the miRNAs during those time points were not examined. The orange color signified some conflicting data where it was either reported a no change or downregulation in two or more studies. Similarly the light green color indicates data where it was either reported a no change or upregulation in two or more studies.
