A differential expression pattern of miRNAs was observed between CD24‐low clone (C14.2) and CD24‐high clone (C4) derived from an ovarian cancer patient (Figure 2A‐a), as well as between the CD24‐low and ‐high populations sorted from Caov‐3 cells (Figure 2A‐b). The gene discussed is CD24; the disease is ovarian cancer.
