ARHGAP5 and nasopharyngeal carcinoma: However, the correlation between miR-744 and ARHGAP5 mRNA expression didn't reach statistical significance in NPC cell lines (r = 0.7714, P = 0.0724, Figure 6e), possibly owing to the small sample size, although high miR-744 expression appeared to be associated with high level of ARHGAP5 mRNA.
