IFI6 and nasopharyngeal carcinoma: As seen in Fig 2, there was a statistically significant increase in the fold induction of IFI6 in the KD samples compared with both the untreated control NPC line used for the shRNA experiment, and the scrambled control KD (~2-fold more robust induction with INFA2; p = 0.01 and 0.03, respectively, two-tailed Student’s t-test).
