miR-155* and miR-155 are induced by TLR7 in PDCs via the JNK-signaling pathway. PDCs were cultured for 8 hours with medium or R837 in the presence or absence of LY294002, PDTC, SP600125, or SB203580. miR-155* (A) and miR-155 (B) were analyzed by TaqMan MicroRNA Expression Assay and normalized to RNU48 levels. The data are representative of at least 3 independent experiments, each based on a different PDC preparation. The data were analyzed with 2-tailed Student t test. *P < .05.
