Expression of miR-146a appears to vary in different cancer tissues in which an increased level of miR-146a was observed in Burkitts' lymphoma lines with EBV-LMP1 (latent membrane protein 1) expression [37], [38], but a decreased level in hormone-refractory prostate cancer [39] and papillary thyroid carcinoma [40]. The gene discussed is PDLIM7; the disease is differentiated thyroid carcinoma.
