The mechanisms that govern their expression are not known. miRNAs, the post-transcriptional regulators of gene expression, might be implicated. We have identified previously the miRNAs let7b, miR16, miR181a, miR200b-3p, miR200b-5p, miR223 and miR483-5p that are predicted to target Ro\/SSA [Ro52\/tripartite motif-containing protein 21 (TRIM21), Ro60\/TROVE domain family, member 2 (TROVE2)] and La\/SSB mRNAs. To study possible associations with autoantigen mRNA expression and disease features, their expression was investigated in minor salivary gland (MSG) tissues, peripheral blood mononuclear cells (PBMC) and long-term cultured non-neoplastic salivary gland epithelial cells (SGEC) from 29 SS patients (20 of 29 positive for autoantibodies to Ro\/SSA and La\/SSB) and 24 sicca-complaining controls. The levels of miR16 were up-regulated in MSGs, miR200b-3p in SGECs and miR223 and miR483-5p in PBMCs of SS patients compared to sicca-complaining controls. The MSG levels of let7b, miR16, miR181a, miR223 and miR483-5p were correlated positively with Ro52\/TRIM21-mRNA. miR181a and miR200b-3p were correlated negatively with Ro52\/TRIM21 and Ro60\/TROVE2 mRNAs in SGECs, respectively, whereas let7b, miR200b-5p and miR223 associated with La\/SSB-mRNA. In PBMCs, let7b, miR16, miR181a and miR483-5p were correlated with Ro52\/TRIM21, whereas let7b, miR16 and miR181a were also associated with La\/SSB-mRNA expression. Significantly lower miR200b-5p levels were expressed in SS patients with mucosa-associated lymphoid tissue (MALT) lymphoma compared to those without. Our findings indicate that miR16, miR200b-3p, miR223 and miR483-5p are deregulated in SS, but the exact role of this deregulation in disease pathogenesis and autoantigen expression needs to be elucidated.<\/jats:p>","DOI":"10.1111\/cei.12664","type":"journal-article","created":{"date-parts":[[2015,6,10]],"date-time":"2015-06-10T13:20:54Z","timestamp":1433942454000},"page":"14-22","source":"Crossref","is-referenced-by-count":63,"title":["Study
