Abstract:
To explore the serum miR-338-5p expression characteristics in renal transplant recipients ,and the role of regulating BAFF signal ,then investigate its biological significance.Methods:Healthy volunteers were enrolled as control group.Serum miR-338-5p was detected by real-time PCR;soluble BAFF was detected by ELISA;anti-HLA-Ⅰantibody,anti-HLA-Ⅱ antibody and anti-MICA antibody were detected by liquid chip technology.SPSS17.0 software was applied.t-test was used to compare the means of two independent samples;Paired samples t-test was used to compare the means of two paired samples;Spearman method and Pearson method were used to analyse the correlation;P<0.05 was considered to be statistically significant.Results: Compared with healthy controls,serum miR-338-5p in renal transplant recipients decreased significantly (P<0.001),while serum BAFF increased significantly (P<0.01).Serum miR-338-5p levels within 1 year post-transplantation were significantly lower than that of more than 1 year post-transplantation (P<0.01);Serum miR-338-5p levels within 3 years post-transplantation were significantly lower than that of more than 3 years post-transplantation (P<0.01);To all research objects,serum miR-338-5p was significantly negatively correlated with serum BAFF (r=-0.51,P<0.001),and serum miR-338-5p was significantly negatively correlated with anti-HLA-Ⅱ antibody(r=-0.322, P<0.05);Serum miR-338-5p within 3 years was significantly negatively correlated with anti-HLA-Ⅱantibody (r=-0.423,P<0.05), and serum miR-338-5p within 3 years was significantly negatively correlated with anti-MICA antibody(r=-0.411,P<0.05);Serum miR-338-5p more than 3 years was significantly positively correlated with anti-MICA antibody(r=0.486,P<0.05),and Serum miR-338-5p more than 3 years was significantly positively correlated with anti-HLA & MICA antibody(r=0.578,P<0.01).Conclusion:miR-338-5p may directly or indirectly target BAFF signal ,and participate antibody mediated immune response by regulating its target genes and interfere with the long-term survival of transplanted renal.
