ABSTRACT

Objective To investigate the relationship between FGF23 and Klotho in GD patients. Methods From March 2016 to November 2016, forty-three newly diagnosed and untreated Grave disease patients (GD group) and 27 healthy subjects were selected. Meanwhile,Peripheral venous serum was collected to detect serum calcium, phosphorus and thyroid function in GD group. The levels of FGF23, Klotho protein and 1 in each group were detected by enzyme-linked immunosorbent assay ( ELISA ) . The expression levels of FGF23,Klotho protein and 1,25-dihydroxyvitamin D3 were detected by enzyme-linked immunosorbent assay ( ELISA ) . The differences of FGF23, Klotho protein, 1, 25-dihydroxyvitamin D3, serum calcium and phosphorus between GD group and normal control group were compared,and the correlation between each index was analyzed. The relationship between FGF23 and Klotho protein and the pathogenesis of GD was explored. Results ( 1) Thyrotropin in thyroid function was significantly lower in GD group than that in normal group,and the difference was statistically significant ( 0. 003 ( 0. 002, 0. 004 ) mU/L vs. 1. 650 ( 0. 81, 2. 14 ) mU/L, Z=- 7. 587,P<0. 05] . Thyrotropin receptor antibodies,free triiodothyronine and free thyroxine in GD group were significantly higher than those in normal group. There were [ thyroid stimulating hormone receptor antibodies:9. 03(3. 89,21. 29)) U/L vs. 0. 60(0. 38,0. 97)) U/L,free triiodothyronine:23. 36(11. 61,38. 00)) pmol/L vs. 4. 63(4. 03,4. 92)) pmol/L,free thyroxine:4. 34(33. 94,100. 00) pmol/Lvs. 17. 69(15. 80,20. 35) pmol/L;Z=-6. 694,-6. 878,-6. 836,P<0. 05];( 2) The serum levels of FGF23,Klotho and phosphorus in patients with hyperthyroidism were significantly higher than those in the normal group,and the difference was statistically significant [FGF23:(524. 2±66. 7) ng/L vs. (467. 2±64. 5) ng/L,Klotho:8. 29(6. 89,11. 37) pg/ml vs. 6. 69 (6. 36,7. 53) pg/ml,phosphorus:1. 33(1. 03,1. 52) mmol/L vs. 1. 02(0. 84,1. 20) mmol/L; t=3. 517,Z=-3. 936,-3. 795,P<0. 05]. The Results of correlation analysis showed that: (1) There was no correlation among FGF23 and Klotho,thyroid stimulating hormone receptor antibody,free thyroxine,1,25-dihydroxyvitamin D3,phosphorus and calcium a ( P>0. 05);( 2) There was no correlation among Klotho and thyroid stimulating hormone receptor antibody, free thyroxin, 1, 25-dihydroxyvitamin D3, phosphorus and calcium ( P>0. 05 ) .

ABSTRACT

To identify association between the presence of previously reported four single nucleotide polymorphisms(SNPs) at exon 10, 12 and 33 of thyroglobulin(Tg) gene with autoimmune thyroid disease(AITD) patients whose TgAb is positive. In this case-control association study, the Tg gene polymorphisms at exon 10, 12, and 33 were determined by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP)method in 222 patients with AITD. According to the titers of the Tg autoantibodies(TgAb) in serum, they were divided into two subgroups: TgAb positive group and TgAb negtive group. And a haplotype case-control analysis was also done in two groups.The difference of their frequencies was analyzed by Chi-square test. No differences in alleles and genotypes frequencies were observed in all patients whose TgAb iseither positive or negative(P>0.05). But there was a significant association of G-C-A-C haplotype with the patients whose TgAb was positive(P=0.028,OR=3.34). There is association of thyroglobulin gene polymorphisms with TgAb in patients with AITD.

ABSTRACT

BACKGROUND: Previous studies found that C57BL/6 mouse was susceptible to atherosclerosis, while BALB/c mouse was resistant to atherosclerosis. The stenosis of the culprit vessel and the severity of myocardial infarction were correlated to the levels of OX40L expression. Whether OX40L has differential expression between C57BL/6 and BALB/c mouse was not identified.OBJECTIVE: To observe the differential expression of OX40L mRNA and protein in C57BL/6 and BALB/c mouse.METHODS: Total RNA and protein were extracted by Trizol and RIPA Buffer from heart, brain, kidney, skeletal muscle and spleen tissues of C57BL/6 and BALB/c mice. RT-PCR and Western Blot were used to detect OX40L mRNA and protein expression in heart, brain, kidney, spleen and skeletal muscle of two kinds of mice. The differential expression of OX40L mRNA and protein between C57BL/6 and BALB/c mice was observed.RESULTS AND CONCLUSION: RT-PCR results showed that the mRNA expression level of OX40L in heart of C57BL/6 mice mouse was significantly higher than BALB/c mice (P < 0.05); the mRNA expression level of OX40L in spleen of BALB/c mice was significantly higher than C57BL/6 mice (P < 0.05). There were no significant differences in the brain, kidney and skeletal muscle between these two strains. The results of Western Blot showed that the protein expression level of OX40L in heart, brain and kidney of C57BL/6 mice were significantly higher than BALB/c mice (P < 0.05). There were no significant differences in skeletal muscle and spleen between these two strains. The OX40L mRNA transcription level in heart was higher in C57BL/6 mouse than BALB/c mouse, while the expression in spleen was lower than the latter. The OX40L protein levels in C57BL/6 mouse heart, brainand kidney were higher than BALB/c mouse. The differences of OX40L expression between the two strains of mice indicated that OX40L may promote to C57BL/6 mouse susceptible to atherosclerosis.
