The Relationship between Gene Polymorphism of miRNAs Regulating FGA and Schizophrenia

SUMMARY

AIM: To investigate the relationship between the polymorphism of related gene loci of miRNAs regulated fibrinopeptide A and schizophrenia. Lay the foundation for the aetiology of schizophrenia.METHODS: Adapt to the phase match of sex and age case-control study, a total of 513 Chinese Han patients with schizophrenia were selected as the case group, 513 normal healthy persons as a control group. Obtaining SNPs information of the FGA gene by querying the dbSNP database, and reference HapMap database included SNPs site frequency information for screening. The frequency distributions of SNPs were genotyped by iMLDR® SNP detection technology. Two SNPs (pre-hsa-miR-605rs2043556 T>C, pre-hsa-miR-499a/pre-hsa-miR-499brs4909237 T < C) were analyzed to demonstrate their association with susceptibility to schizophrenia.RESULTS: There were no significant differences between patients and controls in genotype and allele distribution of SNPs(rs2043556 and rs4909237)in the precursor region of hsa-miR-605 and pre-hsa-miR-499a/pre-hsa-miR-499b. Their gene-gene interaction, which suggests that the polymorphisms of miRNA genes might not contribute to schizophrenia susceptibility in the Han Chinese population.CONCLUSION: No significant difference existed between schizophrenic patients and controls in SNP (rs2043556 and rs4909237) in the precursor region of hsa-miR-605 and pre-hsa-miR-499a/pre-hsa-miR-499b. There may not regulate FGA gene expression. Thus, hsa-miR-605 and pre-hsa-miR-499a/pre-hsa-miR-499b may not influence the risks of schizophrenia.

Factor reumatoideo, anticuerpos antipéptidos citrulinados y actividad de la enfermedad en pacientes con artritis reumatoidea Factor reumatoideo, anticuerpos antipéptidos citrulinados y actividad de la enfermedad en pacientes con artritis reumatoideaIntroducción: la artritis reumatoidea es una enfermedad inflamatoria crónica y multisistémica de causa autoinmune.Los anticuerpos antipéptidos citrulinados constituyen una herramienta importante para el diagnóstico de esta enfermedad. Objetivo: determinar la relación de los anticuerpos factor reumatoideo y antipéptidos citrulinados de segunda y tercera  generación, con indicadores clínicos y serológicos de actividad de la enfermedad en pacientes con artritis reumatoidea establecida. Material y métodos: participaron 88 pacientes con artritis reumatoidea establecida y se determinaron la proteína C reactiva, la velocidad de sedimentación globular, el índice de actividad de la enfermedad basado en el conteo de 28 articulaciones (DAS 28). Los autoanticuerpos factor reumatoideo y antipéptidos citrulinados de segunda y tercera generación se cuantificaron mediante el ensayo de inmunoabsorción ligado a enzimas. Resultados: se observó asociación entre la positividad de proteína C reactiva y la presencia de todos los autoanticuerpos. El factor reumatoideo y los anticuerpos antipéptidos citrulinados mostraron correlación positiva con la velocidad de sedimentación globular y con el DAS 28. Solamente los anticuerpos antipéptidos citrulinados se asociaron con una actividad moderada o alta de la enfermedad. Conclusiones: los anticuerpos antipéptidos citrulinados de segunda y tercera generación tienen gran valor para la identificación de pacientes con un curso más severo de la enfermedad en la artritis reumatoidea establecida.Palabras clave: artritis reumatoidea, autoanticuerpos, factor reumatoideo, antipéptidos citrulinados, enfermedad autoinmune, indicadores clínicos, indicadores serológicos.ABSTRACTIntroduction: rheumatoid arthritis is a chronic inflammatory disease, multisystem and with autoimmune cause. Antibodies anti- citrullinated peptides are an important tool for the diagnosis of this disease. Objective: to determine the relationship of rheumatoid factor, anti-mutated citrullinated vimentin and anti-citrullinated peptides of second and third generation antibodies, with clinical and serological indicators of disease activity in patients with established rheumatoid arthritis. Material and methods: 88 patients with established rheumatoid arthritis participated in the study and C reactive protein, erythrocyte sedimentation rate, disease activity score based on the count of 28 joints (DAS 28) and autoantibodies were measured.  Rheumatoid factor and anti-citrullinated peptides of second and third generation autoantibodies were quantified by enzyme-linked immunosorbent assay. Results: association between C reactive protein and the presence of all autoantibodies was observed. Rheumatoid factor and anti-citrullinated peptides antibodies of second and third generation showed positive correlation with ESR and DAS 28. Only anti-citrullinated peptide antibodies were associated with a moderate or high disease activity. Conclusions: anti-citrullinated peptide antibodies of second and third generation are of great value for identifying patients with more severe disease course in established rheumatoid arthritis.Keys words: rheumatoid arthritis, autoantibodies, rheumatoid factor, anti- citrullinated peptides, autoimmune disease, clinical indicators, serological indicators.
