Project description:Familial Mediterranean fever (FMF) is an inflammatory genetic disease characterized by elevated systemic reactivity against commensal gut microbiota and high levels of gut Candida albicans. The current study investigated the effects of Lactobacillus acidophillus INMIA 9602 Er 317/402 strain (probiotic “Narine”) on the relative abundance of gut enteric bacteria, lactobacilli, Staphylococcus aureus, and Enteroccocus faecalis in Candida albicans-carrier and non-carrier FMF patients in remission with the main MEFV mutation patterns M694V/V726A- the prevalent MEFV gene mutation within FMF patients in the Armenian cohort. Our data revealed that M694V/V726A mutations in PURIN inflammasome leading to FMF disease brought to gender specific differences in microbial community structure in FMF patients. Possibly, long-term colchicine use suppresses the PURIN inflammasome/inhibits NLRP3 inflammasome-dependent IL-1β release influencing on overgrowth of C. albicans in gut microbiota of FMF patients. The comparison of Operational Taxonomic Units (OTUs) of enteric bacteria in C. albicans-carrier and non-carrier female patients revealed the statistically significant increase in OTUs of enterobacteria in C. albicans-carriers. In contrast to this, there were no differences in abundance of Enteroccocus faecalis between female FMF C. albicans-carriers compared with non-carriers, while male FMF C. albicans-carriers have increased abundance of E. faecalis in their gut microbiota compared with that of male patients with none carriers. The gut microbiota of FMF patients (both male and female) with C. albicans below baseline level contains high abundance of lactobacilli compared with C. albicans-carriers. The adoption of Lactobacillus acidophilus INMIA 9602 Er 317/402 leads to changes in gut microbiota composition of FMF patients. It reduces, in particularly, the abundance of enterobacteria in females, and Enteroccocus faecalis in men parallel with reducing the numbers of yeast in gut microbiota of FMF patients. We hypothesize that colchicine treatment changes the already-altered gut microbiota of FMF patients, thereby affecting the regulation of immune system by inhibition of NLRP3 inflammasome. Colchicine could lead to overgrowth of C. albicans in gut microbiota of FMF patients, whereas the Lactobacillus acidophilus INMIA 9602 Er 317/402 works on activation of inflammasome by new changes in gut microbiota of patients.

Project description:We knocked down the Mediterranean fever (MEFV) gene by RNA interference (siRNA) in human myelomonocytic cells that express endogenous pyrin, aiming to identify microRNAs (miRNAs) that are differentially expressed in siMEFV treated cells. The purpose of this study was to better understand the pathophysiology of FMF, through the identification of novel miRNAs involved in the regulation of MEFV.

Project description:Ago2, an essential effector for miRNA function, has been reported to be found in the nucleus together with miRNA. The miRNA-Ago complexes in the nucleus play an important role in regulating gene transcription. We previously have demonstrated the nuclear presence of miR-204-3p in macrophages. Here, we investigated and compared the Ago2 occupancy on the chromosomes upon miR-204-3p overexpression.

Project description:The aim of this study is to discover genes regulated by miR-204. Differential gene expression in HEK-293 cells transfected with miR-204-mimic compared to HEK-293 cells transfected with control oligo (HEK-293 control) was analyzed using the Agilent Human Whole Genome 4x44K gene expression array (Agilent Technologies, Santa Clara, CA). HEK-293 cells were transfected with either miR-204 or a control, and gene expression was analyzed using the Agilent Human Whole Genome 4x44K array. A dye-swap was performed.

Project description:Objective. Colchicine is an alkaloid that is used to alleviate acute gout and to prevent acute attacks of familial Mediterranean fever (FMF). However, it is not beneficial when given during the occurrence of an acute episode of FMF. It is believed that colchicine exerts its anti-inflammatory effect through direct interaction with microtubules. We aim to study the molecular basis of colchicine action by analysing the effect of this drug on global gene expression of HUVEC (human umbilical vein endothelial cell line) cells. Methods. HUVEC cells were exposed to various concentrations of colchicine and were harvested at different time points. Ribonucleic acid was extracted, amplified, reverse transcribed and hybridized to complementary deoxyribonucleic acid microarrrays containing more than 40,000 probes to human expressed sequence tags. This approach enabled us to have a global look at the transcriptional response induced by colchicine treatment. Results. Colchicine changed the expression of many genes in HUVEC cells following exposure to a concentration of 100 ng/ml or higher. Following short exposure (30 or 120 min), colchicine affected genes known to be involved in the cell cycle and its regulation. However, change in expression of genes involved in neutrophil migration or other inflammatory processes were observed mainly after 12 to 24 h. Conclusions. The anti-inflammatory effect of colchicine may be mediated not only through direct interaction with microtubules but also through changes at the transcriptional level. This latter effect apparently requires a higher concentration and a longer time to occur. This can explain the observation that colchicine does not have an immediate effect when given during an acute attack of FMF.

Project description:Introduction: The mechanisms underlying myopia and myopia-related retinopathy remain not fully understood. We proposed to examine the function and underlying mechanisms of miR-204-5p in myopia development. Methods: The miR-204-5p expression level was assessed in the vitreous humor (VH) of a cohort consisting of 11 patients with high myopia (HM) and 16 control patients undergoing retinal surgery. The functional implications of miR-204-5p in ARPE-19 cells were assessed, encompassing cell aggressiveness. Thioredoxin-interacting protein (TXNIP) was found as a possible target of miR-204-5p through mRNA sequencing, and its interaction with miR-204-5p was confirmed employing luciferase assay and western blotting. Furthermore, the miR-204-5p function in regulating oxidative stress was examined by measuring reactive oxygen species (ROS) accumulation. Results: miR-204-5p was found to be significantly reduced in the VH of HM patients. Overexpression of miR-204-5p suppressed cell proliferation, migration, invasion, and apoptosis in ARPE-19 cells. The bioinformatics analysis demonstrated that miR-204-5p can modulate the genes associated with pathways relevant to myopia, including glycosaminoglycan (GAG) degradation, lysosome, and TGF−beta signaling pathway. The direct targeting of miR-204-5p on TXNIP has been confirmed through validation, and its downregulation mediated the miR-204-5p impacts on ARPE-19 cells. Moreover, miR-204-5p overexpression significantly reduced ROS accumulation by targeting TXNIP. Conclusion: Our findings revealed the possible contribution of the miR-204-5p/TXNIP axis in myopia development by regulating oxidative stress, which may provide new targets and novel therapeutic strategies to combat this prevalent and debilitating condition.
