Project description:To search the methylation of genes which were associated with tuberculosis infecion We used the microarrays to detail the methylation of gDNA between with the tuberculosis infection and without the tuberculosis in monozygous twins

Project description:DNA Methylation was analyzed in tuberculosis patients without HIV at baseline and 6 months after completion of successful therapy. DNA methylation was also evaluated in TB patients with HIV and in healthy controls without Tuberculosis. 500ng of gDNA was bisulfite treated prior to running the Illumina Infinium MethylEPIC array
Project description:Genome wide DNA methylation profiling in the blood between Pulmonary tuberculosis patient's and normal people's who have genetic relationship wtih each other.
Project description:In this study, we have investigated the relationship between genome-wide DNA methylation pattern and HIV infection using the methylated DNA immunoprecipitation - microarray method. A pair of monozygotic twins was recruited: one of the twins was infected with HIV while the other was not. The immunoprecipitated CpG-methylated DNA from HIV positive subject (test) and from HIV negative subject (input control) were labelled with Cy5 and Cy3 respectively

Project description:Knowing when a person was infected with Mycobacterium tuberculosis (M.tb) is critical as recent infection is the strongest clinical risk factor for progression to TB disease in immunocompetent individuals. However, time since M.tb infection is very difficult to determine in routine clinical practice. We determined whether DNA methylation patterns in the blood correlate with time since M.tb infection or exposure to develop a biomarker for recent exposure. As proof of concept, we found a DNA methylation signature that is present during early infection of mice that persists for at least 5 months post-infection.
Project description:Human intelligence demonstrates one of the highest heritabilities among human quantitative traits. Phenotypically discordant monozygotic twins provide a way to identify loci reponsible for the phenotypical differences. We performed comprehensive DNA methylation analysis in monozygotic twins manifesting differences in IQ scores. Genes with significantly different methylation status are considered as candidates related to human intelligence.
