Epigenome analysis of female identical twins

ABSTRACT: Genome wide DNA methylation profiling of blood samples from eight female identical twins of Han Chinese for forensic age prediction, age 21 to 32. The Illumina Infinium HumanMethylation450 BeadChip was used to obtain DNA methylation profiles across approximately 485,000 CpGs at a single-nucleotide resolution. Samples included 8 pairs of identical female twins of Han Chinese.

Circulating microRNAs and life expectancy among identical twins

Project description:Objective: To characterize miRNAs in 41-year archived plasma in relation to life expectancy independent of genes. Method: Plasma miRNAs from nine identical male twins were profiled using next-generation sequencing. Results: The average absolute difference in the minimum life expectancy was 9.68 years. Intra-class correlation coefficients were above 0.4 for 50% of miRNAs. Comparing deceased twins with their alive co-twin brothers, the concentrations were increased for 34 but decreased for 30 miRNAs. Conclusion: Identical twins discordant in life expectancy were unlike in the majority of miRNAs, suggesting that environmental factors are pivotal in miRNAs related to life expectancy.

Epigenome analysis of male identical twin pairs discordant for sexual orientation, age 21 to 55.

Project description:Genome wide DNA methylation profiling of saliva samples from male identical twins discordant for sexual orientation, age 21 to 55. The Illumina Infinium 27k Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation profiles across approximately 27,000 CpGs in bisulfite converted DNA. Samples included 34 pairs of identical twins and one set of identical triplets, and 13 hybridisations were technical replicates of a selection of those samples.

Proteomic Analysis of Hair Shafts from Monozygotic Twins: Expression Profiles and Genetically Variable Peptides

Project description:Forensic association of hair shaft evidence with individuals is currently assessed by comparing mitochondrial DNA haplotypes of reference and casework samples, primarily for exclusionary purposes. Present work tests and validates more recent proteomic approaches to extract quantitative transcriptional and genetic information from hair samples of monozygotic twin pairs, which would be predicted to partition away from unrelated individuals if the datasets contain identifying information. Protein expression profiles and polymorphic, genetically variant hair peptides were generated from 10 pairs of monozygotic twins. Profiling using the protein tryptic digests revealed that samples from identical twins were considerably more alike in profile than unrelated individuals among the twins. The data did not indicate that the degree of difference within twin pairs increased with age. In parallel, data from the digests were used to detect genetically variant peptides that result from common non-synonymous single nucleotide polymorphisms in genes expressed in the hair follicle. Compilation of the variants permitted sorting of the samples by hierarchical clustering, permitting accurate matching of twin pairs. The results demonstrate that genetic differences are detectable by proteomic methods and provide a framework for developing quantitative statistical estimates of personal identification that increase the value of hair shaft evidence.
