Description

technical field [0001] The present invention relates to an epigenetic method for obtaining information that can be used to determine the effect of sunscreen use on an individual's skin. Background technique [0002] DNA methylation is an epigenetic determinant of gene expression. Patterns of CpG methylation are heritable, tissue-specific, and correlate with gene expression. A consequence of methylation, especially when located in gene promoters, is often gene silencing. DNA methylation is also associated with other cellular processes, including embryonic development, chromatin structure, genomic imprinting, somatic X chromosome inactivation in females, repression of foreign DNA transcription and transposition, and the timing of DNA replication. When a gene is highly methylated, it is less likely to be expressed. Therefore, identifying 5-meC-containing sites in the genome is important for understanding cell type-specific gene expression programs and how gene expression pro...
