DNA Methylation-Based Point-of-Care Cancer Detection: Challenges and Possibilities.

DNA Methylation-Based Point-of-Care Cancer Detection: Challenges and Possibilities. Trends Mol Med. 2019 Jun 25;: Authors: Sina AA, Carrascosa LG, Trau M Abstract Eukaryotic cell DNA conserves a distinct genomic methylation pattern, which acts as a molecular switch to control the transcriptional machinery of the cell. However, pathological processes can alter this methylation pattern, leading to the onset of diseases such as cancer. Recent advances in methylation analysis provide a more precise understanding of the consequence of DNA methylation changes towards cancer progression. Consequently, the discoveries of numerous methylation-based biomarkers have inspired the development of simple tests for cancer detection. In this opinion article, we systematically discuss the benefits and challenges associated with the promising methylation-based approaches and develop a point-of-care index to evaluate their potential in terms of point-of-care cancer diagnostics.
