Recent advancements in integrated diagnostics and biomarkers have significantly enhanced our understanding of various diseases. In the realm of skin pigmentation, a study applied massively parallel reporter assays to screen 1,157 candidate variants, identifying 165 single-nucleotide polymorphisms that exhibit differential regulatory activities. This research combined Hi-C, genome editing, and melanin assays to elucidate the regulatory elements affecting melanin levels and human skin color (ref: Feng doi.org/10.1038/s41588-023-01626-1/). In the context of colorectal cancer, a novel multimodal epigenetic sequencing analysis (MESA) was developed to capture diverse epigenetic features in cell-free DNA (cfDNA), demonstrating its potential for non-invasive cancer detection (ref: Li doi.org/10.1186/s13073-023-01280-6/). Furthermore, the identification of persistent complement dysregulation in individuals with Long Covid through multimodal proteomics highlights the role of immune mechanisms in chronic conditions (ref: Cervia-Hasler doi.org/10.1126/science.adg7942/). These studies collectively underscore the importance of integrating genomic, epigenetic, and proteomic approaches to enhance diagnostic accuracy and treatment monitoring across various diseases.
