Abstract:

This article utilizes the deep efficient peptide sequencing and quantification proteomics method in conjunction with isobaric tags for relative and absolute quantitation to perform differential proteomic analysis of proteins in naturally shed hair samples collected at 24, 48, 72 and 96 h after birth in newborns. Among the four hair samples collected within 96 h after birth, a total of 1735 proteins were identified, with a large number of proteins showing dynamic changes in expression, involving embryonic development, energy metabolism, and neural pathways. These findings indicate that hair samples, as a novel clinical specimen, can reflect the early and drastic physiological and molecular changes in newborns, providing new insights for non-invasive diagnosis and early disease screening in newborns.
