摘要:

利用一种深度高效肽段鉴定蛋白质组学方法, 结合相对定量同位素标记, 对新生儿出生后24, 48, 72和96 h的自然掉落毛干样本中的蛋白质进行差异蛋白质组分析. 在新生儿出生后96 h内采集的4份毛干样本中, 共鉴定到1735个蛋白, 有大量蛋白表达量表现出动态变化, 涉及胚胎发育、 能量代谢及神经系统相关通路. 结果表明, 毛干作为新颖的临床样本, 能够反映新生儿早期剧烈的生理和分子变化过程, 为新生儿的无创诊断和早期疾病筛查提供了新的思路.

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.
