Project description:Since their introduction, epigenetic clocks have been extensively used in aging and human disease research. In this study, we reveal an intriguing pattern: epigenetic age predictions display a 24-hour periodicity. These paradoxical age oscillations can be attributed to variations in blood cell type composition and epigenomes, both of which demonstrate circadian rhythmicity. This discovery emphasizes the significance of factoring-in the time of day to obtain accurate estimates of epigenetic age.

Project description:In our previous study, we found that WBC miRNA may serve as ADHD prediction biomarkers. Therefore, we wonder whether WBC gene expression profile could also serve as ADHD biomarkers. We enrolled ADHD and healthy control subjects, followed by collecting RNA samples from total WBC.
Project description:We comprehensively assessed the total and mitochondrial proteome in the MMTV-NEU-NDL-YD5 murine model of HER2-driven mammary cancer.
