Mouse methylation clock
Nettet3. jul. 2024 · A four-year-old dog is similar to a 52-year-old human. Then by seven years old, dog aging slows. “This makes sense when you think about it—after all, a nine-month-old dog can have puppies, so ... Given the accuracy of our mouse epigenetic clock to predict chronological age in healthy individuals, we asked whether epigenetic age in the mouse would be affected by gender, diet or other biological interventions. Since it has been reported that DNA methylation shows gender-specific patterns [30], we compared the … Se mer In order to study age-associated DNA-methylation changes in the mouse over a wide range of ages and tissues, we collected liver, lung, … Se mer Having found that methylation at many individual CG sites did change in an age-dependent manner, we decided to generate an epigenetic age predictor in mice (Fig. 2a). In addition to our own datasets, we also … Se mer Given the similarities between our mouse epigenetic age predictor and the previously described human epigenetic clock [6], we asked whether the specific genomic loci described in human could be used to predict age in … Se mer

However, it is not yet clear how DNA methylation affects early embryonic muscle development between goose breeds of different body size. In this study, whole genome bisulfite sequencing …
Nettet14. nov. 2024 · A mouse DNAm multi-tissue clock (YOung Multi-Tissue or YOMT in what follows) was recently developed ( Stubbs et al., 2024 ), which was tuned for tissues of younger mice, for example its mean absolute error, MAE, increased from 2.14 to 4.66 weeks if applied to animals of <20 weeks and 20–40 weeks of age, respectively. Nettet30. mar. 2024 · DNA methylation (DNAm) can affect gene expression, and strong correlations between DNAm patterns and age have been documented in humans and nonhuman vertebrates and used to construct “epigenetic clocks”.
