Dietary interventions dramatically affect metabolic disease and lifespan in various aging models. Here, we profiled liver microRNA (miRNA), coding, and long non-coding RNA (lncRNA) expression by high-throughput deep sequencing in mice across multiple energy intake and expenditure interventions. Strikingly, three dietary intervention network design patterns were uncovered: (1) lifespan-extending interventions...
The centromere of many eukaryotes contains highly repetitive sequences marked by methylation of histone H3K9 by Clr4 KMT1 . This recruits multiple heterochromatin proteins, including Swi6 and Chp1, to form a rigid centromere and ensure accurate chromosome segregation. In the absence of heterochromatin, cells show an increased rate of recombination in the centromere, as well as chromosome loss...
