After California's Humboldt wildfires ravaged thousands hectares of land in June 2008, sending a blanket of smoke across California, Miller, who heads the respiratory diseases unit at the California National Primate Research Center, saw the opportunity for a long-term study. The DMRs were annotated to genes significantly enriched for synaptogenesis signaling, protein kinase A signaling, and a variety of immune processes, and some DMRs significantly correlated with gene expression differences. According to the Centers for Disease Control and Prevention (CDC), the best way to protect yourself is to "reduce your exposure to wildfire smoke, for example, by seeking cleaner air shelters and cleaner air spaces.
