Bat genome study links lifespan to immune defenses and cell death

The short version

• Researchers published an analysis of eight Myotis bat genomes in Nature, linking lifespan directly to immune system traits.[ScienceDaily]
• Longer-lived bat species showed higher levels of cancer-fighting genes, according to study findings.[ScienceDaily]
• Under toxic chemical stress, little brown bat cells triggered genes that drive cell destruction rather than DNA repair.[ScienceDaily]
• Myotis bats maintain an unusually high count of genes generating proteins that interact with DNA viruses.[ScienceDaily]

Key facts

• An analysis of eight Myotis bat genomes published in Nature demonstrated a relationship between lifespan and immune function.[ScienceDaily]
• Longer-lived bats possess elevated levels of genes tied to fighting cancer.[ScienceDaily]
• Little brown bat cells exposed to toxic substances boosted the activity of genes causing cell death rather than DNA repair.[ScienceDaily]
• Myotis bats exhibit an unusually large collection of genes that produce proteins interacting with DNA viruses.[ScienceDaily]
