ING5 and dermatitis: Although the majority of ING5 KO and WT animals unaffected by dermatitis had similar lifespans, living to, on average 130 weeks, 13.1% of ING5 KO animals (17 of 129) versus 2.3% of WT animals (3 of 132) that were 18 months or older developed enlarged lymph nodes, spleens and pancreata as shown in (Fig 9), and were subsequently euthanized.
