摘要

The sterol regulatory element binding protein-1a (SREBP-1a) is a lipogenic transcription factor that differentially regulates the expression of inflammation-related genes. One of the most profoundly downregulated genes in Srebp-1a-defi-cient mice was recently reported to be the inflammasome sensor Nlrpia (Im et al., 2011). We obtained Srebp-1a-deficient mice to cross with mice containing an Nlrp1a activating mutation to see if the Srebp-1 a deficiency could reduce the incidence of their spontaneous inflammatory disease (Masters et al., 2012). We noticed while breeding the Srebp-1a/Nlrp1 a mutant mice that no pups in any of the first litters had both Srebp-1 a deleted and Nlrp1a mutated on the same allele. This suggested that the genes are in close proximity, and not recombining. Indeed, Srebp-1 a is on chromosome 11: 60, 209, 846, and Nlrp1a is next door at chromosome 11: 71,117, 950.
