Pancreatic islet expression profiling in diabetes-prone C57BLKS/J mice reveals transcriptional differences contributed by DBA loci, including Plagl1 and Nnt

Abstract excerpt

BACKGROUND: C57BLKS/J (BLKS) mice are susceptible to islet exhaustion in insulin-resistant states as compared with C57BL6/J (B6) mice, as observed by the presence of the leptin receptor (Lepr) allele, Leprdb/db. Furthermore, DBA2/J (DBA) mice are also susceptible to beta-cell failure and share 25% of their genome with BLKS; thus the DBA genome may contribute to beta-cell dysfunction in BLKS mice. RESULTS: Here we...
