Core Tip
Core tip: Accidents of nature leading to rare genetic diseases can provide important insights into the molecular and cellular foundations of related common diseases. Various genetic anomalies at chromosome 6q24 manifest with life-threatening transient neonatal diabetes mellitus (TNDM1). All of these genetic defects share overexpress-ion of the maternally imprinted transcriptional regulator ZAC1. Genome-wide expression profiling identified a number of downstream target genes sharing a critical role in insulin secretion, β-cell proliferation, and survival. Importantly, Zac1 overexpression in β-cells spares the effects of G-protein signaling on insulin secretion opening the prospect for tailored therapy in TNDM1 patients.
