We established that acute adrenergic receptor stimulation in β-cells suppresses oxidative metabolism. This effect provides the basis for understanding how CAs reduce cell proliferation. Furthermore, the effects of acute CA on Min6 cells were distinguished from chronic CA culture using proteomics. Together, the RNAseq, qPCR and proteomic studies support a role for adrenergic receptor signaling in the regulation of proliferaton in β-cells. This work describes the genetic and proteomic profile underlying chronic adrenergic signaling and identifies CA independent suppression of β-cell growth and metabolism. Through the use of multiple models and comparative bioinformatics, we refined the list of molecular dysfunctions associated with the IUGR pathology to a set of specific and testable adrenergic targets.Type
