Social relationships are complex and likely involve the multiple neural circuits, including those involved in learning, memory, motivation, and attention. Two neurotransmitter pathways highly involved in these neural circuits are norepinephrine (NE) and the nonapeptides, vasopressin (AVP) and oxytocin (OT). There is extensive research implicating a role for the nonapeptides in trust, sociality, parental care, and romantic relationships. There is little direct evidence for the role of nonapeptides in monogamous relationships in any species other than the prairie vole (Goodson 2013). However, there is evidence that nonapeptides are important in pair bonding for both male and female zebra finches (Lowrey …

Down syndrome (DS) is a chromosomal condition characterized by accelerated aging that has yet to be directly linked to a DNA repair defect. Reduced PolB and unrepaired damage from oxidative stress observed in DS, point toward defective base excision repair (BER). In this study, we report that low PolB transcript correlates with increased markers of senescence. The gene dosage effect of Trisomy 21 is likely the source for PolB downregulation. We show that the HSA21-localized miR-155 overexpression correlates with a decrease in Creb1 and PolB, thus establishing a putative regulatory pathway. Data from the DS mouse model, Ts65Dn, reveal low …
