Key result
Oxytocin induced a biphasic vascular response in rat aortic rings, causing vasorelaxation at low doses via the PI3K/eNOS pathway and vasoconstriction at high doses via ERK1/2 activation.
Why the study?
Oxytocin has demonstrated important cardiovascular protective effects, but its effects on vascular reactivity and the underlying mechanisms remained to be investigated.
Does oxytocin affect vascular reactivity and signaling pathways in HUVECs and rat aorta?
Does oxytocin affect vascular reactivity and signaling pathways in HUVECs and rat aorta?
p-value: p=<0.05
Oxytocin exerts dose-dependent biphasic effects on vascular tone, promoting vasorelaxation at low doses and vasoconstriction at high doses through distinct signaling pathways.
No takes yet. Share an insight, caveat, or question.
Should not change oxytocin use; leaves open human validation of dose-specific vascular pathways.
Xu et al. (2022) studied Vascular reactivity. Oxytocin vs. Control (DMSO or unstimulated) was evaluated on Vascular reactivity (vasorelaxation and vasoconstriction) (p=<0.05). Oxytocin induced a biphasic vascular response in rat aortic rings, causing vasorelaxation at low doses via the PI3K/eNOS pathway and vasoconstriction at high doses via ERK1/2 activation.
