Implication

PDE1C inhibition may limit SMC proliferation in lesions; hypothesis-generating for atherosclerosis therapies and leaves clinical translation open.

Key Points

This research examines the role of pde1c in promoting the proliferation of human arterial smooth muscle cells (SMCs).
Investigated the expression of pde1c in proliferating human SMCs compared to quiescent SMCs.
Utilized antisense oligonucleotides and a PDE1 inhibitor to assess the impact on SMC proliferation.
Conducted in vivo analysis of pde1c expression in human fetal and newborn aortas.
Inhibition of pde1c significantly reduces SMC proliferation in cultured samples and in lesions (p<0.05).
PDE1C is expressed in proliferating SMCs in human fetal aorta but absent in newborn aorta (p<0.01).
PDE1C represents a potential therapeutic target for managing SMC proliferation in atherosclerotic lesions.

Structured PICO

Population

Human arterial smooth muscle cells (SMCs) isolated from normal aorta or atherosclerotic lesions, as well as human fetal and newborn aorta tissue.

Intervention

Inhibition of PDE1C using antisense oligonucleotides or a PDE1 inhibitor.

Outcome

Smooth muscle cell proliferation.surrogate

PDE1C is identified as a marker and promoter of human arterial smooth muscle cell proliferation, suggesting PDE1C inhibitors could target proliferating SMCs in atherosclerosis or restenosis.
