Research in the Beuve laboratory focuses on cell-cell communications and more
precisely, on pathways that involved the two major second messengers, cAMP and cGMP and
the gaseous molecule nitric oxide (NO). Our research program focuses on 2 main
a) understanding the mechanisms of modulation of soluble guanylyl cyclase (GC1), a heme
containing enzyme that produces cGMP in response to activation by nitric oxide (NO) and
b) the role of GC1 S-nitrosation in cells.
Physiologically, the NO-cGMP signaling pathway is critically involved in vascular
homeostasis via smooth muscle relaxation and in inhibition of platelet aggregation, and
in synaptic plasticity in the nervous system. Pathophysiologically, dysfunction of this
pathway is linked to increased risk of myocardial infarction and is involved in the
development of atherosclerosis, hypercholesterolemia, hypertension, erectile
dysfunction and diabetes mellitus (all characterized by impairment in vascular
reactivity) as well as neurological disorders and retinal degeneration.
We discovered that GC1 is desensitized by S-nitrosation (addition of NO moiety to the
free thiol of cysteine) and investigated the molecular mechanism by which S-nitrosation
affects GC1 activity and the transduction of NO activation. We also found that GC1
forms a complex with thiol-redox proteins, protein disulfide isomerase (PDI) and
thioredoxin 1 (Trx1) and that this association is thiol redox-based. We further
explored the role of the multiple and conserved cysteines (Cys) of GC1 and found that
GC1 could potentially forms disulfide bond, an unexpected post-translational
modification for a cytosolic enzyme.
We use biochemistry, cell biology and integrative approaches to explore the mechanism
of thiol-dependent modulation of GC1 and its involvement in vascular dysfunction under
oxidative and nitrosative stress. Our current research areas are
- Molecular mechanisms of thiol-based modulation of GC1
- Function of the interaction between GC1 and thiol-redox proteins
- Functional studies of thiol-dependent impairment of GC in oxidative pathophysiologies
