Nitric oxide (NO) is a highly reactive molecule, generated through metabolism of L-arginine
by NO synthase (NOS). Abnormal NO levels in mammalian cells are associated with multiple …

Normal human pregnancy is considered a state of enhanced oxidative stress. In pregnancy,
it plays important roles in embryo development, implantation, placental development and …

S-Nitrosylation is a redox-mediated posttranslational modification that regulates protein
function via covalent reaction of nitric oxide (NO)-related species with a cysteine thiol group …

Wingless ligands, a family of secreted proteins, are critically involved in organ development
and tissue homeostasis by ensuring balanced rates of stem cell proliferation, cell death and …

BACKGROUND During pregnancy, maternal uterine spiral arteries (SAs) are remodelled
from minimal-flow, high-resistance vessels into larger diameter vessels with low resistance …

Many of the best-studied actin regulatory proteins use non-covalent means to modulate the
properties of actin. Yet, actin is also susceptible to covalent modifications of its amino acids …

Nitric oxide (NO) is one of the most pleiotropic signaling molecules at systemic and cellular
levels, participating in vascular tone regulation, cellular respiration, proliferation, apoptosis …

Nitric oxide (NO) is gaining increasing attention as a regulator of diverse (patho-)
physiological processes in plants. Although this molecule has been described as playing a …

The available data support the hypothesis that L-arginine or L-citrulline supplementation
would be suitable for implementation in resource-constrained settings and will enhance …

Nitric oxide (NO) and matrix metalloproteinase 9 (MMP-9) levels are found to increase in
inflammation states and in cancer, and their levels may be reciprocally modulated …
