1.
Role of heme oxygenase 1 and human chorionic gonadotropin in pregnancy associated diseases
Gallardo V, Gonzalez M, Toledo F, Sobrevia L
Biochim Biophys Acta Mol Basis Dis . 2019 Aug; 1866(2):165522. PMID: 31376481
Heme oxygenase (HO) is the enzyme that catalyses heme breakdown to biliverdin, carbon monoxide, and ferrous ion. Biliverdin is rapidly converted to bilirubin by biliverdin reductase. HO-1, the inducible HO...

Insulin Induces Relaxation and Decreases Hydrogen Peroxide-Induced Vasoconstriction in Human Placental Vascular Bed in a Mechanism Mediated by Calcium-Activated Potassium Channels and L-Arginine/Nitric Oxide Pathways
Cabrera L, Saavedra A, Rojas S, Cid M, Valenzuela C, Gallegos D, et al.
Front Physiol . 2016 Dec; 7:529. PMID: 27920724
Short-term incubation with insulin increases the L-arginine transport in HUVECs.Short-term incubation with insulin increases the NO synthesis in HUVECs.Insulin induces relaxation in human placental vascular bed.Insulin attenuates the constriction induced...

Insulin reverses D-glucose-increased nitric oxide and reactive oxygen species generation in human umbilical vein endothelial cells
Gonzalez M, Rojas S, Avila P, Cabrera L, Villalobos R, Palma C, et al.
PLoS One . 2015 Apr; 10(4):e0122398. PMID: 25875935
Vascular tone is controlled by the L-arginine/nitric oxide (NO) pathway, and NO bioavailability is strongly affected by hyperglycaemia-induced oxidative stress. Insulin leads to high expression and activity of human cationic...
4.
Insulin-stimulated L-arginine transport requires SLC7A1 gene expression and is associated with human umbilical vein relaxation
Gonzalez M, Gallardo V, Rodriguez N, Salomon C, Westermeier F, Guzman-Gutierrez E, et al.
J Cell Physiol . 2011 Feb; 226(11):2916-24. PMID: 21302286
Insulin causes endothelium-derived nitric oxide (NO)-dependent vascular relaxation, and increases L-arginine transport via cationic amino acid transporter 1 (hCAT-1) and endothelial NO synthase (eNOS) expression and activity in human umbilical...

Hybrid catalytic-DBD plasma reactor for the production of hydrogen and preferential CO oxidation (CO-PROX) at reduced temperatures
Rico V, Hueso J, Cotrino J, Gallardo V, Sarmiento B, Brey J, et al.
Chem Commun (Camb) . 2009 Oct; (41):6192-4. PMID: 19826665
Dielectric Barrier Discharges (DBD) operated at atmospheric pressure and working at reduced temperatures (T < 115 degrees C) and a copper-manganese oxide catalyst are combined for the direct decomposition and...

Vitamin C is an essential antioxidant that enhances survival of oxidatively stressed human vascular endothelial cells in the presence of a vast molar excess of glutathione
Montecinos V, Guzman P, Barra V, Villagran M, Munoz-Montesino C, Sotomayor K, et al.
J Biol Chem . 2007 Apr; 282(21):15506-15. PMID: 17403685
Cellular glutathione levels may exceed vitamin C levels by 10-fold, generating the question about the real antioxidant role that low intracellular concentrations of vitamin C can play in the presence...

Equilibrative nucleoside transporter 1 expression is downregulated by hypoxia in human umbilical vein endothelium
Casanello P, Torres A, Sanhueza F, Gonzalez M, Farias M, Gallardo V, et al.
Circ Res . 2005 Jun; 97(1):16-24. PMID: 15933265
Reduced oxygen level (hypoxia) induces endothelial dysfunction and release of the endogenous nucleoside adenosine. Human umbilical vein endothelium (HUVEC) function in an environment with 3% to 5% O2 and exhibit...
