Characterization of sgk, a novel member of the serine/threonine protein kinase gene family which is transcriptionally induced by glucocorticoids and serum.
A novel member of the serine/threonine protein kinase gene family, designated sgk, for serum and glucocorticoid-regulated kinase, was identified in a differential screen for glucocorticoid-inducibleExpand

LC/MS characterization of phenolic constituents of mate (Ilex paraguariensis, St. Hil.) and its antioxidant activity compared to commonly consumed beverages
Mate is a tea-like beverage widely consumed in South America, prepared from the dried leaves of Ilex paraguariensis, St Hil. The total polyphenols (PP) and antioxidant activity of mate infusions andExpand

Immediate-early transcriptional regulation and rapid mRNA turnover of a putative serine/threonine protein kinase.
Serine/threonine protein kinases are important regulators of diverse cellular processes including metabolism, proliferation, and differentiation. We have previously identified the cDNA for a 49-kDaExpand

Cocoa flavonoids attenuate high glucose-induced insulin signalling blockade and modulate glucose uptake and production in human HepG2 cells.
Insulin resistance is the primary characteristic of type 2 diabetes. Cocoa and its main flavanol, (-)-epicatechin (EC), display some antidiabetic effects, but the mechanisms for their preventiveExpand

Effect of coffee melanoidin on human hepatoma HepG2 cells. Protection against oxidative stress induced by tert-butylhydroperoxide.
Soluble high-molecular weight fraction (named melanoidin) from coffee brew was isolated by ultrafiltration, subsequently digested by simulating a gastric plus pancreatic digestive condition andExpand

Glucocorticoids induce a G1/G0 cell cycle arrest of Con8 rat mammary tumor cells that is synchronously reversed by steroid withdrawal or addition of transforming growth factor-alpha.
Con8 mammary tumor cells are an epithelial cell line derived from the 7,12-dimethylbenz(alpha)anthracene-induced 13762NF rat mammary adenocarcinoma. The synthetic glucocorticoid dexamethasoneExpand

Protein tyrosine phosphatase 1B modulates GSK3β/Nrf2 and IGFIR signaling pathways in acetaminophen-induced hepatotoxicity
Acute hepatic failure secondary to acetaminophen (APAP) poisoning is associated with high mortality. Protein tyrosine phosphatase 1B (PTP1B) is a negative regulator of tyrosine kinase growth factorExpand

Effects of undernutrition and diabetes on serum and liver mRNA expression of IGFs and their binding proteins during rat development.
The purpose of the present study was to investigate the influence of nutrients and insulin on IGFs and their binding proteins (IGFBPs) during the fetal and neonatal periods of three rat populations:Expand

Antidiabetic actions of cocoa flavanols.
Prevention of diabetes mellitus type 2 (DMT2) through the diet is receiving a growing interest and cocoa because of its polyphenolic compounds, mainly flavanols, has become an important potentialExpand

Effects of refeeding of undernourished and insulin treatment of diabetic neonatal rats on IGF and IGFBP.
The effect of refeeding and insulin treatment of undernourished and diabetic neonatal rats, respectively, on the regulation of insulin-like growth factor (IGF) and insulin-like growth factor bindingExpand
