Molecular docking-based design and development of a highly selective probe substrate for UDP-glucuronosyltransferase 1A10
2018
Intestinal and hepatic glucuronidation by the UDP-glucuronosyltransferases (UGTs) greatly affect the bioavailability of phenolic compounds. UGT1A10 catalyzes glucuronidation reactions in the intestine, but not in the liver. Here, our aim was to develop selective, fluorescent substrates to easily elucidate UGT1A10 function. To this end, homology models were constructed and used to design new substrates, and subsequently, six novel C3-substituted (4-fluorophenyl, 4-hydroxyphenyl, 4-methoxyphenyl, 4-(dimethylamino)phenyl, 4-methylphenyl, or triazole) 7-hydroxycoumarin derivatives were synthesized from inexpensive starting materials. All tested compounds could be glucuronidated to nonfluorescen…
Genome-Wide Association Study (GWAS) on Bilirubin Concentrations in Subjects with Metabolic Syndrome: Sex-Specific GWAS Analysis and Gene-Diet Intera…
2019
Although, for decades, increased serum bilirubin concentrations were considered a threatening sign of underlying liver disease and had been associated with neonatal jaundice, data from recent years show that bilirubin is a powerful antioxidant and suggest that slightly increased serum bilirubin concentrations are protective against oxidative stress-related diseases, such as cardiovascular diseases. Therefore, a better understanding of the gene-diet interactions in determining serum bilirubin concentrations is needed. None of the previous genome-wide association studies (GWAS) on bilirubin concentrations has been stratified by sex. Therefore, considering the increasing interest in incorporat…
Sindrome di di Crigler-Najjar tipo 2: due nuove mutazioni missense nel gene UGT1A1.
2009
La sindrome di Crigler-Najjar (CNS) è una malattia molto rara (prevalenza 1/1.000.000 nati) a trasmissione autosomica recessiva, caratterizzata da un incremento cronico e grave di bilirubina sierica indiretta (non coniugata), dovuta alla parziale (tipo 2) o completa (tipo 1) assenza funzionale dell’enzima epatico glucoronosil transferasi UGT1. La malattia si manifesta in età neonatale con un ittero precoce e intenso, dovuto alla presenza di bilirubina non coniugata e l'esame fisico è nella norma; in epoca di sviluppo gli effetti clinici della CNS tipo 1 sono letali in quanto l’eccesso di bilirubina porta inevitabilmente ad una encefalopatia essendo tale pigmento fortemente liposolubile. Le …
