BACKGROUND Oxidative stress is responsible for generating DNA lesions and the 8-oxoguanine (8-oxoG) is the most commonly lesion found in DNA damage. When this base is incorporated during DNA replication, it could generate double-strand DNA breaks and cellular death. MutT enzyme hydrolyzes the 8-oxoG fro...
Hormones regulate hepatic gene expressions to maintain metabolic homeostasis. Ectonucleotide pyrophosphatase/phosphodiesterase 1 has been thought to interfere with insulin signaling. To determine its potential role in the regulation of metabolism, we analyzed its gene (Enpp1) expression in the liver of r...
ABSTRACT Background. The prevalence of two functional polymorphisms (rs1127354 and rs7270101) of the inosine triphosphatase (ITPA) gene associated with ribavirin-induced hemolytic anemia (RIHA) during antiviral therapy for hepatitis C virus (HCV) infection varies by ethnicity. In Mexico, the distributi...
El presente trabajo involucra el estudio del sistema purinérgico mediante la purinérgico mediante la purificación y la caracterización bioquimica de la ecto-enzima E-NPP3 soluble, la cual modula la activación de los receptores purinérgicos mediante la hidrólisis de los nucleótidos extracelulares....
Várias propriedades biológicas têm sido atribuídas ao hidróxido de cálcio, tais como: açäo antiinflamatória, açäo antimicrobiana, solvente de matéria orgânica, inibiçäo da reabsorçäo e induçäo de reparo mineralizado. Neste trabalho, estas propriedades säo discutidas baseado em achados...
