An assay for beta-alanine transaminase activity in extracts of Drosophila melanogaster has been developed. By use of this assay, the levels of beta-alanine transaminase activity in several strains of flies has been examined as a function of developmental age. The black mutation shows elevated levels of activity compared to wild type, while suppressor of black strains show decreased levels compared to wild type.

Scopoleitin (SP), a bioactive compound from many edible plants and fruits, exerts a wide range of biological activities, however the role and mechanism of SP in acetaminophen (APAP)-induced hepatotoxicity remains unclear. In this study, we verified the protective effect of SP on APAP-induced liver injury (AILI) hepatotoxicity and explore the underlying molecular mechanisms. Here, we showed that SP alleviated AILI by reducing serum alanine transaminase (ALT) and aspartate aminotransferase (AST) levels, hepatic histopathological damage, inflammation, and liver cell apoptosis.

Importance: The neuropathological links underlying the association between changes in liver function and AD have not yet been clearly elucidated.
Objective: We aimed to examine the relationship between liver function markers and longitudinal changes in Alzheimer's disease (AD) core pathologies.
Design: Data from the Korean Brain Aging Study for the Early Diagnosis and Prediction of Alzheimer's Disease, a longitudinal cohort study initiated in 2014, were utilized.

Introduction: Molecular alterations in the PI3K/AKT and Ras/Raf/MEK/ERK pathways are frequently observed in patients with endometrial cancers. However, mTOR inhibitors, such as temsirolimus, have modest clinical benefits. In addition to inducing metabolic changes in cells, metformin activates AMPK, which in turn inhibits the mTOR pathway.

Aims: Carboxylesterase (Ces)1f is implicated in protection against hepatic inflammation, but it is unclear whether the enzyme has an influence in polarization of Kupffer cells (KCs), the innate immune cells mediating hepatic inflammatory injury including acute liver failure (ALF). In the present study, we aim to explore KC polarization induced by Ces1f in mice with lipopolysaccharide/D-galactosamine (LPS/D-GalN)-induced ALF. We adopted a novel delivery system, β-1,3-D-glucan-encapsulated Endoporter-siRNA particles, to specifically target KC Ces1f knockdown via tail vein injection in mice.
