Abstract Presenilin (Psn) protein is associated with organismal aging. Mutations in the Psn gene may lead to Alzheimer’s disease (AD), dilated cardiomyopathy (DCM), and many age-dependent degenerative diseases. These diseases seriously affect the quality of life and longevity of the population and place a huge burden on health care and economic systems around the world. Humans have two types of Psn, presenilin-1 (PSEN1) and presenilin-2 (PSEN2). Mutations in the genes encoding PSEN1, PSEN2, and amyloid precursor protein (APP) have been identified as the major genetic causes of AD. Psn is a complex gene strongly influenced by genetic and environmental factors. The… More >

Abstract High-fat diet (HFD) is demonstrated to disturb the bile acid metabolism. The rhythm of bile acid metabolism can also be affected by uridine, whose metabolism exhibits a daily rhythm. However, the mechanism of dynamic uridine administration affecting bile acid during HFD remains unclear. In this study, C57BL/6J mice were fed HFD (the control group; CON) or HFD with oral administration of uridine in the daytime (DUR) and nighttime (NUR) to investigate the mechanism of the effect of uridine on the bile acid. This study showed that the mRNA expression of uridine transporters and circadian clock genes in the jejunum was… More >

Abstract This study aimed to investigate the microRNA expression profile and the characteristics of lipid metabolism in the livers of rats undergoing a high-fat diet. Fifty male Sprague-Dawley (SD) rats were divided into a standard chow group (C group, N = 10) and a high-fat diet group (H group, N = 40). After 12 weeks, the rat body weight, body length, fat mass, and serum lipid concentration were measured. The expression profile of microRNAs and the gene and protein expression levels involved in lipid metabolism in rat liver were detected. Body fat and serum lipid concentrations were all significantly higher in… More >
