Outline of Final Research Achievements

Citrate-containing dialysate (CD) has been considered to cause post-dialysis fatigue to a lesser extent than acetate-containing dialysate (AD). The aim of this study was to validate from a molecular biological perspective a robust glycogen synthesis effect by qRT-PCR. Normal human hepatocytes (HHpC) were cultured with EMEM and AD (AD/EM) or CD (CD/EM) for 4 h. The cells were then lysed, and the glycogen level, as well as the expression levels of glycogen synthase (GYS2), was measured. The glycogen level in HHpC incubated in CD/EM was 5.8 ± 0.8 μg/g, which was significantly higher than 5.1 ± 0.9 observed when incubated in AD/EM. The expression levels of GYS2 in CD/EM was 1.2 fold of that in AD/EM. In this study, it was found that increased glycogenesis capacity of hepatocytes cultured in CD, compared with AD, causes less fatigue feeling after dialysis, which is due to an increased energy level during dialysis in the presence of CD, and contributes to the energy supply after dialysis.
