Abstract
The expression of JNK1 isoform of cJun-N-terminal kinase in hepatocytes of rats receiving excess of simple carbohydrates dissolved in drinking water was studied by immunohisto-chemical staining and confocal microscopy. In experiment I (60 days), the highest expression of JNK1 was observed in female Wistar rats receiving fructose (the difference with the group receiving a mixture of glucose and fructose was significant, p<0.05, the difference with the control group at the trend level, p=0.077; Mann—Whitney U test). In experiment II (120 days), an increase in JNK1 expression was observed in Wistar rats (males and females) receiving 30% fructose. In Dark Aguti rats (females and males) of comparable age, increased basal level of JNK1 expression was observed in comparison with Wistar rats. Three-way ANOVA showed that JNK1 expression was significantly (p<0.05) associated with consumption of fructose and animal line, but not sex. The level of JNK1 expression corresponded to previously identified changes in the biochemical markers of the metabolic syndrome.
