The Effect of Eight Weeks of Voluntary and Forced Endurance Training and Royal Jelly Consumption on NF-κB Gene Expression and Antioxidant Agents in Trimethyltin-Treated Alzheimer's Rats

Alzheimer's disease causes hippocampal degeneration, memory loss, and dementia. However, the effect of voluntary and forced endurance training and royal jelly consumption on this disease is not clear.

In this study, the effect of eight weeks of voluntary and forced endurance training and consumption of Royal Jelly (RJ) on NF-κB gene expression and antioxidant factors were investigated in trimethyltin (TMT)-treated Alzheimer’s rats.

After induction of Alzheimer's disease with TMT, 60 male rats were randomly divided into eight groups, including: first and last week slaughtered Alzheimer's rats control, voluntary training (VT), forced swimming training (ST), sham, voluntary training + RJ consumption (VT + RJ), forced swimming training + RJ Consumption (ST + RJ),  and Royal Jelly Consumption (RJ) groups. Also, 12 rats were placed equally in the first and last week slaughtered healthy control groups. The VT and ST groups were placed in a spinning wheel and a special swimming pool for rodents respectively, for eight weeks, and three 60-minute sessions per week using the overload principle. The RJ groups peritoneally received 100 mg/kg/day of royal jelly for eight weeks. One-way ANOVA was used to statistically analyze the values ​​of Malondialdehyde (MDA), Total Antioxidant Capacity (TAC), Beta 2 Microglobulin (B2m), and NF-κB.

TAC gene expression in the hippocampal tissue of ST and VT groups was significant compared with the healthy group (P = 0.02), but MDA gene expression (P=0.165), B2m (P=0.060), and NF-κB (P=0.069) were not significant.

In general, voluntary and forced endurance training and Royal Jelly consumption improve the antioxidant gene expression in the hippocampal tissue of TMT-treated Alzheimer's rats.
