In most organisms, superoxide dismutases (SODs) are among the most effective antioxidant enzymes that regulate the reactive oxygen species (ROS) generated by oxidative energy metabolism.
ROS are considered main proximate causes of aging.
However, it remains unclear if SOD activities are associated with organismal longevity.
The queens of eusocial insects, such as termites, ants, and honeybees, exhibit extraordinary longevity in comparison with the nonreproductive castes, such as workers.
Therefore, the queens are promising candidates to study the underlying mechanisms of aging.
Here, we found that queens have higher Cu/Zn-SOD activity than nonreproductive individuals of the termite Reticulitermes speratus.
We identified three Cu/Zn-SOD sequences and one Mn-SOD sequence by RNA sequencing in R.
speratus.
Although the queens showed higher Cu/Zn-SOD activity than the nonreproductive individuals, there were no differences in their expression levels of the Cu/Zn-SOD genes RsSOD1 and RsSOD3A.
Copper (Cu2+ and Cu+) is an essential cofactor for Cu/Zn-SOD enzyme activity, and the queens had higher concentrations of copper than the workers.
These results suggest that the high Cu/Zn-SOD activity of termite queens is related to their high levels of the cofactor rather than gene expression.
This study highlights that Cu/Zn-SOD activity contributes to extraordinary longevity in termites.
