“…Therefore, the absence of a response in mean ROS production under the experimental conditions could be interpreted as an increase in ROS production, but removal of most of the ROS by cellular-level mechanisms before it had been reduced by the marker. Such mechanisms include the ROS scavengers superoxide dismutase, glutathione reductase and catalase [9][10][11], and possibly one or more globins that have also been implicated in ROS regulation [13,50].…”

Reactive oxygen species production and discontinuous gas exchange in insects

While biochemical mechanisms are typically used by animals to reduce oxidative damage, insects are suspected to employ a higher organizational level, discontinuous gas exchange mechanism to do so. Using a combination of real-time, flow-through respirometry and live-cell fluorescence microscopy, we show that spiracular control associated with the discontinuous gas exchange cycle (DGC) in Samia cynthia pupae is related to reactive oxygen species (ROS). Hyperoxia fails to increase mean ROS production, although minima are elevated above normoxic levels. Furthermore, a negative relationship between mean _ V CO 2 and mean ROS production indicates that higher ROS production is generally associated with lower _ V CO 2 . Our results, therefore, suggest a possible signalling role for ROS in DGC, rather than supporting the idea that DGC acts to reduce oxidative damage by regulating ROS production.

“…Recently, a hemoglobin gene has been detected in Drosophila (Burmester and Hankeln 1999) and in Apis (Hankeln, Klawitter, Kra¨mer and Burmester 2006), terrestrial insects that have no difficulty with oxygen supply or energy (ATP) shortages for flight activity. The physiological role of Plecoptera hemocyanin, which is present at low concentrations, is not well understood.…”

Hemocyanin is a respiratory protein that occurs in the main lineages of Arthropoda. In insects hemocyanin is presently known in many orders. Recently, a functional hemocyanin has also been found in the Plecoptera. Further studies have revealed that hemocyanin seems to be not uniformly distributed within this order. In this paper we report additional data, obtained with RT-PCR sequencing, on the presence of hemocyanin in different stonefly species. In addition, we summarise the present knowledge about the distribution of hemocyanin in the Plecoptera. Biological aspects such as larval size, life cycle length, trophic roles and environmental induction are discussed as possible factors that may be correlated with the presence or absence of hemocyanin in the studied species.

“…In Drosophila, three hemoglobin-like genes, glob1-3, have been identified (Burmester and Hankeln, 1999;Hankeln et al, 2002;Burmester et al, 2006). Among them, glob1 shows the highest expression and is mainly expressed in the tracheal system.…”

“…In Drosophila, three hemoglobin-like genes (glob1, glob2, and glob3) have been characterized (Burmester and Hankeln, 1999;Hankeln et al, 2002;Burmester et al, 2006). Hemoglobin-like genes have also been characterized from Apis mellifera , Anopheles gambiae , and Aedes aegypti .…”
