The indicative value of the hsp70 stress response as a marker for metal effects in Oniscus asellus (Isopoda) field populations: variability between populations from metal-polluted and uncontaminated sites

Cross tolerance in beet armyworm: long-term selection by cadmium broadens tolerance to other stressors

“…There are data suggesting that HSP70 level changed in relation to the exposure duration (Eckwert and Köhler 1997). In the studies conducted on two Daphnia magna clones which differed in Cd sensitivity and HSP70 level, it was demonstrated that high HSP70 level did not reassure the increase of tolerance to Cd and heat shock.…”

“…Further studies have shown that their expression can vary also in response to many other stressing factors (Eckwert and Köhler 1997;Pyza et al 1997;Köhler et al 1999; Knigge and Köhler 2000;Köhler et al 2000;KarounaRenier and Zehr 2003;Arts et al 2004;Haap and Köhler 2009;Jiang et al 2012;Haap et al 2016). There are even opinions that all known stressors may induce HSP expression (Feder and Hofmann 1999).…”

“…In the case of the latter concept there are authors who discuss the changes in HSP concentration at the level of (micro)evolution and analyze it in relations to possible trade-off between HSP induction and other protective mechanisms as well as the general fitness of the organism (Feder and Hofmann 1999). Developmental stage, sex, nutritional status, age and, possibly, acquired tolerance may also be the source of variation in HSP expression (Eckwert and Köhler 1997;Pyza et al 1997;Köhler et al 1999;Knigge and Köhler 2000;Köhler et al 2000;Karouna-Renier and Zehr 2003;Arts et al 2004). The present study may contribute to the explanation of the mechanisms of increased tolerance of invertebrates to chronic vs. acute as well as single vs. joint xenobiotics, connected with HSP70 level.…”

Heat shock response: hsp70 in environmental monitoring

“…Owing to their responsiveness to diverse forms of stress, the stress proteins have undergone widespread application in biomonitoring and environmental toxicology [5,[34][35][36][37][38][39][40][41]. As members of the Hsp70 are often the prominent proteins to be expressed following environmental insults, these stress proteins are, therefore, very useful indicators of cellular aggression, and have been used to monitor the impact of environmental factors on various animal species [42][43][44][45] as well as in in vitro models [28,37,41,46,47]. Hsp70 is the target molecule or molecule under investigation because it simultaneously takes part in defense, repair, or detoxification machinery of the cell and becomes a direct and specific indicator of cellular stress [30,[48][49][50][51].…”

An intron-containing, heat-inducible stress-70 gene in the millipede Tachypodoiulus niger (Julidae, Diplopoda)

“…However, depending on the particular traits, tissue function and developmental stage of the species in question, as well as, of course, the type of stressor and the tolerance towards it variations in the basal stress-70 level and the induction of hsp70 are to be expected (e.g. Eckwert and Köhler 1997;Arts et al 2004). Particularly, the interdependency between adaptations to stressful environmental conditions and the constitutive hsp70 expression and the potential for induction of hsp70 may be complex and variable according to the ecophysiological context.…”
