The effects of temperature reduction on gene expression and oxidative stress in skeletal muscle from adult zebrafish

Seasonal Changes in Hepatic Gene Expression Reveal Modulation of Multiple Processes in Rainbow Smelt (Osmerus mordax)

“…For this reason, transcriptional responses to cold temperature are likely to involve a stress (heat shock) response in addition to adaptive changes; however, the adaptive changes remain informative. In the zebrafish (Danio rerio), temperature shift from 28°C to 18°C for a year increased the expression of genes involved in alleviating oxidative stress (Malek et al 2004). A further study in which zebrafish gills were more specifically examined and for a shorter length of time (1-30 days) showed differential regulation of several genes involved in metabolism (Chou et al 2008).…”

Net superoxide levels: steeper increase with activity in cooler female and hotter male lizards

“…However, more recent work suggests that this is an oversimplification. A microarray study of the expression of 15,512 genes in another ectotherm, the zebrafish (Danio rerio), at 28 versus 18°C, revealed that 'cold fish' upregulated >600 genes more than 1.7-fold and that these genes over-represented two functional gene groups, 'oxygen and reactive oxygen species metabolism' and 'response to oxidative stress' (Malek et al, 2004). Thus, a simplistic relationship between body temperature and genome-wide gene expression level was refuted.…”

Effect of developmental temperature on swimming performance of zebrafish (Danio rerio) juveniles

“…Besides swimming performance, it has been shown to affect growth, metabolism, time of hatching (Herzig and Winkler 1986), development (Herzig and Winkler 1986;Fukuhara 1990;Polo et al 1991;Gibson and Johnston 1995;Lein et al 1997), yolk absorption (Fukuhara 1990), muscle ontogeny and development (Johnston 1981(Johnston , 1993ontogeny of internal organs (Fukuhara 1990;Gibson and Johnston 1995), external morphology (Lindsey 1988;Wimberger 1992;Tudela 1999;Koumoundouros et al 2001a;Pakkasmaa and Piironen 2001;Cabral et al 2003;Silva 2003;Turan 2004), meristic characters (Turan 2004), appearance of skeletal deformities (Polo et al 1991;Koumoundouros et al 2001b), sex determination (Baroiller et al 1999;Pavlidis et al 2000;Koumoundouros et al 2002a) and the overall survival (Fukuhara 1990;Lein et al 1997) and lifespan of fish (Malek et al 2004). Although the effect of swimming temperature on the performance of fish has been studied thoroughly and in a wide range of species, there are only a few studies focusing on the impact of rearing temperature on the swimming performance of adult fish (i.e.…”
