Comparative transcriptome analysis of muscle of zebrafish (Danio rerio) acclimated to different environmental temperatures

We hypothesize that long-term temperature acclimation may alter muscle growth and collagen deposition in zebrafish, thus affecting the flesh texture of fish. Here, comparative transcriptome analysis was conducted to explore the potential molecular mechanism underlying the effects of temperature on flesh texture (collagen depostion, muscle fiber growth, etc) of zebrafish.

We analyzed the differentially expressed genes (DEGs) between muscle of zebrafish acclimated to different temperatures (18°C，28°C，34°C) . Several important DEGs and KEGG pathways were identified to be potentially involved in the temperature-regulated alternation of flesh texture of fish.
