Gene expression profiling of the Tlr2 mutant of zebrafish embryos at 4 days post infection of M. marinum

We use the Tlr2 mutant of zebrafish embryos model to study the transcriptome response to Mycobacterium marinum infection. We injected M.marinum into the caudal vein at 28 hours post fertilization and took samples at 4 days post infection. Overall design: This deep sequence study was designed to determine the gene expression profile in the Tlr2 mutant and heterozygote by M.marinum infection. RNA was isolated at 4 days post infection. Tlr2 mutants and heterozygotes zebrafish embryos were micro-injected into the caudal vein with 150CFU M.marinum, or PBS as a control at 28 hours post fertilization. After injections embryso were transerred into fresh egg water and incubated at 28 degree. At 4 days post infection triplicateds of 10 embryos per condition were snapfrozen in liquid nitogen, and total RNA was isolated using TRIZOL reagent.
