Project description:This study examines the transcriptomic response of biofilms of the PAH-degrading Sphingomonas sp. LH128 on solute stress when actively degrading and growing on the PAH compound. To address the effect of solute stress on bacterial physiology and transcriptomic response, NaCl was used as osmolyte. Both acute and chronic solute stress was invoked to assess differences in short-term and long-term responses.
Project description:Lack of change in microRNA expression in adult mouse liver following treatment with benzo(a)pyrene (BaP), as detected using Agilent miRNA arrays. We have investigated the effect of exposure to 150 mg/kg benzo(a)pyrene (BaP) for 3 days on mRNA and miRNA expression levels in adult mouse liver. We used Agilent miRNA array platforms to assess effects of BaP exposure on miRNA expression levels. Our results indicate a distinct lack of effect of BaP of miRNA expression, despite widespread changes in mRNA levels. Keywords: Toxicology, miRNA
