Interpretive Summary: Lipopolysaccharide (LPS) is a major cell wall component of gram-negative bacteria. LPS is heat-stable endotoxin functioning in protection of gram-negative bacteria against the action of bile salts and lipophilic antibiotics. It plays a key role in septic shock in humans by inducing a strong immune response in normal mammalian cells. It is well documented that the bacterial endotoxin LPS rapidly stimulates TTP gene expression at both mRNA and protein levels but less is known about its effect on other TTP family gene expression. The objective was to evaluate LPS effects on gene expression involved in inflammatory responses, lipid biosynthesis, glucose transport and insulin signaling pathway in mouse macrophages. This technical note describes the dataset of LPS on relative levels of 27 mRNAs in mouse RAW264.7 macrophages generated by the SYBR Green qPCR method.

Technical Abstract: Lipopolysaccharide (LPS) is a major cell wall component of gram-negative bacteria. It is well documented that the bacterial endotoxin LPS rapidly stimulates TTP gene expression at both mRNA and protein levels but less is known about its effect on other TTP family gene expression. The objective was to evaluate LPS effects on gene expression involved in inflammatory responses, lipid biosynthesis, glucose transport and insulin signaling pathway in mouse macrophages. Mouse RAW264.7 macrophages were treated with multiple concentrations of LPS for 2-24 h. qPCR analyzed the expression of 27 genes coding for anti-inflammatory tristetraprolin family (TTP/ZFP36), proinflammatory cytokine, lipid biosynthesis (DGAT), glucose transporter (GLUT) and insulin signaling genes. This technical note describes the dataset of LPS on relative levels of 27 mRNAs in mouse RAW264.7 macrophages generated by the SYBR Green qPCR method.
