Gene expression accompanying the promotion of hepatocellular carcinoma by intestinal microbiota and Tlr4 in mice.

The effect of Tlr4P712H mutation (rendering TLR4 non-functional), or gut-sterilization by antibiotics, on the induction of tumorgenesis by CCl4 and diethylnitrosamine (DEN) was characterized. Affymetrix Mouse 430 2.0 gene expression measurements were used to characterize the transcriptomic basis of the effects of the above treatments and genotypes on tumorgenesis.
