In contrast to the considerable in vitro and in vivo data demonstrating a decrease in cytochrome P450 (CYP) activity in inflammation and infection, clinically, traumatic brain injury (TBI) results in an increase in CYP and UDP glucuronosyltransferases (UGT) activity. The objective of this study was to determine the effects of TBI alone and along with treatment with either erythropoietin (EPO) or anakinra on gene expression of hepatic inflammatory proteins and drug metabolizing enzymes and transporters in a cortical contusion impact (CCI) injury animal model. Microarray-based transcriptional profiling was used to determine the effect on gene expression at 24 h, 72 h and 7 days post-CCI.

View SamplesThe normal growth and function of mammary epithelial cells depend on interactions with the supportive stroma. Alterations in this communication can lead to the progression or expansion of malignant growth. The human mammary gland contains two distinctive types of fibroblasts within the stroma. The epithelial cells are surrounded by loosely connected intralobular fibroblasts, which are subsequently surrounded by the more compacted interlobular fibroblasts. The different proximity of these fibroblasts to the epithelial cells suggests distinctive functions for these two subtypes. In this report, we compared the gene expression profiles between the two stromal subtypes.

View SamplesSeven novel and potent Raf small molecule kinase inhibitors were evaluated in 7-day oral repeat-dose rat toxicity studies. All compounds tested induced hyperplasia in multiple tissues. Microarrays were used to investigate transciptional changes associated by treatment with a single compound to gain insight into the cellular changes that may contribute to the tissue hyperplasia.

View SamplesThe tumor suppressor gene RASSF1A (Ras association domain family protein 1A) coding for a microtubule stabilizing protein is epigenetically silenced in most human cancers. As a binding partner of the kinases MST1 and MST2, the mammalian orthologues of the Drosophila Hippo kinase, RASSF1A is a potential regulator of the Hippo tumor suppressor pathway. RASSF1A shares these properties with the scaffold protein SAV1. The role of this pathway in human cancer has remained enigmatic because Hippo pathway components are rarely mutated. Rassf1a homozygous knockout mice developed liver tumors. However, heterozygous deletion of Sav1 or co-deletion of Rassf1a and Sav1 produced liver tumors with much higher efficiency than single deletion of Rassf1a. Analysis of RASSF1A binding partners by mass spectrometry identified the Hippo kinases MST1, MST2 and the oncogenic IkB kinase TBK1 as the most significantly enriched RASSF1A-interacting proteins. The transcriptome of Rassf1a-/- livers was more deregulated than that of Sav1+/- livers and the transcriptome of Rassf1a-/-, Sav1+/- livers was similar to that of Rassf1a-/- mice. We found that the levels of Tbk1 protein were substantially upregulated in livers lacking Rassf1a, and at the transcript level, factors regulating Tbk1 stability, including Usp2 and Dtx4, were also dysregulated. Furthermore, transcripts of several beta tubulin isoforms were increased in the Rassf1a-deficient liver genotypes presumably reflecting a role of Rassf1a as a tubulin-binding and microtubule-stabilizing protein. Our data suggest a multifactorial role of Rassf1a in suppression of liver carcinogenesis.
