Affymetrix Human Genome U133A 2.0 Array (hgu133a2)
Description
Current smokers develop metastatic prostate cancer more frequently than nonsmokers, suggesting that a tobacco-derived factor induces metastasis. To identify smoking-induced alterations in human prostate tumors, we analyzed gene and protein expression of tumors from current, past, and never smokers and observed distinct molecular alterations in current smokers. Specifically, an immune and inflammation signature was identified in prostate tumors of current smokers that was either attenuated or absent in past and never smokers. Key characteristics of this signature included augmented immunoglobulin expression by tumor-infiltrating B cells, NF-kB activation, and increased interleukin-8 in tumor and blood. In an alternate approach to characterize smoking-induced oncogenic alterations, we explored the effects of nicotine in prostate cancer cells and prostate cancer-prone TRAMP mice. These experiments showed that nicotine increases both invasiveness of human prostate cancer cells and metastasis in tumor-bearing TRAMP mice, indicating that nicotine can induce a phenotype that resembles the epidemiology of smoking-associated prostate cancer progression. In summary, we describe distinct oncogenic alterations in prostate tumors from current smokers and show that nicotine can enhance prostate cancer metastasis.

Description
The pathways by which oncogenes, such as MLL-AF9, initiate transformation and leukemia in humans and mice are incompletely defined. In a study of target cells and oncogene dosage, we found that Mll-AF9, when under endogenous regulatory control, efficiently transformed LSK (Lin- Sca1+ c-kit+) stem cells while committed granulocyte-monocyte progenitors (GMPs) were transformation-resistant and did not cause leukemia. Mll-AF9 was expressed at higher levels in hematopoietic stem (HSC) than GMP cells. Mll- AF9 gene dosage effects were directly shown in experiments where GMPs were efficiently transformed by the high dosage of Mll-AF9 resulting from retroviral transduction. Mll-AF9 up-regulated expression of 196 genes in both LSK and progenitor cells, but to higher levels in LSKs than in committed myeloid progenitors.

Illumina HiSeq 2000
Description
A specific set of genes involved in regulating cellular immune response, antigen presentation, and T cell activation and survival were down-regulated 7 days after LVAD placement. 6 months following LVAD placement, the expression levels of these genes were significantly increased; yet importantly, remained significantly lower than age and sex-matched samples from healthy controls. Overall design: Examination of the effect of LVAD implant on peripheral blood transcriptome. Blood was drawn before LVAD placement, 7 days post implant, and 180 days post implant. RNA sequencing was performaed on all samples.
Publication Title
