75 of all human cancers and the corresponding premalignant states. Moreover, an anti-tumor effect of NSAIDs was detected by epidemiological and clinical evaluations and traced back mainly to an inhibition of COX-2-catalyzed prostaglandin synthesis reviewed by Marks and Fursten-berger 2000 Turini and DuBois 2002 Thun et al. 2002 Dannenberg et al. 2005 . Mechanistically, this presently represents one of the most clearcut examples of cancer chemoprevention with a particularly high potential for...
Genomic Signature Induced by hCG and Pregnancy
RNA was obtained from mammary glands of rats in their 15th and 21st day of pregnancy or hCG treatment, and 21 and 42 days postpar-tum or post-treatment, respectively. RNAs were analyzed utilizing two membranes for each animal and compared with mRNA of age-matched virgin control rats. RNAs were hybridized to cDNA array membranes that contained 5,800 rat genes Research Genetics, Huntsville, AL . Cluster analysis was performed using the Jaidexp Java Analysis information amp Data Exploration...

Abstract Axi
Early pregnancy imprints in the breast permanent genomic changes or a signature that reduces the susceptibility of this organ to cancer. The breast attains its maximum development during pregnancy and lactation. After menopause, the breast regresses in both nulliparous and parous women containing lobular structures designated Lob.1. The Lob 1 found in the breast of nullipa-rous women and of parous women with breast cancer never went through the process of differentiation, retaining a high...
Redox Status of Melanocytes and Melanoma Cells
We initially asked a simple question How do melanocytes respond to oxidative stress Meyskens et al. 1997 . The conclusions from our studies are summarized as follows, and illustrated in Fig. 1. Melanoma were exposed to a low dose of H2O2 generated by adding titered amounts of glucose oxidase to the medium, and with a fixed dose of glucose, a predictable amount of H2O2 was generated. Using UVR-B as the source of ROS was too complex as it produces many cellular effects including direct DNA...
Designer Cytokines
Construction of chimeric proteins containing modules of different proteins belonging to the IL-6R family helped us to identify cytokine binding motives on receptor proteins Kallen et al. 1999 2000 Aasland et al. 2002, 2003 . On the basis of these experiments together with other structural information available on membrane bound and soluble cytokine receptors, we designed several cytokine-cytokine receptor molecules. Covalent linkage of the domains of the IL-6 and sIL-6R that are necessary for...

ICE-like cysteine Protease Caspases Fig. 5 Postulated model of hCG-induced cell cycle arrest and apoptosis in human breast epithelial cells. In the presence of hCG for 24 h breast epithelial cells bind the hormone to a putative membrane receptor. This triggers a cascade of programmed cell death gene activation through the CAMP-PKA pathway, as well as through activation of TGF- .

Conclusions
The alternative signaling pathway of IL-6 via the sIL-6R IL-6 complex seem to be an important mechanism for the development of chronic inflammatory diseases and inflammation-associated tumor growth. The ability of selective inhibition of sIL-6R-dependent IL-6 responses with sgp130 can be used in vivo to distinguish between classical IL-6 signaling and IL-6 trans-signaling Fig. 4 . There is now clear evidence that chronic inflammatory states often lead to neoplastic lesions. Sgp130 can be used...

Virus replication and assembly is tightly linked to the differentiation program of epithelial cells.

IL6 Transsignaling and Inflammation
Many investigations have shown that IL-6 plays an important role in the transition from innate immunity to acquired immunity, a crucial event in the controlling of any inflammatory states Hurst et al. 2001 Jones 2005 Jones et al. 2005 . Disruption of this essential switch leads to an inappropriate immune response and might cause the onset of autoimmune or chronic inflammatory disorders Hoebe et al. 2004 . The disco very of the IL-6 trans-signaling mechanism may help to understand the...

between different pathways are required. Our results on combined genotypes indicate that lung cancer risk is considerably enhanced by specific combinations of variant alleles. The interaction of several or many variant repair proteins, each with only slightly reduced functional activity, may be necessary to significantly decrease DNA repair activity and to increase cancer risk. However, given the huge number of possible genotype combinations in our cohort, only some individuals with a specific...
