Abstract
Reciprocal rearrangements of the MLL gene are among the most common chromosomal abnormalities in both Acute Lymphoblastic and Myeloid Leukemia. The MLL gene, located on the 11q23 chromosomal band, is involved in more than 40 recurrent translocations. In the present study, we describe the development and validation of a biochip-based assay designed to provide a comprehensive molecular analysis of MLL rearrangements when used in a standard clinical pathology laboratory. A retrospective blind study was run with cell lines (n=5), and MLL positive and negative patient samples (n=31), to evaluate assay performance. The limits of detection determined on cell line data were 10(-1), and the precision studies yielded 100% repeatability and 98% reproducibility. The study shows that the device can detect frequent (AF4, AF6, AF10, ELL or ENL) as well as rare partner genes (AF17, MSF). The identified fusion transcripts can then be used as molecular phenotypic markers of disease for the precise evaluation of minimal residual disease by RQ-PCR. This biochip-based molecular diagnostic tool allows, in a single experiment, rapid and accurate identification of MLL gene rearrangements among 32 different fusion gene (FG) partners, precise breakpoint positioning and comprehensive screening of all currently characterized MLL FGs.

Abstract
The very fact that apoptosis and nonsteroidal anti-inflammatory drugs (NSAIDs) can be linked in the same title should tell you that something unusual is happening. The image of NSAIDs among physicians is certainly discordant with that associated with cancer treatment, which usually involves administration of drugs with serious or even life-threatening toxicity. In contrast, the drugs discussed in this review, including selective cyclooxygenase-2 inhibitors, lipoxygenase inhibitors, and novel NSAID derivatives (eg, sulindac sulfone and R-flurbiprofen), offer the promise of oral, nontoxic agents able to control the progression of established prostate cancer and possibly to prevent the development of prostate cancer de novo. NSAIDs were initially developed to suppress inflammation and pain by inhibiting the production of prostaglandin E2 and its metabolites. At first glance, the fact that NSAIDs are active against prostate cancer in laboratory and clinical studies might suggest that prostaglandins play a pivotal role in prostate cancer biology. However, the story is much more complex than that. Although cyclooxygenase-mediated production of prostaglandins appears to play an important role in the biology of prostate cancer, the NSAIDs and derivatives with promising activity against prostate cancer manifest several mechanisms of action that can include direct inhibition of eicosanoid formation, indirect inhibition of eicosanoid formation by inhibiting expression of enzymes involved in eicosanoid synthesis, or by interfering with the function of cyclic guanosine monophosphate.

Abstract
The formation of new blood vessels by angiogenesis to provide adequate blood supply is a key requirement for the growth of many tumors. While normal blood vessels expressed the COX-1 enzyme, new angiogenic endothelial cells expressed the inducible COX-2. We evaluated the role of COX inhibitors in the mouse corneal micropocket assay in which angiogenesis is driven by the addition of a Hydron pellet containing basic fibroblast growth factor (bFGF). Neovascular areas were measured with a slit lamp five days after pellet implantation into the corneal stroma. All animals containing implants with bFGF (90 ng) developed intensive areas of neovascularization, whereas the controls implanted with the Hydron pellet alone did not. Indomethacin (a nonselective COX-1/COX-2 inhibitor) and SC-236 (a COX-2-selective inhibitor) inhibited angiogenesis in a dose-dependent manner. Importantly, the indomethacin-treated mice developed severe gastrointestinal toxicity at the efficacious dose of 3 mg/kg/day. By contrast, gastrointestinal lesions were not observed, and platelet COX-1 activity was unaffected, at anti-angiogenic doses of SC-236 (1-6 mg/kg/day). Furthermore, a COX-1-selective inhibitor, SC-560, was ineffective at doses up to 10 mg/kg, a dose that completely blocked platelet COX-1 activity in these mice. SC-236 was also effective in reducing angiogenesis driven by bFGF, vascular endothelium growth factor (VEGF), or carrageenan in the matrigel rat model. Finally, in several tumor models, SC-236 consistently and effectively inhibited tumor growth and angiogenesis. This novel antiangiogenic activity of COX-2 inhibitors indicates their potential therapeutic utility in several types of cancer.

Abstract
OBJECTIVE Cyclooxygenase inhibitors are effective tocolytic agents, but significant adverse effects limit their use. We hypothesized that selective inhibitors of the isozyme cyclooxygenase 2 would effectively diminish labor-associated prostaglandin production. STUDY DESIGN We analyzed cyclooxygenase type 1 and 2 expression in amnion, chorion, decidua, and myometrium from laboring or nonlaboring women and tested the efficacy of selective cyclooxygenase 2 inhibition in diminishing prostaglandin production. RESULTS The expression of cyclooxygenase 2 in amnion from women in labor, either preterm or at term, was significantly higher than in amnion before labor. In contrast, cyclooxygenase 1 expression was unchanged by labor. The enhanced expression of amniotic cyclooxygenase 2 was associated with increased prostaglandin E(2) levels in laboring women. Amniotic prostaglandin E(2) production was effectively diminished by the selective cyclooxygenase 2 inhibitors SC-236 and NS-398 but not by the cyclooxygenase 1 inhibitor SC-560. CONCLUSION Selective inhibitors of cyclooxygenase 2 are effective in diminishing prostaglandin production in vitro and may be useful in prevention of preterm deliveries.
