Question: Context: p38 mitogen-activated protein kinase is associated with many clinical entities characterized by inflammation. We postulated that inhibition of p38 mitogen-activated protein kinase with FR167653 attenuates inflammation and the development of pulmonary hypertension in monocrotaline-treated rats.', 'Rats were divided into 4 groups: (1) the control group (daily 0.9% saline), (2) the FR group (daily FR167653, 2 mg . kg(-1) . d(-1)), (3) the MCT group (daily 0.9% saline the day after a single monocrotaline dose, 60 mg/kg), and (4) the MCT+FR group (daily FR167653, 2 mg . kg(-1) . d(-1), the day after a single MCT dose). Body weight, pulmonary artery pressure, and morphometric changes of the pulmonary artery with the histopathologic method were observed weekly for 4 weeks. Also, p38 mitogen-activated protein kinase activity and inflammatory cytokine expression in the lung were measured.', 'Four weeks after monocrotaline administration, mean pulmonary artery pressure in the MCT+FR group was lower than in the MCT group (MCT+FR vs MCT: 24.7 +/- 1.9 vs 36.5 +/- 2.1 mm Hg; P < .05). In morphometric analysis the percentage of medial wall thickness and the percentage of muscularization in the MCT+FR group were reduced compared with those in the MCT group after 4 weeks (P < .05); however, the number of macrophages was not significantly different. p38 mitogen-activated protein kinase activity was significantly attenuated in the MCT+FR group compared with in the MCT group (7.2 +/- 0.52 vs 2.1 +/- 0.23 fold-increase, P < .05, at 1 week). Although mRNA levels of tumor necrosis factor alpha and interleukin 1beta were reduced in the MCT+FR group compared with in the MCT group (tumor necrosis factor alpha: 1.18 +/- 0.36 vs 3.05 +/- 1.12 fold-increase, P < .05, at 2 weeks; interleukin 1beta: 2.2 +/- 0.34 vs 4.4 +/- 1.09 fold-increase, P < .05, at 1 week), FR167653 did not suppress increased monocyte chemotactic protein 1 mRNA expression induced by monocrotaline (3.2 +/- 0.62 vs 3.1 +/- 0.42 fold-increase, at 1 week).
Answer: FR167653 significantly attenuates the expression of inflammatory cytokines, ultimately preventing the progression of pulmonary hypertension. These results suggest that p38 mitogen-activated protein kinase might play a central role in the molecular events that underlie the development and progression of pulmonary hypertension.

Answer: Does specific inhibition of p38 mitogen-activated protein kinase with FR167653 attenuate vascular proliferation in monocrotaline-induced pulmonary hypertension in rats?

Question: Context: Fatty acid synthase has been shown to be over expressed in a wide range of cancers and it has emerged as a therapeutic target. We examined whether fatty acid synthase could be a novel therapeutic target for renal cell carcinoma using the pharmacological fatty acid synthase inhibitor C75 (Cayman Chemical, Ann Arbor, Michigan).', 'The effects of C75 on cell viability and proliferation in human renal cancer 769P (ATCC(R)), Caki-1 and KU20-01 cells were examined by MTS assay and cell counts. Cell cycle distribution was analyzed by flow cytometry and cell invasiveness was assessed by wound healing and Matrigel(trade mark) invasion assays. Fatty acid synthase expression and the effects of C75 on intracellular signaling pathways were analyzed by Western blotting. The antitumor efficacy of C75 was examined using Caki-1 cell xenografts.', 'All renal cancer cell lines expressed detectable fatty acid synthase. C75 (10 mug/ml) significantly inhibited cell viability and growth by arresting the cell cycle at the G2/M phase and inducing apoptosis (p <0.01). The covered area in the wound and the number of cells invading through a Matrigel chamber were significantly smaller for cells treated with C75 than they were for control cells treated with vehicle (p <0.001). C75 suppressed Her2 and epidermal growth factor receptor expression as well as STAT3 phosphorylation, while increasing p53 and p21(Waf1/Cip1) expression. Intraperitoneal administration of C75 at doses of 20 mg/kg per week for 28 days significantly reduced the tumor volume of Caki-1 xenografts (p <0.05).
Answer: Pharmacological inhibition of fatty acid synthase could be an effective strategy for treating renal cell carcinoma.

Answer: Does pharmacological inhibitor of fatty acid synthase suppress growth and invasiveness of renal cancer cells?

Question: Context: Paraoxonase-1 (PON1) is an enzyme that prevents low-density lipoprotein (LDL) oxidation. The role of polymorphisms of PON1 determining early atherosclerotic changes is currently unclear.', 'Cross sectional cohort study.', 'Nine hundred and ninety-nine subjects from a population-based cohort were screened. Intima-media thickness (IMT) was measured by ultrasonography. Leu-Met55 and Gln-Arg192 polymorphism were determined.', 'No association between PON1 genotypes and IMT was found. This finding remained after adjusting for confounding factors.
Answer: The PON1 Leu-Met55 and Gln-Arg192 polymorphisms are not major risk factors for atherosclerosis in the general Caucasian population.

Answer:
Are paraoxonase-1 gene Leu-Met55 and Gln-Arg192 polymorphisms associated with carotid artery atherosclerosis in a population-based cohort?
