BACKGROUND: Reactive oxygen species, such as superoxide (O(2)(-)), are involved in the abnormal growth of various cell types. Angiotensin II (Ang II) is one of the most potent inducers of oxidative stress in the vasculature. The molecular events involved in Ang II-induced proliferation of vascular smooth muscle cells (VSMCs) are ... More
Efficacy of acetaminophen in skin B16-F0 melanoma tumor-bearing C57BL/6 mice.
Authors:Vad NM, Kudugunti SK, Graber D, Bailey N, Srivenugopal K, Moridani MY
Journal:Int J Oncol
PubMed ID:19513568
'Previously, we reported that acetaminophen (APAP) showed selective toxicity towards melanoma cell lines. In the current study, we investigated further the role of tyrosinase in APAP toxicity in SK-MEL-28 melanoma cells in the presence of a short hairpin RNA (shRNA) plasmid, silencing tyrosinase gene. Results from tyrosinase shRNA experiments showed ... More
Calcium regulation of matrix metalloproteinase-mediated migration in oral squamous cell carcinoma cells.
Authors:Munshi HG, Wu YI, Ariztia EV, Stack MS,
Journal:J Biol Chem
PubMed ID:12194986
'Activation of matrix metalloproteinase 2 (MMP-2) has been shown to play a significant role in the behavior of cancer cells, affecting both migration and invasion. The activation process requires multimolecular complex formation involving pro-MMP-2, membrane type 1-MMP (MT1-MMP), and tissue inhibitor of metalloproteinases-2 (TIMP-2). Because calcium is an important regulator ... More
Characterization of the human forkhead gene FREAC-4. Evidence for regulation by Wilms' tumor suppressor gene (WT-1) and p53.
Authors: Ernstsson S; Pierrou S; Hulander M; Cederberg A; Hellqvist M; Carlsson P; Enerbäck S;
Journal:J Biol Chem
PubMed ID:8702877
'We describe the cloning and sequence analysis of a nearly full-length cDNA as well as a corresponding 5.2-kilobase pair genomic fragment encoding FREAC-4, a member of the forkhead family of transcription factors. The cDNA is collinear with respect to the coding region of the intronless genomic clone. The conceptual translation ... More
Foam cell formation inhibits growth of Chlamydia pneumoniae but does not attenuate Chlamydia pneumoniae-induced secretion of proinflammatory cytokines.

Journal:Circulation
PubMed ID:11997286
'BACKGROUND: It has not yet been determined whether lipid-loaded macrophages (foam cells), a major cellular component of atherosclerotic lesions, have the capacity to support growth of Chlamydia pneumoniae and be activated to secrete proinflammatory cytokines in response to C pneumoniae infection. METHODS AND RESULTS: Lipid loading of RAW 264.7 cells ... More
