PPARalpha signaling mediates the synergistic cytotoxicity of clioquinol and docosahexaenoic acid in human cancer cells. - .[Biochem Pharmacol. 2009] - PubMed Result - 0 views

  •  
    The combination effects index (CI) analysis confirmed the synergy of clioquinol and clofibrate on inhibiting cancer cell viability. Using inhibitors to block PPARalpha signaling diminished the synergistic cytotoxicity of clioquinol and DHA. These results provide pharmacological evidence that the synergistic anticancer action of clioquinol and DHA is mediated by PPARalpha signaling in human cancer cells. PPARalpha signaling mediates the synergistic cytotoxicity of clioquinol and docosahexaenoic acid in human cancer cells. Tuller ER, Brock AL, Yu H, Lou JR, Benbrook DM, Ding WQ.

Exapation of an ancient Alu short interspersed element provides a highly conserved vitamin D-mediated innate immune response in humans and primates - BioMed Central | Full text - 0 views

  •  
    Conclusion We demonstrated that the VDRE in the CAMP gene originated from the exaptation of an AluSx SINE in the lineage leading to humans, apes, OWMs and NWMs and remained under purifying selection for the last 55-60 million years. We present convincing evidence of an evolutionarily fixed, Alu-mediated divergence in steroid hormone nuclear receptor gene regulation between humans/primates and other mammals. Evolutionary selection to place the primate CAMP gene under regulation of the vitamin D pathway potentiates the innate immune response and may counter the anti-inflammatory properties of vitamin D. Exaptation of an ancient Alu short interspersed element provides a highly conserved vitamin D-mediated innate immune response in humans and primates. Gombart AF, Saito T, Koeffler HP.

Melanoma growth is reduced in fat-1 transgenic mice: Impact of omega-6/omega-3 essential fatty acids - Proc Natl Acad Sci U S A. 2006 Aug 15;103(33):12499-504 (full text) - 0 views

    Melanoma growth is reduced in fat-1 transgenic mice: impact of omega-6/omega-3 essential fatty acids. Xia S, Lu Y, Wang J, He C, Hong S, Serhan CN, Kang JX. Proc Natl Acad Sci U S A. 2006 Aug 15;103(33):12499-504. Epub 2006 Aug 3. PMID: 16888035 doi: 10.1073/pnas.0605394103 In vitro experiments showed that addition of the n-3 fatty acid eicosapentaenoic acid or PGE(3) inhibited the growth of B16 cell line and increased the expression of PTEN, which could be partially attenuated by inhibition of PGE(3) production, suggesting that PGE(3) may act as an antitumor mediator. These data demonstrate an anticancer (antimelanoma) effect of n-3 fatty acids through, at least in part, activation of PTEN pathway mediated by PGE(3).

Conjugated Linoleic Acid Promotes Human Adipocyte Insulin Resistance through NFκB-dependent Cytokine Production - JBC - 0 views

    Conjugated linoleic acid promotes human adipocyte insulin resistance through NFkappaB-dependent cytokine production. Chung S, Brown JM, Provo JN, Hopkins R, McIntosh MK. J Biol Chem. 2005 Nov 18;280(46):38445-56. Epub 2005 Sep 9. PMID: 16155293 doi: 10.1074/jbc.M508159200 Collectively, these data demonstrate for the first time that trans-10, cis-12 CLA promotes NFkappaB activation and subsequent induction of IL-6, which are at least in part responsible for trans-10, cis-12 CLA-mediated suppression of peroxisome proliferator-activated receptor gamma target gene expression and insulin sensitivity in mature human adipocytes. In summary, our in vitro data demonstrate that a physiological level of trans-10, cis-12 CLA activates NFκB- and ERK1/2-dependent cytokine production, which together suppress PPARγ and Glut4 levels and lead to impaired glucose uptake. Studies are currently under way examining 1) how CLA regulates PPARγ and the expression of its target genes, 2) the specific signaling role of SV cells and adipocytes in mediating the TG-lowering actions of CLA, and 3) the CLA-induced, upstream signal that activates NFκB and ERK1/2.

    Berberine suppresses in vitro migration and invasion of human SCC-4 tongue squamous cancer cells through the inhibitions of FAK, IKK, NF-kappaB, u-PA and MMP-2 and -9. Ho YT, Yang JS, Li TC, Lin JJ, Lin JG, Lai KC, Ma CY, Wood WG, Chung JG. Cancer Lett. 2009 Jul 8;279(2):155-62. Epub 2009 Feb 28. PMID: 19251361 doi:10.1016/j.canlet.2009.01.033 There is increasing evidence that urokinase-type plasminogen activator (u-PA) and matrix metalloproteinases (MMPs) play an important role in cancer metastasis and angiogenesis. Inhibition of u-PA and MMPs could suppress migration and invasion of cancer cells. Berberine, one of the main constituents of the plant Rhizoma coptidis, is a type of isoquinoline alkaloid, reported to have anti-cancer effects in different human cancer cell lines. There is however, no available information on effects of berberine on migration and invasion of human tongue cancer cells. Here, we report that berberine inhibited migration and invasion of human SCC-4 tongue squamous carcinoma cells. This action was mediated by the p-JNK, p-ERK, p-p38, IκK and NF-κB signaling pathways resulting in inhibition of MMP-2 and -9 in human SCC-4 tongue squamous carcinoma cells. Our Western blowing analysis also showed that berberine inhibited the levels of urokinase-plasminogen activator (u-PA). These results suggest that berberine down-regulates u-PA, MMP-2 and -9 expressions in SCC-4 cells through the FAK, IKK and NF-κB mediated pathways and a novel function of berberine is to inhibit the invasive capacity of malignant cells.
