Flavonoids are a broadly distributed class of plant pigments, universally present in vascular plants and responsible for much of the coloring in nature. They are strong antioxidants that occur naturally in foods and can inhibit carcinogenesis in rodents. In this study, we examined acacetin (5,7-dihydroxy-4'-methoxyflavone), a flavonoid compound, for its effect on proliferation in a human liver ...

5-(2'-oxoheptadecyl)-resorcinol [structure: see text] and 5-(2'-oxononadecyl)-resorcinol [structure: see text] were isolated from fermentations of an imperfect basidiomycete. The structures of the compounds were determined by spectroscopic techniques. Both compounds exhibit cytotoxic effects against the human colon tumor cell lines COLO-320, DLD-1 and HT-29 and the human promyeloid leukemia cel...

Antrodia camphorata is a well-known medicinal mushroom in Taiwan and has been studied for decades, especially with focus on anti-cancer activity. Polysaccharides are the major bioactive compounds reported with anti-cancer activity, but the debates on how they target cells still remain. Research addressing the encapsulation of polysaccharides from A. camphorata extract (ACE) to enhance anti-canc...

The metalloproteome is defined as the set of proteins that have metal-binding capacity by being metalloproteins or having metal-binding sites. A different metalloproteome may exist for each metal. Mass spectrometric characterization of metalloproteomes provides valuable information relating to cellular disposition of metals physiologically and in metal-associated diseases. We examined the Cu an...

The activation of LDL receptors was described recently in a human hepatoma cell line (Hep G2) exposed both to alpha + alpha' subunits from 7S soy globulin and to Croksoy(R)70, a commercial isoflavone-poor soy concentrate. To assess the final identity of the peptide(s) putatively responsible for the biochemical effect, experiments were performed in Hep G2 cells, exposed either to synthetic pepti...

We motivate and summarize our analysis of hep-th/0610276 in which we consider D7-brane probe embeddings in the Polchinski-Strassler background with N = 2 supersymmetry. The corresponding dual gauge theory is given by the N = 2 theory with fundamental matter. Based on a talk given by C. Sieg at the RTN Workshop 2006, Napoli. ∗[email protected], [email protected], [email protected], [email protected]...

An optimized method for the synthesis of new 2-substituted-thiazolo[2,3-a]benzimidazole-3(2H)-ones was developed which enabled the target compounds to be obtained in relative good yields through one pot process.Four cancer cell lines: human colorectal cancer cell line HT-29, breast cancer cells MDA-MB-231, cervical cancer cells HeLa, human liver carcinoma cell line HepG2 and human diploid cell ...

There is little information regarding the molecular mechanisms of hepatocarcinogenesis. We studied the p53 gene at the DNA, RNA, and protein level in seven human hepatocellular carcinoma (HCC)-derived cell lines; six of seven showed p53 abnormalities. By Southern blotting, the p53 gene was found to be partially deleted in Hep 3B and rearranged in SK-HEP-1 cells. Transcripts of the p53 gene were...
